What’s the deal with SPF?
SPF stands for “sun protection factor” and it’s used to measure just how well the product stands up against UVB rays, a type of radiation that causes sunburn. SPF doesn’t measure UVA rays, which sink down deep into the skin and can cause wrinkles, dark spots and other premature skin aging effects, so it’s a good idea to choose a sunscreen that has broad-spectrum protection which protects against both UVB and UVA rays. Don’t forget, it’s important to reapply any sunscreen at least every 2 hours to make sure you’re getting consistent protection.
