As the third-most frequently used ingredient in cosmetics, chances are you’re already using something containing glycerin. But you may be wondering what glycerin does, and why it’s such a major component in beauty products.
It’s reported that glycerin has hydrating properties, working on the outer layer of skin. It can also boost your skin’s barrier, protecting it against stressors as well as providing a self-healing boost.
Also known as glycerol, it’s an ingredient that can be found naturally in plant compounds. When it comes to your beauty products, it works as a humectant, meaning it draws water through the skin layers, while preventing water from evaporating straight back out.
Because of its water absorbing and retaining powers, it’s often used to relieve dry skin. You’ll find glycerin in cosmetic products that range from soaps, to face masks, to your daily moisturiser. And thanks to its moisture attracting and retaining properties, glycerin can help you to keep your skin hydrated and dewy.
