3–5 Sessions: Nurse Practitioner View on CoolPeel vs Fraxel
CoolPeel, an ablative fractional CO2 setting, generally works best for pronounced texture, deeper acne scarring, and visible skin laxity when you can accept several days of downtime. Fraxel, a non-ablative 1550nm fractional laser, generally suits milder texture, enlarged pores, and surface pigment with less recovery time and a gentler risk profile for many skin tones. The right pick still depends on your skin phototype, any history of pigment changes, and a proper medical assessment.
TL;DR:
CO2 ablative treatments like CoolPeel are more effective for deep scars and laxity but require longer recovery and carry higher PIH risks for darker skin types.
Fraxel non-ablative laser targets surface concerns such as mild texture, pores, and pigmentation, offering shorter downtime with less aggressive skin injury.
Study data shows similar improvement rates for both lasers on scars, with differences mainly in downtime and discomfort, depending on settings and skin type.
Proper treatment planning depends more on provider expertise, treatment protocols, and skin type than on device branding alone.
Conservative, staged treatments with strict aftercare significantly reduce risks of pigmentation issues and prolonged redness across all skin types.

How CoolPeel and Fraxel work and how mechanism shapes results
The two treatments sit on opposite sides of the laser resurfacing spectrum, and that difference drives almost everything else you need to know about them.
CoolPeel is a high-precision, short-dwell pulse setting (often called an H-pulse) used on CO2 laser platforms. It ablates, meaning it removes, a fractionated pattern of microscopic columns of skin. Because each pulse is so brief, less heat spreads into surrounding tissue than with older, more aggressive CO2 protocols, which is the whole premise behind the “cool” branding. Fraxel, by contrast, is non-ablative: it heats tissue in a fractionated pattern without vaporizing the surface, triggering a process called fractional photothermolysis. The skin’s outer layer stays largely intact, which is why recovery tends to be faster.
That mechanical gap explains the clinical split. Ablative CO2 removes tissue and triggers a stronger wound-healing cascade, which generally produces more collagen remodelling and tighter-looking skin. Non-ablative 1550nm devices work more gradually, with smaller improvements per session but a lower immediate burden on the skin.
In practice, this translates into different sweet spots:
Deeper acne scarring and marked textural irregularity tend to respond better to ablative CO2 approaches like CoolPeel, according to clinical guidance on carbon dioxide laser treatment.
Fine lines, early laxity, and overall skin tightening are areas where ablative CO2 usually shows a stronger effect per session than non-ablative devices.
Enlarged pores, mild texture, and superficial pigmentation or sun damage are typically well suited to Fraxel-style non-ablative fractional treatment, which the same clinical guidance describes as serving a more superficial resurfacing niche.
Patients wanting minimal visible downtime between sessions often lean non-ablative, since the skin surface isn’t breached.
Device settings matter as much as the category label. A CO2 platform run at an aggressive, high-fluence setting behaves very differently from the same platform run with a CoolPeel-style H-pulse protocol, which is one reason two people can describe “CO2 laser” experiences that sound nothing alike. Pulse duration, density, and depth are adjusted by the treating provider, and those choices directly affect both the strength of the result and how much downtime you’ll have.
What the clinical evidence actually shows
The research comparing ablative CO2 and non-ablative fractional lasers is more nuanced than most marketing pages suggest, and it’s worth knowing what the studies actually measured before you commit to either option.
A retrospective analysis of acne scars in ethnic skin compared non-ablative 1,550 nm and ablative fractional CO2 lasers directly. Among 82 patients, a similar proportion of patients achieved greater than 50% improvement with both the 1,550 nm device and CO2, a difference too small to call one modality clearly superior for scarring.
