Glycerin is in so many products that it is easy to overlook. But dermatologists often call it one of the most effective moisturizing ingredients there is.
What Is Glycerin?
Glycerin (glycerol) is a simple, clear, slightly sweet liquid. It is found naturally in the body and in plant and animal fats. Ours is plant-derived, and where a formula marks it ②, it is made using organic ingredients.
A 2008 review in the British Journal of Dermatology describes glycerol as a naturally occurring part of skin's own hydration system, and summarizes decades of research on topical glycerin.
What It Does for Skin
Draws moisture in. Glycerin is a humectant. It attracts water and helps hold it in the outer layer of skin, so skin feels soft and hydrated.
Supports the barrier. The same review reports that glycerin helps support skin barrier function and helps the outer layer stay flexible and smooth.
Feels comfortable. At typical levels, glycerin hydrates without heaviness or residue.
Helps formulas work. Glycerin also improves texture and spreadability in creams, serums, cleansers and makeup.
Where You'll Find It at True Colour Beauty
Glycerin is one of the most common ingredients across our range. A few examples: the Youthful Hydration Serum, the pH Balance Hydrating Toner, the Nourishing Rich Cream, the Caffeine Gel Booster and the Soft Skin Hand Cream.
It also helps makeup feel comfortable, including the Peptide Foundation and the Full Coverage Foundation.
How to Use It
You don't need to do anything special. Glycerin works in the background of your products. For the best hydration, apply humectant-rich products to slightly damp skin and follow with a moisturizer.
What the Research Doesn't Say
Glycerin is a supporting player, not a headline active. It won't brighten or exfoliate, but it helps nearly every routine feel more comfortable.
