Scientists have now shown a key cause is the decline in the body's neuroendocrine system. This results in a reduction in the quantity and effectiveness of essential hormones and cell growth factors, ultimately leading to an inevitable aging process. These hormones and cell growth factors normally initiate cell repair mechanisms and in the skin promote production of new, replacement dermal cells. Without them the collagen loses its elasticity and the skin becomes slack and wrinkled. Moisture is no longer retained and a dry, thin, aging skin replaces the youthful plumpness.
Healing becomes less efficient and the effects of sun damage more evident. .
A tissue respiratory factor known as saccharomyces lysate extract is also added. RejuvaDerm relies upon the advantages of submicron emulsions that allow its unique natural hormone formula to pass through the upper stratum cernuum layers into the lower dermis where new skin cells begin their long migration to the outer surface that we expose daily to the harsh enviroment of everyday living. RejuvaDerm contain L - thyroxine and pregnelolone acetate which are naturally occurring hormones needed to stimulate new skin cell development. As we age, the production of these key substances begins to slow or even stop. Toxins begin to accumulate in skin cells and skin health gradually declines.
