Extensive research has been conducted into skin whitening techniques for the cosmetics industry, resulting in a wide range of medically prescribed products. Dermatological research shows that pigmentation problems are the number one concern for skin patients*.

Research also shows that the ingredient that can treat pigmentation most effectively is Polyol Soluble Licorice Extract P-T (40) (extracted directly from licorice root). This ingredient prevents the occurrence of melanin biosynthesis (see comparing below, IC₅₀ table), greatly limiting damage caused by pigmentation through safe and effective application. Studies have also revealed the properties of Stearyl Glycyrrhetinate, a highly effective ingredient that prevents inflammation, irritation, and skin allergies resulting from exposure to the sun (UVB induced-erythema). (see picture)

In addition to these wide ranging properties, licorice root extract is known to hinder the skin’s aging process, while acting as an antimicrobial agent.

Half maximal inhibitory concentration (IC₅₀)

This table represents the concentration of whitening agents (ug/mL) which use to stop Tyrosinase (enzyme that catalyzes the production of skin pigmentation) for obtaining 50% of a maximum effect.

P-T(40) showed the strongest effect compared to many common whitening agents (58 times stronger than kojic acid, 272 times than ascorbic acid (vitamin C), 2000 times than Arbutin and 16 times than Hydroquinone).

Derived from Licorice, polyol soluble licorice extract P-T (40) can hinder unwanted pigmentation caused by exposure to ultraviolet rays. The formula greatly reduces and prevents outbreaks of blemishes, freckles, and uneven skin tone, stalls the skin’s natural aging process, and provides anti-microbial protection. The inclusion of another licorice extraction stearyl glycyrrhetinate helps reduce irritation, inflammation, and erythema – commonly caused by long exposure to the sun. This also prevents discoloration of the skin. In addition, humectant with an amino acid blend and hyaluronic acid inject the skin with vitamins C and E, protecting against damage caused by free radicals.

After your usual regimen (preparing skin with antioxidant), smooth cream evenly onto face, neck and chest, let it absorb thoroughly into the skin.

Follow with a SAL moisturizer and sun care in the day time.
