Function of Ethyl Ascorbic Acid / 3-O-ethyl ascorbic acid
Ethyl Ascorbic Acid / 3-O-ethyl ascorbic acid is a new generation of VC derivative that provides superb whitening effects, also serves as a potent anti-aging active that boosts collagen synthesis and protects skin from DNA damage. It exhibits strong inhibition effect on melanogenesis, reduces dark spots and age spots, fights photoaging by interfering with inflammatory cytokines, such as IL-6, and reverse ROS production to achieve free radical scavenging purpose.
1. Ethyl Ascorbic Acid can blocks melanin formation, through Cu2 + acting on tyrosinase inhibits its activity;
2. Ethyl Ascorbic Acid has effect for whitening and freckling (usually when 2% added);
3. Ethyl Ascorbic Acid can improve the dullness of the skin, and give the skin elasticity;
4. Ethyl Ascorbic Acid can repair skin cell activity and promote collagen production.can blocks melanin formation, through Cu2 + acting on tyrosinase inhibits its activity.
Application of Ethyl Ascorbic Acid / 3-O-ethyl ascorbic acid
1. Ethyl Ascorbic Acid applied in cosmetic filed, it has effect for whitening and freckling (usually when 2% added);
2. Ethyl Ascorbic Acid can improve the dullness of the skin, and give the skin elasticity.
