Sunscreen is an essential component of any skincare routine because it helps protect your skin from the harmful effects of the sun's UV (ultraviolet) rays. UV radiation can cause sunburn, premature aging, and an increased risk of skin cancer.
When you apply sunscreen, it creates a protective barrier on your skin that absorbs or reflects the UV radiation, helping to prevent damage. Sunscreen can also help to prevent hyperpigmentation and dark spots from forming on the skin.
It's important to wear sunscreen every day, even on cloudy or overcast days, because UV rays can penetrate through clouds and cause damage to your skin. When choosing a sunscreen, look for a broad-spectrum sunscreen that protects against both UVA and UVB rays, with an SPF (Sun Protection Factor) of 30 or higher. Be sure to reapply sunscreen every two hours, or more frequently if you're sweating or swimming.
