Sunscreen is an essential product for protecting the skin from the harmful effects of the sun’s ultraviolet (UV) rays. Sunscreens come in various forms, including lotions, creams, sprays, and gels, and they work by creating a barrier between the skin and UV radiation. They contain active ingredients that either absorb or reflect UV rays, helping to prevent sunburn, skin damage, premature aging, and the risk of skin cancer. The two main types of UV radiation that sunscreens protect against are UVA and UVB rays. UVA rays can penetrate deep into the skin and cause long-term damage, while UVB rays primarily cause sunburn. It’s crucial to choose a broad-spectrum sunscreen that offers protection against both UVA and UVB rays.
