There's no magic behind laser skin rejuvenation—just solid science. When laser energy targets your skin, it creates controlled micro-injuries that trigger your body's natural healing response. This process stimulates new collagen production, the protein responsible for skin's firmness and elasticity. As we age, our natural collagen production decreases by about 1% each year after age 20, contributing to those fine lines and wrinkles you may be noticing.
Unlike creams that work on the surface, lasers penetrate to deeper skin layers where real change happens. Think of it as pressing the "reset button" on your skin cells, encouraging them to behave more like they did in your youth.
The beauty of modern laser technology lies in its precision. Today's devices can target specific skin concerns without damaging surrounding tissues, allowing for customized treatments based on your unique needs.
My name is Rachel Stone, and as a Licensed Medical Aesthetician and Certified Laser Technician with over a decade of experience, I've helped hundreds of clients achieve remarkable results through laser for skin rejuvenation treatments at MD Body and Med Spa. I'm passionate about educating patients on how these advanced technologies can transform their skin without surgery.
How Laser Skin Rejuvenation Works
When you hear the scientific term "selective photothermolysis," it might sound complicated, but the concept is actually quite neat. Laser for skin rejuvenation works by using specific wavelengths of light that target particular structures in your skin while leaving surrounding tissues untouched – like having a conversation with just one person in a crowded room.
As the laser energy penetrates your skin, it transforms into heat at precisely the right depth. This creates tiny columns of treated tissue (we call them thermal micro-columns) surrounded by healthy skin. Think of it as creating thousands of microscopic healing zones. Your body, being the amazing self-healer it is, immediately recognizes these micro-injuries and kicks into action.
First, your existing collagen contracts, giving an immediate tightening effect. Then, damaged skin cells are cleared away to make room for healthy new ones. The real magic happens next – your body begins producing fresh collagen (a process called neocollagenesis) and boosts elastin production. Over the following months, this dermal remodeling continues, with the most dramatic improvements typically appearing 3-6 months after treatment as your new collagen matures and strengthens.
Research published in scientific studies on fractional photothermolysis confirms what we see in our clients every day – this controlled healing response creates meaningful, lasting improvements in skin quality.
The Science Behind a "Laser for Skin Rejuvenation"
Different lasers target different "chromophores" (light-absorbing molecules) in your skin, which is why we can customize treatments to your specific concerns:
Water molecules are the primary target for most skin rejuvenation lasers. When light energy hits water in your skin cells, it creates that controlled wound-healing response we're looking for. This is particularly effective because water is abundant in your skin – making up about 70% of your dermis.
The beauty of this controlled healing process is that we're essentially partnering with your body's natural regenerative abilities. Rather than forcing change from the outside (like topical products), laser for skin rejuvenation triggers your skin to rebuild itself from within – stronger, healthier, and more youthful.
Benefits Unique to a "Laser for Skin Rejuvenation" Treatment
What makes laser treatments so special is their ability to address multiple concerns simultaneously and reach depths that topical products simply cannot.
When it comes to fine lines and wrinkles, lasers don't just mask them – they help fill them in from the inside out by stimulating collagen deep within the dermis. Your skin texture becomes noticeably smoother as damaged surface cells are removed and new cell growth is encouraged.
If you're troubled by sun spots or age spots, you'll love how targeted energy breaks down excess melanin, gradually fading these discolorations. Even stubborn scars can be improved as laser energy remodels scar tissue, helping it blend better with surrounding skin.
Many clients are surprised to see their pores appear smaller after treatment. This happens because the heat-induced collagen tightens the skin around pores, creating a more refined appearance. And the overall skin tightening effect from collagen contraction and regeneration can give your face a subtly lifted, more youthful look.
At MD Body and Med Spa, I've seen hundreds of clients amazed by how one technology can address so many concerns at once. A single fractional treatment can improve both texture and pigmentation while setting the stage for months of continued collagen development – giving you both immediate satisfaction and long-term results.
Comparing Laser Modalities & Light-Based Options
Not all lasers are created equal. At MD Body and Med Spa in Greenwood Village, CO, we offer several different laser for skin rejuvenation technologies to address various skin concerns and accommodate different recovery timeframes.
Ablative vs Non-Ablative: Depth, Downtime, Results
When you're considering laser for skin rejuvenation, understanding the difference between ablative and non-ablative treatments helps set realistic expectations for both results and recovery.
