Fractional resurfacing lasers are the gold standard for treating sun-damaged skin, according to the American Academy of Dermatology. But “best” depends entirely on what kind of sun damage you’re dealing with, how much downtime you can tolerate, and your skin tone. Someone with deep wrinkles and rough texture needs a different laser than someone whose main concern is brown spots scattered across their cheeks. Here’s how the major options compare so you can have an informed conversation with a dermatologist.
How Lasers Fix Sun Damage
All skin lasers work by creating controlled injury. Your body responds to that injury by producing fresh collagen and replacing damaged cells with new ones. The differences between laser types come down to how deep that injury goes, whether the outer layer of skin is removed or left intact, and what specific targets (pigment, blood vessels, water in skin cells) the laser energy is tuned to hit.
Sun damage shows up in several ways: fine lines and wrinkles, rough or leathery texture, brown spots and uneven tone, broken blood vessels, and precancerous rough patches called actinic keratoses. No single laser addresses all of these equally well, which is why dermatologists often recommend combining treatments or choosing a laser based on your most bothersome concern.
Ablative Lasers: The Most Dramatic Results
Ablative lasers vaporize the outer layer of skin by superheating water molecules in your cells. As the skin heals, it contracts and tightens while producing new collagen in the deeper layers. The two main types are CO2 (carbon dioxide) and erbium:YAG lasers, and both are available in fractional versions that treat a grid of tiny columns rather than the entire surface. Fractional delivery leaves islands of untouched skin between treatment zones, which speeds healing considerably.
For severe sun damage with deep wrinkles, significant texture changes, and mottled pigmentation, ablative fractional lasers remain the most effective single treatment. A clinical comparison of CO2 laser versus a newer hybrid system found that CO2 produced better scores for fine lines, tactile roughness, and mottled pigmentation alike. The trade-off is real, though: healing times and complication rates were also higher with CO2. Risks include scarring, prolonged redness, infection, and skin discoloration, particularly in darker skin tones.
Most people need only one ablative treatment to see significant improvement, and results can last for years. If you opt for a fractional ablative approach, you may need two to four sessions spaced over weeks or months for the best outcome.
What Ablative Recovery Looks Like
The first day after a CO2 or similar ablative laser treatment, your skin feels like a sunburn: red, swollen, warm, possibly with mild oozing. By days two and three, the treated skin dries, crusts, and begins to scab. Days four and five bring peeling as the damaged outer layer sloughs off, revealing pink new skin underneath.
By the end of the first week, most peeling has stopped and the skin looks noticeably smoother, though still pink or red. That pinkness typically fades over weeks two and three. By week four, most people can appreciate the full results: smoother, more even-toned, rejuvenated skin. Plan for at least a week of social downtime, and expect some residual pinkness for two to three weeks after that.
Non-Ablative Lasers: Less Downtime, Gentler Results
Non-ablative lasers leave the outer skin layer intact while heating the deeper dermal layers to stimulate collagen remodeling. Because the surface isn’t broken, recovery is dramatically easier. Many people return to normal activities the same day or the next, with only mild redness and swelling.
The catch is that results are more moderate. Non-ablative treatments work well for mild sun damage, early fine lines, and subtle texture improvement, but they won’t deliver the same transformation as ablative resurfacing for someone with years of accumulated photodamage. You’ll typically need two to four sessions to see noticeable changes, and research suggests wrinkle improvement with non-ablative lasers is more limited than with ablative ones.
For patients who want some rejuvenation but can’t afford a week of recovery, non-ablative fractional lasers hit a practical sweet spot. They’re also a safer starting point for darker skin tones, where the risk of post-treatment discoloration is higher with more aggressive approaches.
Hybrid Lasers: Splitting the Difference
Hybrid fractional lasers combine an ablative wavelength with a non-ablative wavelength in the same device, delivering both simultaneously. A common configuration pairs a 2940-nm erbium laser (ablative) with a 1470-nm wavelength (non-ablative). The idea is to get closer to ablative-level results while keeping downtime and side effects closer to the non-ablative range.
Clinical data supports this middle-ground approach. In a study comparing hybrid laser treatment to fractional CO2, both technologies produced significant improvement in fine lines, roughness, and pigmentation. The CO2 laser scored better on every clinical measure, but patients reported greater overall satisfaction with the hybrid laser. Faster healing and less discomfort outweighed the slightly lesser improvement for most people in the study. If you want meaningful results but a week of downtime isn’t realistic, hybrid systems are worth discussing with your provider.
