If your baby still has acne at 3- to 6-months-old, infantile acne may be the culprit. “These bumps tend to be more red and inflammatory,” says Dr. Kahn. “You’ll see more of the different types of acne than with baby acne, including pustules and cysts, not just whiteheads and blackheads.” And unlike baby acne, infantile acne is linked to family history: Your baby is more likely to get it if you or your partner had severe acne as a teen. Acne in older babies can also be an indication that your baby is more likely to have acne later in life. Like baby acne, infantile acne rarely needs treatment; if there’s a lot of redness and swelling, however, your doctor might want to treat it with a topical antibiotic.
Efforts to better understand the mechanisms of sebum production are underway. The aim of this research is to develop medications that target and interfere with the hormones that are known to increase sebum production (e.g., IGF-1 and alpha-melanocyte-stimulating hormone). Additional sebum-lowering medications being researched include topical antiandrogens and peroxisome proliferator-activated receptor modulators. Another avenue of early-stage research has focused on how to best use laser and light therapy to selectively destroy sebum-producing glands in the skin's hair follicles in order to reduce sebum production and improve acne appearance.
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.
