Glycerin

Glycerin – A classic moisturizing ingredient in cosmetics

Glycerin, also known as glycerol, is a naturally occurring compound that is colorless, odorless, and mildly sweet, typically found in a thick liquid form. With a chemical structure containing three hydroxyl (–OH) groups, glycerin has strong humectant properties, is highly water-soluble, and safe for the skin. These characteristics make it one of the most commonly used moisturizing ingredients in the cosmetics and personal care industry.

🌿 Key Benefits of Glycerin

1. Moisturizing and Hydration Lock

Glycerin is a powerful humectant, capable of attracting water from the environment and deeper skin layers to hydrate the outermost layer (epidermis). As a result, it:

• Helps maintain the skin’s natural moisture balance

• Softens and smoothens the skin, reducing dryness and flakiness

• Enhances skin elasticity and helps slow down the aging process

2. Restores the Skin’s Protective Barrier

Glycerin helps regenerate the skin’s lipid barrier, making the skin stronger and more resilient against environmental aggressors such as pollution, bacteria, and UV rays.

3. Supports Treatment of Dry and Sensitive Skin

Products containing glycerin are often well-suited for dry, inflamed, itchy, or cracked skin. Glycerin has soothing and skin-repairing properties, helping to regenerate skin cells without causing irritation.

• In cosmetics: Found in moisturizers, serums, toners, facial cleansers, face masks, lip balms, and more.

• In industry: Serves as a humectant in food, a lubricant, and a solvent for active ingredients.

⚠️ Precautions When Using Glycerin

• Glycerin should be used in combination with water or other hydrating agents, as using it in pure form or in dry environments may cause it to draw moisture from the deeper layers of the skin, potentially leading to dryness.

  • Store in a cool, well-ventilated place, away from direct sunlight.

  • Common usage concentration in cosmetics: 2–10%, depending on formulation purposes.
