Is higher SPF better?

Higher SPF does offer more protection against UV rays, but it’s not a straightforward improvement. While SPF 30 blocks about 97% of UVB rays and SPF 50 blocks about 98%, the difference in protection is minimal. It's also important to remember that no sunscreen can provide complete protection, regardless of the SPF.

Key points:

• SPF measures protection against UVB rays only.
• Higher SPF can lead to a false sense of security.
• Sunscreen needs to be reapplied regularly for effective protection.
• Other factors like skin type and sun exposure duration matter too.
