The sebaceous glands on your face produce oil and are more active around your nose because of the larger pores in this area. The oil produced, known as sebum, may become excessive due to lack of proper skin care, a diet high in fats and everyday stress. Teenagers often produce excessive sebum caused by hormonal changes during puberty. You can't stop sebum production but you can take steps to make your face produce less oil.
Wash your face both in the morning and before you go to bed. Use a face wash specifically formulated for oily skin. Avoid using harsh soaps and hot water as these can irritate your skin and possibly cause excessive oil production.
Apply a toner to your clean skin. Choose a toner specifically for your skin type and apply with a cotton ball over your entire face to help remove any cleanser residue. Toners also help restore the pH balance of your skin while cleaning away excessive oils, impurities and dead skin.
Moisturize your face with an oil-free, noncomedogenic moisturizer or oil-control lotion. Choose a product that contains benzoyl peroxide or salicylic acid as well as a sunscreen with a sun protection factor of 15 or higher. Moisturizers and oil-control lotions help to replace the moisture lost when cleansing and toning.
Try oil absorbing products like an oil mattifier that helps absorb oils throughout the day. Carry powder-free oil blotting tissues with you to blot away excessive oils that may occur during the day.
Use noncomedogenic, water-based cosmetics. Oil-based cosmetics can aggravate oily skin.
