Detailed answer

Sunscreen is a skincare product that provides protection against the sun's ultraviolet (UV) radiation. It is typically available in the form of creams, lotions, gels, or sprays. Sunscreen works by either absorbing or reflecting the UV rays, preventing them from penetrating the skin. It contains active ingredients like zinc oxide or titanium dioxide, which act as physical UV filters, and/or various chemicals that act as chemical UV filters. Applying sunscreen to exposed skin areas helps reduce the risk of sunburn, premature skin aging, and skin cancer caused by UV radiation. It is important to choose a broad-spectrum sunscreen with a high sun protection factor (SPF) and reapply it regularly for optimal protection.
