What Is Acne and What Causes It?
Acne is a condition of the skin that shows up as different types of bumps. These bumps can be blackheads, whiteheads, pimples, or cysts. Teens and oily skin type people get acne because of the hormonal changes that come with puberty.
The hair follicles, or pores, in your skin contain sebaceous glands (also called oil glands). These glands make sebum, which is an oil that lubricates your hair and skin. Most of the time, the sebaceous glands make the right amount of sebum. As the body begins to mature and develop, though, hormones stimulate the sebaceous glands to make more sebum.
Pores become clogged if there are too much sebum and too many dead skin cells. Bacteria (especially one called Propionibacterium acnes) can then get trapped inside the pores and multiply. This causes swelling and redness — the start of acne.
If a pore gets clogged up and closes but bulges out from the skin, you’re left with a whitehead. If a pore gets clogged up but stays open, the top surface can darken and you’re left with a blackhead. Sometimes the wall of the pore opens, allowing sebum, bacteria, and dead skin cells to make their way under the skin — and you’re left with a small, red bump called a pimple (sometimes pimples have a pus-filled top from the body’s reaction to the bacterial infection).
Clogged pores that open up very deep in the skin can cause nodules, which are infected lumps or cysts that are bigger than pimples and can be painful. Occasionally, large cysts that seem like acne may be boils caused by a staph infection.

HOW TO PREVENT & IMPROVE?
1. Keep your face clean
Whether or not you have acne, it’s important to wash your face twice daily to remove impurities, dead skin cells, and extra oil from your skin’s surface. Washing more often than twice daily is not necessarily better; it may do more harm than good. Use warm, not hot, water and a mild facial cleanser. Using a harsh soap (like deodorant body soap) can hurt already inflamed skin and cause more irritation.
Avoid scrubbing your skin harshly with a washcloth, an exfoliating glove, or loofah (a coarse-textured sponge). Gently wash it with a very soft cloth or your hands. Always rinse well, and then dry your face with a clean towel. (Toss the towel in the laundry hamper, as dirty towels spread bacteria.) Also, use the washcloth only once.
2. Moisturize
Many acne products contain ingredients that dry the skin, so always use a moisturizer that minimizes dryness and skin peeling. Look for “noncomedogenic” on the label, which means it should not cause acne. There are moisturizers made for oily, dry, or combination skin.
3. Try an over-the-counter acne product
These acne products don’t need a prescription. Most of them have ingredients such as benzoyl peroxide, salicylic acid, glycolic acid, or lactic acid, which curb bacteria and dry your skin. They may cause drying or peel so start with a small amount at first. Then you can adjust how much you use and how often. Another option is a new OTC topical retinoid gel (Differin 0.1% gel). It works to actually keep the acne from forming. Use these products with caution if you have sensitive skin.
4. Use makeup sparingly
During a breakout, avoid wearing foundation, powder, or blush. If you do wear makeup, wash it off at the end of the day. If possible, choose oil-free cosmetics without added dyes and chemicals. Choose makeup that is labeled as “noncomedogenic,” meaning it should not cause acne. Read the ingredients list on the product label before buying.
