Science
Mechanism of Action
This non-polar saturated hydrocarbon creates a breathable, hydrophobic barrier on the skin's surface. By forming this thin occlusive film, it physically prevents transepidermal water loss (TEWL) and integrates into the intercellular spaces of the stratum corneum to smooth texture and restore barrier lipid functionality.

Key findings
- 01 In vivo testing at 1-5% concentrations demonstrated a measurable reduction in TEWL and a significant increase in cutaneous hydration over a 28-day period.
- 02 Comparative rheological studies show that at 2%, this ingredient provides superior emulsion stability and more uniform droplet distribution than isohexadecane.
- 03 High-concentration microemulsion research indicates the alkane achieves exceptional skin adhesion and spreadability without leaving a heavy or oily residue.
Transparency
Dusting Analysis
While often used as a functional texture enhancer, its clinical benefits for barrier repair are realized at levels between 1% and 5%. Formulations containing less than 1% may be utilizing it solely for solvent properties rather than skin-replenishing benefits.
The Formula
