Description

This highly concentrated vitamin C serum with 23% pure ascorbic acid gives you a more radiant, even-looking complexion and a firmer-feeling skin. The formula combines vitamin C with Super Vitamin E (tocotrienols) and glutathione for intensive antioxidant care.

What's inside

  • Ascorbic acid (23%): pure vitamin C for a fresh, clear-looking complexion
  • Tocotrienols and glutathione: add to the antioxidant care
  • Hyaluronic acid and panthenol: provide moisture and support the skin barrier

The serum cares for skin with discolouration and a dull complexion. The two-layer formula with a layer of oil on top protects the vitamin C from oxidation and leaves a nourishing finish.

The serum is ideal for you if you already have experience with vitamin C skincare.

Application
In the evening, after cleansing and toning, apply 2–3 drops to your face and gently pat in. To begin with, use every other day, as high-dose vitamin C can cause a slight tingling at first. Avoid the eye area. Use sun protection the following day. Close the bottle tightly after use.
