sunscreen lotion is a topical product designed to protect the skin from the harmful effects of ultraviolet (UV) radiation from the sun. It contains active ingredients that either absorb, reflect, or scatter these rays, helping to prevent sunburn and reduce the risk of skin cancer. Sunscreen is available in various forms, including lotions, creams, sprays, and sticks. To be effective, sunscreen should be applied generously to all exposed skin at least 15 minutes before sun exposure. It is important to choose a product with a suitable sun protection factor (SPF) rating, which indicates the level of protection against UVB rays. Regular reapplication is necessary, especially after swimming or sweating.
