AC-VCE
AC-VCE is a multifunctional vitamin C derivative and one of the most stable ascorbic acid derivatives known. In addition to its significant hydrophilic property (water solubility), it is also soluble in fats or lipids, enhancing its ability to penetrate the skin's lipid barrier and reach deeper skin layers. The addition of an ethyl group to ascorbic acid ensures prolonged stability and efficacy in cosmetic formulations, thereby improving efficacy. It promotes collagen synthesis, scavenges free radicals, and protects the skin from both intrinsic DNA damage and extrinsic damage caused by UV radiation, blue light, and air pollution. Its recommended applications include skin whitening, anti-aging, and sun protection.

FAQ
Q1: How to achieve whitening and lightening?
A1:Triple pathway:
1 Inhibits tyrosinase and reduces melanin synthesis
2 Reduces dopaquinone and blocks oxidative polymerisation
3 Accelerates keratin metabolism and lightens existing pigments
Q2: What is the optimal concentration of AC-VCE?
A2: The usage concentration of AC-VCE in skincare products typically ranges from 0.1% to 3%. A concentration of 2% AC-VCE has been shown to improve dark spots on sun-damaged and dull skin by inhibiting melanin formation. Concentrations exceeding 5% may be utilized depending on the desired efficacy, with studies confirming that concentrations up to 30% demonstrate no irritation on human skin samples.
