Sunscreen is an essential skincare product designed to protect the skin from the harmful effects of ultraviolet (UV) radiation. Exposure to UV rays can lead to premature aging, sunburn, and increase the risk of skin cancer. Sunscreen works by either absorbing or reflecting UV rays, creating a barrier that helps prevent skin damage caused by sun exposure.
Most sunscreens contain active ingredients such as zinc oxide, titanium dioxide, or chemical filters like avobenzone and octinoxate, which offer broad-spectrum protection against both UVA and UVB rays. UVA rays contribute to skin aging, while UVB rays are responsible for sunburn. Broad-spectrum sunscreens protect against both, ensuring comprehensive defense.
Sunscreen is available in various formulations, including lotions, sprays, gels, and sticks, and is suitable for all skin types, including sensitive skin. Many sunscreens are also enriched with moisturizing ingredients, antioxidants, or vitamins like vitamin E to help nourish the skin while protecting it.
To ensure maximum effectiveness, it is important to apply sunscreen generously to all exposed areas of the skin at least 15 minutes before sun exposure. Reapply every two hours or after swimming or sweating. Regular use of sunscreen can help maintain healthy, youthful skin and reduce the long-term risk of sun damage.
