What it means
A compound can work in a dish and still have poor bioavailability in people. Topical ingredients must get past the skin barrier, and oral ones must survive digestion and liver processing.
Formulation can change bioavailability, which is one reason the same ingredient can perform differently between products.
Also known as
- absorption
- bioavailable
- systemic availability
