Both Body Complex and Youth Body Serum are hydrating, nourishing, and can assist in the prevention and repair of cellular damage. However, Body Complex has gentle yet highly effective exfoliation properties that Youth Body Serum does not. This makes Body Complex excellent for individuals with dry skin or skin thickened as the result of some skin conditions, including psoriasis or keratosis pilaris. Youth Body Serum is also excellent for dry skin and may be combined with Body Complex for keratosis pilaris and other skin conditions. Body Complex is a light lotion, while Youth Body Serum is a fast-absorbing weightless mist.
