Hyaluronic acid OLIGO
Description
Oligo Hyaluronic Acid – Very Low Molecular Weight
Oligo Hyaluronic Acid (sodium hyaluronate oligomers) is characterized by the lowest molecular weight currently available on the cosmetic market. This pure active overcomes the surface barrier of the skin, penetrating through the stratum corneum down to the lower epidermal layers. Unlike conventional variants that retain water only on the outside, Oligo Hyaluronic Acid acts as a deep restructurer: it activates the synthesis of cellular cohesion proteins, stimulates endogenous production of hyaluronic acid, and recharges intercellular water reserves. The result is an improvement in elasticity, a visible reduction in signs of photo-aging, and a structural restoration of skin firmness.
Ingredients (INCI): Hydrolyzed Sodium Hyaluronate.
Technical Characteristics
- Molecular Weight: Ultra-low, situated below 10 kDa (Kilodaltons).
- Appearance: Fine powder, white, odorless.
- Solubility: Completely water-soluble.
- Cosmetic function: Deep humectant, elasticity booster, cellular cohesion protector, structural anti-aging agent.
- Indicative dosage: 0.1% - 0.5%
Information from Specialized Literature
The biological performance and penetration dynamics of hyaluronic acid oligomers are demonstrated through rigorous histological research and clinical studies:
- Deep Absorption and Localization: Advanced spectroscopic studies have shown that hyaluronic fragments with a molecular weight below 10 kDa do not remain trapped on the surface of the epidermis. They effectively cross the stratum corneum and distribute into the deep layers of the epidermis, providing direct and lasting cellular hydration.
- Stimulation of Cohesion Proteins: Specialized literature documents that the presence of very low molecular weight hyaluronic acid stimulates the expression of genes responsible for the synthesis of junction proteins. This action strengthens the skin's protective barrier, reducing transepidermal water loss (TEWL) and increasing resistance to external aggressors.
- Multiplication of Skin Elasticity: Clinical evaluations on human subjects show that topical application of hyaluronate leads to a significant increase in elastic recoil, improving skin micro-relief and diminishing the appearance of established wrinkles by restructuring the extracellular matrix.
Main Properties
- Deeply Infuses Moisture: Retains water in deep intercellular niches, providing a long-term hydrating effect.
- Activates the Matrix: Promotes proliferation, reconstruction, and repair of skin tissue, activating the recovery of the extracellular matrix function.
- Elasticity and Firmness Booster: Restores tone and density to devitalized, thinned skin or skin affected by the passage of time.
- Skin Barrier Repair: Accelerates epidermal recovery after exposure to climatic stress factors (cold, wind, solar radiation).
Applications
- Cosmetic ingredient recommended for creating a wide range of cosmetic products.
- High-performance anti-aging aqueous serums and cellular booster lotions.
- Day and night creams designed for restructuring mature, withered, or deeply dehydrated skin.
- Post-peeling cosmetic treatments to accelerate comfort and skin recovery.
- Specific formulations for areas with thin skin (eye contour, neck, décolleté).
- Premium toning lotions and dermatocosmetic structural refreshing sprays.
Formulation Guide and Premium Synergies
Oligo Hyaluronic Acid, unlike the macromolecular variant, is much easier to integrate into formulas as it does not tend to form dense gelled clumps. Since it does not thicken the formula, it is suitable for aqueous serums at maximum concentration without altering product rheology.
- General procedure: Dissolve in distilled water or hydrosol from the recipe at room temperature. Incorporation at temperatures below 40°C is recommended.
- In emulsions: Premixing in a glycol (glycerin, propanediol) is recommended to facilitate incorporation and homogenization.
- pH Range: Stable and active in a pH range between 4.0 and 7.5.
Safety in Use and Storage
Safety Profile: High biotechnological purity product, characterized by exceptional dermatological tolerance. It is non-irritating, non-sensitizing, making it suitable for any skin type.
Warnings: For external cosmetic use only. The powder is extremely fine; handle with care during weighing to avoid inhalation. Keep out of reach of children.
Storage: Keep in a tightly closed container, in a dry, cool place, protected from the action of ambient moisture.
