What aging can bring: Wrinkles, brown spots, skin cancer.
What the research shows: Sun exposure and smoking can cause the loss of collagen and elastin and changes in DNA that can lead to skin cancer. Avoiding these stressors is “the most important thing to for skin,” says Kenneth Beer, a dermatologic surgeon in West Palm Beach, Florida. Antioxidants will help keep damage at bay by “allowing the skin to repair itself,” says Beer.
What you can do: Drink at least one cup of green tea (a powerful antioxidant) daily, and be sure to get enough vitamins C and E. Use a broad-spectrum sunscreen (one that protects against both UVA and UVB rays) of at least SPF 30 every day; check the label for one or more of these ingredients: titanium dioxide, zinc oxide, and Mexoryl. Topical application of green tea and vitamins C and E, which are found in many anti-aging products, helps boost the skin’s ability to fend off free-radical damage. And cover up outside whenever possible: Sun exposure can also lead to brown patches.
