Your Face Looks Sallow

As you get older, your skin cells don't turn over as rapidly, while the blood flow to your skin changes, causing cells to become irregular and your face to look sallow and dull. The solution is to exfoliate and moisturize regularly. For one-step ease, use a moisturizer with retin-A or glycolic acid, both exfoliating ingredients, at night. Or try a face scrub in the shower in the morning. Another tip: Start the day with two glasses of water and a cup of Greek yogurt. Yogurt's calcium increases cell turnover and keeps the jawbone strong, helping you avoid a sunken look.
