Sunscreen is a protective skincare product formulated to shield the skin from the harmful effects of ultraviolet (UV) radiation emitted by the sun. It works by using either chemical filters that absorb UV rays or physical/mineral filters like zinc oxide and titanium dioxide that reflect them. Sunscreen helps prevent sunburn, skin damage, premature aging, dark spots, and the risk of skin cancer. Available in various forms such as lotions, gels, sprays, and creams, sunscreens come in different SPF (Sun Protection Factor) levels to suit different skin types, climates, and outdoor activities.

Modern sunscreens often include moisturizing ingredients, antioxidants, and non-greasy or matte finishes, making them suitable for all skin types—including oily, dry, sensitive, and acne-prone skin. Many formulas also offer broad-spectrum protection, guarding against both UVA (aging rays) and UVB (burning rays). When used daily, sunscreen helps maintain healthy, even-toned skin and is considered one of the most important steps in any skincare routine. Its role in long-term skin protection makes it an essential product for overall skin health and well-being.