IPL for Sun Spots and Redness
Intense pulsed light (IPL) isn’t technically a laser. It uses broad-spectrum light to target pigment and blood vessels simultaneously, making it particularly effective for the classic signs of sun damage that are color-based: brown spots, redness, and broken capillaries. IPL can treat a large area of skin in a single pulse, which makes sessions fast and relatively comfortable.
IPL works best for surface-level discoloration rather than textural damage or wrinkles. If your main complaint is a mottled, sun-spotted complexion rather than lines and roughness, IPL may be all you need. Sessions are quick with minimal downtime. Brown spots typically darken and flake off over the following week. Most people benefit from a series of treatments spaced a few weeks apart.
One important caveat: IPL targets pigment broadly, which makes it riskier for darker skin tones where the device can’t easily distinguish sun spots from your natural melanin. It’s best suited for lighter skin types.
Picosecond Lasers for Stubborn Pigment
Picosecond lasers fire in ultra-short bursts (trillionths of a second), shattering pigment through a photoacoustic, pressure-wave effect rather than the heat-based destruction that traditional lasers use. This means they can break up pigment more efficiently while causing less thermal damage to surrounding tissue.
For sun-induced brown spots and melasma that hasn’t responded well to other treatments, picosecond lasers offer a useful option. Studies on the 755-nm picosecond laser show significant pigment clearance, and when compared to fractional CO2 for certain indications, picosecond lasers produce similar effectiveness with a lower incidence of post-inflammatory hyperpigmentation. That lower darkening risk makes them a particularly appealing choice for medium and darker skin tones.
Skin Tone Matters for Laser Selection
Melanin in your skin absorbs laser energy. The more melanin you have, the more energy gets absorbed by your normal skin rather than the intended target, increasing the risk of burns and post-treatment darkening. This isn’t a minor consideration. For people with medium to dark skin (Fitzpatrick types IV through VI), laser selection and settings need to be adjusted carefully.
Longer-wavelength lasers penetrate deeper and bypass more of the melanin-rich outer skin, making them safer for darker complexions. Lower energy settings and lower treatment densities also reduce risk. Your provider may recommend pre-treatment with a skin-lightening cream for several weeks before the procedure, and epidermal cooling during treatment helps prevent pigmentary complications. Picosecond lasers and certain non-ablative fractional lasers tend to be the safest options for darker skin, while aggressive ablative treatments and IPL carry the highest risk of unwanted color changes.
Preparing Your Skin Before Treatment
Most dermatologists prescribe a pre-treatment regimen that starts several weeks before your laser appointment. A typical preparation plan includes a topical retinoid to thin the outer skin layer and speed cell turnover, a skin-lightening agent to reduce melanin activity and lower the risk of post-treatment darkening, and oral antiviral medication starting just before the procedure to prevent cold sore reactivation (which laser treatment can trigger even if you haven’t had an outbreak in years). Oral antibiotics may also be prescribed as a preventive measure against infection.
Good sun protection in the weeks before and after treatment is essential. Fresh sun exposure before a laser session increases your risk of complications, and unprotected sun exposure afterward can undo your results and cause new pigmentation problems on the healing skin.
Cost and Number of Sessions
The average cost of laser skin resurfacing is around $1,829 per session, according to the American Society of Plastic Surgeons, though this varies widely based on the type of laser, the size of the treatment area, geographic location, and the provider’s expertise. A single aggressive ablative session will cost more upfront but may be the only treatment you need. A series of four to six gentler non-ablative or IPL sessions could cost a similar total amount spread across multiple visits.
Results from ablative treatments can last for years, though your skin will continue to age and accumulate new sun damage over time. Many people schedule a maintenance session every one to three years, or use periodic IPL or non-ablative treatments to preserve their results between more intensive procedures.
Matching the Laser to Your Damage
There is no single best laser for sun-damaged skin, but there is a best laser for your specific situation. Fractional CO2 remains the most powerful option for comprehensive photodamage involving wrinkles, texture, and pigmentation together. Hybrid fractional lasers deliver strong results with a more manageable recovery. IPL is ideal when discoloration and redness are the primary concerns. Picosecond lasers excel at breaking up stubborn pigment with minimal risk of darkening, especially in medium and darker skin tones. Non-ablative fractional lasers suit mild damage or patients who need zero downtime.
A board-certified dermatologist who specializes in laser procedures can evaluate your specific pattern of damage, skin type, and tolerance for downtime, then recommend the approach most likely to give you the results you’re looking for.
