Cosmetic-grade Hyaluronic Acid: The Key Ingredient to Unlock Effective Moisturizing
Hyaluronic acid (HA) is a polysaccharide substance that exists naturally in the human body and is widely distributed in the skin, synovial fluid, eyeballs, etc. Its biggest feature is its superb water-retaining ability - 1 gram of HA can absorb up to 500-1000 times the amount of water, and is known as the "natural moisturizing factor."
The application of cosmetic grade hyaluronic acid (HA) in facial cream is an important manifestation of its versatility and moisturizing properties. As a "water-locking barrier" in the skin care process, facial cream needs to take into account both immediate hydration and long-term moisture lock. Hyaluronic acid, with its unique molecular structure and properties, has become one of the core ingredients of facial cream formulas.

Functions
1.Multi-level moisturizing network
Facial creams often use high-molecular HA to form a breathable water film on the skin surface to reduce transepidermal water loss; combined with low-molecular HA, it penetrates deep into the stratum corneum to activate natural moisturizing factors and achieve three-dimensional hydration "from the inside out".
2.Repair barrier function
Low-molecular HA strengthens the stratum corneum structure by promoting the expression of filaggrin and claudin, and is especially suitable for dry and sensitive skin cream formulas.
3.Improve skin feel and ductility
The high viscoelasticity of hyaluronic acid can optimize the texture of the cream and reduce greasiness. Cross-linked hyaluronic acid or hydrolyzed HA fragments are often used to create a "matte" skin feel, which is suitable for oily skin.
4.Synergistic anti-aging effect
In anti-aging creams, HA is compounded with peptides, retinol and other ingredients to stimulate fibroblast activity, promote collagen production, and relieve the drying irritation of retinol ingredients.
