Have spots on forehead. Diagnosed as lentigo. I think it's PIH. Also have melasma above eyebrows and lip. Melasma has responded well after picosure and retin a. 5 treatments of picosure thus far with not much improvement. Started using triluma after 4th picosure treatment and it lightened quite a bit. After 5th spots disappeared for 3 weeks but came back.It happens after every Picosure treatment but always comes back. What should I do? Continue picosure? What should the aftercare be?
