Glycerin is the commercial name of glycerol which contains 95% of glycerol in it. Glycerin cannot be used interchangeably with glycerol. Glycerin is a less pure form of glycerol.
Glycerol is most commonly used for constipation, improving hydration and performance in athletes, and for certain skin conditions. It is also used for meningitis, stroke, obesity, ear infections, and other conditions, but there is no good scientific evidence to support these uses
You could also make a homemade facial cleanser by mixing half a cup of water with one and a half tablespoons each of glycerin and cornflour in an ovenproof glass jar. Bring the mixture to a boil till the mixture looks clear. After the mixture has cooled, apply a little on moist skin and wash out with warm water.