Ablative lasers work by essentially vaporizing the outer skin layers while heating deeper tissues. Think of them as the power players in the laser world. Our CO₂ lasers (operating at 10,600 nm) and Erbium:YAG lasers (2,940 nm) fall into this category. They're your best option if you're dealing with moderate to severe wrinkles, significant sun damage, acne scars, or noticeable skin laxity.
The trade-off for these dramatic results? You'll need to plan for some downtime – typically 1-2 weeks with CO₂ treatments or 5-7 days with Erbium:YAG. During recovery, expect some redness, swelling, and peeling. The good news? Most patients need just 1-2 sessions to see remarkable improvement.
Non-ablative lasers take a gentler approach. They bypass the surface skin and deliver heat to the dermis without damaging your epidermis. Our Nd:YAG (1064 nm), Diode (1450 nm), and Erbium Glass (1540 nm) lasers work this way. These treatments are perfect if you're addressing mild wrinkles, early aging signs, subtle skin laxity, or redness.
The major advantage here is minimal downtime – usually just 24-48 hours of mild redness and swelling. The results develop more gradually over 2-3 months, and you'll typically need 3-5 sessions to achieve your goals.
As Dr. Joel Cohen, a renowned dermatologist, explains: "Ablative lasers remove skin surface layers to stimulate deeper tissue healing, while non-ablative lasers penetrate without surface damage, reducing or eliminating downtime."
Fractional Technology: Microscopic Treatment Zones
The introduction of fractional technology in 2004 was truly a game-changer for laser for skin rejuvenation. Instead of treating the entire skin surface, fractional lasers create thousands of microscopic treatment zones (MTZs) while leaving surrounding tissue intact.
This approach is like aerating a lawn – treating specific columns of skin while leaving healthy bridges in between. These tiny thermal columns extend from the epidermis into the dermis, stimulating collagen production while the surrounding healthy tissue supports rapid healing.
The beauty of fractional technology lies in its balance of effectiveness and safety. Your skin heals much faster because the untreated areas accelerate recovery of the treated zones. This means reduced risk of side effects, the ability to treat more aggressively with less downtime, and versatility across both ablative and non-ablative platforms.
According to research published in the journal Assessment of Laser Effects on Skin Rejuvenation, fractional lasers can penetrate to depths of 1 mm (non-ablative) to 2.5 mm (ablative), allowing us to customize your treatment based on the severity of your skin concerns.
Intense Pulsed Light (IPL): Broad-Spectrum Alternative
While not technically a laser, Intense Pulsed Light (IPL) deserves mention in our discussion of light-based skin rejuvenation options.
Unlike lasers that emit a single wavelength of light, IPL devices deliver multiple wavelengths (polychromatic light) and use cut-off filters to target specific concerns. This makes IPL particularly effective for addressing both pigmentation issues and vascular problems in the same treatment.
IPL works by delivering broad-spectrum light pulses that are absorbed by melanin (responsible for brown spots) and hemoglobin (causing redness). The light energy converts to heat, breaking down the targeted pigment or blood vessels while leaving surrounding tissue unharmed.
IPL treatments are generally gentler than laser procedures, with minimal downtime – usually just a few hours of mild redness. At MD Body and Med Spa, we often recommend IPL as a starter treatment for patients new to light-based therapies or as part of a comprehensive treatment plan that may include other laser modalities.
Candidacy, Preparation & In-Office Experience
Before recommending any laser for skin rejuvenation treatment, we conduct a thorough consultation to determine if you're an ideal candidate and which modality will best address your concerns.
Who Makes an Ideal Candidate for Laser Skin Rejuvenation
Good candidates for laser skin rejuvenation typically:
- Have realistic expectations about results
- Are in good general health
- Show signs of photoaging, fine lines, or uneven skin tone
- Are willing to follow pre- and post-treatment instructions
- Can commit to proper sun protection
While laser treatments can benefit many skin types, certain factors may limit your options:
Fitzpatrick Skin Types:
- Types I-III (fair to medium) - Generally good candidates for all laser types
- Types IV-VI (olive to dark) - May require specialized protocols, particularly with ablative lasers
- Darker skin tones have higher risk of post-inflammatory hyperpigmentation
Contraindications:
- Active skin infections or open wounds
- History of keloid scarring
- Certain autoimmune disorders
- Pregnancy
- Recent use of isotretinoin (Accutane) within 6-12 months
- Current use of photosensitizing medications
As one dermatologist in our research noted: "Darker-skinned patients benefit more from a slow, gradual laser approach to avoid overtreatment." At MD Body and Med Spa, we take special care to customize treatments for all skin types to ensure safety and efficacy.
