Clean skin gently- Gently wash your face with a mild cleanser [according to the type of your skin], once in the morning and once in the evening, as well as after heavy exercise. It is also important to shampoo your hair regularly. If you have oily hair, you may want to wash it every day. Wash your face with plain water frequently.
Avoid frequent handling of the skin. Avoid rubbing and touching skin lesions. Squeezing, pinching or picking blemishes can lead to the development of scars or dark blotches.
Shave carefully- Shave gently and only when necessary to reduce the risk of nicking blemishes.
Choose cosmetics carefully.
Self-care measures and over-the-counter medicine have not helped after several months; Your acne is severe or getting worse; then contact your dermatologist.
Products such as facial scrubs, astringents and masks generally aren't recommended because they tend to irritate skin, which can aggravate acne. Excessive washing and scrubbing also can irritate skin. If you tend to develop acne around your hairline, shampoo your hair frequently.
Try over-the-counter acne lotion to dry excess oil and promote peeling. Look for products containing benzoyl peroxide, resorcinol or salicylic acid as the active ingredient.
Avoid irritants. You may want to avoid oily or greasy cosmetics, sunscreens, hair-styling products or acne concealers. Use products labeled "water-based" or "noncomedogenic."
Protect yourself from sun. For some people, the sun worsens acne.
