Glycerin is commonly found in moisturizing lotions because it is an effective humectant. Humectants are ingredients that attract water from the environment into the skin, helping to keep it hydrated. This quality is essential in lotions, as the primary goal is to provide moisture and prevent dryness. Glycerin's ability to bind moisture makes it particularly beneficial in maintaining skin elasticity and overall hydration, which is crucial for healthy skin.

Aloe Vera, Vitamin E, and Coconut Oil are also popular in skincare products but serve slightly different roles. Aloe Vera is known for its soothing properties and can help calm irritated skin. Vitamin E acts as an antioxidant, offering protection against free radicals and supporting skin health. Coconut Oil is praised for its emollient properties, providing a rich source of fatty acids that can help create a barrier to lock in moisture. While these ingredients are valuable in their own right, glycerin's specific function as a humectant makes it a standout choice in moisturizing formulations.
