I am in my mid-twenties and had been suffering from painful and embarrassing acne for almost two years. My doctor could only offer me birth control or antibiotics-neither of which I wanted. I finally went into my local health store and the lady recommended this product. She said even though it's for teens, she had heard older people benefit from it too. I was amazed that it actually started working! I've been on it for two months now and my skin is SO much clearer(I take 3 per day)! I'm so happy! And when I checked to see if iHerb had this product, I was ecstatic to see that it was over $15 cheaper than at the store I origianlly got it from!
