Clindamycin / tretinoin
"I've used Veltin for about 3-5 months , but i get lazy so I'll say like 2 months . I've gotten complements abouy that it got better since last year , people will rate me a 7 or 8. If i used it more often , like every night I know it would be much more clearer and you can really see the changes about a week or two but you have to be patient."
