Keystone Advantage EXO and Keystone Advantage PAF cosmetics can be used alone or as part of aesthetic procedures like Erbium, CO2, Fractional, or Plasma devices to magnify results and improve the skin’s appearance. When a mildly ablative procedure is performed, Keystone Advantage PAF adds a healthy glow, better hydration, and a protective barrier to the skin. Keystone Advantage EXO provides additional exosomes, hydration, and protection during procedures with increased ablative energy. Keystone Advanced Gel contains nano‒lipid particles and natural proteins to nourish the scalp during hair procedures, granting a fuller, thicker head of hair.
