What You Need To Know About Ablative vs Non Ablative Laser Devices
What Are Ablative Lasers?
Ablative lasers are like the heavyweights in the world of skin treatments. These lasers work by actually removing the top layers of your skin. It sounds intense, and honestly, it kind of is, but that’s exactly why they’re so effective. The idea is to resurface the skin by vaporizing the outer layers where most of the damage, like wrinkles and scars, tends to live. Once those damaged layers are gone, your body starts working to heal and rebuild fresh, smoother skin. Think of it as giving your skin a total reset.
Types of Ablative Lasers (CO2, Erbium)
When we talk about ablative lasers, two big names come to mind: CO2 and Erbium. They both do essentially the same thing—removing layers of skin—but with some differences.
CO2 lasers (Acupulse, Mixto Pro, ActiveFX, DeepFX) are the most aggressive of the two. They dig a little deeper and are often the go-to for deep wrinkles, advanced sun damage, and significant scars. If you’ve got deep-set wrinkles or severe scarring, a CO2 laser could be the best option.
On the other hand, Erbium lasers are like the gentler sibling (Profractional, Contour TRL, Fotona) While still ablative, Erbium has a higher coefficient for water absorption so it doesn’t heat up deeper layers like the CO2 which causes months of stubborn redness.
This makes the Erbium which for ideal for treating fine lines, mild scars, and more superficial skin issues like pigmentation. They’re a bit more forgiving in terms of downtime, too, but we’ll get to that in a second.
Common Skin Concerns Ablative Lasers Treat
Well, if you’ve been battling deep wrinkles (you know, the ones that creams and serums just can’t touch), acne scars, or those stubborn age spots, ablative lasers are worth considering. They’re also fantastic for people dealing with significant sun damage, as they can peel away those discolored, rough patches and reveal healthier skin underneath. I’ve seen people in their 50s and 60s walk away looking at least a decade younger after a well-done ablative laser treatment check out my article on MicroLaserPeel. But, fair warning, the process isn’t exactly a walk in the park.

What Are Non-Ablative Lasers?
Non-ablative lasers are kind of like the friendly neighbors in the laser treatment world. While ablative lasers go all-in, removing layers of skin for a major overhaul, non-ablative lasers take a more subtle approach. They work beneath the surface of the skin, targeting the inner layers while leaving the top layer intact. I like to think of them as a more gentle option for people who want to see real skin improvements but without the big downtime. The idea is to trigger your skin’s natural healing response, stimulating collagen production from within.
Types of Non-Ablative Lasers
Now, let’s dive into some of the main types. Two popular non-ablative lasers are Nd Yag and fractional lasers.
Nd Yag (Aerolase, Laser Genesis) is known for its versatility—it can handle a variety of skin concerns, like reducing redness, targeting minor pigmentation, and even helping with mild acne scars. It’s also safe for a wider range of skin tones, which is a big plus if you’re looking for a less risky treatment option.
Then there’s the fractional non-ablative laser, which is like the overachiever of non-ablative treatments (Fraxel Dual, LaseMD, Moxi, Clear & Brilliant). It delivers laser energy in small, focused beams, meaning only a fraction of the skin is treated at once. This allows for more targeted improvements in skin texture, fine lines, and early signs of aging. You’ll often hear it called a “fractional resurfacing laser” because it’s designed to boost your skin’s texture without the full-on peel that comes with ablative lasers.
Skin Conditions Treated by Non-Ablative Lasers
So, what exactly can non-ablative lasers fix? The list is longer than you’d think. They’re perfect for treating mild acne scars, early signs of aging like fine lines and wrinkles, and hyperpigmentation issues like sunspots or melasma. I remember the first time I tried a fractional non-ablative laser—it was after a summer of not being as diligent with sunscreen as I should’ve been. I had all these little brown spots starting to pop up, and the fractional laser did wonders in evening out my skin tone.
But, I’ll be honest—if you’re dealing with deep wrinkles or severe scars, non-ablative lasers might not pack enough punch. They’re more like maintenance treatments that keep your skin looking good over time. If you’re consistent, you’ll start noticing your skin getting smoother and more even. It’s like adding another layer of “wow” to your skincare routine without totally disrupting your life.

