HYDROLYZED HYALURONIC ACID
Hydrolyzed Hyaluronic Acid (HHA), its properties, and benefits:
Chemical Properties
- Chemical Name: Hydrolyzed Hyaluronic Acid
- Molecular Type: Low molecular weight hyaluronic acid fragments
- Molecular Weight: Typically 5,000–50,000 Da (much smaller than native HA)
- Solubility: Highly soluble in water
- Appearance: Viscous or powder form depending on concentration
- pH: Usually stable around 4–7 in aqueous solutions
Mechanism of Action
Hydrolyzed Hyaluronic Acid is depolymerized hyaluronic acid. Its lower molecular weight allows it to penetrate deeper into the skin layers compared to standard HA, enhancing hydration, plumpness, and skin elasticity.
Key Benefits
- Deep Hydration
- Penetrates into the epidermis for long-lasting moisture.
- Helps maintain skin hydration balance at a cellular level.
- Improved Skin Elasticity
- Supports skin suppleness and firmness.
- May help reduce the appearance of fine lines and wrinkles.
- Enhanced Absorption of Active Ingredients
- Its low molecular weight facilitates better delivery of co-administered actives.
- Skin Barrier Support
- Strengthens the natural protective barrier.
- Reduces transepidermal water loss (TEWL).
- Soothing and Anti-Aging
- Promotes smooth and plump skin texture.
- Reduces visible signs of dryness and aging.
Cosmetic Applications
- Serums for deep hydration
- Anti-aging creams and lotions
- Eye creams and lip care products
- Combination formulations with high molecular weight HA, peptides, or antioxidants
Summary
Hydrolyzed Hyaluronic Acid is a low molecular weight HA that provides deep hydration, improved elasticity, skin barrier support, and anti-aging effects. It is highly versatile and synergizes well with other skin care actives.
