Tetrahydrocurcumin

1. Whitening
Tetrahydrocurcumin can effectively inhibit tyrosinase and slow down the production of melanin, and is more effective than whitening agents such as kojic 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 whitening effects.
2. Antioxidant
Free radicals on the skin surface are generated due to ultraviolet rays, chemicals or other stress factors that catalyze skin aging. Tetrahydrocurcumin scavenges free radicals, thereby preventing their formation. In addition, tetrahydrocurcumin can also inhibit the proliferation of free radicals and inhibit the oxidation of fat. It can be added to the formula as a natural antioxidant to extend the shelf life of cosmetics.
3. Antibacterial and anti-inflammatory
Tetrahydrocurcumin has broad-spectrum anti-inflammatory and antibacterial effects, can repair skin inflammation and skin damage caused by UVB, and can more effectively relieve pain and swelling, and has a significant effect on treating mild burns, skin inflammation and acne scars.
