Definitive Optimising Mask
Benefits
The AUTEUR Definitive Optimising Mask is a high-performance treatment designed to resurface, refine, and regenerate the skin, delivering immediate brightness, visible tightening, and long-term improvement in tone, texture, and elasticity. Combining advanced peptide technology with exfoliating acids and deep hydration, this multi-functional formula targets both the surface and structural causes of ageing for a smoother, firmer, and more radiant complexion.
At the core of the formula is X50® Myocept Peptide, a targeted neuropeptide delivery system that helps relax micro-contractions within the skin, visibly softening expression lines and wrinkles. This is supported by a complex of Palmitoyl peptides (Palmitoyl Hexapeptide-52, Heptapeptide-18, Heptapeptide-27, Octapeptide-24, Oligopeptide-78), which stimulate collagen production and improve skin density, resulting in enhanced firmness and structural integrity.
A sophisticated exfoliating system combines Phytic Acid, Lactic Acid/Glycolic Acid Copolymer, and Salix Alba (Willow) Bark Extract to gently remove dead skin cells, refine pores, and accelerate cell turnover. This process helps to smooth texture, reduce pigmentation, and reveal a brighter, more even complexion while supporting ongoing skin renewal.
The formula is further enhanced by a multi-molecular Hyaluronic Complex (Sodium Hyaluronate, Sodium Acetylated Hyaluronate, Hydrolyzed Sodium Hyaluronate, Crosspolymer), which delivers hydration at multiple levels of the skin, creating an immediate plumping effect while reinforcing long-term moisture retention. Tremella Fuciformis Extract (Snow Mushroom) amplifies this effect by acting as a natural humectant, enhancing skin suppleness and elasticity.
Nourishing lipids and barrier-repairing ingredients—including Caryodendron Orinocense (Kahai) Oil, Jojoba Oil, Shea Butter, Squalane, and Ceramide NP—work to strengthen the skin barrier, reduce transepidermal water loss, and improve resilience. Panthenol and Aloe Vera provide soothing and regenerative benefits, supporting skin recovery and comfort following exfoliation.
A vitamin-rich complex featuring Mangifera Indica (Mango) Seed Butter and Tocopherol (Vitamin E) delivers antioxidant protection while enhancing radiance and skin smoothness, helping to protect against environmental stress and premature ageing.
Together, these clinically advanced actives deliver a comprehensive approach to skin optimisation—exfoliating, hydrating, firming, and regenerating simultaneously.
