Are there any side effects by doing chemical peeling or laser besides redness?
and the positive result from these treatments is permanent right?
Acne scarring can be a difficult problem to treat. Generally, the improvements gained are incremental with each treatment, but it does make a positive change to the skin, and the confidence of the person. I find lasers such as the Fraxel laser or Carbon dioxide laser (fractional and non-fractional) to be the most effective lasers for acne scarring. Lasers can cause side effects such as redness (temporary) or changes in pigmentation (temporary or permanent) if used at too high a level, especially on those with olive or darker skin types. Therefore, for olive/darker skin types, we often recommend procedures such as skin needling (not a laser) for acne scarring, which tends to have much less chance of pigmentation changes post treatment , whilst still achieving an excellent level of improvement.
