Alfa Arbutin is a pure biosynthetic and hydro soluble active ingredient which activates skin lightening and unifies any skin type by way of blocking the synthesis of melanin pigments which inhibits the enzymatic oxidation of tyrosine and the DOPA.. The experimental conditions were [E]0 = 30 nM and [L-dopa]0 = 0.5 mM. Total oxygen consumption test (L-dopa). showed that tyrosinase can hydroxylate arbutin, generating 3,4-dihydroxphenyl-o--D-glucopyranoside in the presence of catalytic amounts of L-dopa [27,28]. In this work, we demonstrate that the oxy form of tyrosinase (oxytyrosinase) hydroxylates and -arbutin in ortho position of the phenolic hydroxyl group, giving rise to a complex formed by met-tyrosinase with the hydroxylated or -arbutin. Include your email address to get a message when this question is answered. Structurally, ALPHA-ARBUTIN (IUPAC name: 4-hydroxyphenyl--D-glucopyranoside) is an . Kubo et al. If youre going to use the popular combination, you may be wondering between arbutin and niacinamide, which first. This cream can be used on areas all over your body, such as the inner thigh area or under the arms. This complex could evolve in two ways: by oxidizing the originated o-diphenol to o-quinone and deoxy-tyrosinase, or by delivering the o-diphenol and met-tyrosinase to the medium, which would produce the self-activation of the system.

Antioxidants help fight free-radicals. Therefore, although and -arbutin are used in cosmetics, their action mechanism needs to be fully understood. Applied topically, it inhibits tyrosinase and thus prevents the formation of melanin. "This results in less pigment, dark spots and skin lightening." Some compounds with resorcinol structure, such as 4-hexylresorcinol [5], 4-n-butylresorcinol [6] or oxyresveratrol [7], and others such as ellagic acid [8], are used as inhibitors of the enzyme in cosmetics and pharmaceutical industries [2]. Inhibition of monophenolase activity by arbutins. Alpha Arbutin is a serum that reduces spots and hyperpigmentation and it is well known for just that. Action of tyrosinase on -arbutin in the presence of MBTH. By inhibiting tyrosinase activity, alpha-arbutin is known to reduce melanin production in the skin. 699.00 594.00 Save: 105.00 15% Off. It can also produce hyperpigmentation disorders such as ephelide, freckles, solar lentigines and melasma [2], which are treated with inhibitors of tyrosinase [24]. In fact, it has been said that -arbutin does not inhibit mushroom tyrosinase, but it is more potent than -arbutin as an inhibitor of tyrosinase from B16 mouse melanoma [23].
