In respect to this, which SPF is best for skin?

SPF 30 is the most common level for most people and skin types. No sunscreen can block all UV rays, but what we do know is: SPF 15 blocks 93% of UVB rays, SPF 30 blocks 97% of UVB rays and SPF 50 blocks 98% of UVB rays. So, the difference between 30 and 50 is about 1 percent.

Beside above, is SPF 50 good for skin? Both of them increase your risk of skin cancer. But the truth is that higher-SPF products are only marginally better at shielding you from UVB, according to both the EWG and the Skin Cancer Foundation. SPF 30 blocks nearly 97% of UVB radiation, SPF 50 blocks about 98%, and SPF 100 blocks about 99%.

Subsequently, one may also ask, is higher SPF better?

While an SPF of 15 blocks 93% of UVB rays, an SPF of 30 blocks 97% and an SPF of 50 blocks 98%, going higher than 50 doesn't increase your protection by any significant amount. So as long as you are using an SPF of at least 30 daily, you're good to go.
