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.

X50® Myocept PeptideInjectable Effect · Plumping · Firming & Lifting
X50® Myocept Peptide combines a Neuropeptide with a complex of encapsulated Lactic and Glycolic Acids. The Neuropeptide works by inhibiting facial muscle contractions, thereby reducing the appearance of expression lines and wrinkles. Meanwhile, Glycolic and Lactic Acids gently exfoliate the skin, promoting brightness and stimulating collagen production.
The delivery system used ensures that these active ingredients reach their target areas effectively, enhancing their overall effectiveness. By combining these actions, X50® Myocept Peptide aims to provide comprehensive benefits such as plumping, tightening, and smoothing wrinkles for a more youthful and revitalized complexion.Alpha-Hydroxy AcidsChemical Exfoliation · Pore Decongesting · Sebum Regulating
Alpha-Hydroxy Acids are a chemical exfoliant which exfoliate the top layers of the skin, offering a variety of benefits. They are mostly derived from plant-based sources. Some of the most common AHAs are Glycolic Acid, Lactic Acid, Citric Acid, Mandelic Acid and Malic Acid. Depending on the type of AHA, they can reduce dullness, even skin tone, reduce pigmentation, tighten pores, stimulate collagen production, hydrate the skin and offer antioxidant protection. AHAs are generally less irritating and drying to the skin as they are water-soluble.Willow Bark ExtractChemical Exfoliation · Pore Decongesting · Sebum Regulating
Willow Bark Extract contains a compound called salicin, which enzymatically converts into salicylic acid (BHA) when applied to the skin. Salicylic acid is a beta hydroxy acid (BHA) known for its exfoliating properties. It works by penetrating into the pores and exfoliating the dead skin cells and debris that can clog them, thus helping to prevent acne and improve skin texture. Additionally, Willow Bark Extract has anti-inflammatory and antimicrobial properties, which further contribute to reducing inflammation, calming the skin, and regulating sebum (oil) production. Overall, it helps to refine the skin's appearance, reduce blemishes, and minimize the appearance of pores.5 Hyaluronic ComplexPlumping · Hydrating · Anti-Wrinkle
Hyaluronic Complex includes 5 different molecular weights of Hyalurons ranging from ultra-low too high for and instant boost of hydration, increased skin firmness and elasticity and long-lasting plumping results.
Hyaluronic Complex includes:
Cross-linked Hyaluronic Acid or Sodium Hyaluronate Crosspolymer, forms a three-dimensional mesh-like structure on the skin's surface. This unique structure acts as a breathable hydration barrier, helping to increase water retention by blocking trans epidermal water loss (TEWL). Cross-linked hyaluronic acid also has wrinkle-filling and skin-softening effect.
Medium Molecular Weight Hyaluronic Acid or Sodium Acetylated Hyaluronate, occupies a unique position between high and low molecular weight hyaluronic acids, boosting skin hydration in the middle layers of the skin. It complements and enhances hydrating plumping results from famous Low and High Hyaluronic Acids, giving the skin even more suppleness and volume. It's in particularly good for those who have hollow faces due to density loss.
Low Molecular Weight Hyaluronic Acid or Sodium Hyaluronate, is a salt for derived from naturally occurring hyaluronic acid. Sodium hyaluronate has a low molecular size which allows it to penetrate the skin deeper and more effectively. Sodium hyaluronate has superior hydrating and skin-plumping benefits. Increased skin hydration also contributes to efficient desquamation, supporting the skin's natural renewal cycle.
Ultra-Low Molecular Weight or Hydrolyzed Hyaluronic Acid penetrates the skin the faster and the deepest compared to other forms. This provide ultra hydrating and plumping results. Additionally it can enhance collagen and elastin synthesis by stimulating fibroblast activity, resulting in firmer, denser and smoother looking skin.X50® Skin BarrierSkin Barrier Strengthening
X50® Skin Barrier utilises a specialised delivery system (drone system) to transport two peptides directly to keratinocytes, which are cells crucial for maintaining the skin's barrier function. These peptides stimulate the production of key proteins like keratin, filaggrin, and loricrin. These proteins play a vital role in forming a strong and resilient skin barrier.
As we age, our skin's ability to produce these proteins decreases, leading to a weakened barrier and increased water loss through the skin. By boosting the synthesis of these proteins, X50® Skin Barrier helps to restore and strengthen the skin's protective barrier. This results in improved hydration levels and better protection against environmental factors such as pollution and UV radiation, which can damage the skin and accelerate ageing. Overall, X50® Skin Barrier supports healthier, more resilient skin by enhancing barrier function and promoting skin renewal.Kahai OilPlumping · Firming & Lifting · Brightening
Kahai Oil, also known as Cacay Oil, offers versatile benefits including anti-ageing, nourishment, and protection for the skin. Kahai Oil works through a combination of its rich components: The Vitamins E and A in Kahai Oil act as antioxidants, protecting skin cells from free radical damage and environmental stressors, which helps to prevent premature ageing. Vitamin A (Retinol) supports skin cell renewal and repair, reducing the appearance of fine lines and wrinkles by promoting the production of new, healthy skin cells. Omega-3 and Omega-6 Fatty Acids are essential fatty acids that strengthen the skin barrier, improve hydration, and reduce inflammation, leading to healthier, more resilient skin. Together, these components nourish, protect, and rejuvenate the skin, resulting in a smoother, more youthful complexion.Jojoba OilAnti-Inflammatory · Nourishing
Jojoba Oil has a similar oil composition to human sebum (oil) This similarity allows it to replenish the hydro-lipidic film and regulate sebum overproduction, without clogging pores or creating a greasy feel. When applied to the skin, Jojoba Oil can trick the skin into thinking it has produced enough oil, thereby reducing excessive oil production. Additionally, it has anti-inflammatory and antibacterial properties, making it ideal for congested, oily, and blemish-prone skin.
