Eighth Day

Eighth Day was born when Dr. Nakhla made the connection between the stem cells and nutrient-rich membranes he was using to heal open wounds and the transformative effect the same blend of synthetic bioidentical peptides, growth factors and amino acids could deliver deep within the skin via high-potency topical delivery systems. Eighth Day formulas are bioidentical – that is, we use synthesized ingredients that are biologically identical to the molecules already found in your skin. By doing so, we speak the language of skin and communicate directly to skin cells in their own native tongue. Harnessing the power of modern skin technology to effect real results.
