The Claim

After 4 hours of exposure to any formulation containing bemotrizinol, including bemotrizinol-loaded nanostructured lipid carriers, no permeation of bemotrizinol through human skin was detected, indicating that encapsulation does not increase systemic absorption of this UV-filter.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

After four hours of skin contact with any product containing bemotrizinol, including those with encapsulated forms, no bemotrizinol was detected in the bloodstream, meaning encapsulation does not lead to greater absorption into the body.

See the scientific wording

No bemotrizinol permeation through human skin was detected after 4 hours of exposure to any formulation, including those containing bemotrizinol-loaded NLC, indicating that encapsulation does not increase systemic absorption of this UV-filter.

Why this might work

Bemotrizinol stays on the outermost layer of the skin because it does not dissolve well in water or move through the tight layers of dead skin cells, no matter if it is wrapped in fat particles or not.

  1. Study: Bemotrizinol-Loaded Lipid Nanoparticles for the Development of Sunscreen Emulsions

    Scientists tested whether putting the sunscreen chemical inside tiny fat particles makes it soak deeper into the skin. They found it didn’t — it stayed on top, just like when it’s not in the particles. So the nanoparticles help it work better without going where they shouldn’t.