Ablative vs Non-Ablative Lasers: Key Differences
If you’re weighing your options between ablative vs non-ablative lasers, you’re probably trying to figure out which one will give you the best results with the least hassle. Like yourself, most people have this same question and the answer is actually pretty simple. Let’s break it all down, from how deep they go to how much they’ll lighten your wallet.
Depth of Skin Penetration and How It Affects Results
Ablative lasers work like a bulldozer, stripping away the outer layers of skin to address issues right at the surface. This makes them fantastic for tackling deep wrinkles, stubborn acne scars, and significant pigmentation. You’re getting a full-on skin reset here, which is why the results can be so dramatic.
Non-ablative lasers, on the other hand, are more like a gentle gardener—they focus on heating up the deeper layers of skin without removing any skin tissue. They stimulate collagen production from the inside out. So, while they may not be as intense as ablative lasers, they’re ideal for building long-term improvements in skin texture, tone, and even mild scarring. It’s slower, but more of a “build as you go” type of transformation.
Treatment Frequency and Expected Results Over Time
Here’s where things get interesting: with ablative lasers, you often only need one or two treatments to see significant changes. It’s a bigger hit upfront, but the results can last for years if you take good care of your skin.
Think of it like going to the gym once a month and coming out with abs (I wish). But seriously, the intensity of ablative lasers means you get more bang for your buck with fewer sessions. I’ve personally witnessed a patient that one single Contour TRL laser treatment that lasted over 10 years.
Non-ablative lasers, meanwhile, require a series of treatments—usually about 3 to 6 sessions spaced a few weeks apart. It’s more of a low and slow approach (don’t expect miracles), but it can be great for maintenance.
I once did a series of Moxi’s to maintain my Halo and it worked like a charm! While the results took a few months to fully develop, my skin looked smoother and more even overall. It just takes a bit of patience!
Downtime and Recovery: What to Expect from Both Types
Non-ablative lasers are much kinder in the downtime department. You might have a bit of redness or swelling (as shown above), but it usually clears up within a day to 5 days. You can generally go back to work or even hit a low-key event without too much worry. If you’re busy juggling work, kids, and life (I totally get it), non-ablative lasers are definitely more convenient in this aspect. Also, makeup can be applied right after treatment.
Ablative lasers can be a bit of a beast. After a treatment, expect at least a week of redness, peeling, and some serious downtime. You might feel like you need to lay low for a bit, and trust me, you’ll want to. Your skin is vulnerable during recovery, and you need to stay out of the sun and pamper your face to avoid complications.
Risks and Potential Side Effects
Non-ablative lasers are generally safer because they don’t break the skin’s surface. However, they’re not without risks—pigment changes, minor swelling, or even infection can occur. Additionally, I’ve even seen cold sore breakout occur with a mild laser treatment. Best to be preventative and ask your provider for an antiviral and proper skin products.
Both types of lasers come with their own set of risks, but ablative lasers tend to carry more of them. Because they remove the outer layer of skin, there’s a higher chance of complications like infection, prolonged redness, or even scarring if you don’t follow the aftercare instructions closely. It’s crucial to work with an experienced professional to minimize these risks. All in all, yes there are more potential risks, but nowadays we have ways to mitigate any/all of these side effects as long as you choose your provider wisely.
Cost Comparison: Which One Is More Expensive and Why
Alright, let’s talk money. Ablative lasers are often more expensive per session because they deliver dramatic results in fewer treatments. You might be looking at $2,000 to $5,000 per session, depending on the area and provider. It’s a big upfront cost, but you’re getting a one-and-done (or maybe two-and-done) deal that can last for years.
Non-ablative lasers are usually less expensive per session, ranging from $500 to $2,000, but since you’ll need multiple treatments, the costs can add up over time. The upside is that it’s more budget-friendly in the short term, and you can space out the payments since you’ll be going back for follow-ups.

