The DEEP line of products is based on the Science of Celleration, a term coined by Dr.Hamilton to describe the skin aging process. Two things happen when skin ages: first, there is a proliferation of free radicals, products mostly by sun exposure, which damages the skin. Second, the proliferation of free radicals slows down the rate at which collagen is produced. Wrinkles appear as a results of collagen loss. Together, the DEEP Delivery Enhancer and the DEEP Cell Activate accelerate collagen production and deceleration free radical damage, helping fight the signs of aging.
