1. Pressing your phone to your face
A phone screen collects oil, makeup and bacteria, and the pressure and heat against your cheek and chin can add to breakouts. Wipe your phone often with an alcohol-based wipe and use earbuds or speakerphone for long calls.
2. Over-scrubbing
When skin breaks out, it's tempting to scrub harder. Rough scrubs and frequent washing irritate the skin and can make inflammation worse. Wash twice a day with a gentle cleanser, using your fingertips, and pat dry.
3. Dirty pillowcases
Pillowcases collect oil, sweat, hair product and dead skin. Change yours at least once or twice a week. Friction and heat trapped against the skin, from helmets, headbands or tight clothing, can also cause breakouts, called acne mechanica.
4. Skipping makeup brush cleaning
Brushes and sponges build up oil, bacteria and old makeup. Wash them weekly with gentle shampoo and warm water, and let them air-dry. Choose makeup labeled non-comedogenic or oil-free.
5. Diet
Research links high-glycemic foods, such as sugary drinks, white bread and sweets, and in some people skim milk, to more acne. A diet rich in vegetables, fruit, whole grains and lean protein supports healthier skin. Diet alone rarely clears acne, but it can help.
6. Stress and poor sleep
Stress hormones can increase oil production and inflammation. Regular sleep, exercise and stress-management habits are good for both your skin and your overall health.
7. Picking and popping
Squeezing a pimple pushes bacteria and debris deeper into the skin, which raises the risk of more inflammation, dark marks and permanent scars. Leave pimples alone, or use a spot treatment with benzoyl peroxide or salicylic acid.
When to see a dermatologist
If over-the-counter products haven't helped after two to three months, or if your acne is painful, deep or leaving scars, a dermatologist can prescribe treatment that works. Early treatment is the best way to prevent acne scars.
