HEPES (Hydroxyethylpiperazine Ethane Sulfonic Acid)
HEPES, or Hydroxyethylpiperazine Ethane Sulfonic Acid, is a chemical buffer which is widely used in cell culture to maintain physiological pH. This amino-sulfonic derivative helps to improve skin and limits roughness.

Sodium Hyaluronate
The sodium salt of Hyaluronic Acid, Sodium Hyaluronate is known to be a moisturizing agent, viscosifier and emulsifier. Within our formulas, Sodium Hyaluronate helps hydrate, replenish and refine skin texture.

Urea
An enzyme activator naturally present in the surface layer of the skin (epidermis), Urea accelerates the natural process of cell renewal through the exfoliation of dead surface skin cells. The ingredient has a water binding effect in the top layers of the skin thus acting as a natural moisturizing agent in human skin.
