Glycerin (also called glycerol) is a naturally occurring alcohol compound and a component of many lipids. Glycerin may be of animal or vegetable origin
- Glycerin has a long history of safe use, and is considered non-allergenic and suitable for breakout-prone skin
Glycerin is hygroscopic. What that means is that glycerin can draw moisture from the air around us and help keep that moisture in skin. Another word for hygroscopic is humectant
Research has shown that glycerin mimics what’s known as skin’s natural moisturizing factor (NMF), which is why it’s compatible with all skin types, of all ages
Replenishing skin’s NMF is important because it becomes depleted as we age, are subject to environmental exposure, and use irritating ingredients like denatured alcohol
Glycerin’s benefits also include:
- Helping to shield skin from environmental sources of irritation.
- Working with emollients and oils to make dry skin feel amazingly soft and supple.
- Fortifying and strengthening skin’s precious moisture barrier.
- Enhancing the penetration of other ingredients into skin’s uppermost layers.
- Improving skin’s resiliency and youthful look
- Glycerin is also involved in the transport and activity of aquaporins in our skin’s surface. Aquaporins are proteins that channel the flow of vital hydrating substances (including water and glycerol) to skin’s uppermost layers. They play a key role in maintaining skin’s moisture balance, keeping it feeling smooth and comfortable even in drier climates
