Can I use SPF 30 instead of 50?
Can I use SPF 30 instead of 50? SPF 30 blocks about 97% of UVB rays, while SPF 50 blocks about 98% of UVB rays. This means that SPF 50 provides slightly higher protection against UVB radiation compared to SPF 30. However, it's important to note that the difference in protection between SPF 30 and SPF 50 is minimal.
Do you still tan with SPF 50?
With SPF 50, 2% of UV rays are able to penetrate the skin. That's how you're still able to get a tan even with a high SPF. So in order to prevent yourself from sun damage, you need to reapply at least every two hours.
