At 41 years old I truly thought my adult acne days were behind me. After 3 years on amocyline and using bp 5 and 10 in my early 30's it literally disappeared. Last week I had a very bad flare up which I am still trying to keep under control. I am devastated. Benzoyl peroxide is the only product which has ever made even a dint in my acne. I am scared to wash my face with any product, just using water and slathering on bp 5 each night , as cant get 2.5 in the UK. It has always been my saviour and I'm hoping it will work this time. If not,I'm stuffed.