A 2024 meta-analysis pooling eight studies and 418 patients found CO2 fractional lasers had a higher effective rate for atrophic acne scars than Er:YAG fractional lasers (odds ratio 1.81) and shorter downtime (about 2.1 fewer days on average), but higher pain scores during treatment, according to the meta-analysis on fractional CO2 versus Er:YAG lasers. PIH differences between the two ablative devices weren’t statistically significant across the pooled data, which suggests that within ablative fractional lasers specifically, pigment risk has as much to do with technique and skin type as with the device itself.
A separate randomized controlled trial on striae distensae (stretch marks) split patients between non-ablative fractional and ablative CO2 fractional treatment on different body regions. Neither modality was statistically superior overall, though the CO2 arm showed greater elasticity gains alongside more prolonged erythema and perceived pain.
Most protocols across these studies used multiple sessions, typically three to five, spaced four to six weeks apart, with maintenance treatments considered later depending on how the skin ages and how much ongoing collagen support a patient wants. The biggest limitation across this evidence is heterogeneity: device models, pulse settings, and operator experience vary enough between studies that a single number rarely tells the whole story. A result reported for one CO2 platform at one setting doesn’t necessarily apply to a different device or a different provider’s protocol.
Safety profile and PIH risk by skin type
Both treatments carry a similar list of expected short-term effects: redness, mild swelling, crusting or flaking, and a sandpaper-like texture for several days. Less common but more serious risks include infection, prolonged redness, and scarring, and these risks scale with how aggressive the settings are and how well aftercare instructions are followed.
Redness and swelling are near-universal after CoolPeel and common, though usually milder, after Fraxel.
Crusting and visible peeling are typical with ablative CO2 and largely absent with non-ablative Fraxel treatment.
Infection and scarring are uncommon with either device but more associated with ablative resurfacing, particularly when aftercare is skipped.
Post-inflammatory hyperpigmentation is the risk that varies most by skin phototype and device choice.
Ablative CO2 generally carries a higher PIH risk in darker phototypes (Fitzpatrick IV through VI) than non-ablative fractional treatment, which is why many providers use prophylactic bleaching regimens and strict sun avoidance before and after treatment in these skin types, a practice supported by the comparative analysis of fractional lasers in ethnic skin. Pain also differs by modality. Fraxel is usually tolerable with topical numbing cream alone, while CoolPeel and other ablative CO2 settings often call for stronger topical anaesthesia or, for larger treatment areas, a local block.
Pro tip: Conservative settings and staged treatments, meaning smaller, more frequent sessions rather than one aggressive pass, tend to lower the chance of prolonged redness or pigment changes, especially on medium to deep skin tones.
What to expect before, during, and after treatment
Appointment length, downtime, and cost all follow a predictable pattern once you understand how the two treatments differ.
Appointment length: A CoolPeel session typically runs shorter than a full traditional CO2 resurfacing session because the pulses are brief, though exact timing depends on the treatment area. Fraxel sessions are generally similarly quick, often 30 to 45 minutes once numbing has taken effect.
Immediate appearance: Skin looks pink to red with a frosted or gridded texture right after CoolPeel, and mildly flushed with pinpoint bleeding points possible after Fraxel.
Downtime: CoolPeel-style ablative treatment usually involves visible redness, peeling, and some crusting for roughly three to seven days before makeup can comfortably cover it. Fraxel’s non-ablative approach typically allows a return to makeup and normal activity within one to three days.
Aftercare: Both treatments require diligent SPF use, gentle cleansing, and avoidance of active ingredients like retinoids until the skin has fully healed. Our pre- and post-procedure guidelines outline the specific steps that reduce infection and pigment risk.
Follow-up and cost drivers: Pricing for either treatment depends on the device used, the provider’s training, the size of the treatment area, and how many sessions your goals require, which is why quotes vary so much between clinics.
How to choose: a decision checklist
Turning all of this into a decision comes down to matching the treatment to your concern, your skin, and your tolerance for downtime.
Identify your primary concern first: deeper scarring and laxity point toward ablative CO2, while pores, tone, and mild texture point toward non-ablative Fraxel.
