COSRX | The Vitamin C 23 Serum


COSRX The Vitamin C 23 Serum contains a high concentration of ascorbic acid (23% of the most active and purest form of vitamin c) to fade acne scars, brighten the complexion and revitalize dull skin. Vitamin c helps to boost radiance and treat hyperpigmentation by blocking the synthesis of melanin caused by UV exposure. It will also help to promote collagen production, reversing the signs of aging and increasing skin's elasticity. The formula is hypoallergenic and can be used on sensitive skin. If you are just starting out with vitamin c, we recommend using it once every few days to start. If using in the morning, remember to apply SPF! 

Size: 20ml (comes with dropper)
