Dermatologist-Tested | Cruelty-Free | High-Concentration Formula

A high-potency brightening serum designed to revive dull, tired skin with a concentrated dose of 23% pure Vitamin C (Ascorbic Acid). This targeted treatment helps visibly fade hyperpigmentation, improve skin tone clarity, and support collagen production for a firmer, more radiant complexion.

To amplify the antioxidant effects and support skin resilience, the formula is enhanced with Tocopherol (Vitamin E) and Panthenol, which help calm and protect the skin barrier. Hydrating support comes from birch juice, known for its mineral-rich, soothing properties. The serum absorbs rapidly into the skin to deliver active ingredients deep within the dermal layers without residue or stickiness.
