SPF stands for Sun Protection Factor, and it measures a sunscreen's ability to protect the skin from harmful UVB rays, which can cause sunburn, skin damage, and skin cancer. The SPF number indicates how long the sunscreen will protect the skin from UVB rays compared to not wearing sunscreen. For example, SPF 30 means it will take 30 times longer for the skin to burn compared to wearing no sunscreen. It's important to use sunscreen with a broad-spectrum SPF of 30 or higher to protect against both UVA and UVB rays.
