Does this new sunscreen stay safe and strong all day?
In vitro safety evaluation of sunscreen formulation from nanostructured lipid carriers using human cells and skin model.

Surprising Findings
The sunscreen showed no phototoxicity despite UV exposure up to 10 MED.
Many sunscreens, especially chemical ones, become toxic when exposed to UV light—this one didn’t, which contradicts common concerns about photo-degradation products.
Practical Takeaways
If you’re indoors most of the day with minimal sun exposure, this sunscreen may offer longer-lasting protection without frequent reapplication.

Claims (6)
After 8 hours, about 28% of one UV filter and 40% of another slowly leaked out of the sunscreen, meaning it releases the active ingredients slowly over time.
When tested on human skin cells and skin models, this sunscreen didn't kill cells or cause irritation, so it might be gentle on skin.
When exposed to UV light in the lab, this sunscreen didn't make human skin cells become toxic or die, meaning it doesn't cause harmful reactions when hit by sunlight.
This sunscreen stayed effective even after being exposed to strong UV light — equivalent to 10 times the amount that would normally cause sunburn — without breaking down.
This sunscreen uses special fat-based nanoparticles and a plant-derived compound to help the sunscreen stay stable and not get absorbed into the body.
