Kojic Acid Skin Treatments
When it comes to skin treatment, kojic acid is a renowned name. With less melanin secretion, the skin tone will be lighter. Unlike chemicals like hydroquinone, kojic acid is a natural substance formed from fermenting rice. Koji is a mushroom that secretes kojic acid. Kojic acid may be a safe alternative to chemical skin whitening treatments, but is it really safe? There is a research that suggests that kojic acid may be carcinogenic in large amount. It is also used to preserve the freshness and color of foods. Melasma is known to be cured by some kojic acid treatments and is used for melasma treatment and to remove age spots.
Kojic acid is unstable when added to cosmetic formulations, once it exposed to the sun or air, it turns to brown and its efficiency is lost. Some companies use a more stable version of it-kojic dipalmate. However it is not as effective as pure kojic acid. Its pigmentation inhibiting property certified it to be used as a skin whitening treatment. Its efficiency is out of the question but its safety is. Kojic acid is effective to use on freckles, acne and dark spots on the skin. It is also used for uneven skin pigmentation, stretch marks and other skin discoloration. It also keeps cells healthy by reducing free radicals. There are many products that contain kojic acid, creams, gels, soaps and serums.

One inconvenience of it is that it makes skin very sensitive from frequent use. One may even contract allergic contact dermatitis.

Doctor prescription is really needed before buying any of these products that affects skin function. Kojic acid maybe safer than hydroquinone, but still it poses some risks.
