Is 100 SPF bad for your skin?

Yes, 100 SPF is too high for everyday use and can be bad for your skin. Sun protection factors (SPF) measure the amount of protection a sunscreen product provides against ultraviolet B (UVB) radiation. SPF 100 blocks up to 99.9 percent of UVB rays, while SPF 30 blocks up to 97 percent of UVB rays. Because of the high level of protection, SPF 100 can interfere with the skin’s natural process of absorbing vitamin D and other beneficial elements from the sun. It can also cause irritation and skin sensitivity. For everyday use, experts recommend using a sunscreen with an SPF of 30 or less.

Is SPF 50 or 100 better?

SPF 50 provides protection from 97.5% of UVB rays, while SPF 100 provides protection from 99% of UVB rays. Generally speaking, SPF 100 is a better choice, since it offers more protection from harmful UVB rays. However, it is important to note that both SPF 50 and SPF 100 should be used in conjunction with other sun protection measures, such as wearing protective clothing and seeking shade.

Is SPF 70 or 100 better?

SPF 100 is more effective than SPF 70 in protecting against UVB radiation and is recommended for extended periods of direct sun exposure or for people with a higher risk of skin cancer. SPF 70 blocks out 97% of UVB radiation, while SPF 100 blocks out 99%. Additionally, SPF 100 is more resistant to water and sweat, so it lasts longer and provides more consistent protection.
