Sunscreen is essential in summer (and all year round) because it helps protect your skin from the harmful effects of the sun’s ultraviolet (UV) rays. The UV rays can cause sunburn, premature aging, and skin cancer.

When you apply sunscreen, it creates a barrier on your skin that helps absorb and reflect UV radiation. This barrier helps to prevent the UV radiation from penetrating your skin and damaging your cells.

Using sunscreen is especially important during the summer months when the sun is stronger and the days are longer, meaning you are more likely to spend more time outdoors. Even if it’s a cloudy day, UV rays can still penetrate through the clouds and harm your skin.

Therefore, wearing sunscreen with a high SPF (Sun Protection Factor) can help protect your skin from harmful UV rays and keep it healthy and youthful-looking. It is recommended to use a broad-spectrum sunscreen with an SPF of at least 30, and reapply it every two hours or after swimming or sweating.
