Clindamycin / tretinoin
"I'm 20 years old, and I had severe cystic acne after my dermatologist gave me trentinoin. It was so bad but I switched to another dermatologist because of my insurance and she gave me Aczone and Ziana with Solodyn pills. My skin is so clear and soft, it's unbelievable. I only have some dryness around my mouth, but besides that my skin is the best it's ever been and I never thought I'd ever be writing a review about something actually working."
