How do I figure out my skin type?

—Susan Summers, Sun City, AZ

Bobbi: Just pay attention to how your skin looks and feels. Do you need powder 15 minutes after you wash your face? If so, your skin is oily. I suggest a gel-based cleanser and a light oil-free moisturizer.

If your skin is tight or flaking however, it's dry, s try a creamy cleanser and thicker moisturizer. I swear by creams and balms that are super hydrating— they're perfect for this time of year. Plus, they give a smooth, plumped-up look and feel good on your skin.
