I can understand your concern for pimples
. As a young girl it is really ery frustrating to get pimples and its marks. Tretiva is a very good medicine for pimple and it takes minimum of 8-12 weeks to start its good effect. AS you taken it for just 6 weeks so it will be difficult to predict the effect. I suggest you to talk to your dermatologist
and have good follow up so that you can be benefited best.
