When it comes to whitening ingredients, everyone first thinks of traditional whitening raw materials such as arbutin, kojic acid, vitamin C, etc., and today's OEM cosmetics factory Xiaobian wants to talk about an overlooked whitening ingredient: tetrahydrocurcumin.
Neglected whitening ingredient, tetrahydrocurcumin [hydrophilic biology]
Derived from the rhizome of turmeric, a plant of the gingeraceae family, tetrahydrocurcumin is a naturally derived cosmetic whitening ingredient that, when at high purity, appears as a colorless and odorless white powder. INCI name: Turmeric extract. OEM OEM cosmetics factories are mostly used in high-end whitening cosmetics.
Tetrahydrocurcumin has the following skincare benefits:
1. Whitening
Tetrahydrocurcumin can effectively inhibit tyrosinase, slow down the production of melanin, and is more effective than whitening agents such as koranic acid, arbutin, and vitamin C. At the same time, the powerful antioxidant activity of tetrahydrocurcumin can also delay the production of melanin, thereby brightening the skin tone and achieving a whitening effect. In a foreign study randomized double-blind placebo-controlled trials on 50 subjects, researchers found that oem OEM cosmetics factories added 0.25% tetrahydrocurcumin to the whitening formula than 4% terephol (a skin decolorizer banned in cosmetics) cream more effective and safer.
2. Anti-inflammatory
Inflammation of the skin is a complex process, the anti-inflammatory effect of tetrahydrocurcumin is to inhibit the main inflammatory mediators such as: cyclooxygenase, lipoxygenase, interferon, transcription factors and nuclear transcription factors (NF-KB), etc., the inhibition of cyclooxygenase, collagenase, hyaluronidase, on the one hand, reduce skin inflammation including the formation of erythema, on the other hand, can also reduce wrinkles and maintain skin elasticity, anti-aging.
3. Antioxidant
Free radicals on the surface of the skin are produced by UV rays, chemicals or other stressors that catalyze skin aging. Tetrahydrocurcumin can clear and remove free radicals, thereby preventing the formation of free radicals. In addition, tetrahydrocurcumin can also inhibit the proliferation of free radicals and inhibit the oxidation of fat, oem OEM cosmetics factories add it as a natural antioxidant to the formula to extend the shelf life of cosmetics.
