Acne isn’t just a problem for teens. According to studies, those pesky zits and pimples can pop up at any age. Whether it’s your diet, environment or stress that’s to blame, you don’t have to suffer helplessly. To get the skinny on acne, we talked to board-certified dermatologist Cynthia Bailey, M.D., president and CEO of Advanced Skin Care and Dermatology Physicians, Inc. and founder of DrBaileySkinCare.com. Here, she shares her best tips on how to choose the right acne cleanser for you, as well as how to use it to get the best results.
Light therapy – Light therapy uses non-laser sources of light that help prevent everyday pimples and pustules. More severe acne lesions don’t respond as well to light therapy, however. Light therapy has lower potential side effects than some treatments and also is relatively affordable. While it produces results, light therapy will not clear acne completely.
P. acnes also provokes skin inflammation by altering the fatty composition of oily sebum. Oxidation of the lipid squalene by P. acnes is of particular importance. Squalene oxidation activates NF-κB (a protein complex) and consequently increases IL-1α levels. Additionally, squalene oxidation leads to increased activity of the 5-lipoxygenase enzyme responsible for conversion of arachidonic acid to leukotriene B4 (LTB4). LTB4 promotes skin inflammation by acting on the peroxisome proliferator-activated receptor alpha (PPARα) protein. PPARα increases activity of activator protein 1 (AP-1) and NF-κB, thereby leading to the recruitment of inflammatory T cells. The inflammatory properties of P. acnes can be further explained by the bacterium's ability to convert sebum triglycerides to pro-inflammatory free fatty acids via secretion of the enzyme lipase. These free fatty acids spur production of cathelicidin, HBD1, and HBD2, thus leading to further inflammation.
Another once-daily gel your dermatologist might prescribe for acne is Aczone 7.5 percent. The active ingredient, dapsone, is both antimicrobial and anti-inflammatory, and it’s proven to help with blackheads, whiteheads, and deeper painful pimples. Oftentimes, Aczone is used alongside other acne treatments. And like many of those other remedies, Aczone can cause skin to dry out.
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.
