How to know if tretinoin is working?
You may notice tretinoin starting to work within 2 to 3 weeks, but it can take 6 weeks or more to experience the full benefit. If you don't see improvement within 12 weeks, or if you have significant improvement and wonder if you should start using it less frequently, talk to your doctor.
