Sudden acne breakouts feel like something you should graduate from right around high school commencement. Or at least by college graduation, right?
Read on to discover more about what might be triggering your latest round of pimple-palooza, plus how to treat sudden acne breakouts and possibly prevent them in the first place.
As with many health-related conditions, causes of acne can vary. You can think of the source of sudden acne breakouts in adults kind of like a recipe with a long ingredient list, including any or all of these factors:
Clogged pores (often caused by dead skin cells hanging around too long)
Hair products, skin care products or makeup that don’t agree with your skin
Excessive or infrequent face washing
A few of the triggers for sudden acne breakouts are out of your control (see: the genes you’re born with and the medications you need to take for other reasons), but many zit causes are in your own hands — literally, as with your menu, cigarette use and skincare routines.
Acne can present itself in a variety of ways.
Pimples: When dead skin cells, extra oil or bacteria gets trapped in a pore, healthy skin bacteria can multiply, filling a pore with bacteria that makes it swell.
Cysts or nodules: Like more severe pimples, the bacteria can become seriously inflamed, tender and painful and possibly filled with pus.
Whiteheads: These occur when oil or dead skin cells plug a pore’s opening and create a white bump.
Blackheads: These are similar to whiteheads, except the build-up happens inside the pore. This leads to a chemical reaction in the air, which is where the dark hue comes from.
Our guide to the best skin care routine for acne is a great place to start cleaning up your beauty strategy.
In terms of lifestyle habits that can help prevent sudden acne breakouts in adults, lean into low-glycemic foods — those that won’t cause a major blood sugar roller coaster — and try to ease off the cow’s milk (Yogurt and cheese should still be okay.).
Aim to remove all makeup before your sweat sesh at the gym routine, wear clean workout clothes and use a clean towel to mop up perspiration. Shower, or at least wash your face, ASAP after you finish exercising.
Seek out skin and hair products that list “oil-free,” “non-comedogenic” or “non-acnegenic” on their label, clean your makeup brushes once per week and remove all makeup fully before bed each night. As a general rule, wash your face twice per day with a mild cleanser, plus after any time you sweat.
