Ingredients

20% pure vitamin C, glutathione, ferulic acid, vitamin E, and adenosine support brighter-looking, more even, antioxidant-protected skin.

Vitamin C serums are widely used because they address several visible concerns at once. Pure ascorbic acid helps brighten dull skin, improve the look of post-acne marks and other discoloration, and provide antioxidant support against daily environmental stress. At a 20% concentration, the serum is positioned as a strong brightening treatment, which is why gradual introduction and daily sunscreen are especially important for comfortable use.

The supporting ingredients help strengthen that brightening role. Ferulic acid and vitamin E are often paired with vitamin C because they improve antioxidant performance and help the formula better defend against oxidative stress. Glutathione adds another radiance-focused layer by supporting a clearer, more luminous look. The lightweight milky texture matters too, because it makes a high-strength formula easier to spread and layer without feeling greasy. In practice, this serum works as a focused tone-correcting step for dullness, uneven pigmentation, and early visible aging. With steady use, it helps the skin look brighter, fresher, and more evenly radiant.
