Two things have recently changed in my regime...I've begun shaving my face several times a week and using the Quasar MD 2x week. I've been using retin-a for years now, in addtn to my serums (vit c, etc), and SPF. All of a sudden my face looks HORRIBLE, my skin looks more mottled than ever and fine lines on cheeks are out in full force! What happened? Will my skin go back to normal? Thanks for the advice!
