Fractional Lasers Explained: How Tiny Beams Make Big Changes
Understanding the Revolutionary World of Fractional Laser Treatments
Fractional laser skin rejuvenation is a cutting-edge cosmetic procedure that creates thousands of microscopic treatment zones in the skin to stimulate collagen production and reveal fresher, younger-looking skin.
Quick Facts About Fractional Laser Skin Rejuvenation:
How it works: Creates tiny columns of controlled injury while leaving surrounding tissue intact
Common uses: Fine lines, wrinkles, acne scars, sun damage, pigmentation issues
Treatment time: 20-45 minutes per session
Recovery: 1-7 days depending on laser type (non-ablative vs. ablative)
Sessions needed: Typically 3-5 treatments spaced 2-4 weeks apart
Results: Progressive improvement with optimal results visible 2-3 months after final treatment
Average cost: $1,255 per session (range: $250-$2,500)
Have you ever stood in front of the mirror, wishing those fine lines, acne scars, or sun spots would just disappear? You're not alone. Many of us dream of smoother, more radiant skin without the lengthy downtime of traditional laser treatments.
Fractional laser technology represents a breakthrough in skin rejuvenation. Unlike traditional lasers that treat the entire skin surface, fractional lasers create microscopic columns of treatment—treating just 25-40% of your skin in a single session while leaving surrounding tissue intact. This approach stimulates your body's natural healing process, resulting in new collagen formation and healthier skin with significantly less downtime.
My name is Rachel Stone, and as a Certified Laser Technician with over a decade of experience specializing in fractional laser skin rejuvenation, I've witnessed the transformative results these treatments can achieve when delivered with precision and customized to each patient's unique needs.
Fractional Laser Skin Rejuvenation 101
Imagine a technology that can turn back the clock on your skin without weeks of hiding at home. That's exactly what fractional laser skin rejuvenation offers—a approach to skin renewal that changed everything when it was introduced in 2003.
The genius behind this treatment lies in its name: "fractional" means these lasers treat only a fraction of your skin during each session—typically just 25-40%. The rest remains untouched, creating a patchwork of treated and untreated areas that work together to speed healing and minimize downtime.
"Fractional lasers represent a true paradigm shift in laser resurfacing," explains Dr. Max Lehfeldt, a respected authority in laser treatments. "They've completely supplanted traditional non-fractional lasers in aesthetic practice due to their superior safety profile and reduced downtime."
How Fractional Laser Skin Rejuvenation Works
When you undergo fractional laser skin rejuvenation, the device creates thousands of microscopic treatment zones (MTZs)—tiny channels of controlled damage that trigger your body's natural healing response.
Think of these MTZs as little columns of renewal that extend from your skin's surface down to the deeper layers:
First, they work through your epidermis, removing old, damaged cells from the surface. Then, they reach your dermis, where all the magic happens with collagen and elastin production.
Your body responds to these micro-injuries by pushing out damaged tissue and generating fresh, new cells. Meanwhile, special cells called fibroblasts kick into high gear, producing new collagen and elastin that continue to improve your skin for months after treatment.
"What makes fractional technology so effective is that it harnesses the body's own healing response," notes Dr. Shelton, a dermatologist specializing in laser treatments. "The intact tissue surrounding each MTZ serves as a reservoir of healthy cells that accelerate the repair process."
The result? Your skin rebuilds itself from the inside out, with progressive improvement that looks completely natural.
Fractional vs. Traditional Laser Resurfacing
To truly appreciate why fractional technology has become the gold standard, let's compare it with older approaches:
Traditional ablative lasers like CO2 and Erbium:YAG remove your entire skin surface at once. While they deliver dramatic results for deep wrinkles and severe sun damage, they come with significant drawbacks: 2-4 weeks of recovery, higher risks of complications, and often the need for sedation or anesthesia.
Traditional non-ablative lasers heat the deeper skin layers without removing the surface. While they offer minimal downtime, they typically provide modest results that require numerous treatments to achieve noticeable improvement.
Fractional lasers give you the best of both worlds. By treating only a fraction of the skin at once, they deliver impressive results with just 1-7 days of recovery (depending on the specific technology and settings). They can be either ablative or non-ablative in approach, allowing for customized treatment based on your specific needs and downtime tolerance.
As one patient shared about her experience: "After about 4-6 weeks, my skin was transformed. The downtime was manageable—nothing like what my mother went through with her full CO2 resurfacing years ago."
This isn't just anecdotal. Scientific research on fractional technology shows these approaches can achieve 50-75% of the results of traditional ablative lasers with significantly less downtime and risk.
