The whitening and freckle removing function of Arbutin

Arbutin is can be naturally extracted from plants such as bearberry and synthesized by chemical method. Synthesized Arbutin is currently one of the most widely used hypopigmenting agents in cosmetics. Arbutin can also moisten the skin which looks very lightening, so arbutin is used skin lightening and whitening agents in the cosmetics.

Arbutin includes Alpha-Arbutin and Beta-Arbutin. For the product detailed information, you can visit the link: https://yrchemspec.goodao.net/alpha-arbutin-product/

Causes of pigmentation:

The skin colour is determined by the interaction of different colorants. The brown coloration results from the pigments eumelanin and phaeomelanin, which are produced in special epidermal cells called melanocytes. The enzyme tyrosinase, usually present in an inactive form, is formed in these melanocytes. Its activation by UV light triggers off melanogenesis, a complex series of enzymatic chemical reactions which finally lead to the formation of melanins, leading to undesirable discolorations on the surface of skin that typically manifests as age spots, melasma or freckles.

Mechanism of Action:
Arbutin is glycosylated hydroquinone that comes in 2 forms, the Alpha-Arbutin and the Beta-Arbutin. Arbutins are considered to be the ideal skin lightening agent as it assists in the blocking of epidermal melanin biosynthesis. It helps to block epidermal melanin biosynthesis by inhibiting enzymatic oxidation of Tyrosine and Dopa.

Alpha-Arbutin has been proven to have superior results, even when compared to its chemically-similar molecules, hydroquinone and beta-arbutin. In addition to higher efficacy, it also boasts a better safety profile compared to hydroquinone, and is more stable when compared to beta-arbutin. These characteristics make it the go-to active for lightening of complexion and minimization of dark spots on the skin.

Hydroquinone vs Alpha Arbutin
Hydroquinone has long been considered the gold standard for the treatment of hyperpigmentation. While clinical studies report excellent depigmentation responses induced by 2% hydroquinone, it has also been shown to cause chronic adverse effects. These include exogenous ochronosis, cataract, pigmented colloid milia, sclera, and nail pigmentation, loss of elasticity of the skin, impaired wound healing and exuding an offensive fish odour. Hydroquinone can also cause DNA damage. These adverse effects limits the usage of hydroquinone.

Alpha-Arbutin has been proven to effect a superior lightening effect without the toxicity and irritations associated with hydroquinone.
