COSRX | Vitamin C 23 Serum

Pure form of vitamin C(also known as ascorbic acid and L-ascorbic acid), as a powerful antioxidant, neutralizes free radicals that cause oxidative stress on the skin, leading to premature skin aging. It is essential for collagen production in skin cells and helps maintain skin structure and delay signs of aging.

Due to oxidative stress, the skin looks grey and tired, and vitamin C helps it maintain a youthful and fresh appearance.

Pure vitamin C is the most biologically active form of vitamin C. It is known for its ability to stimulate and produce collagen and elastin through fibroblasts, thereby improving skin texture.

One of the main benefits of vitamin C is its powerful effect on all types of discolorations and uneven skin tone.Whether it's damage caused by unprotected and excessive sun exposure or those remaining after inflammatory processes, the mechanism of action is based on the inhibition of the tyrosinase enzyme, which is responsible for the excessive production of melanin (pigment). This visibly evens out skin tone, refreshes it, and gives it a healthy glow.

This formulation comes with a unique "dual" texture- non-greasy and non-comedogenic nourishing oils instantly soften and smooth the skin, making it ideal for the care of dry, mature skin.

After opening, keep refrigerated at 3-10˚C. Keeping it refrigerated ensures the freshness of vitamin C and slows down oxidation.

Use after cleansing, on dry facial skin, before moisturizing serums and/or cream. During the day, always use sun protection products, SPF 30 or higher.
