What it is: An oil-serum that delivers a delicate, non-oily texture as it acts against skin dullness and dryness resulting from hormone imbalances and stress. What it does: With a high concentration of white mucuna bean essence, the oil serum helps to improve overall skin sensitivity. How to use: Use at night, after preparing your skin with Lotion (sold separately). Add about four drops of the oil serum into your hand and gently massage into skin.
