Did you know the unique compounds in a banana peel increase collagen production? So rather than buying pricey wrinkle creams, peel a banana! Rub the inside of the peel on your skin for 1 minute. Let sit for 15 minutes then rinse off. This will help diminish the appearance of fine lines and wrinkles. Also, because the peel is textured it gently sloughs off dead, dry skin!
