Sunscreen is a vital skincare product designed to protect the skin from the harmful effects of ultraviolet (UV) radiation emitted by the sun. It acts as a barrier, absorbing or reflecting UV rays, thereby preventing sunburn, premature aging, and reducing the risk of skin cancer. Sunscreen is available in various forms, including lotions, creams, gels, sprays, and sticks, catering to different preferences and skin types. As a collection of products, sunscreens are formulated with active ingredients such as zinc oxide, titanium dioxide, avobenzone, and octocrylene, which work to block or absorb UV radiation. These products are often categorized by their Sun Protection Factor (SPF) rating, which indicates the level of protection they offer against UVB rays, the primary cause of sunburn. Higher SPF values provide greater protection, making them suitable for prolonged sun exposure. Many sunscreens also offer broad-spectrum protection, shielding the skin from both UVA and UVB rays. In addition to traditional sunscreens, the market offers specialized formulations, including water-resistant options for swimming or sweating, tinted versions for a subtle glow, and mineral-based products for sensitive skin. Some sunscreens are enriched with antioxidants, vitamins, and moisturizing agents to nourish and hydrate the skin while providing sun protection. With growing awareness of sun safety, sunscreens have become an essential part of daily skincare routines, encouraging individuals to apply them regularly, even on cloudy days, to maintain healthy and youthful skin.
