Have you noticed that pimples on the back and chest are much tougher to treat than blemishes on your face? Well, that's because the skin on these areas is thicker. You will need acne medications with stronger and higher percentages of bacteria-fighting ingredients to get rid of them. Although acne creams designed for the face do work, you have to be extra careful when applying. Most creams take several minutes to absorb, they may rub off on clothes before they can work their magic. I think it's best to use acne treatments in liquid form that absorbs into the skin faster.
