Hi, Four main factors cause acne:
Oil production, Dead skin cells, Clogged pores, Bacteria..
You can try to avoid or control mild acne with nonprescription products, good basic skin care and other self-care techniques:
Wash problem areas with a gentle cleanser.Twice a day, use your hands to wash your face with a mild soap and warm water. If you tend to develop acne around your hairline, shampoo your hair every day.
Avoid certain products, such as facial scrubs, astringents and masks, because they tend to irritate skin, which can worsen acne. Excessive washing and scrubbing also can irritate skin. And be gentle while shaving affected skin.
Try over-the-counter acne products to dry excess oil and promote peeling. Look for products containing benzoyl peroxide as the active ingredient. You might also try products containing sulfur, resorcinol or salicylic acid. Nonprescription acne medications may cause initial side effects — such as redness, dryness and scaling — that often improve after the first month of using them.
Avoid irritants. You may want to avoid oily or greasy cosmetics, sunscreens, hairstyling products or acne concealers. Use products labeled water-based or noncomedogenic, which means they are less likely to cause acne.
Use an oil-free moisturizer with sunscreen.For some people, the sun worsens acne. And some acne medications make you more susceptible to the sun's rays. Check with your doctor to see if your medication is one of these. If it is, stay out of the sun as much as possible. Regularly use a nonoily (noncomedogenic) moisturizer that includes a sunscreen.
Watch what touches your skin. Keep your hair clean and off your face. Also avoid resting your hands or objects, such as telephone receivers, on your face. Tight clothing or hats also can pose a problem, especially if you're sweating. Sweat and oils can contribute to acne.
Don't pick or squeeze blemishes. Doing so can cause infection or scarring.
