What was studied?
Anionic and cationic liposomes were compared for size, bilayer properties, encapsulation and selected enzyme-assay responses.
What did the researchers report?
The researchers obtained stable carrier systems with differing encapsulation efficiencies. Elastase inhibition was observed, while tyrosinase activity did not change significantly.
What are the limits?
An enzyme assay is not a clinical wrinkle or pigmentation trial. Carrier composition and loading conditions are part of the tested material and cannot be ignored.
