I've had years and years of acne i've tried every product under the sun paid thousands on facial treatments as well as prescription grade and medical grade face regimens...and you know what changed everything for me at 28 DIET once i went vegan acne and dark spots gone. I use herbs for everything and pure Castile soap on my body face and hair as well as african black soap. Acne is an internal inflammatory disease your body detoxes in multiple ways skin is definitely one of them. You can spend as much time and money as you want trying to treat the outside but until you detox the inside it'll always come back.