At MD Body and Med Spa, we've acceptd fractional technology because it delivers the results our patients want without putting their lives on hold. Whether you're targeting wrinkles, acne scars, or sun damage, fractional laser skin rejuvenation offers a balanced approach that respects both your skin goals and your busy lifestyle.
Choosing the Right Fractional Laser Technology
When it comes to fractional laser skin rejuvenation, not all technologies are created equal. The ideal treatment depends on your skin concerns, recovery tolerance, and skin type. At MD Body and Med Spa in Greenwood Village, CO, we offer several fractional laser options to address various skin concerns.
The main types of fractional lasers fall into two categories:
Fractional CO2 & Erbium Lasers
Fractional CO2 Lasers represent the gold standard for ablative fractional treatments. These devices use carbon dioxide laser energy to create controlled damage in the skin.
Key characteristics:
Deepest penetration (typically 750-2000 μm)
Excellent for moderate to severe wrinkles
Significant skin tightening effect
Effective for acne scars and deep textural issues
Recovery time: 5-7 days
Usually requires 1-2 treatments for optimal results
The CO2 fractional approach creates both heat and ablation. As one specialist explains, "The combination of heat-induced collagen remodeling and precise tissue removal makes fractional CO2 exceptionally effective for addressing multiple concerns simultaneously."
Popular fractional CO2 platforms include devices that offer different treatment modes:
DeepFX™: Delivers deeper, narrower columns for collagen stimulation
ActiveFX™: Creates a more superficial pattern for surface texture refinement
TotalFX™: Combines both approaches in a single session
Fractional Erbium:YAG Lasers provide a less aggressive ablative option with slightly faster healing.
Key characteristics:
Mid-depth penetration (typically 500-1500 μm)
More precise ablation with less heat
Good for moderate wrinkles and textural issues
Less downtime than CO2 (typically 3-5 days)
Better option for those with darker skin tones
Usually requires 1-3 treatments
"Erbium fractional lasers may work better and have fewer side effects for people of color compared to CO2 lasers," notes a prominent dermatologist. This is because they generate less heat, which reduces the risk of post-inflammatory hyperpigmentation.
Non-Ablative Fractional Platforms
Non-ablative fractional lasers heat the tissue without removing the surface layer, making them gentler options with less downtime.
1550 nm Fractional Lasers:
Target water in the skin to create controlled heating
Penetrate to mid-dermis (approximately 400-700 μm)
Excellent for improving texture and moderate scars
Minimal downtime (1-3 days of mild redness)
Requires 3-5 treatments spaced 2-4 weeks apart
Good option for busy individuals who can't afford downtime
1927 nm Thulium Fractional Lasers:
More superficial penetration focusing on the epidermis
Described by Dr. Green as a "magic eraser" for pigmentation
Exceptional for sun damage, melasma, and brown spots
Very minimal downtime (1-2 days)
Requires 3-5 treatments for optimal results
Safe for a wider range of skin types
Many modern devices, like the Fraxel Dual, combine multiple wavelengths (1550 nm and 1927 nm) to address both textural and pigmentation concerns in the same treatment.
"The ability to customize treatment depth and intensity is what makes fractional technology so versatile," explains one of our laser specialists at MD Body and Med Spa. "We can adjust settings based on your specific concerns, recovery tolerance, and skin type."
Here's a simplified comparison of the main fractional laser types:
Laser Type Penetration Depth Best For Recovery Time Sessions Needed Fractional CO2 Deep (750-2000 μm) Deep wrinkles, scars, laxity 5-7 days 1-2 Fractional Erbium Medium (500-1500 μm) Moderate wrinkles, texture 3-5 days 1-3 1550 nm Non-ablative Medium (400-700 μm) Texture, moderate scars 1-3 days 3-5 1927 nm Thulium Superficial (200-400 μm) Pigmentation, sun damage 1-2 days 3-5
Candidate Assessment & Treatment Journey
The path to refreshd skin through fractional laser skin rejuvenation begins well before you ever feel the first laser pulse. At MD Body and Med Spa, we take a thoughtful, comprehensive approach to ensure you're not just a good candidate, but that your treatment plan feels as unique as your skin concerns.
Who Is (and Isn't) a Good Candidate for Fractional Laser Skin Rejuvenation
Walking through our doors with fine lines, wrinkles, acne scars, or sun damage puts you in good company. These common concerns respond beautifully to fractional treatments, as do uneven skin texture, age spots, and mild skin laxity. Those with fair to medium-brown skin tones (Fitzpatrick types I-IV) typically see excellent results with minimal complications.
