To some degree, having a higher SPF is better for protection. However, after a certain point, it may not matter. Dermatologists recommend using sunscreen between 30-50 SPF for everyday use.
Some argue that any sunscreen over SPF 50 is not worth it as it only provides marginally better sun protection and can cause other health risks such as hormone disruption and tissue damage. SPF 50 protects against 98% of UVA rays, while SPF 100 protects against 99% of UVA rays.
