"Expert Tips for Perfect Sunscreen Use and Sun Protection"

Sunscreen is essential for protecting your skin from harmful UV rays, which can cause skin cancer and premature aging. Dermatologists recommend using a broad-spectrum sunscreen with at least SPF 30, applying it daily, even indoors, and reapplying every two hours when outdoors. Both mineral and chemical sunscreens offer good protection, but mineral sunscreens are less likely to cause irritation. Sunscreen should be applied generously and replaced every three years or if it shows signs of degradation. Additionally, sun-protective clothing and seeking shade during peak sun hours are important for comprehensive sun protection.
