Depigmenting agent /for skin lightening/

Melasma is a chronic and recurrent disorder. It has been underdiagnosed and undertreated due to lack of effective therapies and the perception that it is merely a cosmetic nuisance. Hydroquinone, corticosteroids, licorice extracts and kojic acid have been used as monotherapy to treat melasma. However, the present standard of care in melasma therapy is combination therapy. To date, the most effective treatment is a triple-combination agent that contains hydroquinone 4%, tretinoin 0.05% and fluocinolone acetonide 0.01%...
Rendon MI; J Drugs Dermatol (5 Suppl):S27-34 (2004)
... Combination regimens, including frequent applications of superficial- and medium-depth chemical peels, appear to be particularly effective and well tolerated in dark-skinned patients with melanosis. Post-inflammatory hyperpigmentation is the result of excess pigment deposition following an inflammatory skin disorder. Topical tretinoin, hydroquinone, azelaic acid, kojic acid, and glycolic acid peels have been employed with variable degrees of success...

Facial and neck pigmentations are ... common in middle-aged women, and are related to endogenous (hormones) and exogenous factors (such as use of cosmetics and perfumes, and exposure to sun radiation). Melasma (chloasma) is the most common cause of facial pigmentation, but there are many other forms such as Riehl's melanosis, poikiloderma of Civatte, erythrose peribuccale pigmentaire of Brocq, erythromelanosis follicularis of the face and neck, linea fusca, and cosmetic hyperpigmentations. Treatment of melasma and other facial pigmentations has always been challenging and discouraging.... Several hypopigmenting agents have been used with differing results. Topical hydroquinone 2 to 4% alone or in combination with tretinoin 0.05 to 0.1% is an established treatment. Topical azelaic acid 15 to 20% can be as efficacious as hydroquinone, but is less of an irritant. Tretinoin is especially useful in treating hyperpigmentation of photoaged skin. Kojic acid, alone or in combination with glycolic acid or hydroquinone, has shown good results, due to its inhibitory action on tyrosinase. Chemical peels are useful to treat melasma: trichloroacetic acid, Jessner's solution, Unna's paste, alpha-hydroxy acid preparations, kojic acid, and salicyclic acid, alone or in various combinations have shown good results. In contrast, laser therapies have not produced completely satisfactory results, because they can induce hyperpigmentation and recurrences can occur. New laser approaches could be successful at clearing facial hyperpigmentation in the future.

Antioxidants
Naturally occurring or synthetic substances that inhibit or retard oxidation reactions. They counteract the damaging effects of oxidation in animal tissues. (See all compounds classified as Antioxidants.)
The structure of kojic acid indicates a relatively simple route of metabolism much like dietary hexoses.
PMID:11259181 Burdock GA et al; Regul Toxicol Pharmacol 33 (1): 80-101 (2001)
The mechanism of action of kojic acid is well defined and it has been shown to act as a competitive and reversible inhibitor of animal and plant polyphenol oxidases, xanthine oxidase, and D- and some L-amino acid oxidases.

The activation of NF-kappaB induced by kojic acid, an inhibitor of tyrosinase for biosynthesis of melanin in melanocytes, was investigated in human transfectant HaCaT and SCC-13 cells. These two keratinocyte cell lines transfected with pNF-kappaB-SEAP-NPT plasmid were used to determine the activation of NF-kappaB. Transfectant cells release the secretory alkaline phosphatase (SEAP) as a transcription reporter in response to the NF-kappaB activity and contain the neomycin phosphotransferase (NPT) gene for the dominant selective marker of geneticin resistance. NF-kappaB activation was measured in the SEAP reporter gene assay using a fluorescence detection method. Kojic acid showed the inhibition of cellular NF-kappaB activity in both human keratinocyte transfectants. It could also downregulate the ultraviolet ray (UVR)-induced activation of NF-kappaB expression in transfectant HaCaT cells. Moreover, the inhibitory activity of kojic acid in transfectant HaCaT cells was found to be more potent than known antioxidants, e.g., vitamin C and N-acetyl-L-cysteine. These results indicate that kojic acid is a potential inhibitor of NF-kappaB activation in human keratinocytes, and suggest the hypothesis that NF-kappaB activation may be involved in kojic acid induced anti-melanogenic effect.
