The ultimate pure Vitamin C serum is here! HSGN, the brand that gave us the best Korean dupe of SkinCeuticals' Vitamin C, now brings us the ultimate version with concentrated, unrivalled benefits.

HSGN Pure 20% Vitamin C E Ferulic Acid Ampoule contains concentrated 20% L-Ascorbic Acid (Vitamin C) that adds reliable yet intense antioxidant benefits to the skin. It also contains Ethyl Ascorbic Acid, a stable form of Ascorbic Acid that is often praised as the most efficient and effective for Vitamin C. 

This one bottle of ampoule improves all signs of aging. Targeted benefits include improvements for:

• fine lines and wrinkles
• loss of firmness
• hyperpigmentation/discoloration
• acne prevention  

The Ferulic Acid in the formula maximizes the antioxidant and antibacterial benefits of Vitamin C, while Tocopherol (Vitamin E) neutralizes free radicals and replenishes skin lipids. This is a sensitive skin-approved Vitamin C serum that all skin types can benefit from.
