Those of us who want to whiten or bleach our skin are more concerned with acquiring a product that achieves our objectives, quickly and effectively, than with the additives it contains. We may or may not understand that products containing hydroquinone, steroids, or mercury should be avoided at all costs, but what do we know about kojic acid, which is said to be as effective as hydroquinone in skin whitening and whitening formulations? ?
Kojic acid is derived from the Kogi mushroom that is commonly found in Asia. This acid is a byproduct in the fermentation process used to make a Japanese rice wine called “sake.” It possesses antioxidant, antibacterial, and antifungal properties, and is widely consumed in Japan for its perceived health benefits. There are several skin products that contain kojic acid for topical application, such as skin lightening facial peels, gels, night creams, serums, and soaps.
This ingredient is used in skin lightening products because it has the ability to actively suppress melanin production in the skin. Melanin is produced by melanocytes and is generated by the enzyme responsible for coloring hair, eyes and skin. This enzyme is called tyrosinase. Kojic acid negates this process by actively reducing melanin production in the top layer of the skin. Due to its tendency to turn brown when exposed to air or sunlight, cosmetic companies have turned to a strain called kojic dipalmitate, which has been shown to be more stable, but less effective than acid.
Kojic acid is also considered the main substitute for hydroquinone with regards to its effectiveness in the skin lightening process. Some companies have used the acid in conjunction with hydroquinone and glycolic acid in safer amounts of 2% or less, and this combination has been reported to be an effective treatment for melasma, chloasma, and other hyperpigmentation disorders. Kojic acid has also been commonly prepared with vitamin C, an effective natural skin whitener.
Some researchers have argued that although kojic acid is not toxic, it can cause contact dermatitis, an allergic reaction to a substance that can manifest as a rash or even blistering of the skin. It is important to note that there are alternatives to chemical-based skin bleaching or bleaching. There are homemade recipes and products formulated with 100% natural ingredients, so the issue of side effects is generally eliminated.
Contact your doctor before using any skin whitening or bleaching products to prevent damage to your skin and overall health.
