Propylene Glycol is a clear, slightly viscous synthetic liquid that works to maintain adequate hydration levels, help active ingredients get into your skin, and keep products from melting in extreme temps (like if you leave your moisturizer in a hot car).
Propylene glycol works in skin care products as both a humectant and a conditioner. Basically, it helps you achieve two things you really want for your skin: Hydration and smoothness.
It can be an especially helpful ingredient if you’re constantly battling dryness, flaking, or gnarly rough texture.
Here’s a closer look at the benefits:
- Locks in moisture. Propylene glycol has humectant properties, meaning it draws water into your skin. It also works as a barrier to keep moisture in your skin, helping it stay hydrated.
- Protects the skin barrier. Propylene glycol’s humectant properties are thought to help protect and repair the skin’s outer barrier, which can be particularly awesome if you’re dealing with conditions like eczema or psoriasis.
- Helps skin look fresher. It’s pretty simple: More hydration and a happy, healthy skin barrier means your skin is more likely to have that glowy, dewy look.
- Helps other ingredients work better. Propylene glycol actually helps other ingredients make their way into your skin. Ultimately, they help that moisturizer or serum do its job so you can get the best possible results.