"I had struggled with acne scarring since my teens," shares Jennifer, one of our patients. "After three fractional laser sessions, the improvement wasn't just in my skin—it was in how I felt about myself. For the first time in years, I didn't feel the need to cover up with heavy makeup."
However, not everyone is an ideal candidate for these treatments. If you're dealing with active acne breakouts, infections, or have a history of keloid scarring, we'll likely recommend alternative approaches. Recent isotretinoin (Accutane) use, pregnancy, breastfeeding, or certain autoimmune conditions also signal caution.
For those with deeper skin tones (Fitzpatrick V-VI), we take extra precautions. While newer technologies have expanded treatment options, the risk of post-inflammatory hyperpigmentation remains higher. "For our patients with rich melanin," explains our lead aesthetician, "we often recommend a small test patch first, then monitor healing for several weeks before proceeding with full treatment."
Preparing for Your Session
The success of your fractional laser skin rejuvenation begins weeks before your appointment. Think of it as training for a marathon—proper preparation dramatically impacts your results and recovery.
Two to four weeks before your session, start being extra vigilant about sun protection. Apply broad-spectrum SPF 50 daily, even on cloudy days or when you're mostly indoors. This is also the time to press pause on retinoids, glycolic acids, and other potentially irritating skincare products.
If you smoke, try to stop—even temporarily. Smoking restricts blood flow to your skin, potentially compromising healing and results. "The patients who follow pre-treatment guidelines diligently," notes our skincare specialist, "consistently experience better outcomes and fewer complications."
As your appointment approaches (one week before), avoid blood-thinning medications and supplements (with your physician's approval, of course), skip any chemical peels or aggressive treatments, and maintain your strict sun protection regimen.
In the final 48 hours, you might begin antiviral medication if you have a history of cold sores, as the laser can trigger outbreaks in susceptible individuals. Skip that glass of wine and extra cup of coffee, as alcohol and excessive caffeine can increase swelling and redness post-treatment.

What Happens During Treatment Day
When your treatment day arrives, the experience at MD Body and Med Spa is designed to be comfortable and reassuring from start to finish.
After checking in, we'll thoroughly cleanse your skin and capture detailed "before" photos. For certain treatments, we might apply a blue dye to better visualize treatment areas. Then comes everyone's favorite part—comfort measures!
A topical anesthetic cream applied 45-60 minutes before treatment makes a world of difference. For more aggressive treatments, we might also offer oral pain or anti-anxiety medication. Our cold air cooling devices provide additional comfort during the procedure itself.
Once you're prepped and comfortable, protective eye shields are placed, and the treatment begins. The laser handpiece moves methodically across the treatment areas, typically covering 25-40% of your skin surface per pass. You'll feel heat and perhaps a snapping sensation—uncomfortable but manageable for most.
"It felt like hot rubber band snaps," describes Michael, a recent patient. "Not pleasant, but definitely tolerable. The numbing cream was a game-changer, and the cooling air felt wonderful throughout."
The actual treatment typically takes 20-45 minutes for a full face, though your entire appointment will last 1.5-2 hours including prep time. Immediately afterward, we'll remove any treatment dyes, apply cooling compresses, and review your post-care instructions before sending you home.
Aftercare & Recovery Roadmap
Your recovery journey is where patience truly pays dividends. The timeline varies based on laser type and treatment intensity, but here's what most patients experience:
In the first 24 hours, expect redness similar to a sunburn and some swelling (especially around the eyes). Apply cold compresses for 10-15 minutes hourly while awake, and sleep with your head liftd to reduce swelling. Keep your skin moist with the prescribed healing ointment or petroleum jelly, and avoid hot water, steam, and heat exposure.
During days 1-3, the initial redness begins to subside, though your skin may feel tight and dry. For ablative treatments, you might notice some pinpoint bleeding—completely normal. Begin gentle cleansing with lukewarm water and a mild cleanser, continue applying healing ointments, and maintain strict sun avoidance.
Around days 3-7 is when peeling or flaking typically begins. You might also notice bronze-colored skin—this is MEND (Microscopic Epidermal Necrotic Debris) formation and a natural part of the healing process. The golden rule here: do not pick or forcibly remove peeling skin! Let your body shed these layers naturally to avoid scarring or pigmentation issues.
By week 2 and beyond, most visible recovery signs should resolve, though some pinkness may persist for several weeks, especially after ablative treatments. You'll gradually transition back to your normal skincare routine and begin using SPF 30+ sunscreen daily.
