Fractional CO2 laser skin resurfacing is still the gold-standard for treating acne scars in younger patients. It is most effective for ice-pick acne scars, and is safer and requires less downtime compared to lasers that are fully ablative.
How Does It Work?
Fractional mode (acne scars): the ablative laser vaporizes the treated columns of skin on the surface, leaving normal skin inbetween. This fractionated mode is safer and carries less risk of scarring. Columns of old skin cells are destroyed extending deep into the middle layer of the skin (where scars lie). The laser targets scarred areas and old collagen, leaving areas of healthy tissue to regenerate through collagen and elastin production.
Improved skin texture and elasticity, and shallower acne scars result in younger-looking skin.
Non-fractional mode (for mole removal): This treatment is effective for the removal of moles of up to 2mm in diameter.
There is a risk of post-inflammatory hyperpigmentation (PIH) but this is often mild and transient. It is due to the risk of PIH that we recommend this for younger patients only.
