In this raging heat, what is it that bothers us a lot? It is the constant struggle against the ultraviolet rays of the sun. It is difficult to decide and conclude which sunscreen serves our skin type the best. While choosing our sunscreens, we all have come across the term SPF and its numbers. What confuses us is the curious number that follows SPF. SPF number tells us about the time until which our sunscreen will protect us from the never-ending ultraviolet rays of the sun.
ABOUT SPF 30
With SPF 30, the sunscreens allow only 3% of the harmful ultraviolet rays to penetrate your skin. UVB rays are the main reason people develop sunburn and heat rashes, and if exposed to a larger amount, it can also lead to skin cancer. The number after the SPF entails how much protection it offers from UVB rays. The higher the SPF number, the greater the protection from UVB rays.
ABOUT SPF 50
SPF 50 allows 2% of harmful ultraviolet rays to penetrate through the skin pores, and it might seem that there's little to no difference. It might lull you into a false understanding that such a small difference won't ever impact your skin. However, the truth bomb is that if you're working in labs, then using a sunscreen with SPF 50 is more advisable because, in a lab which works with ultraviolet rays, even a slight difference means a lot. However, in daily life, even if you use sunscreen with a higher SPF, it doesn't mean you can expose yourself to as much heat as you want. It won't work that way.
The Sun Protection Factor or SPF 50 sunscreen for the face allows for better protection only if applied with other skincare products. People regularly swimming should not limit SPF to 50 or 30 for the face but should go for more to keep the skin away from chemicals.
Ideally, a sunscreen with SPF 50 is better than the one with SPF 30. However, the preventive measures require being more or less the same in both cases; in both cases, you need to apply more than just sunscreen.
We often mistake applying sunscreen only on a sunny day and not when it is cloudy or during the winter. However, the goal is to protect the skin from ultraviolet rays and not the sun's heat. And even in not-so sunny days, it is mandatory to use sunscreen with a higher SPF to ensure maximum protection.
Choosing the correct sunscreen for your skin might be a battle, but once you get the one cut out for your skin, you can say goodbye to skin issues.
