Powerful-Strength Line-Reducing Concentrate, Kiehl's Original Vitamin C Serum

This facial serum contains 10.5% Vitamin C (L-ascorbic acid), the maximum recommended percentage of vitamin C for sensitive skin, along with 2% Ascorbyl Glucoside (Vitamin Cg) and fragmented hyaluronic acid, which reduces roughness and minimizes the appearance of deep wrinkles through deep hydration.

It can be used day and night, avoiding the eye area. The feeling of softness and radiance is immediate, and its antioxidant action mitigates the harmful effects of free radicals, stimulating the production of collagen and elastin.

  • Dermatologically tested, suitable for sensitive skin

Main Ingredients

  • Vitamin C 10.5% (L-ascorbic acid), an antioxidant that improves the appearance of aging
  • Vitamin Cg 2% (ascorbyl glucoside), a vitamin C derivative that is activated in the upper layers of the skin
  • Fragmented hyaluronic acid deeply hydrates and minimizes wrinkles
How to use:
  1. Apply morning and/or evening before your usual treatment cream.
  2. Avoid the eye area.

Incredible!
This serum is incredible; it leaves my skin extremely soft and smooth. I apply it at night. I have sensitive skin, and it works perfectly for me; it doesn’t cause any reaction.
