Sun Protection Factor (SPF) is a numerical rating system used to measure the level of protection a sunscreen or sunblock product offers against the harmful effects of ultraviolet (UV) radiation from the sun. SPF indicates how effectively the product can shield your skin from the sun’s UVB (ultraviolet B) rays, which are responsible for causing sunburn, skin damage, and increasing the risk of skin cancer.

Understanding SPF
How SPF Works
SPF, which stands for Sun Protection Factor, is a numerical rating system that measures a sunscreen’s ability to protect your skin from the harmful effects of ultraviolet (UV) radiation from the sun. It works by creating a protective barrier on your skin that absorbs, reflects, or scatters the UVB rays, preventing them from penetrating your skin and causing damage.
Different Types of UV Radiation
Understanding the different types of UV radiation, including UVA and UVB, is crucial for effective sun protection. UVB rays are primarily responsible for causing sunburn, while UVA rays contribute to premature aging. A good sunscreen should offer protection against both types of UV radiation.
SPF Ratings Explained
The SPF rating on sunscreen products indicates the level of protection they provide against UVB rays. For example, SPF 30 sunscreen allows you to stay in the sun about 30 times longer than without protection before experiencing sunburn. Higher SPF ratings provide more protection but require proper application for maximum effectiveness.
