One of the prime benefits of Glycerin is that it acts as a protective agent for the skin by creating a barrier between the skin and the elements that can harm it. Its brilliant rejuvenating and moisturizing properties are key to bright and luminous skin. Glycerin is also one of the key ingredients in several beauty products- from hair masks to hair sprays and moisturizers- you can name it. But using Glycerin in its pure form is best recommended as it cancels out the chances of any adverse side effects. Just like our skin, Glycerin benefits our hair in various ways too. Due to its ability to attract moisture from the air and lock it within the hair, Glycerin is used in several hair products. It nourishes and conditions the hair and scalp boosting hair growth.
