☀️ Next-Level Sun Protection Starts with What You Can’t See
The sun isn’t just brightening our day—it’s also sending down UV rays (UVA, UVB, and UVC) across a range of 100–400 nm.
Don’t worry, UVC gets blocked by the ozone layer, so it’s not crashing your skincare routine.
UVB is the dramatic one—it hits the surface of your skin and causes those very obvious sunburns (yes, the “I forgot sunscreen” kind).
UVA, on the other hand, is the sneaky one. Less intense but around all day, every day, rain or shine, and it goes deeper into your skin—quietly contributing to wrinkles, dark spots, and loss of firmness over time.
Here’s the twist: while UVB damage shows up fast, UVA damage plays the long game, building up slowly and showing its effects years later.
And it gets more interesting—UVA includes ultra-long rays (UVA1, 340–400 nm), which make up about 30% of the UV reaching Earth. That’s why modern sunscreens are stepping up their game to protect against them.
🧪 Meet the Filters: Mexoryl & Tinosorb
Not all sunscreens are created equal—and this is where things get interesting.
Mexoryl filters (like Mexoryl SX, XL, and the newer Mexoryl 400) are known for their strong, stable UVA protection, especially in the long UVA range. They help fill the gaps that older filters often miss.
Tinosorb filters (such as Tinosorb S and M) are multitaskers—they provide broad-spectrum protection (UVA + UVB) and are extremely photostable, meaning they don’t break down easily in the sun.
Together, these filters are often used in advanced European sunscreens to deliver more complete, long-lasting protection, especially against those hard-to-block ultra-long UVA rays.
🔬 The Innovation Gap between us and Europe
The biggest difference? Speed of innovation.
-
The US hasn’t approved a new UV filter since 1999
-
Meanwhile, Europe continues to develop filters targeting ultra-long UVA (the deepest penetrating rays) such as Tinosorb S/M, Mexoryl XL, Uvinul A Plus)
⚖️ Why It Matters for Your Skin
-
US sunscreen = still effective, especially if used properly. But either based on potential hormone disrupter and reef damaging avobenzone, octocrylene, or pasty looking zinc oxide and titanium dioxide
-
EU sunscreen = often more advanced, especially for anti-aging (UVA) protection
-
The best sunscreen? The one you’ll actually wear every day