Pre-Treatment Checklist
To prepare for your laser for skin rejuvenation treatment, we recommend:
2-4 Weeks Before:
- Avoid sun exposure and tanning (including self-tanners)
- Discontinue retinoids, glycolic acids, and other potentially irritating skincare products
- Begin using recommended pre-treatment products if prescribed
- Stop smoking to improve healing capacity
1 Week Before:
- Avoid blood-thinning medications and supplements (aspirin, ibuprofen, vitamin E, fish oil) if approved by your primary physician
- Continue strict sun avoidance and SPF use
- Avoid chemical peels or other skin treatments
Day of Treatment:
- Arrive with clean skin (no makeup, lotions, or creams)
- Wear comfortable clothing
- Arrange for transportation if receiving sedation for aggressive treatments
For certain patients, we may also prescribe:
- Antiviral medication if you have a history of cold sores (herpes simplex)
- Antibiotics for more aggressive treatments
- Anti-anxiety medication for comfort during the procedure
What Happens During Your "Laser for Skin Rejuvenation" Session
When you arrive at MD Body and Med Spa for your laser treatment, here's what to expect:
Preparation (30-45 minutes):
- Photos are taken for before/after comparison
- Skin is thoroughly cleansed
- Topical numbing cream is applied (sits for 30-45 minutes)
- Eye protection is provided
Treatment (15-90 minutes depending on area and type):
- The laser handpiece is moved methodically across the treatment area
- You'll feel sensations ranging from mild warmth to what many describe as a "snapping rubber band" feeling
- Chilled air may be blown on the skin for comfort
- Your provider will communicate with you throughout the process
Immediate Post-Care (15 minutes):
- Cooling compresses are applied to soothe the skin
- Initial post-care products are applied
- Detailed aftercare instructions are reviewed
The sensation during treatment varies significantly based on the laser type:
- Ablative lasers: More intense sensation, often described as heat and pinpricks
- Non-ablative lasers: Mild to moderate discomfort, often described as warmth and mild stinging
- Fractional lasers: Variable depending on settings, typically a sensation of heat and pressure
- IPL: Mild snapping sensation with minimal discomfort
As one patient described it: "It feels like a warm rubber band snap, uncomfortable but totally manageable with the numbing cream."
Recovery, Risks, Results & Costs
The journey after your laser for skin rejuvenation treatment is just as important as the procedure itself. Let me walk you through what to expect during recovery, potential risks, the results you can look forward to, and what kind of investment you're looking at.
Downtime & Aftercare Essentials
Recovery varies dramatically depending on which laser treatment you've chosen. If you opt for an ablative laser, expect a more intensive healing process. The first few days will bring noticeable redness, swelling, and some oozing – all completely normal signs your skin is beginning its change. Around days 4-7, you'll notice tiny micro-crusts forming (please resist the urge to pick at them!). By the second week, your skin will begin peeling naturally, revealing fresher skin underneath. A gentle pinkness may linger for 2-4 weeks, with full healing and collagen remodeling continuing for 4-6 weeks.
Non-ablative treatments are much gentler on recovery. Most patients experience mild redness and swelling (similar to a light sunburn) for about 24 hours, with possible mild flaking over the next couple of days. Most people return to normal activities within 48 hours, with complete recovery within a week.
Regardless of your treatment type, proper aftercare is crucial for optimal results. Gentle cleansing with only recommended products keeps the healing skin clean without irritation. Keeping your skin moisturized with provider-recommended ointments or creams prevents uncomfortable dryness and supports healing.
Sun protection becomes absolutely non-negotiable after laser treatments – we recommend a broad-spectrum SPF 50+ and physical avoidance of direct sunlight during the healing phase. Remember to let your skin heal naturally without picking or scrubbing, and avoid hot showers, saunas, and vigorous exercise until your provider gives you the green light.
For our ablative treatment patients, we may also recommend diluted vinegar soaks to prevent infection, specific medications to support healing, and scheduled follow-ups so we can monitor your progress personally.
Potential Risks & How Providers Minimize Them
While laser for skin rejuvenation has an excellent safety profile in skilled hands, it's important to understand both common side effects and potential risks. Expected temporary effects include redness, swelling, some mild bruising (especially with treatments targeting blood vessels), dryness, and peeling. Some pigmented areas may temporarily darken before flaking away – this is actually a sign the treatment is working!
Less common risks include infection (rare with proper aftercare), prolonged redness, development of acne or tiny white bumps called milia, changes in skin pigmentation (either darkening or lightening), and very rarely, scarring.
