Because it limits the effects of tyrosinase, kojic acid is an effective skin lightener and birghtener. Used extensively in the Asian market where fair skin is considered a sign of luxury, kojic acid is finding a new market in the western world with our aging Baby Boomers. Kojic acid is used to reduce dark spots, including freckles and age spots.
Derived from fungus, kojic acid is used extensively in lotions, creams and serums for the face. It provides excellent effects in evening out skin tone.
This material is 98% pure or better. It is supplied as a free-flowing white to off white powder. It is freely soluble in water.
Use rate is 1% - 5% (one percent to five percent) of the total batch weight. Increased use rates may cause skin sensitization. Always test first.
Adding kojic acid to formulation is easy. Since this material is water soluble, simply measure out the required amount and dissolve into the water phase of your formula. If you have an already existing lotion to which you would like to add kojic acid, such as our Alba Botanica lotion, dissolve the material in a small amount of distilled water and add to the base. Mix well with a stick blender or other mechanical stirrer.
Please note: Always apply a sun screen when using kojic acid. Because it is a tyrosinase inhibitor, it reduces the skin's ability to produce melanin, which protects against sunburn.
