Skin respiratory factors (SRF)

Skin respiratory factors (SRF)

SRF also called tissue respiratory factors (TRF), have been used in cosmetics for their ability to renew and revitalize the skin through stimulation of cell respiration and metabolism.  Although a number of natural ingredients with the ability to enhance cell respiration have been isolated, the most abundant source is baker’s yeast. However, unlike beta-glucans, which are isolated compounds that stimulate cellular respiration, these elements are generally mitochondrial components which can enhance cellular energy. As skin ages, it exhibits a gradual physiologic fatigue, which is compounded by oxidative stress and environmental factors. This fatigue, is going paralleled by the progressive decrease in cellular energy and metabolism as well as diminished cellular function. The addition of ingredients to anti-aging skin care that contain mitochondrial cytoplasmic yeast extracts can result in the stimulation of cellular respiration followed by enhanced cellular metabolism, vitality, and increased cell renewal.

RNA is another anti-aging ingredients used by Rejuvenex which improve cellular energy through a “salvage pathway” and the ability of the skin’s cells to use oxygen.
