Glycerin

Glycerin is a naturally occurring compound widely used in skincare, personal care, pharmaceutical, and food products. Also known as glycerol, it is a clear, odorless liquid valued for its ability to attract and retain moisture, making it one of the most commonly used ingredients in modern cosmetic and wellness formulations.

Today, Glycerin is found in a wide variety of products, including moisturizers, serums, soaps, lotions, oral care products, and certain dietary supplements. Its excellent compatibility with other ingredients has made it a staple component in formulations designed to support skin hydration and everyday personal care.

Glycerin Ingredient Guide

What It Is

Glycerin, or glycerol, is a naturally occurring sugar alcohol that can be obtained from both plant and animal sources. Most modern cosmetic and personal care products use plant-derived glycerin, which is commonly produced from vegetable oils such as soybean, coconut, palm, or rapeseed oil.

The ingredient is highly valued because it functions as a humectant, meaning it attracts moisture from the surrounding environment and helps retain water on the skin's surface.

After purification, glycerin becomes a clear, colorless liquid suitable for use in a wide range of cosmetic, pharmaceutical, and wellness products.

What It Does

Glycerin is commonly included in products designed to support skin hydration and maintain the skin's natural moisture balance. Its moisture-binding properties help keep the outer layer of the skin feeling soft, smooth, and comfortable.

Because of its versatility, Glycerin is frequently used in facial care, body care, nail care, and oral care products. It also helps improve the texture and consistency of many formulations, allowing other ingredients to spread evenly across the skin.

Products containing Glycerin are intended to support normal skin care and everyday hydration rather than diagnose, treat, cure, or prevent any disease.
