As much as we'd like to forget everything from our awkward teen years, some things (like acne) stick with us as we age. As this video from Women's Health explains, acne is common among women in their 20s and 30s as estrogen and progesterone levels continue to shift.

Pay attention to where pimples pop up for a clue to the culprit. Acne on your chin can be linked to eating lots of carbs or sugar, and zits near your hairline probably come from your sweat session at the gym. The best way to beat adult acne? Stick to a consistent skin care routine. That means washing your face two times a day, moisturizing, using SPF, and getting your beauty sleep!