"Recovery is where I see the biggest difference between patients who follow instructions and those who don't," emphasizes our lead aesthetician. "Those extra days of religious moisturizing and sun avoidance translate directly to better results and fewer complications."

Results, Maintenance, Costs & Safety
When it comes to refreshing your appearance, fractional laser skin rejuvenation delivers impressive results that continue to improve over time. At MD Body and Med Spa, we've seen countless patients delighted by their change – not just in their skin's appearance, but in their confidence as well.
Expected Results & Durability
The beauty of fractional laser skin rejuvenation lies in its progressive results. While you'll notice some improvements shortly after treatment, the real magic happens behind the scenes as your skin regenerates.
During the first 1-2 weeks after treatment, you'll begin to notice a fresher appearance once the initial redness subsides. Your skin tone will appear more even, and there's often an immediate improvement in superficial pigmentation that many patients find quite exciting.
"I was amazed at how quickly I started seeing changes," shares Jennifer, one of our patients. "After that initial week of healing, my skin had this glow that I hadn't seen in years. But that was just the beginning."
The real change unfolds over the next 1-3 months. This is when collagen remodeling kicks into high gear, gradually improving fine lines and refining skin texture. By months 3-6, you'll see the full results – smoother, tighter skin with significantly reduced wrinkles and scars.
What's particularly impressive about these results is their staying power. Unlike some treatments that offer only temporary improvements, the collagen stimulation from fractional laser skin rejuvenation can last for years. Of course, your skin continues to age naturally, which is why many patients maintain their results with:
A single touch-up treatment every 1-2 years
Daily sun protection (non-negotiable!)
Quality skincare products that support collagen
Healthy lifestyle choices that promote skin health
One 55-year-old patient with sun damage and acne scarring shared her experience: "The changes weren't dramatic overnight, but by three months, people kept asking what I'd done differently. They couldn't pinpoint exactly what had changed – they just thought I looked years younger and more refreshed."
Comparing Fractional Lasers to Peels, Microneedling & IPL
With so many skin rejuvenation options available today, it's natural to wonder how fractional laser skin rejuvenation stacks up against other popular treatments.
Chemical peels are fantastic for addressing surface concerns and mild pigmentation issues. They work by removing the outermost layers of skin to reveal fresher skin beneath. While effective, they simply can't match the depth of fractional lasers, which create controlled damage that extends into the dermis, triggering more substantial collagen remodeling. Peels typically require more frequent treatments but come with a lower price tag per session.
Microneedling creates tiny punctures in the skin to stimulate healing. It's excellent for improving texture and mild scarring, especially when combined with radiofrequency energy (RF microneedling). However, fractional lasers typically produce more dramatic results for deep wrinkles and significant textural concerns because they combine both physical and thermal injury. If you have darker skin, microneedling might be a safer option with less risk of pigmentation changes.
IPL (Intense Pulsed Light) treatments are wonderful for targeting pigmentation and vascular concerns like redness and visible blood vessels. They offer minimal downtime but focus primarily on color correction rather than texture improvement. Many patients benefit from combining IPL for pigmentation with fractional lasers for texture and deeper wrinkles.
"Each technology has its sweet spot," explains Dr. Emmick at MD Body and Med Spa. "For some patients, we actually recommend a combination approach – perhaps starting with IPL to address pigmentation, then following with fractional laser treatments to tackle texture and deeper concerns. It's all about customizing the approach to your specific needs."
Risks, Side Effects & Skin Tone Considerations
While fractional laser skin rejuvenation is generally safe when performed by qualified providers, it's important to have realistic expectations about the recovery process and potential risks.
Most patients experience expected side effects that are simply part of the healing process: redness and swelling that last 1-7 days (depending on treatment intensity), a warm sensation immediately after treatment, and dryness with peeling as your skin renews itself. You might also notice a temporary bronzing or darkening of treated areas – this is actually a good sign that the treatment is working!
Less commonly, some patients experience prolonged redness, temporary acne flares, or milia (tiny white bumps). These typically resolve with proper aftercare and time.
Rare complications can include post-inflammatory hyperpigmentation (darkening of the skin), hypopigmentation (lightening of the skin), infection, or scarring. These risks are significantly reduced when you choose an experienced provider like our team at MD Body and Med Spa, who carefully assess your skin and customize treatment parameters accordingly.
