Want to avoid orange palms, knees and elbows when you're using sunless tanning products? Before applying a sunless tanning product use a washcloth to exfoliate, especially in areas with thick skin such as your knees and elbows. This will help remove excess dead skin cells. Apply the tanner to your body in sections. Wash your hands with soap and water after each section to avoid discoloring your palms. Knees, elbows and ankles tend to absorb more of sunless tanning products. To dilute the tanning effect in these areas, gently rub them with a damp towel.
