Hello, i m 13 and a half years old and I started getting acne at the age of 12. My dermatologist recommended me to have the medication Tretivia 10 mg alternate day along with which gave me a Sebamed foamy face wash and a Sebamed clear gel which comes with it. He also told me to put Clin 3 in the morning and Nadoxin gel in the night. I ve been following this for little more than a month now while the course is for 3 months. I had a question, will all my acne finish in 3 months though it s not much but little of it is under my skin. Also are pimples under the skin called scars? And one more thing, once I finish this course, will my pimples come back? Thanks for the help:)
