Overview
When it comes to sun protection, not all sunscreens are made equal. Understanding the SPF meaning is the first step in choosing the right formula for you. According to the FDA, the SPF, also known as Sun Protection Factor, is a measure of how much solar energy (UV radiation) is required to produce sunburn on protected skin.1 From the differences between SPF 30 and 50 and how each helps protect your skin, to finding a sunscreen tailored to your skin tone and specific needs, it’s all about matching protection to lifestyle.
Important Facts About SPF Numbers
- Sunscreens come in a variety of SPF levels, but the ones you’ll spot most often are SPF 30 and SPF 50.
- A higher SPF typically means stronger protection, but it doesn’t mean all-day coverage, so you’ll still need to reapply frequently and generously to help protect your skin.
- Dermatologists recommend wearing sunscreen SPF 50.
