Composition No. 1 Serum

Ultimate Optimising Serum

The definitive expression of the AUTEUR skincare philosophy, this high-active overnight treatment serum is engineered to repair and rejuvenate distressed, tired and damaged skin. Composition No. 1 brings together a range of over 40 active ingredients into one concentrated treatment - including perfluorocarbons, peptides, and antioxidants. Ingredients work together to enhance cellular regeneration and restore skin’s ability to achieve a more optimal function and healthier appearance. 

A symphony of five powerful peptides target specific cellular functions and rejuvenate fibroblast cells, increase collagen formation, reinforce the protective lipid barrier, and restore skin’s own production of Hyaluron - allowing it to maintain a higher level of hydration on its own.

Gold Pro-Collagen Complex activates the formation of new healthy collagen and enhances the bio-availability of peptides by up to 90x, amplifying the efficacy of active ingredients within the skin. 

A 10% concentration of AUTEUR Perfluorocomplex increases oxygen levels within the skin to speed up cellular metabolisms, enhance the production of collagen and elastin, eliminate toxins and repair damage. Skin is able to achieve a healthier state of equilibrium with more youthful cellular functions activated.

Hydration is restored through a combination of amino-acids, skin-identical lipids,  Hyaluronic Complex, and botanically-derived actives that deliver multiple molecular weights of moisture throughout all layers of the skin. Skin appears smoother and more voluminous while signs of dehydration including fine lines are minimised. 

Retinol and Lactic Acid work together to gently smooth and refine skin’s surface and texture, while antioxidants fight free-radical damage and guard against signs of photo-aging including spots, lines, wrinkles and pigmentation. 

Composition No. 1 is a complete regenerative solution designed to repair and restore skin to its optimal condition. 

Made in Germany.
