"i&#039;m 18 and have severe acne all over my back- at least, i did. 4 days after starting amnesteem my acne was almost all gone. 2 weeks into the treatment and i don&#039;t have a single pimple or blackhead. the side effects are taking their toll, however. red burned face from getting sunlight for over 2 minutes. dry flaky face. dry bleeding lips. good news is that my doctor said i am responding so well that instead of 5 months, i may only need 2-3 months."
