Introduction On What is SPF
What is SPF and why is it such a “hot” topic in beauty circles? SPF stands for “Sun Protection Factor,” and it is a measure of how much protection a sunscreen product gives to our skin. Long-time exposure to the sun can lead to tanning, premature ageing, sunburns, and even skin cancer in extreme cases. That is why using a good SPF sunscreen before venturing out in the sun is so important. Talking of SPF, people often wonder what SPF numbers indicate. Here is all you need to know about SPF.
What is SPF and why is it important?
SPF or Sun Protection Factor is a relative measurement of a sunscreen product’s ability to protect your skin from the damaging effects of UVB radiation. It is an important factor to consider when buying sunscreen.
UVB rays emitted by the sun can cause sunburns and has a big role to play in the development of skin cancer. These rays primarily affect the epidermis, the outer layer of the skin. The sun also emits UVA rays which can also harm the skin. However, SPF numbers typically measure a sunscreen’s ability to offer UVB protection only.
Now, one might ask what is SPF 15 or SPF 30? How are they different, and which one is better?
What do SPF numbers mean?
The SPF numbers on bottles of sunscreen lotions can be very confusing. What do these numbers mean and which SPF number is the best for you? An SPF number is an indication of how much protection a sunscreen product can provide your skin.
A product with SPF 15 blocks 93% of the sun’s UVB rays while SPF 30 sunscreen blocks 97%. SPF 50 blocks 98% of UVB rays and SPF 100 blocks 99% (1). No sunscreen can offer you 100% protection from UVB rays.
Is a higher SPF always better?
People mistakenly believe a sunscreen with a higher SPF is always better. However, it is not so. Under ideal conditions, a sunscreen product with a higher SPF offers more protection against UVB rays than other products with lower SPF values. But practically speaking, the protection offered increases only marginally with higher SPF values.
Dermatologists generally recommend using a sunscreen product with at least SPF 30 for optimum benefits. SunScoop products offer SPF 40 and higher. The amount of sunscreen you apply also determines how much you are protected. There is very little difference between the best protection offered by medium and high SPF products (2).
How to choose the best SPF for my skin?
Dermatologists recommend going for a sunscreen with SPF 30 or more. It is better to go for products that offer broad spectrum protection (like SunScoop) and are water-resistant. Apply sunscreen 15 minutes before going out and reapply approximately every two hours.
In closing thoughts, what is SPF?
Wearing a sunscreen with an adequate SPF all the time is a necessary step in skincare. Exposing unprotected skin to the harmful UV rays of the sun can not only lead to tanning and sunburn but can also increase your risk of skin cancer.
Choose a product with at least SPF of 30 for outdoor use. Those who spend a lot of time in the sun can benefit from using SPF 40 or SPF 50 like the SunScoop sunscreens. Visit India’s first SPF-focused brand, SunScoop, to explore a wide range of sunscreen products for your skin.
