How Do You Use Glycerin?

I ordered 4 ounces of anise oil to make springerle for Christmas next year. Instead, a pharmacy sent me 6 ounces of glycerin. I hate to waste it. Although I know it is often an ingredient in soap and moisturizers, I don’t know how to use it. So I looked it up.

Glycerin (C3H8O3 glycerol) is a compound derived from plants (from the triglycerides of such oils as soybean, coconut, or palm), animal fats (from beef or mutton tallow), or synthetic petroleum products (like propylene). It’s produced as a byproduct of making soap or splitting animal fats. Glycerin is also a natural ingredient found in fermented foods like beer, honey, and vinegar. If you are a science geek, go here for the in-depth details.

Suffice it to say, glycerin is a humectant (a substance that retains moisture, meaning it stops the loss of moisture), so it's often added to skincare as a moisturizer.

As a powerful moisturizer, glycerin needs to be diluted with water, rosewater, or mixed into lotions to prevent irritation and stickiness on the skin.

According to several sources, you mix 1 part glycerin to 2 - 5 parts water or rosewater and can put it in a spray bottle to use as a mist. Or you can add 1 - 2 drops of glycerin to one application of your regular face or body toners and lotions. You can also add 1 - 2 drops on a cotton pad along with a cleanser or toner to remove dirt on your skin, or you can add 1 - 2 drops to hand lotions, lip balms, or overnight face masks to boost their moisturizing properties.

Safety tips for using pure glycerin include: (1) Always dilute, (2) apply to damp skin, and (3) avoid excess. Too much of a good thing is rarely a good thing!

Frankly, I don’t think I’d go out of my way to buy pure glycerin, but now I know more about it, and sometimes we do have lotions or moisturizers that work well in warm seasons, but need an extra boost to work better in drier, colder seasons. In such cases, it sounds like a few drops of glycerin could enrich an already sitting-at-home moisturizer, turning it into the ultra winter moisturizer!

Aren’t we all the wiser? If you have experience using glycerin, feel free to share.
