Is it true that the laser treatment for acne scars will stimulate the collagen in my skin? what exactly does that do?

Collagen generating: One of the best treatments for acne scarring is fractionated laser. Depending on your skin color, texture and extent of scarring there are different laser options out there. A non-ablative fractionated laser like the fraxel re:store or dual has no real downtime, but requires multiple treatments. A fractionated co2 laser is more aggressive with about a week downtime, but may give faster results.
