In addition to your skin-care routine, probiotics can also help with acne flare-ups. Research suggests that restoring balance to an unhealthy gut may help reduce acne-triggering inflammation. That's where probiotics, which encourage healthy bacteria, come in, says Dr. Engelman. Get your fill from probiotic-rich foods and drinks, such as yogurt, saur kraut, pickles, kimchi, kombucha, kefir, or miso paste, suggests Dr. Gmyrek. If you want to pop a supplement, experts say to opt for one with a high organism count—30 to 50 billion colony-forming units (CFUs)—and to stick with well-studied strains like lactobacillus. Using probiotics topically may also keep bumps at bay. The theory is that probiotics shield cells from bad bacteria, calm inflammation, and have an antimicrobial effect. Two to try:

Lastly, if, like clockwork, your acne flares up right around the time you have your period, try taking 100 milligrams of vitamin B6 in the days leading up to and during it. This vitamin reduces the flare-up of breakouts because it prevents an excessive imbalance of the hormones, says Dr. Thornfeldt. Spearmint tea might help too. The minty beverage is not only anti-inflammatory and antibacterial but has also been shown to block acne-stimulating androgens. In a study done on women with polycystic ovarian syndrome, a condition marked by high androgen levels, women who drank the tea twice a day had significantly lower levels of the male hormones after one month.