Which Laser Intensity Is Right for You?
Ablative vs non-ablative lasers. Each one has its pros and cons, and the best choice really depends on a few factors. Trust me, I’ve been down this road before, and I wish someone had broken it down clearly from the start. Let’s look at what makes these treatments suitable for different skin types, personal factors to consider, and even the possibility of using both for a better outcome.
Skin Types That Benefit from Ablative vs Non-Ablative Lasers
Non-ablative lasers, on the other hand, tend to be more forgiving across a wider range of skin tones. They’re often a safer bet for medium to dark skin tones since they don’t remove the outer layer of the skin.
Generally speaking, darker skin tones are more prone to acne scarring or discoloration concerns over wrinkles. Non ablative lasers target just that. So, it is a perfect marriage.
Ablative lasers are the gold standard for targeting wrinkles, fine lines and skin laxity. Historically, ideal candidates were lighter skin tones (Fitzpatrick skin types I-III). That’s because deeper skin tones were at higher risk for complications like post-inflammatory hyperpigmentation (PIH). Now, we have a multitude of interventions to prevent or treat PIH. As a provider myself, I have treated skin types I-IV with ablative lasers safely and effectively.
Factors to Consider (Age, Skin Concerns, Downtime Tolerance)
Let’s get real here. Your choice between these lasers will depend a lot on what you want to achieve and how much downtime you can handle.
If you’re looking to treat fine lines, mild pigmentation, or just want an overall boost in skin texture, non-ablative lasers are a great option. They’re also more suitable for people who can’t afford the downtime. I get it; life gets busy, and not everyone can take a week off just to heal. Non-ablative treatments offer more subtle improvements over time and can easily be squeezed into a lunch break (well, almost).
But if you’re dealing with deep wrinkles, severe acne scars, or significant sun damage and you’re okay with taking a week or two off for recovery, then an ablative laser could be a game-changer. The results can be dramatic, like shaving years off your skin.
Your age also plays a role. Younger skin aging includes superficial eyelid wrinkles, sun damage, rosacea and acne making non-ablative lasers a good fit for maintenance and early intervention.
Older skin may need the deeper penetration of an ablative laser to tackle more entrenched wrinkles, skin laxity and severe sun damage.
Combining Treatments: Can You Use Both for Better Results?
Here’s a little insider secret: sometimes, you don’t have to choose just one. Combining ablative and non-ablative treatments can actually yield better, more comprehensive results. You might start with an ablative laser to tackle major concerns like deep scars or wrinkles, then follow up with non-ablative treatments for maintenance. It’s like using a sledgehammer to knock down the wall and then a fine chisel to smooth things out.
I’ve seen people get fantastic results by layering treatments this way, but again, it’s essential to work closely with a pro. Combining treatments can amplify the benefits, but it also increases the risk of side effects if not done correctly. You’ll want a treatment plan that’s tailored specifically to your skin’s needs and your schedule.

Real-Life Results and What to Expect
So, let’s get to the good stuff—real-life results. You’ve probably read all the technical details and weighed the pros and cons of ablative and non-ablative lasers, but what really matters are the outcomes people experience in everyday life. And yes, I’ve seen the impact of these treatments firsthand. Whether it’s for reducing wrinkles, fading acne scars, or just getting a general skin refresh, the results can be life-changing. But they can also vary a lot depending on factors like skin type, age, and commitment to maintenance.
Case Studies: Results of Patients Using Ablative and Non-Ablative Lasers
Let’s look at some hypothetical case studies to better understand what results you can expect.
Case Study 2: Non-Ablative Laser for Acne Scars
Below is me. I had one single non ablative laser treatment (moxi) because I couldn’t schedule the downtime of an ablative laser. There is noticeable brightening and my sun spots literally fell off. I try to get one every 3 months as part of my maintenance skin program. Plus, the non-ablative laser stimulated my collagen over time, so I continue to see improvements for months afterward.

Case Study 1: Ablative Laser for cobblestone texture
Meet Linda, a 62-year-old woman who struggled with a cobblestone-like texture around her mouth (think the orange peel texture). She decided to try an Erbium ablative laser (Contour TRL). The first week after treatment was tough—redness, swelling, and lots of pin point bleeding.
But by the end of week two, the results were undeniable. The deeper lines were noticeably smoother, and her skin had a more youthful texture overall. The doctor warned her that results like this could last 5 to 10 years with good skincare and sun protection, and regular touch-ups might be needed.

Conclusion:
Both ablative vs non-ablative lasers can offer incredible results for your skin, but the right choice depends on your unique concerns and goals. While ablative lasers may be more aggressive with longer recovery times, they can deliver dramatic, lasting improvements for deeper skin issues. On the other hand, non-ablative lasers offer a gentler, no-downtime approach, perfect for those with less severe concerns. Consult with a professional to find out which option is best for you!
