Glycerin in cosmetics: the benefits and how to use it

Glycerin, also known as glycerol, is a colorless, odorless liquid that is used in a variety of skincare and cosmetic products. Its moisturizing properties make it a popular ingredient in lotions, creams and serums. In this article, we'll explore the benefits of glycerin in cosmetics and provide tips on how to use it effectively.

Benefits of glycerin in cosmetics

Glycerin is a popular ingredient in cosmetics due to its many skin benefits. Here are some of the main benefits:

  • Moisturizer: Glycerin is a humectant, which means it has the ability to attract water molecules and hold them. This makes it an excellent ingredient for moisturizing the skin. When applied to the skin, glycerin draws moisture from the air and helps keep the skin hydrated. It is the main ingredient of a good moisturizer !
  • Non-irritating: glycerin is non-irritating and non comédogène, meaning it won't clog pores or cause irritation. This makes it a great option for people with sensitive skin or those prone to breakouts.
  • Improves barrier function: glycerin can help improve skin's barrier function, which is the skin's ability to protect itself external factors such as pollution, UV rays and bacteria. By strengthening the skin's barrier function, glycerin can help prevent moisture loss and maintain healthy, hydrated skin.

How to Use Glycerin in Your Skincare Routine

There are several ways to incorporate glycerin into your skincare routine. Here are a few tips:

  • Add glycerin to your moisturizer: if your cream does not moisturize you enough (if the product is good, this should not normally happen, we have a more direct solution at Mastel), you can add a few drops of glycerin to your moisturizer to boost its moisturizing properties. Simply mix a small amount of glycerin into your moisturizer and apply as usual.
  • Use a glycerin-based toner: Look for toners that contain glycerin as one of the main ingredients. These toners can help hydrate the skin and prepare it for the next steps in your skincare routine.
  • Create a masque DIY facial with glycerin: You can create a moisturizing facial mask by mixing glycerin with other moisturizing ingredients such as honey or aloe vera gel. Apply the mask to your face and leave on for 10-15 minutes before rinsing.
  • Use products with glycerin as the main ingredient: Look for skincare products that have glycerin as the main ingredient, such as lotions, creams, and serums. These products can help keep your skin hydrated and healthy.

Precautions when using glycerin in cosmetics

Although glycerin is generally considered safe for use in cosmetics, some precautions should be taken into account:

  • Avoid using glycerin on broken or irritated skin: Glycerin can sting or cause further irritation if applied to broken or irritated skin. If you have open wounds, cuts, or burns, avoid using products containing glycerin until the skin has healed.
  • Do not use high concentrations of glycerin in humid environments: although glycerin is an excellent moisturizer, it can also absorb moisture from the air. In high humidity environments, using products with a high concentration of glycerin can cause skin to feel overly hydrated and sticky. If you live in a humid environment, try using products that are low in glycerin.
  • Check for allergies: As with any skincare product, it's possible to be allergic to glycerin. If you notice redness, itching, or swelling after using a product containing glycerin, discontinue use and consult a dermatologist.

Other uses of glycerin

In addition to its use in cosmetics, glycerin has many other practical applications. Here are some other uses of glycerin (for general culture):

  • Foods and Beverages: Glycerin is used as a sweetener in foods and beverages and can be found in many processed foods, baked goods, and beverages.
  • Pharmaceutical: Glycerin is used as an ingredient in many medications and supplements because it can help improve the absorption of active ingredients.
  • Industrial: Glycerin is used in many industrial applications, such as the production of soaps, detergents and plastics.
  • Personal care: Glycerin can also be found in many personal care products, such as toothpaste, mouthwashes, and hair care products.

To conclude, glycerin is a versatile and beneficial ingredient in cosmetics that can help moisturize and protect the skin. By following the tips outlined in this article and taking the necessary precautions, you can incorporate glycerin into your skincare routine and reap its many benefits. Whether you're using it in your favorite moisturizer, creating a DIY face mask, or exploring its many other uses, glycerin is a powerful ingredient with many practical applications.
