Question
Hi,
Generally, after an effective acne scar treatment e.g. fractional CO2 laser treatment, new collagen builds up progressively over the next 2-6 months and tends to be long-lasting translating to sustained improved clinical results that lasts years.
The caveat to the above is that not all acne scar treatments are equally effective so the collagen build-up relative to different treatments and even different treatment parameters used may differ significantly.
Hi there, One session of Picosure will give you noticeable results of 5-10% improvement with no downtime. PicoSure utilities the Focus Lens which targets the laser energy at 20x the usual strength deep under the skin, WITHOUT removing the top layer of the skin. Therefore it has no downtime. It is also proven to produce noticeable collagen at the areas where the scars are. For moderate improvement, I suggest that you will need 5-6 sessions of Picosure.
Isotretinoin intake while on acne scar treatment is considered generally safe based on the latest research studies published from 2014 onwards. Because acne scarring is associated with substantially reduced quality of life, early initiation of effective treatment is desirable. Ablative CO2 fractional laser treatment for acne scarring seems to be safe regardless of isotretinoin use (10-60 mg/d) [1]. Follow-up was for at least 6 months post-treatment to evaluate side effects. No major and permanent side-effects were seen.
