Isntree Hyper Vitamin C 23 Serum 20ml

Description

This high-strength vitamin C serum features 23% pure ascorbic acid in a lightweight formula designed to enhance the appearance of radiance and clarity. Combined with a stabilized vitamin C derivative (ethyl ascorbyl ether) and antioxidant-rich ingredients, the serum helps improve the look of dull or uneven-looking skin over time.

Birch sap contributes lightweight hydration, while panthenol and tocopherol (vitamin E) help keep skin feeling comfortable and well-conditioned.
