"cress, i am also over 40 years of age and african american with adult acne, and i couldn&#039;t find a regimen for my recurring acne problems/breakouts. i was prescribed solodyn a couple weeks ago, and so far i like the results. i haven&#039;t noticed any darkening to my skin, however i will post again within 2-3 months to inform if i noticed any discoloration to my skin. i&#039;m using elta md broad spectrum spf 40 as part of my skin regimen, as advised by my dermatologist. i am not often too exposed to the sun, however the little amount of time i am exposed to the sun, the sunscreen comes in handy."
