Using a high concentration of vi-ta-min C may also cause irritation depending on your skin type. The Ordinary describes this effect as a tingling but non-irritating sensation.

If your skin cannot tolerate a higher amount of L-Ascorbic Acid, you can try a lower concentration of L-Ascorbic Acid, set an L-Ascorbic Acid sản phẩm with another serum or cream, or start out with a vitamin C derivative.
