Sunscreen is a vital part of any skincare routine, especially in regions with strong sun exposure, like India. However, have you ever wondered what is SPF in Sunscreen and the meaning of those cryptic numbers on sunscreen bottles, such as SPF 15, SPF 30, or SPF 50?
In this article, we will understand what is SPF in Sunscreen, and explore its significance and benefits of sunscreen. Learn how to choose the right level of protection for your skin to keep your skin safe and healthy.
Understanding What is SPF in Sunscreen
SPF stands for Sun Protection Factor. It measures how effectively a sunscreen product can shield your skin from the harmful ultraviolet (UV) rays of the sun. These UV rays are categorized into two types – UVA and UVB – each contributing to various forms of skin damage.
UVA rays are responsible for premature aging, causing wrinkles and fine lines, while UVB rays are notorious for causing sunburn and potentially contributing to skin cancer. SPF is a measure that indicates a sunscreen’s ability to protect your skin from UVB rays.
If you’re using an SPF 30 sunscreen, it means it will take 30 times longer for your skin to get sunburned compared to not wearing any sunscreen. SPF 50 provides even higher protection.
Understanding SPF Levels & Decode the Numbers:
- SPF 15: This level of protection blocks about 93% of UVB rays. It is suitable for daily activities with limited sun exposure, like running errands or working indoors.
- SPF 30: With approximately 97% protection against UVB rays, SPF 30 is ideal for moderate sun exposure. It is recommended for daily outdoor activities.
- SPF 50: Offering around 98% protection, SPF 50 is excellent for prolonged sun exposure, like spending a day at the beach or engaging in outdoor sports.
It’s crucial to note that the increase in SPF numbers does not mean a proportional increase in protection. For instance, SPF 50 does not provide twice the protection of SPF 25. The difference in protection between SPF 30 and SPF 50 is only about 1-2%. The protective effect of sunscreen usually wears off after 2 hours, which means you’ll need to reapply it every 2 to 3 hours for continued protection.