At MD Body and Med Spa, patient safety is our top priority. We minimize these risks through comprehensive pre-treatment assessments, using conservative settings for first-time patients, performing patch tests when appropriate, and developing customized protocols based on your specific skin type and concerns. We'll arm you with detailed aftercare instructions and provide prompt attention should any complications arise.
As one dermatologist noted in our research: "The wide range of biological events triggered by lasers implies that more safety considerations should be integrated into therapeutic guidelines." We take this seriously, continuously updating our protocols based on the latest research and best practices.
Results: How Many Treatments, How Long They Last
One of the most common questions I hear is, "How many treatments will I need?" The answer depends on several factors: the type of laser used, the severity of your skin concerns, your body's natural healing capacity, your diligence with aftercare, and lifestyle factors like smoking and nutrition.
For ablative lasers, most patients achieve dramatic improvement with just 1-2 treatments spaced 6-12 months apart. Non-ablative and fractional lasers typically require 3-5 sessions spaced several weeks apart for optimal results. IPL treatments also usually follow a 3-5 session protocol with 3-4 weeks between treatments.
The timeline for visible improvement varies too. With ablative lasers, you'll notice initial improvement once healing completes (2-3 weeks), with continued improvement for up to 6 months as collagen rebuilds. Non-ablative results appear more gradually, starting around 4-6 weeks and improving throughout your treatment series. Fractional lasers offer some immediate improvement with continued improvement for months afterward. With IPL, you'll typically see pigment darken and flake off within 1-2 weeks, with cumulative improvement after each session.
The good news? Results from quality laser for skin rejuvenation treatments can last for several years. However, your skin continues its natural aging process, and new sun damage can affect your results over time. Most patients maintain their refreshd appearance with annual touch-up treatments, a consistent home skincare regimen, and diligent sun protection.
Cost Breakdown & Financing Options
Investing in your skin's health and appearance is exactly that – an investment. The cost of laser for skin rejuvenation varies based on the specific technology, treatment area size, number of sessions needed, geographic location, and provider expertise.
As a general guideline, ablative laser treatments typically range from $1,500-$3,000 per full-face session. Non-ablative lasers usually cost between $800-$1,500 per session, while fractional laser treatments average $1,000-$2,500. IPL treatments are generally more affordable at $400-$600 per session.
According to the American Society of Plastic Surgeons, the 2020 national average cost was approximately $2,509 for ablative and $1,445 for non-ablative treatments.
At MD Body and Med Spa, we understand these treatments represent a significant investment. That's why we offer several ways to make them more accessible, including package discounts for multiple sessions, membership programs with preferred pricing, flexible payment plans through partners like CareCredit, and seasonal promotions on certain treatments.
We believe in complete transparency with our pricing. During your consultation, we'll provide a detailed cost breakdown with no hidden fees or surprise charges. Your skin deserves the best care possible, and we're committed to helping you achieve that in a way that works for your budget.

Emerging Technologies on the Horizon
The field of laser skin rejuvenation continues to evolve rapidly. Some exciting developments include:
Hybrid Wavelength Systems: Recent research published in Medicina demonstrates the effectiveness of dual-wavelength systems that combine CO2 and 1540 nm wavelengths. These hybrid systems deliver both ablative and non-ablative benefits in a single pass, potentially improving results while reducing downtime.
Picosecond Fractional Lasers: These ultra-short pulse duration lasers (measured in trillionths of a second) cause less thermal damage while effectively targeting pigmentation and stimulating collagen. They're showing promise for treating a wider range of skin types with minimal downtime.
AI-Guided Treatment Settings: Artificial intelligence is beginning to play a role in optimizing laser parameters based on individual skin characteristics, potentially improving safety and efficacy.
Real-Time Thermal Imaging: Advanced monitoring systems allow providers to visualize skin temperature during treatment, ensuring optimal energy delivery while preventing overtreatment.
Combined Modality Approaches: Research increasingly supports the benefits of combining different laser and light technologies in the same treatment session or series. For example, starting with BBL (broadband light) to address pigmentation, following with HALO (hybrid fractional laser) for deeper remodeling, and finishing with Moxi for fine-tuning texture.
At MD Body and Med Spa, we continuously evaluate emerging technologies to ensure we offer the most effective and safe options for our patients in Greenwood Village and the greater Denver area.
Frequently Asked Questions about Laser for Skin Rejuvenation
Is laser skin rejuvenation painful?
When patients ask me about pain during laser for skin rejuvenation treatments, I always give them the honest answer: it's uncomfortable, but manageable. The sensation varies quite a bit depending on which laser we're using.
