Laser skin resurfacing uses focused light energy to remove or heat damaged skin so that smoother, healthier skin replaces it. It’s one of the most effective tools available for treating wrinkles, sun damage, scars, and uneven texture — and because “laser resurfacing” spans a wide range of devices and intensities, it can be tailored from a gentle refresh to a dramatic transformation.
How laser resurfacing works
Resurfacing lasers fall into two broad categories:
- Ablative lasers (CO2 and Erbium:YAG) vaporize the outermost layers of skin in a precise, controlled way. As the skin heals, it regenerates tighter, smoother, and more even. These produce the most dramatic results but require the most recovery.
- Non-ablative lasers (such as Fraxel and other fractional devices) pass through the surface to heat the deeper dermis, stimulating collagen without removing the top layer. Recovery is much faster, but it takes a series of sessions to match the impact of a single ablative treatment.
Most modern treatments are fractional, meaning the laser treats microscopic columns of skin while leaving surrounding tissue intact. This speeds healing and lowers risk while still driving strong collagen renewal.
What to expect during treatment
After numbing cream (and sometimes a local anesthetic for ablative treatments), the provider passes the laser over the target area. You’ll feel heat and a prickling or snapping sensation. Sessions range from 20 minutes to over an hour depending on the area and device.
Afterward, the skin is red, warm, and swollen. Non-ablative treatments may feel like a sunburn for a day or two; ablative treatments involve more pronounced redness, oozing, crusting, and peeling as the new skin forms over one to two weeks.
Results and timeline
- Non-ablative: Subtle improvement after each session, building over a series of 3–6 treatments.
- Ablative: A single session delivers significant change once healing completes, with continued improvement as collagen rebuilds over 3–6 months.
Either way, expect smoother texture, softened wrinkles, faded sun spots, and a more even, luminous tone.
Is laser resurfacing right for you?
Strong candidates have sun damage, fine lines, acne or surgical scars, or uneven tone and texture and want a real reset rather than a subtle tweak. Historically, traditional resurfacing lasers worked best on lighter skin tones, as deeper complexions carry a higher risk of pigment changes — though newer devices and careful settings have widened who can be treated. If you have a deeper skin tone, radiofrequency microneedling may be a safer route to similar texture and tightening goals.
Risks and side effects
Beyond the expected redness, swelling, and peeling, risks include prolonged redness, infection, changes in pigmentation (lighter or darker patches), and — rarely — scarring, particularly with aggressive ablative settings or improper aftercare. Strict sun avoidance and diligent post-treatment skincare are critical. An experienced, properly equipped provider is the most important safeguard.
What affects the cost
The price range for laser resurfacing is wide because it spans gentle non-ablative sessions to deep ablative CO2 treatments. Cost depends on the type of laser, the depth and intensity, the size of the treated area, the number of sessions, and your provider’s expertise. A full-face ablative treatment sits at the high end; a small non-ablative spot treatment is far less. Always confirm exactly which device and protocol your quote covers.
