Physical vs. Chemical Sunscreen
It is 2024, and we hope everyone has implemented SPF in their daily routine by now. But what is the difference between a chemical and physical SPF? We are here to break it down and explain how to detect one from the other on the shelf!
Chemical sunscreens work like sponges, soaking up UV rays and converting them into heat that your skin releases. They’re packed with ingredients like oxybenzone, avobenzone, and octinoxate, which dive into your skin to do their job. These sunscreens are great because they’re lightweight and blend easily into your skin without leaving a weird white cast. They protect against UVA and UVB rays, which is awesome for comprehensive sun protection.
But here’s the thing: some people might find them irritating, especially if you have sensitive skin. Plus, there’s been talk about some of these chemicals not being great for coral reefs and the environment, so that’s something to consider if you’re an eco-conscious sunbather. If you have more sensitive skin, you may notice that these formulas can trigger redness and irritation. If eco-friendliness is a requirement for your sunscreens, your best bet is a mineral sunscreen that’s explicitly labeled as containing no nanoparticles. This typically means choosing a lotion over a mist or spray.
Now, physical sunscreens are like your personal sunblockers! They use minerals like zinc oxide and titanium dioxide to sit on top of your skin and reflect harmful rays away. Think of them as a shield rather than a sponge. They’re gentle on your skin, making them perfect for sensitive types or those with allergies. Plus, they start working immediately.
So, what is the downside of physical sunscreen? It can be a bit thick and leave you looking a bit ghostly if you’re not careful with the application. Some brands are getting better at making them blend in more smoothly, though, with tinted options or finer particles that don’t make you feel like you’re wearing war paint. We always recommend rubbing your finger tips together prior to putting the SPF on your skin to warm it up and help it spread more easily.
Our top pick for a physical SPF is the Skinbetter Tone Smart or any of the Colorescience options.
No matter which one you choose, make sure it’s at least SPF 30 and broad-spectrum to cover all your UV bases. And don’t forget to reapply every couple of hours, especially if you’re splashing around in the water or sweating buckets. Remember, sunscreen is just part of the sun-smart equation. Stick to the shade during the hottest hours, wear sun-safe clothing, and pop on some sunglasses to protect your peepers from UV damage.
Understanding the differences between chemical and physical sunscreens helps you make a smart choice for your skin. Whether you choose a chemical sunscreen with an invisible shield or a physical sunscreen with a gentle barrier, the goal is to keep your skin happy and healthy under the sun’s rays.
