Enhanced with 0.5% ferulic acid and 0.1% vitamin E (tocopherol) to maximize vitamin C's antioxidant benefits. As a brightening functional cosmetic certified by the Ministry of Food and Drug Safety, it helps target dull skin tone and dark spots. The formula is designed with a pH below 4.0 to optimize vitamin C concentration for effective absorption into the skin.\u003c\/p\u003e\u003ch3\u003eAntioxidant Efficacy Confirmed Through Testing\u003c\/h3\u003e\u003cp\u003eThis product's antioxidant efficacy has been verified through in vitro antioxidant performance evaluation conducted by OATC testing laboratory.

This reflects research findings that absorption actually decreases when concentration exceeds 20%.\u003c\/p\u003e\u003ch3\u003eKeeping Oxidation-Prone Vitamin C Fresh\u003c\/h3\u003e\u003cp\u003ePure vitamin C is highly susceptible to oxidation from light, heat, and oxygen. To minimize oxygen exposure, the formula is divided into two 15ml brown glass bottles.

Recommended for those starting to notice melasma and hyperpigmentation, concerned about loss of skin elasticity, or ready to begin a serious anti-aging regimen.
