Hyaluronic Acid Serum

1. Ingredient Science

Hydrolyzed Hyaluronic Acid (Low Molecular Weight)

Hydrolyzed hyaluronic acid is fragmented into smaller molecules that penetrate deeper into the epidermis. It binds to water molecules inside the skin, increasing internal hydration and restoring volume. In addition, it stimulates the expression of aquaporin-3 water channels, improving intracellular transport of water and glycerol. Clinical studies show that low molecular weight hyaluronic acid reduces wrinkle depth and improves elasticity after four weeks of use.

Benefits: Deep hydration, plumping, visible wrinkle reduction, improved elasticity.

Ideal for: Dehydrated, aging, or dull skin.

Sodium Hyaluronate (High Molecular Weight)

Sodium hyaluronate forms a hydrating film on the surface of the stratum corneum. This water-rich layer prevents transepidermal water loss and instantly smooths micro-relief irregularities. It creates a soft, cushion-like effect, leaving skin silky and comfortable. Clinical evidence demonstrates that high molecular weight hyaluronic acid improves skin smoothness and reduces dryness within days of application.

Benefits: Surface hydration, immediate comfort, smoothing of fine lines.

Ideal for: Dry, rough, or sensitive skin.

Panthenol (Provitamin B5)

Panthenol is a biologically active form of vitamin B5 that penetrates the epidermis and is converted to pantothenic acid inside cells. It acts as a humectant, binding water, and supporting barrier recovery. Panthenol also has anti-inflammatory properties, reducing irritation, redness, and sensitivity. Clinical data shows that panthenol accelerates wound healing and barrier repair.

Benefits: Soothing, hydration, barrier support, redness reduction.

Ideal for: Sensitive, irritated, or reactive skin.

Pentylene Glycol

Pentylene glycol functions both as a humectant and as a skin penetration enhancer. It binds water in the epidermis, contributing to hydration, and helps other active ingredients penetrate more effectively. It also has mild antimicrobial activity, which supports product safety and skin balance.

Benefits: Hydration, improved delivery of actives, protection against microbes.

Ideal for: All skin types, especially combination or sensitive.

Citric Acid

Citric acid acts as a gentle pH adjuster and mild exfoliant. It helps maintain the serum at a skin-friendly acidic pH, supporting barrier function. It also provides light exfoliation, smoothing the skin surface and improving radiance.

Benefits: Radiance, smoother texture, balanced skin environment.

Ideal for: Dull, uneven, or tired skin.

Ammonium Acryloyldimethyltaurate/VP Copolymer

This advanced polymer acts as a stabilizer and texturizer. It creates a lightweight gel network that ensures even distribution of active ingredients across the skin and improves the sensorial feel of the serum.

Benefits: Lightweight texture, even delivery of actives, elegant feel.

Ideal for: All skin types.

Hydroxyacetophenone

Hydroxyacetophenone is an antioxidant and skin-soothing agent. It neutralizes free radicals, reducing oxidative stress, and helps protect against irritation. It also stabilizes the formula, keeping the serum safe and effective.

Benefits: Antioxidant protection, soothing effect, formula stability.

Ideal for: Sensitive, stressed, or urban-exposed skin.

Aqua (Water)

Water is the universal solvent that carries all active ingredients. In this serum, it serves as the base for hydration and lightweight absorption.

Benefits: Hydration, delivery of actives.

Ideal for: All skin types.

Parfum (Fragrance)

A delicate fragrance adds sensorial pleasure, transforming routine application into a luxury skincare ritual.

Benefits: Sensory enjoyment.

Ideal for: Customers who value elegance in skincare.

2. Formula Synergy

This serum combines multi-weight hyaluronic acid for surface and deep hydration, panthenol for soothing and barrier repair, and pentylene glycol to enhance delivery and antimicrobial safety. Citric acid brightens, while hydroxyacetophenone protects from oxidative stress. The result is a serum that not only hydrates deeply but also strengthens, soothes, and protects the skin, preparing it for cream application.

Result: Immediate comfort, long-lasting hydration, and enhanced resilience.
