Science
Mechanism of Action
Cetyl Myristate operates through a dual-action pathway: first, it acts as an occlusive barrier, forming a breathable film that inhibits transepidermal water loss (TEWL) to sustain hydration levels. Second, it serves as a biomimetic penetration enhancer, temporarily modulating the lipid architecture of the stratum corneum to increase the bioavailability and absorption of co-formulated active ingredients.

Dusting Analysis
While often used as a secondary texture modifier at low levels, clinical data suggests that concentrations above 4% are required to unlock its functional benefits as a penetration enhancer and barrier repair agent.
