Dermastir Ampoules – Kojic Acid

98.00

Kojic acid (5-hydroxy-2-(hydroxymethyl)-4-pyrone) is used in skin care formulations to lighten the skin, like another agent, hydroquinone. However, while hydroquinone works by inhibiting the activity of tyrosinase by acting as a melanocyte cytotoxic inhibitor and by increasing the cytotoxicity of melanocytes (melanin-producing cells), kojic acid lightens the skin solely by suppressing tyrosinase activity (by inhibiting catecholase activity of tyrosinase) in a non-traditional fashion. Kojic acid is revered worldwide for its skin-lightening properties and is commonly used in topical formulations to treat dark spots.

Description

Kojic acid (5-hydroxy-2-(hydroxymethyl)-4-pyrone) is used in skin care formulations to lighten the skin, like another agent, hydroquinone. However, while hydroquinone works by inhibiting the activity of tyrosinase by acting as a melanocyte cytotoxic inhibitor and by increasing the cytotoxicity of melanocytes (melanin-producing cells), kojic acid lightens the skin solely by suppressing tyrosinase activity (by inhibiting catecholase activity of tyrosinase) in a non-traditional fashion. Kojic acid is revered worldwide for its skin-lightening properties and is commonly used in topical formulations to treat dark spots. Kojic acid is a by-product in the fermentation process of malting rice for use in the manufacture of sake, the Japanese rice wine. There is definitely convincing research, both in vitro and in vivo, and also in animal studies, showing that kojic acid is effective for inhibiting melanin production (Sources: Biological and Pharmaceutical Bulletin, August 2002, pages 1045–1048; Analytical Biochemistry, June 2002, pages 260–268; Cellular Signalling, September 2002, pages 779–785; American Journal of Clinical Dermatology, September-October 2000, pages 261–268; and Archives of Pharmacal Research, August 2001, pages 307–311). Both glycolic acid and kojic acid, as well as glycolic acid with hydroquinone are highly effective in reducing the pigment in melasma patients (Source: Dermatological Surgery, May 1996, pages 443–447).

WHY AREN’T THERE MORE PRODUCTS AVAILABLE CONTAINING KOJIC ACID?

Kojic acid is an extremely unstable ingredient in cosmetic formulations. Upon exposure to air or sunlight it turns a strange shade of brown and loses its efficacy. Many cosmetics companies use kojic dipalmitate as an alternative because it is far more stable in formulations. However, there is no research showing that kojic dipalmitate is as effective as kojic acid, though it is a good antioxidant. Research shows that Kojic Acid is best presented and stored in glass ampoules.
