After a VI peel, which is supposed to treat brown pigmentation, I got more! I called my dermatologist, (who didn't perform the peel), and she suggested Triluma. I already use Tret .05% almost every night on my face. Will spot treating with Triluma, after reg application of Tret cause too much irritation? I know Triluma has same % tret as my reg Tret, but I didn't know how the combo of corto,tret,&hydroc (Triluma) would react with regular Tret. Thank you!!
