Sunscreen, also known as sunblock, is a protective lotion or cream applied on the skin to safeguard against the harmful effects of ultraviolet (UV) radiation from the sun. Formulated with various active ingredients, it absorbs or reflects the sun's UV rays to prevent skin damage, sunburn, and reduce the risk of skin cancer.
Sunscreen products are differentiated by their Sun Protection Factor (SPF) ratings, which indicate the level of protection offered. Applied generously and regularly, it is a vital addition to outdoor activities and skincare routine to maintain healthy skin and minimize the risk of premature aging.