With ablative lasers, you'll feel more intense heat or sharp pinpricks—these are our most powerful treatments. Don't worry though! We make sure you're comfortable with topical numbing creams, cooling devices, and sometimes even oral medications if needed.
Non-ablative treatments tend to be much gentler. Most of my patients describe it as a warm snapping feeling against their skin. Our topical numbing cream usually takes care of any discomfort.
Fractional lasers fall somewhere in between, with the sensation depending on the settings we use for your specific concerns. And IPL? That's typically our most comfortable option—just mild snapping sensations that most people tolerate very well.
I love how one of my recent patients put it: "I was nervous about pain, but with the numbing cream, it just felt warm with occasional zings—totally manageable and worth it for the results." That sums it up perfectly!
Can darker skin tones be treated safely?
Yes! This is one of my favorite myths to bust. While it's true that historically, darker skin tones (Fitzpatrick types IV-VI) weren't considered ideal candidates for laser treatments, technology has come a long way.
Today, with the right provider and appropriate technology, laser for skin rejuvenation can absolutely be safe for all skin tones. The key is working with someone who understands the unique considerations for melanin-rich skin.
For our patients with deeper skin tones, we typically recommend non-ablative Nd:YAG (1064 nm) lasers, certain fractional devices, and gentler non-ablative treatments. These options work beautifully while minimizing the risk of pigmentation changes.
At MD Body and Med Spa, we take extra precautions with darker skin tones, including thorough consultations, patch testing, conservative initial settings, and specialized pre/post-treatment protocols. We often recommend multiple gentle sessions rather than fewer aggressive ones—it's safer and the results are gorgeous.
As one dermatologist I deeply respect puts it: "People with darker skin should use a slow, gradual approach to avoid overtreatment and work with a highly skilled provider." That's exactly the philosophy we accept here.
How soon will I see visible changes?
This is probably the question I hear most often in consultations! The timeline for results from laser for skin rejuvenation really depends on which treatment you choose.
With ablative lasers (our most intensive option), you'll need about 7-14 days for initial healing. You'll start seeing noticeable improvements in texture and tone around the 2-3 week mark, but—and this is the exciting part—your skin continues improving for 3-6 months as new collagen develops.
Non-ablative treatments offer nearly zero downtime (a huge plus for busy people!), but results appear more gradually. Most patients notice changes beginning around 4-6 weeks, with optimal results after completing their full series of 3-5 treatments. Your skin will continue improving for 3-6 months after your final session.
Fractional lasers offer a middle ground with 3-7 days of healing time. You'll see initial improvements within 1-2 weeks, and then progressive improvement over the next 3-6 months as collagen remodeling occurs.
IPL works a bit differently—pigmented spots darken initially (don't panic, this is good!), then flake off within 5-7 days. Many patients see visible improvement after just one session, with results building with each treatment.
What I love telling my patients is that while you'll see some immediate "wow" moments after healing, the most dramatic changes often happen 3-6 months later when that fresh collagen has fully matured. It's like your skin keeps getting better and better, long after your treatment day!
Conclusion
When it comes to turning back the clock on aging skin, laser for skin rejuvenation stands as one of modern aesthetics' greatest achievements. It's not just about looking better—it's about using your body's own healing abilities to create real, lasting change from within.
I've seen how these treatments transform not just skin, but confidence. At MD Body and Med Spa in Greenwood Village, we believe everyone's skin tells a unique story. That's why we never take a one-size-fits-all approach. Your treatment plan should be as individual as you are, taking into account your skin's specific needs, your healing capacity, and the lifestyle you lead.
Maybe you're just noticing those first fine lines and want to address them before they deepen. Or perhaps you're ready to tackle more significant concerns with a more intensive approach. Either way, we have options that can work for you, delivered by professionals who genuinely care about your results.
Success with laser for skin rejuvenation comes down to several key factors. First, matching the right technology to your specific concerns—something our experts excel at. Second, working with providers who have the experience and training to deliver safe, effective treatments. Third, following through with proper pre- and post-care (those instructions really do matter!). And finally, protecting your investment with good skincare habits and sun protection.
While you'll likely notice improvement after just one session, the most dramatic changes typically come from a thoughtfully planned series of treatments. Think of it as a journey rather than a quick fix—one that leads to healthier, more vibrant skin that continues to improve over time.
I believe everyone deserves to feel comfortable and confident in their skin. If you're curious about what laser for skin rejuvenation could do for you, I'd love to meet you for a personalized consultation. We'll discuss your goals, examine your skin, and develop a plan that makes sense for your life and budget.
