Fractional Laser

A laser treatment that delivers energy in a grid of tiny columns rather than covering the whole skin surface at once, allowing for effective resurfacing with faster healing than traditional full-surface laser treatment.

What Is Fractional Laser?

Fractional laser refers to a method of delivering laser energy to the skin rather than a single specific laser type. Instead of treating the entire surface of the skin uniformly, a fractional laser creates thousands of tiny, precise columns of treated tissue surrounded by untouched skin. These columns of treated tissue stimulate the skin to repair and rebuild, producing new collagen and smoother, more even skin in the treated zones. The surrounding untreated skin acts as a reservoir of healthy tissue that supports faster healing than would be possible if the entire surface were treated at once.

The fractional delivery method was developed to bridge the gap between highly effective but high-downtime traditional ablative lasers and gentler non-ablative treatments with minimal downtime. By treating only a fraction of the skin at a time, fractional lasers can achieve meaningful improvement in wrinkles, scars, pigmentation, and skin texture while allowing most people to recover within five to seven days rather than the two weeks or more required by traditional full-surface ablative laser.

Fractional lasers fall into two main categories. Ablative fractional lasers, such as fractional CO2 and fractional erbium, physically remove the treated tissue columns, producing more dramatic results but requiring more recovery time. Non-ablative fractional lasers deliver heat into the skin without removing the surface, producing more gradual improvement with significantly less downtime. The right choice depends on the severity of the concern, the skin type, and how much downtime is acceptable.

What to Expect

Before treatment, a topical numbing cream is applied to the area and left for 20 to 30 minutes. During the procedure, the laser handpiece is moved systematically across the skin, delivering pulses of energy in the fractional grid pattern. The sensation during treatment is typically described as a warm prickling or mild stinging with each pulse. With adequate numbing most people find ablative fractional laser very manageable, though some discomfort is expected.

After an ablative fractional treatment, the skin will be red, swollen, and have a rough or sandpaper-like texture as the tiny treated columns heal. This typically peaks at 24 to 48 hours and then gradually improves. Most people are comfortable returning to daily activities within five to seven days, though redness can persist at a lower level for several weeks. Non-ablative fractional treatments produce less visible recovery, with redness and mild swelling settling within one to three days.

Results develop gradually as new collagen forms and matures over the weeks and months following treatment. Most people see meaningful improvement from four to six weeks, with the full result typically visible at three to six months. A course of two to four treatments spaced four to six weeks apart is commonly recommended for more significant concerns, while a single treatment may be sufficient for maintenance or milder concerns.

Who It’s For and Results

Fractional laser is suited to those with wrinkles and fine lines, acne scarring, sun damage and pigmentation, uneven skin texture, enlarged pores, and general skin quality concerns that have not responded adequately to gentler treatments. The ablative version is better for more significant concerns and produces more dramatic results. The non-ablative version suits those with milder concerns or those who cannot accommodate meaningful downtime.

Skin tone is an important consideration. Ablative fractional laser is safest and most predictable in lighter skin tones. In medium to deeper skin tones, the risk of post-inflammatory pigmentation is higher and requires a more cautious approach, appropriate preparation, and experienced provider selection. Non-ablative fractional treatments are generally safer across a broader range of skin tones.

When matched to the right candidate and concern, fractional laser produces significant improvements in skin quality that can be genuinely transformative for established scarring or significant photoageing. Results are long-lasting, though the natural ageing process continues and maintenance treatments over time help preserve the improvement.

Frequently Asked Questions: Fractional Laser

Ablative fractional laser physically removes the tiny columns of treated skin tissue, creating an open wound in each column that heals over several days. This produces more significant results because the treatment reaches deeper into the skin and triggers a more substantial healing and collagen-building response. Non-ablative fractional laser delivers heat into the skin without removing the surface, so there is no open wound. The skin stays intact, recovery is much quicker, but the results are more gradual and less dramatic than ablative treatment. Ablative is better for significant concerns where more impact is wanted. Non-ablative is better for milder concerns or when minimal downtime is essential.

A full-surface or traditional ablative laser treats the entire skin surface in the treatment area uniformly, removing the whole outer layer. This produces very significant results but requires substantial recovery time of two weeks or more. Fractional laser treats only a fraction of the surface at a time, leaving surrounding skin intact. This reduces recovery time considerably while still producing meaningful results. The trade-off is that fractional treatment may require more sessions than a single full-surface treatment to achieve the same level of improvement for very significant concerns.

Yes. Fractional laser is one of the most effective non-surgical treatments for acne scarring, particularly for rolling and boxcar scars that have a relatively smooth base. The laser stimulates new collagen in the treated columns, gradually improving the depth and visibility of depressed scars over a course of treatments. Ice pick scars, which are very narrow and deep, respond less predictably to fractional laser and may benefit from additional targeted approaches. The degree of improvement depends on the severity and type of scarring, with most people achieving a meaningful reduction in scar visibility rather than complete elimination.

This depends on the concern being treated and its severity. For general skin quality improvement and mild concerns, one to two sessions may produce a satisfying result. For moderate to significant scarring, pigmentation, or wrinkles, a course of three to four sessions spaced four to six weeks apart is commonly recommended. Ablative fractional treatments are more impactful per session and may require fewer total sessions than non-ablative to achieve the same degree of improvement. A provider will recommend the most appropriate programme after assessing the skin and discussing individual goals and tolerance for downtime.