Know your Fitzpatrick skin type: darker phototypes generally warrant more caution with ablative settings and a documented pre-treatment pigment protocol.
Be honest about downtime tolerance: if you can’t take a week of visible healing, non-ablative treatment is the more realistic option.
Disclose any history of PIH or melasma, since this changes both the device choice and the settings a provider should use.
Set a realistic budget that accounts for multiple sessions rather than assuming one treatment will finish the job.
Before booking, ask your provider which specific device and model they use, what settings they plan for your skin type, whether a nurse practitioner or physician supervises treatment, how many sessions they expect you’ll need, and whether they can show relevant before-and-after examples. Be cautious of any clinic that skips a real skin assessment, offers no written pre- or post-care protocol, or promises dramatic results with zero downtime.
A nurse practitioner’s perspective on matching treatment to skin
Choosing between CoolPeel and Fraxel starts with an honest look at scarring depth, skin phototype, and what a patient is actually trying to fix, not with which device sounds more advanced. At our clinic, a Nurse Practitioner-led assessment precedes any recommendation for TETRA PRO CO2 or a non-ablative route, because the same “CO2 laser” label can mean very different settings depending on the goal.
For patients with deeper acne scarring and tolerance for downtime, we often stage CO2 sessions at conservative settings rather than pushing for maximum effect in one pass, particularly on medium to deep skin tones where pigment risk is higher. For patients focused on pore size, tone, or early texture changes, a gentler non-ablative approach, sometimes combined with complementary treatments like microneedling, can achieve meaningful improvement with far less recovery. Every plan follows our pre- and post-procedure guidelines to manage pigment risk and support healing.
The editorial take: don’t let the device name decide for you
The most overrated part of this comparison is the idea that “CoolPeel” and “Fraxel” are two fixed, interchangeable products you can rank against each other in the abstract. They’re not. CoolPeel is a specific pulse strategy on a CO2 platform, and how aggressively it’s dialled in changes your downtime and risk as much as switching devices entirely would.
What the evidence actually supports is narrower and less exciting than most comparison articles promise: both modalities work reasonably well for scarring and texture, the gap between them is often smaller than marketing suggests, and the variable that matters most isn’t the brand name on the machine. It’s your skin phototype, your provider’s settings, and whether prophylactic pigment protocols are actually followed.
If you take one thing from this, prioritize the provider’s assessment and aftercare protocol over the device name. A well-run Fraxel session from a careful provider will beat a poorly staged, overly aggressive CO2 session every time, regardless of which one sounds more advanced on a treatment menu.

FAQ
What laser does Kim Kardashian use?
Celebrity laser routines aren’t independently verified or publicly documented in clinical sources, so we can’t confirm a specific device tied to any public figure. What’s documented instead is how ablative CO2 and non-ablative fractional lasers compare for common concerns like scarring, texture, and pigment, which matters more for your own decision than any celebrity’s reported routine.
Is CoolPeel worth the money?
CoolPeel tends to be worth it for people with deeper texture or scarring concerns who can tolerate several days of downtime, since ablative CO2 settings generally produce stronger collagen remodelling per session than non-ablative options. For milder concerns or a tighter downtime window, a non-ablative treatment like Fraxel may deliver comparable satisfaction with less recovery, so value depends on matching the treatment to the concern rather than the treatment alone.
Is there a better treatment than Fraxel?
“Better” depends entirely on the concern. Evidence comparing ablative CO2 and non-ablative 1,550 nm fractional lasers for acne scarring found both achieved similar improvement rates, with ablative CO2 often preferred for deeper scarring and non-ablative treatment preferred when downtime or pigment risk is a bigger concern.
How long do CoolPeel results last?
Results from ablative CO2 treatments like CoolPeel typically build over the weeks following treatment as collagen remodels, with visible improvement often continuing for a few months. Because skin continues to age, most people benefit from periodic maintenance sessions rather than expecting a single treatment to hold indefinitely.
