Facial Scars from Laser Hair Removal and Fraxel

Depressed scars in ethnic skin particularly resulting from prior laser surgery warrants a more conservative approach. I would recommend regular microdermabrasion and topical retinoid under supervision of a board-certified dermatologist.

I have seen skin depressions from different lasers and for different reasons. Most likely, the YAG laser caused some injury to the subdermis of the skin and atrophy or loss of volume occurred. This created the depressions that you can see. They are usually relatively subtle, but obviously not so subtle to the person that has them.
I treat these like acne scarring. You can fill them, if possible, with fat, Juvederm, Restylane, Radiesse, or any other filler you desire. With your darker skin type, the only other option that comes to mind would be to use the Sciton Profractional laser. I have had great results using this laser for acne scarring, pox marks, and surgical scars of the face. You would want to be very careful with the treatment and use relatively low settings, but it should help at the very least.
Certainly dermaroller or needling could help as well, but I find that treatment to be less reliable.
