SPF Ratings and what they mean
Hello everyone👋🏾
Today's topic is SPF Ratings.
SPF also known as 'Sun Protection Factor' the SPF number indicates how much longer than usual you can stay in the sun without getting sunburned.
For example, if you can stay in the sun unprotected for twenty minutes before your skin begins to burn, SPF 30 allows you to remain in the sun for thirty times longer, or ten hours, without burning.
This should not give anyone an excuse to not reapply their sunscreen because sunscreen degrades on sunlight so they become lee effective over time that's why its important to reapply sunscreen every 2 hours.
When buying a sunscreen make to sure to look for a broad spectrum sunscreen that has a label stating that it protects against UVA and UVB rays because SPF only means it protects against UVB rays.
Hope this post clears some confusion.
Let me know your thoughts on this in the comments.
