The skin around your eyes is some of the thinnest on your body. Treat it with TLC, or you risk exacerbating wrinkles, dark circles and bags. Never rub your eyes—if you have allergies, take antihistamines. Don’t use harsh scrubs around your eyes; products specially formulated for the eye area will be better for this fragile region. And use your ring finger to apply eye creams: It’s your weakest finger, so you’re less likely to tug at the skin or press too hard.
