Definitive Hyaluron Activator Serum
Benefits
The AUTEUR Definitive Hyaluron Activator Serum is a high-performance hydration treatment designed to restore optimal moisture levels, strengthen the skin barrier, and visibly improve smoothness, elasticity, and radiance. Engineered with advanced molecular hydration technology, this formula works across multiple layers of the skin to deliver both immediate plumping and long-term skin resilience.
A multi-weight hyaluronic complex — featuring Sodium Hyaluronate alongside advanced hydration actives—penetrates at different depths to attract and retain moisture, instantly smoothing fine lines while reinforcing long-term hydration. Collagen-supporting peptides help to improve firmness and elasticity, enhancing the skin’s structural integrity and promoting a more refined, supple appearance.
Niacinamide works to strengthen the skin barrier, refine texture, and improve overall tone, while Panthenol soothes and supports skin repair. Antioxidant ingredients help defend against environmental stressors, reducing signs of fatigue and supporting a healthier, more luminous complexion.
Glycerin and additional humectants draw moisture into the skin, while barrier-supporting lipids help to prevent transepidermal water loss, ensuring lasting hydration and comfort. The result is skin that feels deeply hydrated, visibly smoother, and more resilient.
Together, these precisely selected actives deliver a comprehensive approach to hydration and skin performance — plumping, strengthening and revitalising the skin.

Ingredients
Collagen Organising PeptidePlumping · Firming & Lifting · Regenerating
Collagen Organising Peptide, also known as Decorinyl, replicates the function of Decorin, a protein involved in regulating fibrillogenesis, which is essential for collagen formation. By mimicking, Decorinyl enhances the organisation and quality of collagen fibres in the skin. Using a liposomal delivery system (a method of transporting active skincare ingredients to enhance their penetration for improved efficacy) Decorinyl penetrates deeply into the skin's lower layers, ensuring rapid and efficient results. This process helps improve skin structure and firmness, promoting a smoother and more youthful appearance.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.Biomimetic PeptidePlumping · Firming & Lifting · Regenerating
Biomimetic Placenta contains key Growth Factors similar to those in the human placenta, aiding in cell growth and skin regeneration. This helps heal and reduce post-acne hyperpigmentation (PIH) and scarring. Additionally, it boosts collagen and elastin production, enhancing skin elasticity and firmness while reducing fine lines and wrinkles.Hyalufix™Plumping · Hydrating · Anti-Wrinkle
Hyalufixô, also known as Galanga Leaf Extract, is a powerful active ingredient that stimulates fibroblasts in the skin to enhance the production of natural Hyaluronic Acid. This promotes hydration, plumpness, and elasticity of the skin. Hyaluronic Acid is naturally produced in the deeper layers of the skin, where it helps maintain skin density and structural integrity. It also acts as a hydration reservoir, nourishing the upper layers of the skin and contributing to a smooth and supple complexion. This active ingredient is important because it supports the skin's moisture barrier and helps maintain its youthful appearance by boosting natural hydration levels and skin elasticity.Lactic AcidHydrating · Chemical Exfoliation · Pore Decongesting
A gentle yet highly effective alpha hydroxy acid that exfoliates while replenishing hydration. Naturally found within the skin's Natural Moisturising Factor (NMF), Lactic Acid refines rough texture, enhances radiance and improves moisture retention, revealing softer, smoother and more luminous skin with exceptional comfort.
