"i suffered from chin acne for about 5 years. the spots (i think hormonal) varied from the big under-your-skin ones to white heads and i would literally get a new one every few days. i&#039;d tried loads of different treatments from the docs, including antibiotics, and even went for face peels but nothing helped long term. my brother recommended tretinon and i was dubious at first but decided to give it a try. bought the gel online (but i think you can get it from your doctors too). first few weeks i saw a huge improvement in the amount of i was getting although my skin did peel a fair bit. i started moisturising on alternate days and two months later the difference is incredible! had no new spots for a month and even my acne scars are fading!"
