What is SPF?
The SPF in sunscreen stands for Sun Protection Factor. SPF is a relative measurement of the time till your sunscreen protects you from harmful UV rays. SPF shows you how much you can minimise the risk of sun-induced damage when you have sunscreen on.
UVA rays are primarily related to the tanning of the skin. On the other hand, UVB rays harm the external layer of the skin aka the epidermis. UVB rays are the reasons you get sunburn. These harmful rays can also cause surface-level skin cancer.
SPF usually protects against UVB rays and lets you know how long it will take for the sun to burn your skin after exposure, compared to when there is no sunscreen on the skin. However, some SPF sunscreens also shield your skin from the negative effects of UVA rays. In other words, sunscreens create a barrier on the skin that protects it from UVA and UVB rays.
What is Broad Spectrum sunscreen, you ask? A broad-spectrum sunscreen can block both the harmful rays and prevent skin damage. UVB rays cause the skin to go red. On the other hand, UVA rays are responsible for photoaging including wrinkles. If you choose SPF sunscreens that only protects against UVB rays, your skin won’t receive UVA protection. Hence, it is imperative to use a Broad Spectrum or Full Spectrum sunscreen that protects against UVA, UVB, blue light, and infrared-A protection.
Now that you know what is SPF, let’s move on to learn about the different types of SPF sunscreens.
Types of SPF
Let’s start with the biggest SPF number first:
- SPF 50 sunscreen offers protection against 98% of UVB rays
- SPF 30 sunscreen will offer protection against 97% UVB rays
- SPF 15 sunscreen blocks 93% of UVB rays
If you use sunscreen SPF 50, it means your skin will probably take 50 times longer to burn as compared to not using sunscreen. Similarly, if you use SPF 15 sunscreen, it will take 15 times longer to burn the skin compared to unprotected skin.
Under specific UV conditions, it takes approximately 10 minutes for the skin to turn red without sunscreen. Therefore, if you use SPF 30 sunscreen, you will get 300 minutes or 5 hours of sun protection. However, it doesn’t mean that a higher SPF would offer longer hours of protection. In means, the blocking effect of SPF sunscreen will diminish after 2 hours. Hence, it is recommended to re-apply sunscreen every two hours.
