Repair and prevent
Photoburn or sunburn caused by sun exposure, such as skin reddening, blackening, peeling, etc., is mainly due to the effect of ultraviolet rays in sunlight. Sodium hyaluronate can promote the regeneration of the injured part of the skin by promoting the proliferation and differentiation of epidermal cells and scavenging oxygen free radicals, and prior use also has a certain preventive effect. Its mechanism of action is different from that of UV absorbers commonly used in sunscreens. Therefore, when ha and UV absorbers are used in sunscreen skin care products, they have a synergistic effect and can reduce the penetration of UV rays and the damage caused by a small amount of UV rays. Repair skin damage and play a dual protective role.
The combination of sodium hyaluronate, egf and heparin can accelerate the regeneration of epidermal cells, making the skin delicate, smooth and elastic. When the skin suffers from mild burns and scalds, applying a water-based cosmetic containing sodium hyaluronate on the surface can relieve pain and accelerate the healing of the injured skin.
 
Lubrication and Film Formation
Sodium hyaluronate is a high molecular polymer with strong lubricity and film-forming properties. Skin care products containing sodium hyaluronate have obvious lubricating feeling when applied, and feel good. After being applied to the skin, it can form a film on the surface of the skin, making the skin feel smooth and moisturizing, and protecting the skin. Hair care products containing sodium hyaluronate can form a film on the surface of the hair, which can moisturize, lubricate, protect the hair, eliminate static electricity, etc., making the hair easy to comb, elegant and natural.
