Clarifying and Refinishing Treatment

A high-active, brightening retinol serum for overnight use that reinvigorates the skin’s natural functions and appearance from within to deliver visibly renewed, smoother skin.

A potent combination of both Encapsulated Retinol (Vitamin A) and Bakuchiol work in synchrony to stimulate cellular turnover, reducing the appearance of hyperpigmentation and lines while restoring radiance. Skin soothing ceramides and AUTEUR’s Hyaluronic Complex protect the lipid barrier and restore hydration throughout all layers of the skin while keeping skin free of irritation.



Lactic and Glycolic Acids gently resurface skin, improving texture. Active Ceramide Complex forms a protective barrier to reduce transepidermal water loss, capturing and binding water that is necessary for the skin to obtain supple, healthy hydration. A rich blend of antioxidants including Squalane, BIOPLASMA FA and Green Tea scavenge free radicals caused by UV and environmental damage. Skin appears brighter while cellular energy is restored, and skin is able to maintain its optimal function and appearance.

Fragrance free.

Made in Germany.
