The right level of SPF to use depends on your skin type, how much time you spend outdoors, and the intensity of the sun’s rays. Generally, it is recommended to use sunscreen with at least SPF 30.

SPF stands for Sun Protection Factor, and it measures the level of protection a sunscreen provides against UVB rays, which cause sunburn and can also lead to skin cancer.

SPF 30 blocks about 97% of UVB rays, while SPF 50 blocks about 98%. So, there is only a slight difference in protection between SPF 30 and SPF 50. However, it is essential to apply sunscreen generously and frequently, regardless of the SPF level, to ensure adequate protection.

If you have fair skin or spend a lot of time outdoors, consider using a higher SPF sunscreen or using other protective measures such as seeking shade or wearing protective clothing.
