Moderation and regularity are good things, but not everyone can sleep eight hours, eat three good meals, and drink plenty of water a day. One can, however, still control acne despite one's frantic and unpredictable routine. Probably the most useful lifestyle changes one can make is to never to pick or squeeze pimples. Playing with or popping pimples, no matter how careful and clean one is, nearly always makes bumps stay redder and bumpier longer. People often refer to redness as "scarring," but fortunately, it usually isn't permanent. It's just a mark that takes months to fade if left entirely alone.
If you can kind of guess what's causing your skin problems, you stand a better chance of fixing them. For example, let's say you thought bacteria was causing your breakouts so you started using an antibiotic. But that didn't work, so then you tried not drinking milk, thinking your acne may be related to a food allergy, etc. One by one, as you go through all the potential causes of acne, you will eventually figure out what is making your skin break out, so you can reverse engineer a regimen that will prevent acne and keep your skin clear.
Superficial wounds, including those resulting from acne, usually heal without leaving a mark on the skin. However, if the dermis is damaged for any reason, a scar will probably be formed on the skin. In case of acne scars, inflamed lesions like a cyst, papule or pustule are usually the most common culprits. This inflammation occurs when the follicle or skin pores are blocked by bacteria, dead skin cells or excess oil. These factors cause the pore to swell and eventually lead to a break in the follicle walls. If this rupture is close to the surface of the skin, the damage to skin tissue will be minimal. However, deep breaks in the follicle wall can cause the infection to spread to the dermis, thereby destroying healthy skin tissue, which in turn leads to the formation of an acne scar.
