LA MER Renewal Oil. Formulated for the face, but indulgent enough to be used on your hair and the body. You only need to use just three drops of oil a day to stimulate collagen and nourish skin. The oil is primarily intended to soften wrinkles and fine lines on the face, but you can use it as a straight-up moisturizer on your body, apply it to your nails to nourish and moisturize cuticles, and even use a dab to slick down frizz and fly aways.

It’s pricey, but I think it might be worth a try!
