What Are Sun Screen Lotions
Sun screen lotions are topical products designed to absorb or reflect ultraviolet radiation from the sun. They help reduce sunburn, long-term skin damage, and the risk of certain skin conditions. Most formulations combine active filters with emollients and preservatives to create a spreadable protective layer on the skin.
How SPF and Protection Types Work
SPF measures protection against UVB rays that cause sunburn. Higher SPF values block a greater percentage of UVB, but no product blocks all rays. Broad-spectrum lotions also provide UVA protection, which contributes to aging and long-term skin damage. The choice between chemical and mineral filters depends on skin sensitivity and desired texture.
How to Choose and Apply Sun Screen Lotions
Select a lotion with an SPF appropriate for your exposure time and skin type. Apply a generous, even layer at least 15 minutes before sun exposure, and reapply after swimming, sweating, or towel drying.
