Glycerin
Glycerin, also known as glycerol, is a common ingredient in cosmetics and personal care products. It's a colorless, odorless, viscous liquid that is sweet-tasting and non-toxic.
Key uses of glycerin in cosmetics include:
Humectant: Glycerin is a powerful humectant that draws moisture from the air into the skin, helping to keep the skin hydrated and maintain its smooth appearance.
Skin-Protectant: By attracting water to the skin, glycerin helps maintain the skin's natural barrier against harmful substances and environmental conditions.
Texture and Stability Enhancer: Glycerin is often added to cosmetics to improve their texture, making them smoother and easier to apply. It also helps products maintain their stability over time.
Skin Conditioning: Glycerin can soften and soothe the skin, which is why it's often found in products like lotions, creams, and cleansers.
Carrier for Other Ingredients: In some products, glycerin is used as a delivery system to help other ingredients penetrate the skin more effectively.
Glycerin is generally safe and well-tolerated by all skin types, including sensitive and acne-prone skin. However, individual reactions can vary, and a small number of people might experience skin irritation or sensitivities. In such cases, it's a good idea to patch test new products before applying them all over the skin.
Synonyms for glycerin in cosmetics include glycerol, 1,2,3-Propanetriol, glyceritol, glycyl alcohol, and E422. It may also be part of compound ingredients like Caprylic/Capric Triglyceride or Glycereth-26.
As with all skincare ingredients, it's recommended to consult with a dermatologist if you have any concerns about a particular ingredient or product.
