I just finished my sixth session with this particular laser and I wanted to know if it was ok for my skin type. I've home all of these sessions with no problems until this time. I think I got singed a little by the laser this time. I'm getting laser on my underarms and I fear I'm also getting hyper-pigmentation from the laser as well. What can I do to help the hyper-pigmentation as well as protect my skin from the laser?
