The vape juice in a Geek Bar Pulse device is a mixture of two primary ingredients: propylene glycol and vegetable glycerin. VG is thicker than PG and produces large clouds of vapor. However, VG can’t deliver a strong throat hit as PG. That’s why high-VG e-liquids are popular among people who wish to avoid the harshness of propylene glycol.
Vegetable glycerin is a substance derived naturally from vegetable oil. In vape juice, VG works as the base for many vaping products and helps create vapor when heated. As mentioned, VG is thicker than PG and gives you larger plumes of vapor combined with a smoother throat hit.
