While both SPF 30 and SPF 50 offer excellent protection against harmful UV rays, SPF 50 provides only marginally better protection than SPF 30. SPF 30 filters out 96.7% of UV radiation, while SPF 50 blocks 98%. This means that only a slightly higher percentage of UV rays reach your skin with SPF 50.
Many experts recommend using an SPF 30 sunscreen because it provides a high level of protection and is often more readily available and affordable. However, if you're particularly concerned about UV exposure or have sensitive skin, SPF 50 might be a better choice.
Ultimately, the best SPF for you depends on your individual needs and preferences. The most important factor is ensuring you apply sunscreen liberally and reapply it every two hours, especially after swimming or sweating.
