Sunscreen SPF Guide: Protecting Your Skin from Sunburn

There is no one definitive answer to this, as it depends on various factors such as skin type, time of day, and geographic location. However, a good rule of thumb is to use a sunscreen with an SPF of at least 30. This will provide broad-spectrum protection against UVA and UVB rays and significantly reduce the risk of sunburn, skin damage, and skin cancer.
