Laser Resurfacing

A category of laser treatments that improve the skin by removing damaged surface layers, stimulating new collagen, and triggering the growth of fresher, smoother skin. Ranges from gentle with minimal downtime to intensive with significant recovery.

What Is Laser Resurfacing?

Laser resurfacing is a broad category of professional skin treatments that use laser energy to improve the surface quality of the skin. Depending on the type of laser and the settings used, this can involve removing the outer layers of damaged skin entirely, remodelling the deeper layers without disturbing the surface, or a combination of both. The common thread across all laser resurfacing treatments is the stimulation of the skin’s natural repair and rebuilding response, which produces new collagen, smoother texture, and more even tone in the treated area.

Laser resurfacing sits across a spectrum of intensity. At the gentler end, non-ablative laser treatments deliver heat into the deeper skin layers without removing the surface, producing gradual improvement with minimal downtime. At the more intensive end, fully ablative laser treatments remove the outer skin layers completely, producing significant results but requiring a meaningful recovery period. In the middle sits fractional laser resurfacing, which treats only a fraction of the skin at a time and offers a balance of meaningful results with a more manageable recovery.

The concerns most commonly addressed by laser resurfacing include wrinkles and fine lines, acne scarring, sun damage and age spots, uneven skin texture and tone, enlarged pores, and crepey or loose skin quality. The choice of laser type and approach depends on the specific concern, its severity, the individual’s skin type and tone, and how much downtime is acceptable.

What to Expect

The experience of laser resurfacing varies significantly depending on the type and intensity of treatment. For non-ablative laser treatments, a topical numbing cream is typically applied beforehand and the procedure produces a warm prickling sensation. Recovery is minimal, with some redness and mild sensitivity settling within a day or two.

For fractional ablative treatments such as fractional CO2 or fractional erbium, the procedure is more intensive. Numbing cream and sometimes injectable local anaesthetic are used to manage the stronger sensation during treatment. After a fractional ablative treatment, the skin will be red, swollen, and have a rough texture as the tiny treated columns heal, typically over five to seven days. Redness can persist for several weeks at a lower level as the new skin matures.

For fully ablative laser resurfacing, the most intensive category, the recovery period is the most significant, with the skin raw, red, and healing visibly for ten to fourteen days, and redness persisting for several weeks to months. The results are correspondingly more dramatic for appropriate candidates.

Who It’s For and Results

Laser resurfacing is suited to those with skin concerns that have not responded adequately to more superficial treatments. The appropriate type depends on the severity of the concern and the amount of downtime acceptable. Milder concerns and those who cannot accommodate downtime are suited to non-ablative approaches. More significant concerns such as moderate to severe wrinkles, acne scarring, or significant photoageing may benefit from fractional or fully ablative approaches.

Skin tone is a significant consideration. Ablative laser resurfacing is safest and most predictable in lighter skin tones. In darker skin tones, the risk of post-inflammatory pigmentation is higher and requires careful assessment, appropriate preparation, and experienced provider selection. Non-ablative and some fractional approaches carry a lower pigmentation risk and are more broadly applicable across skin tones.

When matched appropriately to the concern and candidate, laser resurfacing can produce dramatic and long-lasting improvements in skin quality. Wrinkles are visibly reduced, scars improve, pigmentation clears, and the overall quality and texture of the skin is substantially better. The results are generally long-lasting, though the natural ageing process continues and periodic maintenance treatments help preserve the improvement over time.

Frequently Asked Questions: Laser Resurfacing

Ablative laser resurfacing physically removes the outer layers of the skin, creating a wound that heals over several days to weeks as new, fresher skin grows back. It produces more dramatic results but requires a meaningful recovery period. Non-ablative laser resurfacing delivers heat into the deeper skin layers without removing the surface, so the skin stays intact and recovery is minimal. Results are more gradual and less dramatic than ablative treatment. Fractional laser falls between the two, treating only a fraction of the surface ablatively while leaving surrounding skin intact to support faster healing.

Recovery time depends on the type and depth of treatment. Non-ablative treatments typically involve one to three days of mild redness and sensitivity. Fractional ablative treatments involve five to seven days of visible healing, with redness continuing at a lower level for several weeks. Fully ablative resurfacing involves ten to fourteen days of active healing and several weeks to months of residual redness. The provider will give specific guidance on what to expect and how to care for the skin during recovery before treatment begins.

Yes. Laser resurfacing, particularly fractional CO2 and fractional erbium, is one of the most effective non-surgical approaches for improving acne scarring. It works by stimulating new collagen in the treated areas, gradually filling and smoothing depressed scars over a course of treatments. Rolling and boxcar scars tend to respond best. Ice pick scars, which are very narrow and deep, respond less predictably and may benefit from additional targeted approaches alongside laser. Most people with moderate to significant acne scarring see meaningful improvement over a course of three to four fractional sessions, though complete elimination of deep scars is not typically achievable.

Both laser resurfacing and chemical peels improve the skin by removing or remodelling the outer layers and stimulating renewal, but they do so through different mechanisms. Chemical peels use acids to dissolve the bonds between skin cells and remove the surface chemically. Laser resurfacing uses light energy to vaporise or heat the tissue. Laser tends to offer more precision in the depth and pattern of treatment, particularly with fractional delivery, and can address concerns such as deeper scarring and more significant photoageing more effectively than most chemical peels. Peels tend to be more accessible, less expensive, and require less preparation. The right choice depends on the concern, the skin type, and what level of treatment and downtime is appropriate.
