SINOSORB BP-3 (UV-9) effectively reduces the damage of UV radiation to the skin by absorbing UV-A and part of UV-B bands in ultraviolet rays. It can absorb ultraviolet energy and convert it into harmless heat energy, thereby preventing ultraviolet rays from damaging cell DNA and causing skin aging, sunburn and other problems. SINOSORB BP-3 (UV-9) has excellent stability and water resistance, and can provide long-lasting protection in daily outdoor activities.
