Hydrating

Hydration is a fundamental part of healthy skincare, focusing on maintaining and restoring the skin’s water content. Well-hydrated skin appears plump, smooth and radiant, while dehydration can lead to dullness, tightness, fine lines and increased sensitivity.
Hydrating the skin can work through a fascinating mix of ingredients with different roles. Humectants like hyaluronic acid and glycerin act like water magnets, pulling water into the skin to instantly plump and smooth, while Natural Moisturizing Factors (NMFs)—such as urea, amino acids and sodium PCA—mimic the skin’s own hydration system, helping it hold onto water and stay balanced from within.
Adding humectants like hyaluronic acid to your routine will restore your skin's healthy glow, minimize fine lines, and provide a plumping effect.

Anti-Wrinkle

Anti-wrinkle skincare is focused on both preventing and visibly reducing the formation of lines by targeting the structural and dynamic causes of wrinkles within the skin. Fine lines and deeper wrinkles develop as collagen and elastin decline, cell turnover slows and repeated facial movements create creases that become etched over time. Advanced formulations address these mechanisms through a combination of elastin-stimulating actives, smoothing peptides that help relax the appearance of expression lines, and deeply hydrating ingredients that plump the skin from within. By reinforcing the skin’s architecture while softening surface contractions and improving elasticity, anti-wrinkle skincare delivers a visibly smoother complexion.

Plumping

Plumping involves using active ingredients to boost the production of key structural components like collagen, the dermal-epidermal junction and glycosaminoglycans (GAGs), giving your skin more volume and density. Collagen provides structural support and firmness, while the dermal-epidermal junction, a thin connective layer, ensures smooth, wrinkle-free skin by facilitating cell communication. GAGs, like hyaluronic acid, keep your skin hydrated and plump from within. By stimulating these components, active ingredients help restore your skin's plumpness and radiance.

Lifting

Lifting skincare focuses on restoring firmness and redefining facial contours by supporting the skin’s underlying structural integrity. As collagen, elastin, and cellular cohesion decline with age, the skin begins to lose density and sag. Advanced lifting formulations work to stimulate collagen synthesis, reinforce the extracellular matrix, and improve skin tension, helping to visibly elevate and tighten the skin. By enhancing structural support and promoting a more compact, resilient dermal network, these treatments create a firmer, more sculpted appearance, with features that appear lifted, refined, and more defined over time.

Anti-PIH (Post-Inflammatory Pigmentation)

Anti-PIH treatments are designed to target post-inflammatory hyperpigmentation—those lingering dark marks that appear after inflammation or skin injury, such as acne. These advanced formulations work on multiple levels: calming inflammation, accelerating skin repair, and promoting healthy regeneration while inhibiting excess melanin production. By combining growth factors with exfoliating actives, they stimulate cellular renewal and optimise the skin’s natural healing processes. This dual approach not only helps fade existing discoloration more effectively but also prevents new marks from forming.

Scar-Repairing

Anti-Scarring skincare targets the textured scars left by acne breakouts. These scars form due to inflammation disrupting collagen and elastin fibres leading to uneven healing and indented areas. Anti-Scarring actives harness growth factors and exfoliating actives to stimulate cell repair and regeneration, optimising the skin's healing process to reduce scar formation. They also effectively diminish older scars, improving overall skin texture and leaving you with a smoother complexion and significantly reduced scar visibility.

Regenerating

Regenerating skincare actively stimulates the formation of new, healthier skin, working in alignment with the skin’s innate renewal processes. Central to this are growth factors—effectively encouraging the development of new skin tissue. Peptides complement this by acting as targeted messengers guiding the skin to rebuild with greater strength and structural integrity. Stem cell–derived actives further support this environment by delivering protective and regenerative signals that optimize cellular function and renewal. While these mechanisms are synonymous with advanced anti-ageing—improving firmness, elasticity and overall skin quality—they are equally valuable in addressing scarring, as they promote tissue repair, accelerate regeneration and help restore a smoother, more even skin surface.

Biomimetic Placenta

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.

Collagen Organising Peptide

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.

Hyalufix™

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.

5 Hyaluronic Complex

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.

Allantoin

Allantoin is a natural plant derivative, widely used in skincare for its soothing, hydrating, softening and healing properties.
