Active ingredients
Retinol (Vitamin A)Firming & Lifting · Anti-Wrinkle · Renewing
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.Encapsulated RetinolFirming & Lifting · Anti-Wrinkle · Renewing
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.BakuchiolFirming & Lifting · Anti-Wrinkle · Renewing
Bakuchiol is a clinically proven, natural alternative to retinol, studies have demonstrated that Bakuchiol offers retinol-like benefits such as boosting collagen production, brightening and promoting skin cell renewal, resulting in firmer, smoother, and more event toned complexion. Unlike retinol, Bakuchiol is non-irritating and non-photo-sensitising, thus safe to use every day, morning and evening, without the usual side effects of retinol. Moreover, Bakuchiol provides anti-inflammatory, antioxidant, and anti-bacterial properties that help soothe, protect, and minimise blemishes.Alpha-Hydroxy AcidsSebum Regulating · Brightening · 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.5 Hyaluronic ComplexAnti-Wrinkle · Plumping · Hydrating
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.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.Bioplasma™ FAAntioxidant · Reduces Trans Epidermal Water Loss · Detoxifying
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.Kahai OilFirming & Lifting · Anti-Wrinkle · Renewing
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.
