A member asked:

How long would retin a (tretinoin) take to clear acne?

A doctor has provided 1 answer

Acne: Most acne treatments, including retin a, (tretinoin) take a minimum of 2 weeks to start working and more likely 6-8 for better effect. Most studies looking at effectiveness of acne medicines look at the skin after 12 weeks. Unfortunately not overnight like most teens would like.
