Vegetable Glycerin, also known as glycerol, is a clear, odourless liquid processed from plant oils. Vegetable glycerin is produced using an extraction process called hydrolysis. During hydrolysis, oils are placed under the combined force of pressure, temperature, and water. The ester bond breaks and causes the glycerin to split from fatty acids and be absorbed by water; at which point the resultant is further isolated by distillation to increase purity. Purified vegetable glycerin has a texture similar to an oil or syrup due to its organic molecular makeup, specifically, three hydroxyl groups.
Now that we got the science out of the way, let's talk what it can do for your beard. First and foremost, it is a great hydrator as it makes your skin absorb moisture from the air, giving you continuously soft and smooth skin while reducing dry and dull patches. This hydrating process does not just leave you feeling soft and smooth, it also fills the cracks left behind from dry skin, repairing the damaged skin under your beard. Vegetable glycerin has many benefits such as fighting free radicals and acting as an anti-ageing treatment, as well as helping with acne and blackheads. Also significantly beneficial for hair growth as it helps to hydrate and nourish the base of the hair, it increases hair length and thickness while eradicating dry, itchiness that may be present. Vegetable glycerin also helps to reduce split ends while helping to control frizzy, wild hairs, leaving your beard shiny and manageable.
