Radiance Duo – 2-step

Step 1 — 10% Vitamin C & Astaxanthin Concentrated Serum

Gently cleanse and dry your skin. Apply a few drops of serum to the face and neck, massaging gently with your fingertips to help the product absorb. Avoid the eye area. Use in the morning and/or evening, before applying your moisturiser.

Step 2 — Hyaluronic Acid & Polyglutamic Acid Cream

Take a small amount of cream and apply it all over your face and neck, massaging until fully absorbed. Use in the morning and/or evening, as the final step in your skincare routine.

Tip: Our Vitamin C skincare products are highly concentrated and should be used separately. The Hyaluronic Acid & Polyglutamic Acid Cream, which contains no vitamin C, layers perfectly over the serum.

10% Vitamin C & Astaxanthin Concentrated Serum

With a high concentration of 10% stabilised, naturally sourced Vitamin C, this brightening serum fades dark spots, evens out a dull complexion and boosts cell renewal. Astaxanthin, extracted from the microalgae Haematococcus pluvialis, offers exceptional antioxidant power — 100 times greater than that of vitamin E — to protect the skin from the effects of the sun, pollution and tobacco. Its light texture absorbs instantly without leaving a greasy film.
