Resveratrol is a powerful antioxidant naturally found in red grapes. It contains high levels of polyphenols that help protect the skin from UV damage and environmental stressors by neutralising free radicals. By safeguarding cell DNA, it reduces inflammation and accelerates the skin's natural repair processes. Additionally, resveratrol helps to inhibit glycation, the process in which excess sugars bind to collagen and elastin, leading to stiffness and loss of elasticity. Through its antioxidant and anti-glycation actions, resveratrol effectively reduces wrinkles, evens out skin tone, and improves firmness, resulting in a brighter and more youthful complexion.

Cyclopeptide-5 is a biomimetic peptide that mimics natural cellular communication to enhance skin repair and regeneration functions. it works by mimicking the natural signalling processes within skin cells, which are essential for repair and regeneration. When applied topically, it penetrates into the skin and interacts with receptors on cell surfaces, triggering mechanisms that enhance collagen and elastin production. These proteins are crucial for maintaining skin structure, firmness, and elasticity. By protecting collagen and elastin from degradation caused by ageing and UV exposure, Cyclopeptide-5 helps to preserve skin density and smoothness. It also supports the restructuring of the extracellular matrix, which can reduce the appearance of wrinkles, tighten facial contours, and restore youthful volume to the skin. Overall, Cyclopeptide-5 promotes a more resilient, rejuvenated complexion with improved elasticity and a reduction in visible signs of ageing.

SYN®-AKE is a synthetic Tripeptide (a small molecule made up of three amino acids) designed to mimic the muscle-relaxing effects of snake venom. It works by inhibiting facial muscle contractions, which are responsible for forming expression lines like those around the eyes, forehead, and mouth. Similar to injectable treatments, SYN®-AKE smooths wrinkles and provides a noticeable lifting effect, particularly on sagging skin. This peptide is revolutionary in skincare for its ability to reduce the appearance of fine lines and wrinkles without the need for invasive procedures, helping to achieve a more youthful and rejuvenated complexion.

Auteur's supercharged 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.

Auteur 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 (70-1,000 kDa?), 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 (<70 kDa), 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? (<10 kDa), 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.

Bioplasma™ FA is a proprietary blend of Phytoplankton Extract and Arginine Ferulate aimed at detoxifying skin cells and protecting against environmental stressors. By effectively reducing Trans epidermal Water Loss (TEWL), it strengthens the skin's protective barrier, retains moisture, and diminishes the depth of wrinkles.

Saccharide Isomerate, also known as PentavitinÆ, is a carbohydrate complex derived from plants that closely resembles those found in human skin. It serves multiple functions in skincare: first, it acts as a prebiotic, supporting a healthy balance of microorganisms on the skin's surface, which is crucial for maintaining skin health.

Secondly, Saccharide Isomerate functions as a powerful humectant. This means it attracts moisture from the environment and binds it to the skin, acting like a "water magnet." This ability helps to deeply hydrate the skin, making it appear plump, smooth, and intensely moisturised.

Studies have shown that Saccharide Isomerate can increase skin hydration levels for up to 72 hours after application, making it an effective ingredient for providing long-lasting hydration and maintaining skin moisture balance.

Complex of Peach Tree Leaf, Apple & Raspberry Extract also known as is rich in Vitamin C & Alpha Hydroxy Acids, combining anti-pigmentation activity with lightening and exfoliating actions, to combat sun and age pigmentation. The marriage of these ingredients not only results in a more even complexion where future pigmentation is reduced, but existing pigmentation is lightened.

Arginine is a naturally occurring amino acid found in the skin that facilitates healing and repair processes. It acts as a hydrating and collagen-boosting active, supporting collagen synthesis for firmer, plumper skin. In addition, Arginine helps to protect against glycation, a process in which sugars bind to collagen and elastin fibres, causing them to stiffen and lose elasticity. Its antioxidant properties further help neutralise free radicals, reducing oxidative and glycation-related stress to effectively combat signs of premature ageing and maintain a smoother, more resilient complexion.

Ectoin, alternatively spelled "ectoine," is a derivative of amino acids—organic compounds that serve as the fundamental building blocks of proteins and peptides. It functions to protect cellular structures in organisms exposed to extreme environmental conditions such as high salinity, extreme pressure, and severe temperature fluctuations. It achieves this by stabilising critical biomolecules, including enzymes, proteins, and nucleic acids. Ectoin forms a protective barrier around the skin, shielding it from environmental stressors such as ultraviolet (UVA) radiation and pollution. Furthermore, ectoin mitigates transepidermal water loss (TEWL) by reducing stress on the stratum corneum, the outermost layer of the skin, even in arid and challenging environments. Ectoin provides several scientifically backed benefits for skin health, including: - Its ability to reduce TEWL contributes to softer, smoother skin by maintaining optimal moisture levels and supporting a balanced skin microbiome. - It helps protect against UVA-induced damage, reducing hyperpigmentation and photoaging. - Ectoin alleviates skin sensitivity and stress, making it suitable for irritated or compromised skin.
