Hydrate & Brighten Intense Serum

Hyaluronic acid is a natural saccharide biopolymer synthesized in the human body. It plays a key role in tissue hydration, maintains skin elasticity, and is important for proper joint lubrication. Its primary action is its ability to attract and retain moisture, capable of holding water in an amount more than 1000 times its own weight. With age, the natural production of hyaluronic acid gradually decreases, which affects the skin's appearance and leads to its aging.

The multicomponent hyaluronic acid used in the formula is a combination of three different molecular weights: low (<50kDa), medium (100 to 1000kDa), and high (>1500kDa). The smallest molecules penetrate deeply, reaching the inner layers of the skin, where they exert a regenerating and moisturizing effect. Medium and large molecules remain more superficially, retaining moisture in the upper layers of the skin and creating a feeling of softness and freshness.

● Low molecular weight HA (<50kDA)- This is the most biomimetic size, identical to the natural hyaluronic acid in the body. It penetrates deeply and activates specific CD44 receptors, which stimulate cell proliferation and tissue healing. The result is visibly improved elasticity, denser skin structure, and accelerated recovery.
● Medium molecular weight HA (100 to 1000kDa)- This molecular size acts as a bridge between the surface and depth. It improves smoothness and elasticity without causing irritation. Its main role is to soothe the skin, actively reducing redness and providing a long-lasting sensation of hydration and comfort.
● High molecular weight HA (>1500kDa)- Acts on the surface of the epidermis, creating an invisible "breathable" film. This shield protects the skin from urban pollution, mechanical stress, and dehydration. It provides an immediate visual smoothing effect, filling fine lines and instantly making the skin more radiant.

The importance of active ingredient penetration
Even the most potent active ingredients will not reach their full potential if they cannot penetrate the deeper layers of the skin. The skin is composed of various layers, with the outermost layer, the stratum corneum, serving as a barrier against external influences and threats. This barrier function hinders the penetration of active ingredients, limiting their effectiveness.
For active ingredients to be maximally effective, it is important for the cosmetic cream to prepare both the skin and the ingredients themselves for deeper penetration. The specially developed system of enhancers performs precisely this task. It aids the solubility of ingredients and their penetration through the various layers of the skin.

This allows active substances to reach deeper into the epidermis and dermis, the inner layers, where they can exert the strongest effect and support the skin's restorative and protective processes.

Vitamin C is a fundamental ingredient in skincare, recognized for its ability to neutralize oxidative stress caused by UV rays and atmospheric pollution. Unlike the widely used pure ascorbic acid, which is highly unstable and degrades quickly, this formula incorporates the stabilized form Sodium Ascorbyl Phosphate (SAP).

Technological Advantage

The selection of this specific form ensures that the active ingredient maintains its efficacy and biological activity throughout its period of use. It does not oxidize on contact with air and light, making the product significantly more effective compared to standard alternatives.

Key Skin Benefits:

• Antioxidant Barrier:Protects cellular structures from free radicals and slows down premature aging processes.
• Stimulation of Structural Proteins:Actively supports the natural synthesis of collagen, leading to improved elasticity and density of the dermis.
• Complexion Correction:Helps lighten pigment spots and prevents the appearance of new ones, leaving the skin with an even and radiant appearance.
• Texture Improvement:Regular application smooths fine lines and gives the face freshness and vitality.

Thanks to its stability and optimized absorption, Sodium Ascorbyl Phosphatedelivers maximum results without the risk of irritation characteristic of more aggressive forms of Vitamin C.

Lemon extract is widely used in facial skincare thanks to its rich content of antioxidants, organic acids and bioactive compounds. It helps brighten the complexion, refresh the skin and protect it from external aggressors, while contributing to a more even and radiant look.

Here are the main components of lemon extract that benefit the skin:

• Vitamin C (ascorbic acid): A powerful antioxidant that supports collagen synthesis, evens out skin tone and contributes to more radiant skin, while protecting against free radicals.

• Flavonoids (e.g. hesperidin, eriocitrin): Have strong antioxidant activity, help neutralise oxidative stress and slow down the processes of premature ageing.

• Citric acid (AHA): Helps with gentle exfoliation, removing dead cells and improving skin texture, contributing to a smoother, more even complexion.

• Compounds with anti-tyrosinase activity: Help reduce pigmentation and brighten the skin by inhibiting the enzyme tyrosinase (shown in in vitro studies, including 2025 studies on lemon peel extracts).

• Organic acids and phenolic compounds: Contribute to antioxidant protection, reduce damage from reactive free radicals and help prevent cellular ageing.

• Antimicrobial components: Help limit microbial growth and maintain cleaner, more balanced skin.

• Anti-inflammatory compounds: Help inhibit inflammatory processes and reduce redness and irritation.

This combination of ingredients makes lemon extract effective for antioxidant protection, lightening pigmentation and giving the skin a fresher, more radiant look. Furthermore, unlike lemon essential oil, well-formulated extracts can be used in a way that does not cause photosensitivity, making them suitable for daily care when used correctly.
