Kind: research · Impact: low

## In brief

- Researchers report tiny biodegradable spiked particles mixed into creams create microscopic openings in skin.
- The particles reportedly increased delivery of a tested skincare compound nearly 37-fold, without injections or patches.
- The approach is described as aimed at getting topical medicines through skin more effectively.

## Why it matters

It shows a formulation-based route to improve how much drug reaches the body through the skin, which could matter for topical treatments; the sources describe it as a lab-stage finding.
