Is U.S. Sunscreen Less Effective Than International Brands?
As skincare-conscious consumers become more ingredient-savvy, one question keeps surfacing: Is sunscreen in the U.S. actually less effective than what’s available internationally—especially in Australia, Europe or Japan? The short answer: it can be. And the reason why may surprise you.
What Makes Sunscreen "Effective?"
An effective sunscreen does two things:
- Blocks both UVA and UVB rays , which cause sunburn, premature aging, and skin cancer.
- Stays stable under heat, water, sweat, and UV exposure.
The gold standard is broad-spectrum, photo-stable, water-resistant protection—ideally with minimal white cast and skin irritation.
Why U.S. Sunscreen Ingredients Are Limited
U.S. sunscreens are regulated by the FDA, which treats them as over-the-counter drugs —requiring extensive approval for each active ingredient.
As a result:
The U.S. has fewer approved UV filters —most notably, it lacks access to newer-generation filters like Tinosorb S , Tinosorb M, Mexoryl SX and Uvinul A Plus, which are widely used in Europe and Asia
The last UV filter approved in the U.S. was in the 1990s
By contrast, Australia and the EU regulate sunscreens as cosmetics, allowing newer, more sophisticated filters on the market much faster.
A Closer Look: U.S. vs. Australian & European Sunscreens
| Feature | US Sunscreens | International Sunscreens |
| #UV filters allowed |
~16 |
25-30+ |
| Broad-spectrum efficacy | Varies by brand, UVA coverage often limited | Superior UVA & UVB protection in most products |
| Filter innovation | Slow (regulated by FDA) | Fast (cosmetic-regulated) |
| Texture & wearability | Often thicker, greasier, more white cast | Lightweight, elegant textures, minimarl cast |
So, Is U.S. Sunscreen Enough?
Yes—if used correctly and consistently. But:
Many U.S. sunscreens lack robust UVA coverage.
They may feel less wearable, which affects how often people reapply.
For those with melasma, hyperpigmentation or sun sensitivity, international formulas can offer more comprehensive protection with better wearability.
Why JOJU Believes in Skin Protection Beyond SPF
We created JOJU because relying on sunscreen alone—especially limited U.S. formulations— isn’t enough.
Our UPF 500 sun shirts are lab-tested to block 99.82% of UVA/UVB rays , and unlike sunscreen, they don’t wash off, rub off or degrade over time. They complement your skincare—not compete with it.

FAQ
Can I wear U.S. sunscreen and still be protected?
Yes. Just make sure it’s labeled "broad-spectrum," apply generously and reapply every 2 hours.
Are Australian sunscreens really better?
Many offer superior UVA protection and more comfortable textures, which can encourage better daily use.
What’s the best combination for sun protection?
Use a broad-spectrum SPF daily and wear UPF 50+ clothing—especially when outdoors for long periods.
Does UPF clothing replace sunscreen?
It doesn’t replace face sunscreen but adds full-body protection where people often forget to apply (arms, chest, shoulders). Learn more in our post titled Do UPF Shirts Really Work?