Your skin tone plays an important role in determining which fractional laser technology is safest for you. Traditionally, these treatments have been most suitable for lighter skin tones (Fitzpatrick types I-III), but advances in technology have expanded options for medium to darker skin tones:
Lighter skin tones (I-III) can generally receive any type of fractional laser treatment
Medium skin tones (IV) may require modified settings and careful assessment
Darker skin tones (V-VI) have a higher risk of pigmentation changes with certain lasers
For patients with darker skin, we may recommend specific technologies like non-ablative 1550 nm lasers at conservative settings or Nd:YAG-based fractional devices that are safer for melanin-rich skin. Scientific research on melanin-safe lasers continues to expand options for all skin tones.
"The key to safe treatment across all skin types is thorough assessment, appropriate device selection, and customized settings," explains our laser specialist. "At MD Body and Med Spa, we take the time to evaluate each patient's skin and develop a personalized approach that maximizes results while minimizing risks."
The investment for fractional laser skin rejuvenation averages around $1,255 per session, though this varies significantly based on the specific technology used and the treatment area. While this might seem substantial compared to some other treatments, many patients find the long-lasting results well worth the investment in their appearance and confidence.
Frequently Asked Questions about Fractional Laser Skin Rejuvenation
How Many Sessions Will I Need?
When patients ask me about fractional laser skin rejuvenation sessions, I always explain that it's not one-size-fits-all. Your personal journey depends on several important factors.
If you're considering an ablative fractional laser like CO2 or Erbium, you'll likely need just 1-2 treatments spaced several months apart. These more intensive treatments deliver dramatic results with fewer sessions, but require more downtime.
For gentler non-ablative options like the 1550 nm or 1927 nm wavelengths, plan for 3-5 treatments spaced about 2-4 weeks apart. These treatments build results gradually with minimal disruption to your daily life.
"I tell my patients to think of it like renovating a house," shares our treatment coordinator at MD Body and Med Spa. "Some concerns need a complete remodel—that's your ablative treatment—while others just need a series of smaller updates, which is more like the non-ablative approach."
Your personal treatment plan will consider your skin concerns, damage severity, age, and how your skin responds. During your consultation at our Greenwood Village location, we'll create a customized roadmap custom specifically to your needs.
Does the Procedure Hurt?
Pain is always a top concern for my patients considering fractional laser skin rejuvenation. While everyone's pain tolerance differs, most describe the sensation as uncomfortable rather than truly painful.
For non-ablative treatments, expect a warming sensation with mild "prickling" or "snapping" feelings. We apply a topical anesthetic cream before your treatment, which significantly reduces any discomfort. Our state-of-the-art cooling systems also provide continuous relief during the procedure, and most patients find any discomfort subsides immediately afterward.
Ablative treatments are more intense. Patients often describe a "hot pinprick" sensation. For these deeper treatments, we may recommend stronger topical anesthetics, nerve blocks, or even oral medication to ensure your comfort.
One of our regular patients, Jennifer, describes her experience perfectly: "With the numbing cream, it felt like someone was snapping a warm rubber band against my skin—definitely manageable. The cooling air was a lifesaver, and my provider checked in with me constantly to make sure I was comfortable."
At MD Body and Med Spa, your comfort is our priority. We've invested in advanced cooling technology and appropriate anesthesia options to make your treatment experience as pleasant as possible.
How Long Before I Can Wear Makeup Again?
This is one of the most common questions I hear from patients, especially those with busy social calendars. The timeline for resuming makeup after fractional laser skin rejuvenation varies based on your treatment type.
After non-ablative treatments, you can typically apply makeup within 24-48 hours. I strongly recommend starting with mineral-based products, which are gentler on healing skin. Make sure all your brushes and applicators are freshly cleaned to prevent any potential infection.
For ablative treatments, patience is key. You'll need to wait until your skin has fully re-epithelialized, which typically takes 5-7 days. Your provider will assess your skin during follow-up and give you the green light when it's safe.
"Green-tinted mineral foundations are wonderful for camouflaging that post-treatment redness," explains our aesthetician. "And I always remind patients to choose oil-free formulations to avoid clogging pores during this crucial healing phase."
Rushing back to makeup too soon can introduce bacteria, cause irritation, delay healing, and potentially lead to pigmentation issues. At MD Body and Med Spa, we provide detailed post-care instructions specifically custom to your treatment and skin condition, ensuring you know exactly when and how to safely reintroduce makeup into your routine.
Conclusion
Fractional laser skin rejuvenation represents one of the most significant breakthroughs in aesthetic medicine in recent decades. It's truly remarkable how these treatments create tiny zones of controlled injury while keeping surrounding tissue healthy, kickstarting your body's natural healing response and collagen production. The result? Smoother, more youthful skin without the lengthy recovery times of traditional laser treatments.
