SYNÆ-HYCANAnti-Wrinkle · Hydrating · Plumping
SYNÆ-HYCAN is a cutting-edge, low molecular weight peptide formulation designed to diminish the signs of ageing by significantly boosting the skin's natural production of collagen and hyaluronic acid. This advanced peptide technology penetrates deeply into the skin, delivering rapid and visible anti-ageing benefits. By increasing collagen and hyaluronic acid levels, SYNÆ-HYCAN enhances skin hydration, plumps up the skin, and effectively diminishes wrinkles in rejuvenated appearance.SYN®-AKEInjectable Effect
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.Encapsulated RetinolAnti-Wrinkle · Plumping · Anti-Pigmentation
Encapsulated Retinol is a stabilised form of Vitamin A that is released gradually when massaged into the skin, reducing irritation and dryness typically associated with retinol use. Retinol is one of the most well proven skincare actives for treating blemishes, pigmentation, and signs of ageing. It works by speeding up cell turnover, stimulating collagen and elastin production, supporting DNA repair and regulating melanin (pigment) and sebum (oil) overproduction. This result is a smoother, firmer, more even complexion.Retinol (Vitamin A)Anti-Wrinkle · Plumping · Anti-Pigmentation
Vitamin A also known as retinol is one of the most well proven skincare actives for treating blemishes, pigmentation, and signs of ageing. It works by speeding up cell turnover, stimulating collagen and elastin production, supporting DNA repair and regulating melanin (pigment) and sebum (oil) overproduction. This results in a smoother, firmer, more even complexion.5 Hyaluronic ComplexAnti-Wrinkle · Hydrating · Plumping
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.Saccharide Isomerate (PENTAVITIN)Hydrating · Reduces Trans Epidermal Water Loss · Microbiome Balancing
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.EctoinHydrating · Reduces Trans Epidermal Water Loss · Microbiome Balancing
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.Beta-GlucanAnti-Wrinkle · Hydrating · Plumping
Beta-glucan, derived from yeast, is a chain of sugar molecule known for its humectant (hydrating), collagen-boosting, and anti-inflammatory properties. It strengthens the skin barrier, supports a balanced microbiome, and enhances resilience against environmental aggressors. Beta-glucan deeply hydrates the skin, diminishes wrinkles, and provides a soothing effect, making a great multi-benefit ingredient for all skin types.Lactobacillus FermentMicrobiome Balancing · Anti-Inflammatory · Balancing the Skin pH
Lactobacillus Ferment, a probiotic derived from the fermentation of Lactobacillus bacteria that focuses on microbiome balancing. A balanced microbiome is crucial for healthy skin as it strengthens the skin's barrier, reduces inflammation, and improves hydration, resulting in healthier and more resilient skin. It also helps maintain optimal pH levels and protects against infections.Alpha-Hydroxy AcidsBrightening · Sebum Regulating · Chemical Exfoliation
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.Ceramides ComplexReduces Trans Epidermal Water Loss · Skin Barrier Strengthening
Ceramides are lipids naturally found in our skin barrier. They play an essential role in preventing Trans epidermal Water Loss (TEWL) which is the loss of moisture through the skin, by restoring and maintaining healthy the skin's barrier function. Ceramides also enhance the skin's natural protection against environmental aggressors and irritants, helping to keep skin balanced and calm.Hydrolite® 5 GreenHydrating · Plumping · Active Delivery
HydroliteÆ 5, also known as Pentylene Glycol, is a multi-purpose ingredient that hydrates and strengthens the skin while enhancing the performance of the other active in the formula to ensure skin receives maximised benefits.10% PerfluorocomplexBrightening
The 10% Perfluorocomplex features three powerful oxygen carriers that accelerate oxygen delivery to your skin. This boost in oxygen energises your cells, enhancing collagen and elastin production, removing toxins, and repairing cellular damage. Plus, the increased oxygen levels brighten your complexion, giving your skin a radiant, luminous glow.Golden CollagenineAnti-Wrinkle · Firming & Lifting · Active Delivery
Golden Collagenine combines a collagen-boosting peptide with gold and platinum carrier particles to deliver actives directly to the receptors of collagen producing cells, thereby enhancing its activity. This unique formula creates channels within the skin that allow deeper penetration of ingredients, increasing the bioavailability of actives by up to 90x. As a result, it significantly reduces wrinkles and restores youthful firmness to the skin.Cyclopeptide-5Anti-Wrinkle · Plumping · Firming & Lifting
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.
