Want good skin? Watch your diet. Higher intakes of vitamin C and a lower intake of fats and carbohydrates are associated with better appearance as your skin ages. Changing your diet will help your looks. Foods rich in antioxidants, such as fish, fruits, and vegetables, seem to help
Your anti-aging cream may contain vitamin C or E. Put these antioxidants to work from the inside, too. Eating foods rich in these vitamins, plus the mineral selenium, can help protect your skin against sun damage. They may even help reverse signs of aging, like wrinkles and skin
Caffeine in coffee and tea is dehydrating, so it may cause your skin to dry out. But a study found that when applied topically to skin, caffeine may help reverse sun damage and lower risk of some skin cancers
Every day, your skin comes in contact with pollution -- cigarette smoke, car exhaust, or smoggy air. Keep skin healthy by keeping it clean. Depending on the needs of your skin, you can cleanse your face with a gentle soap or wash, or exfoliate nightly with gentle scrubs and toners to remove dead skin cells, and then apply a retinoid cream and moisturizer. (Oily skin still needs moisturizer; look for oil-free products.)
Cold weather and wind bring on dry, flaky skin and can make eczema and rosacea worse. It's not just the weather outside -- dry heat indoors is harsh on skin, too. Fight back by using a humidifier at home, drinking lots of water, and applying moisturizer throughout the day. Remember the sunscreen when you go out.
