A laser peel is a skin resurfacing procedure that uses concentrated light energy to remove damaged outer layers of skin, prompting your body to replace them with fresh, smoother tissue. The average cost is $1,829, and depending on the intensity of treatment, recovery ranges from a few days to several weeks. It’s one of the more effective options for reducing wrinkles, acne scars, sun damage, and uneven skin tone.
How a Laser Peel Works
The laser targets water molecules inside your skin cells. When the energy hits those molecules, it superheats them so rapidly that the cells vaporize in a controlled, precise peeling effect. This removes the outermost layer of skin (the epidermis) and, depending on the treatment depth, part of the layer beneath it (the dermis). The controlled injury triggers your body’s wound-healing response, which ramps up collagen production and causes the skin to tighten as it rebuilds.
Not all laser peels work this way. There are two broad categories:
- Ablative lasers physically remove skin tissue. These produce the most dramatic results but require more downtime.
- Non-ablative lasers leave the surface of your skin intact. They heat the deeper layers to stimulate collagen remodeling without vaporizing tissue, resulting in a gentler treatment with a shorter recovery period and more subtle results.
Types of Ablative Lasers
The two most common ablative lasers used for skin resurfacing are CO2 and erbium. Both target water in skin cells, but they interact with tissue differently. CO2 lasers use heat to rapidly tighten the skin with essentially no bleeding, making them the go-to choice for deeper wrinkles and more significant scarring. Erbium lasers are more precise in how they remove tissue, producing less surrounding heat damage. That precision typically means less post-procedure redness and a faster healing window, but it also means slightly less skin tightening compared to CO2.
Many modern laser peels use fractional technology, which treats only a fraction of the skin’s surface at a time, leaving tiny columns of untouched skin between the treated zones. Those intact columns act as a scaffold for faster healing. Fractional treatments offer a middle ground: meaningful results with significantly less downtime than a full-field ablative peel.
What a Laser Peel Treats
Laser peels are most commonly used for fine lines and wrinkles, sun damage and age spots, uneven skin texture, and acne scarring. For acne scars specifically, the procedure works best on superficial to medium-depth scars, including boxcar scars, shallow ice pick scars, superficial rolling scars, and raised (hypertrophic) scars. Studies on fractional CO2 lasers have shown roughly 50% improvement in moderate-to-severe acne scars.
Results tend to be most predictable in people with lighter skin tones (Fitzpatrick skin types I and II). That doesn’t mean darker skin tones can’t be treated, but the approach requires more caution, which is covered below.
What the Procedure Feels Like
Pain management depends on how deep the treatment goes. For lighter, non-ablative peels, a topical numbing cream applied 30 to 60 minutes beforehand is often enough, sometimes combined with cold air blown across the skin during treatment. The cold air acts as a form of local anesthesia and noticeably reduces discomfort.
Deeper ablative peels require more involved numbing. Your provider may use nerve blocks, which are injections along specific facial nerves to numb larger zones of the face, or a technique called tumescent anesthesia, where a diluted numbing solution is injected under the skin. For full-face deep resurfacing, some patients receive sedation so they’re relaxed or lightly asleep during the procedure. The treatment itself typically takes 30 minutes to two hours depending on the area being treated.
Recovery Week by Week
Recovery varies significantly based on treatment intensity. Here’s what to expect for a moderate fractional laser peel:
First 24 to 48 hours: Your skin will look red and feel warm, similar to a sunburn. Mild to moderate swelling is normal, especially around the eyes if the face was treated. The skin feels tight and sensitive.
Week 1: Light flaking and peeling typically begin around days 2 to 4 as the treated skin sheds. The skin underneath appears pink and may feel tight or itchy. Many people can return to normal activities within 48 to 72 hours for lighter treatments, though deeper peels may keep you home for a full week.
Week 2: Pinkness fades and skin texture becomes noticeably smoother. For pigmentation-focused treatments, you’ll see visible lightening of dark spots and more even tone. Most visible signs of healing are complete by this point for lighter treatments.
Residual pinkness or redness from a deep ablative peel can persist for several weeks to a few months. New collagen continues to form for three to six months after the procedure, so the full results take time to appear.
Aftercare Basics
There’s no single standard protocol for post-laser wound care, but keeping the skin moist is universally recommended. Healing ointments applied to the treated area reduce crusting and scabbing and help new skin cells migrate across the wound faster. In clinical comparisons, petroleum-based healing ointments outperformed lighter emulsion creams, producing less redness, less crusting, and faster skin closure in the first week.
Sun protection is critical during the healing period. New skin is extremely vulnerable to UV damage and pigmentation changes. You’ll need to avoid direct sun exposure and use a broad-spectrum sunscreen daily for several months. Your provider will also likely have you stop using any active skincare ingredients like retinoids or exfoliating acids until healing is complete.
Risks and Side Effects
The most common minor side effects are acne breakouts and small white bumps called milia, which usually resolve on their own. More serious but less frequent complications include:
- Scarring: Occurs in roughly 3.8% of cases, and when it does, infection is almost always the underlying cause.
- Herpes reactivation: If you carry the virus that causes cold sores, a laser peel can trigger an outbreak that spreads across the entire treated area. Providers typically prescribe antiviral medication before and after treatment to prevent this.
- Infection: Bacterial or fungal infection of the healing skin is uncommon with proper aftercare but can lead to scarring if untreated.
- Pigmentation changes: The skin may become darker (hyperpigmentation) or lighter (hypopigmentation) than surrounding areas, particularly in people with darker skin tones.
Skin Tone and Safety
Melanin, the pigment that gives skin its color, absorbs laser energy. The more melanin present, the more energy the skin’s surface absorbs, which increases the risk of burns, blistering, and pigmentation changes. For people with medium to dark skin tones (Fitzpatrick types IV through VI), this means standard laser settings can cause harm.
Safe treatment is still possible with specific adjustments. Providers use longer wavelength lasers that penetrate past the melanin-rich surface layer, lower energy settings, and reduced treatment density. Pre-treatment with a skin-lightening agent for several weeks before the procedure has been shown to reduce the risk of post-inflammatory darkening. Cooling the skin before and during treatment provides an additional layer of protection. If you have a darker skin tone, the most important step is finding a provider experienced in treating your specific complexion, as the margin for error is smaller.
Preparing for a Laser Peel
Preparation typically begins two to four weeks before your appointment. Depending on your skin type and concerns, your provider may start you on a retinoid cream to increase skin cell turnover, a lightening cream to reduce pigment activity, or a glycolic acid product to thin the outer skin layer. These pre-treatments help the laser penetrate more evenly and reduce the risk of uneven pigmentation afterward.
You’ll be asked to stop blood-thinning medications and supplements (like aspirin and fish oil) in the days before treatment to minimize bruising. If you have a history of cold sores, antiviral medication is started before the procedure. Smoking significantly impairs wound healing and increases complication risk, so most providers require you to stop well in advance.
