Sunscreen is an essential part of protecting your skin from the sun’s harmful ultraviolet (UV) rays. UV rays can damage the skin even on cloudy days and during short periods outdoors. Over time, this damage increases the risk of skin cancer, including melanoma, which can be serious. Using sunscreen regularly helps lower this risk.

Sunscreen also protects against sunburn. Sunburn is not just painful; it is a sign that your skin cells have been injured. Repeated sunburns, especially in childhood and teenage years, greatly increase the chance of long-term skin problems later in life.

Another important benefit of sunscreen is preventing early skin aging. UV rays break down collagen and elastin, which keep skin firm and smooth. Without protection, this can lead to wrinkles, dark spots, and uneven skin tone at a younger age.

For best protection, use a broad-spectrum sunscreen that protects against both UVA and UVB rays, with an SPF of 50. Apply it generously to all exposed skin 15–20 minutes before going outside, and reapply every two hours or after swimming or sweating. Sunscreen should be used daily, along with hats, protective clothing, and shade, to keep your skin healthy throughout your life.
