Acne appears when a pore in our skin clogs. This clog begins with dead skin cells. Normally, dead skin cells rise to surface of the pore, and the body sheds the cells. When the body starts to make lots of sebum (see-bum), oil that keeps our skin from drying out, the dead skin cells can stick together inside the pore. Instead of rising to the surface, the cells become trapped inside the pore.
Contrary to the marketing promises of “blemish banishers” and “zit zappers,” immediate results are not the trademark of acne treatments — a frustrating truth to anyone suffering through a breakout. And while pimples are personal (your stress-induced spots will look and act differently than your best friend’s breakout), the best acne treatments will include a regimen of products to hit all of acne’s root causes. We tested 43 kits to find the most well-rounded breakout-fighting solutions on the market.

Pimples are raised red spots with a white center that develop when blocked hair follicles become inflamed or infected with bacteria. Blockages and inflammation that develop deep inside hair follicles produce cystlike lumps beneath the surface of your skin. Other pores in your skin, which are the openings of the sweat glands, aren't usually involved in acne.
