3-O-Ethyl Ascorbic Acid is a stable, vitamin C-derived agent for skin whitening.
Ethyl Ascorbic Acid is one kind of Vitamin C ramification, which can dissolve both oil base and water base. It can easy penetrate horniness to reach the dermis. Then the enzyme decompounds them and releases the Vitamin C. Which enhance the usage of VC and more stable than the general VC.
Vitamin C derivatives (ethyl ether) is not only very stable chemicalperformance but also easily into the skin enzymeDecomposition of C play the role of peacekeeping.
3-O-ethyl Ascorbic Acid is an effective melanin inhibitor, reducing tyrosinase and TRP-2 protein expression, stimulating collagen synthesis, protecting DNA and lightening skin, all while exhibiting excellent stability.
It is the best derivative consisting of vitamin C with an ethyl group bound to the third carbon position.
It is metabolized in the same way as VC in human body after entering the skin, which helps VC play a better role.
It is very convenient for formulation applications in gels, serums, lotions, creams and other whitening, anti-aging and other skin care products.
