I’m a teen who’s struggled 3 years with acne I believe I’ve come along way knowing that I once had horrible cystic acne but no products seem to completely rid the larger zits I’ve tried the recommended amount of time with each and the ones that work are much too expensive, the one prescribed to me by my dermatologist dried out my skin and gave me weird dry skin patches even when putting large amounts of lotion!.any homemade ideas?????
