LMW-HA has a smaller molecular size and lower viscosity, making it easyPenetrate into the ** layer and tissue cells。It has moisturizing, antioxidant, and wound healing effects, and is often used in skin care products, moisturizers, etcCosmeticsMiddle.
2.Medium molecular weight hyaluronic acid (MMW-HA): molecular weight between 1 million and 10 million.

It is commonly used in products such as skincare products, creams, serums, etc., to provide long-lasting hydration and **softness.
3.High molecular weight hyaluronic acid (HMW-HA): The molecular weight is more than 10 million. HMW-HA has a large molecular size and high viscosity and is capable of formingProtective barrierOn the ** surface, effectively prevented.
Water loss and environmental aggressors. It is commonly used in skin care products, eye creams, etc., to provide moisturizing, moisturizing, and anti-aging effects.
