nanotechnology in sunscreens

How Do Nanoparticles Enhance Sunscreen Efficacy?

The nanoparticles in sunscreens provide several advantages over their larger counterparts:
1. Enhanced UV Protection: Nano-sized particles have a higher surface area-to-volume ratio, which improves their ability to scatter and absorb UV radiation.
2. Transparency: Unlike larger particles that can leave a white residue on the skin, nanoparticles are transparent, making the sunscreen more cosmetically appealing.
3. Even Distribution: Nanoparticles distribute more uniformly on the skin, ensuring consistent UV protection.
