When it comes to spending time outside with friends, family, or even your four-legged companions, one thing is essential: Sun protection. But which SPF should you go for – 30 or . 50? What's the difference? And are there any other ways to stay safe in the sun without having to lather up?
Let’s break down these two ratings and look at today’s best ways to stay safe from UV rays outdoors.
What’s the Difference Between SPF 30 and 50?
SPF (short for Sun Protection Factor) is a metric used to gauge the effectiveness of sunblock in preventing sunburns caused by UVB rays. SPF 30 filters 97% of UVB rays, meaning it takes 30 times longer for skin to burn than if you used no sunscreen. To put it another way, SPF 30 provides the same level of sun exposure in 30 minutes as one would receive in one minute without protection.
SPF 50 blocks 98% of UVB rays, which may feel like a small difference, but reduces the UV radiation that reaches the skin compared to SPF 30 by up to 50%.
It's also worth noting that SPF values over 50 do not necessarily equate to enhanced skin protection since no sunscreen can block 100% of UV rays.
Other factors can impact sunscreen’s effectiveness, like whether the product is broad-spectrum (protects against UVA and UVB rays), water or sweat resistant, properly (or improperly) applied, and how it’s stored.
How often you should reapply varies based on the product, but most sunscreens only protect for approximately 2 hours. This timeframe can decrease when exposed to elements such as water, sweat, or high temperatures that can cause the sunscreen to break down faster.
Did you know there’s a more effective, less demanding way to protect your skin from the sun? It’s called UPF-rated clothing, and it will make every sunny day adventure that much safer! It’s also what the Skin Cancer Foundation recommends as the first and most effective defense against UV exposure.
What is UPF-Rated Apparel?
UPF (short for Ultraviolet Protection Factor) is a metric that indicates how much UV radiation (UVA and UVB) the fabric allows to reach the skin. A material's highest level of UV protection is UPF 50+, which blocks 98% of UVA and UVB rays.
Unlike sunscreen, UPF-rated clothing provides consistent protection from UVA and UVB rays without wearing off, making it easy to enjoy your day without pausing to reapply your sunscreen. Today’s best UPF-rated apparel is comfortable, breathable, and provides effortless sun protection.
