What causes acne? Acne develops when hormonal shift causes and overproduction of oil and cells in the skin follicle which produces a traffic jam that plugs the opening of the pores and causes follicle beneath to swell. I have suffered with acne as long as I could barely forget. Probably, at around 13, I got my first pimple on my face and they were right on my face until last year but left hilarious marks on my skin. However, I got rid of them on the recommendation of Aquashine BR by a friend.
