Abstract:Gamma−aminobutyric acid (GABA) presents several potential skin benefits, but its water−soluble nature poses challenges for effectively penetrating the skin to produce its effects. This research aimed to improve GABA’s skin penetration and availability by employing a nanoemulsion formulation, both with and without the aid of the penetration enhancer 1,8−cineole. Using a high−pressure homogenizer, an oil−in−water nanoemulsion was created, and its size and distribution were analyzed. The stability of these nanoem… Show more
