Glycerin In Skincare - Why Is It There and What Does It Do?
January 04, 2023
Have you noticed glycerin being in a lot of your skincare products? Here we'll breakdown what vegetable glycerin is, how it benefits skin, and reasons why it can be safe and beneficial for acne prone skin!
What Is Vegetable Glycerin?
Glycerin is a type of water soluble sugar alcohol - but don’t let the 'alcohol' part of the description fool you. Glycerin is actually commonly used as a humectant - meaning it draws water in.
It is a clear, odorless liquid that is derived from vegetables like soybean, coconut, or palm. It’s possible that glycerin can be derived from animal products too, but vegetable glycerin specifically is plant based.
Glycerin has a thick, almost maple syrup-like consistency and can feel a little tacky on the skin in high concentrations.
Why is glycerin in my skincare?
The reason why a lot of cosmetics or skincare products have vegetable glycerin in them is because they serve several purposes in skincare products and have some great skin benefits as well!
Glycerin can be mixed into products to keep ice crystals from forming in them, and it also works great at keeping products from drying out, or as a way to bind different types of ingredients together in the formulation.
How Does It Benefit Skin?
Vegetable glycerin is classified as a humectant. That means that it can draw moisture into the skin and it will keep the water there.
Glycerin is able to pull water from the air and also from our body to add more moisture to the skin barrier to keep skin healthy overall.
Keeping the skin barrier healthy is key to reducing inflammation and it may help prevent acne breakouts too as there is evidence a damaged skin barrier causes more acne.
There are studies showing that applying a moisturizer with glycerin can increase the skin hydration level after 10 days. There’s also some evidence that glycerin works better and increasing the skin’s moisture levels even better than hyaluronic acid and silicone combined! Pretty impressive if you ask me.
Is Glycerin Good For Acne Prone Skin?
Yes! Glycerin is one of the best ingredients for acne prone skin. Glycerin is considered non comedogenic. It is a non irritating ingredient that is well tolerated by almost everyone. Although pure glycerin may feel thick and syrupy, it is usually diluted into a formula in a skincare product, so it won't have a thick feel and shouldn't clog your pores.
Since glycerin helps to hydrate and strengthen the skin, it can be beneficial for acne prone skin where skin is commonly dry, or inflamed from various acne medications and the acne itself.
Products with glycerin in them can help act as a natural hydrating barrier against irritants in the environment.
How To Use Vegetable Glycerin For Skincare
The good thing is that vegetable glycerin can be found in plenty of formulated skincare products so you’ll get extra benefits from glycerin and the additional ingredients too.
To get the most hydration out of your skincare product containing glycerin, have damp skin before putting on your serum, lotion, or moisturizer. That gives the glycerin some extra water to hold onto and hydrate your skin with.
If you want to use pure vegetable glycerin, make sure you dilute a few drops of vegetable glycerin with some water first. Pure glycerin could pull too much water from the skin and cause an opposite effect and the sticky effect from pure glycerin could leave acne prone skin feeling greasy.
Vegetable glycerin is safe to use all over the body and on the lips.
