Acne scars are not all the same, and neither are the devices used to treat them. If you have researched Fraxel, CO2, or Pico, you have likely seen confident claims, mixed reviews, and before-and-afters that look too good to be typical. Choosing wisely starts with understanding your scar type, your skin tone, and your tolerance for downtime. It also requires a realistic goal, which is improvement, not 100% removal.
At Laser Skin Center Medical Spa on Newbury Street, our physicians oversee acne scar protocols that combine FDA-cleared picosecond laser technology with RF microneedling and, in select cases, TIXEL. We intentionally do not offer every branded fractional laser on the market. Instead, we focus on combinations that balance collagen remodeling with pigment safety, especially for diverse skin tones that are more prone to post-inflammatory hyperpigmentation.
This guide explains how Fraxel, CO2, and Pico compare, when a combination approach makes sense, and how to plan around Boston’s seasons so you can protect your results.
First, know your scars
Acne scars fall into two broad categories that behave differently.
- Atrophic scars are depressions in the skin. Ice pick scars are narrow and deep; boxcar scars have sharp edges; rolling scars are wider and softer. These usually respond to collagen-inducing treatments like RF microneedling, Pico for remodeling and pigment, and fractional resurfacing. Deep ice pick scars may need focal treatments such as TCA cross or surgical techniques performed by a physician.
- Hypertrophic or keloid scars are raised due to excess collagen. These are managed with different strategies, often including corticosteroid injections or vascular lasers to calm redness. Aggressive heat or ablative resurfacing can aggravate them if not carefully selected.
Accurate classification matters because the right device, depth, and energy are not the same for each scar type. Our consultations map scar patterns and skin tone to a staged plan rather than a one-device promise.
Fraxel vs CO2 vs Pico, explained simply
These platforms remodel collagen in different ways.
- Fraxel describes fractional lasers that create microscopic columns in the skin, leaving bridges of intact tissue to speed healing. There are non-ablative versions with quieter downtime and ablative versions with more dramatic resurfacing and more recovery.
- CO2 lasers vaporize tissue in tiny columns and generate strong thermal coagulation. They can deliver significant improvement for texture and wrinkles, but recovery and pigment risk are higher, especially on darker or recently tanned skin.
- Pico lasers deliver picosecond pulses that shatter pigment and trigger collagen via a photo-mechanical effect with minimal heat. They are useful for acne marks, mixed discoloration, and mild to moderate textural change with short downtime.
In practice, many patients benefit from a sequence. Pico can safely reduce brown and red marks while starting collagen remodeling. RF microneedling can then address depth and tethering in rolling and boxcar scars without injuring the surface. TIXEL may be layered for fine texture when appropriate. Fractional CO2 can be effective for select fair skin types with significant texture, but we reserve more ablative paths for cases where the risk-benefit is clear under physician guidance.
Skin tone safety and downtime
Pigment safety drives device choice. Non-ablative fractional and Pico treatments are typically safer across a wide range of Fitzpatrick skin types when performed with conservative, physician-developed settings. RF microneedling bypasses epidermal pigment and directly stimulates the dermis, which is why it is a mainstay in atrophic scar protocols for diverse tones.
Downtime varies by intensity and stacking. Pico sessions often have one to three days of mild redness. RF microneedling recovery is usually two to five days of redness and pinpoint flaking. TIXEL or fractional resurfacing can add several days of social downtime depending on the density and depth used. We tailor recovery to your calendar and season.

What improvement looks like
Fractional laser does not erase acne scars. Any platform that claims 100% removal is setting you up for disappointment. Most patients see gradual, cumulative improvement across a series. Typical goals include softer edges on boxcar scars, a smoother transition around rolling scars, and a more even tone as marks fade. Deep ice pick scars often improve with targeted adjuncts rather than global passes alone.
Expectations also depend on age of the scars, skin biology, and adherence to aftercare. Sunscreen is non-negotiable. Picking or reopening lesions restarts inflammation that can create new marks.
Our physician-guided approach in Boston
We use FDA-cleared picosecond technology, RF microneedling, and selective TIXEL in physician-developed combinations. This lets us modulate energy in the dermis while protecting the epidermis. It also means we can stage care safely for darker and tanned skin where ablative heat has higher risk. If you are comparing clinics, prioritize physician oversight, device range, and a track record of treating all skin tones with conservative settings that still move the needle.

Summer timing and sun safety
Boston summers are beautiful and bright. UV exposure increases pigment risk after any resurfacing. We often plan pigment-led Pico sessions earlier in the season with strict daily SPF 30 to 50, hats, and shade. We schedule higher-intensity resurfacing or RF microneedling blocks in late summer into fall when UV index declines, or we add more buffer days and sunscreen counseling if your schedule requires summer sessions. Consistency with sun protection preserves your gains better than any device choice.
Cost, insurance, and how to plan a series
Pricing varies by modality, treatment area, intensity, and the number of sessions. Most patients budget for a series rather than a single visit. Because individual factors drive cost, we provide a clear estimate after consultation. Insurance typically does not cover acne scar revision since it is considered cosmetic. If a raised scar is symptomatic, your physician can advise on medical treatment pathways, but cosmetic resurfacing is almost always out-of-pocket.
When we do not recommend aggressive lasers
If you have active acne cysts, uncontrolled melasma, a history of keloids, or a recent suntan, we may delay ablative resurfacing or choose lower-heat options first. Stabilizing inflammation and pigment response creates a safer runway for textural work. Melasma in particular prefers gentle, pigment-safe approaches. If that is your main concern, you can read more about how we approach pigmentation in our page on melasma treatment in Boston.
Quick FAQ
- Does fractional laser get rid of acne scars? Fractional laser can significantly soften atrophic scars over a series, but it does not erase them. Expect improvement, not perfection.
- Is Fraxel or CO2 better for acne scars? It depends on scar type, skin tone, and downtime tolerance. CO2 can be powerful for fair skin with pronounced texture, while non-ablative fractional options are gentler. We often prefer Pico plus RF microneedling for diverse tones to balance results and safety.
- Can you 100% remove acne scars? No. Scars can be improved, often dramatically in the best candidates, but complete removal is not realistic.
- How much does it cost to fix acne scarring? Costs vary by device and number of sessions. A consultation is the only accurate way to estimate a personalized plan.
- What actually fades acne scars? Collagen remodeling from RF microneedling, Pico-induced remodeling, fractional resurfacing, and targeted focal techniques for ice pick scars. Consistent sun protection prevents new discoloration and protects progress.
- Will insurance pay for acne scar removal? Cosmetic scar revision is typically not covered. Your clinician can advise on exceptions for symptomatic raised scars, but aesthetic resurfacing is usually self-pay.
How to take the next step

Summary: Not every scar needs the same device. Atrophic and hypertrophic scars respond differently, skin tone safety comes first, and improvement builds across a series. In Boston, a thoughtful combination such as Pico plus RF microneedling, with selective TIXEL and careful sun timing, often delivers steady, realistic gains with lower risk. A personalized, physician-guided plan is the wisest choice.
