GLYCERIN: An essential moisturizing ingredient for the skin

SOLVENT ⎪ HUMECTANT ⎪ EMOLLIENT

What is glycerin?

Glycerin, also called vegetable glycerin when it is of natural origin, is an organic compound from the alcohol family, widely used in cosmetics for its moisturizing and softening properties. It is obtained by hydrolysis of natural fatty substances, such as vegetable oils (notably soya or coconut oil). In cosmetics, glycerin is prized for its humectant effect, that is to say its ability to attract and retain water, thus ensuring lasting hydration of the skin. Non-comedogenic and fragrance-free, it is suitable for all skin types, including sensitive and irritation-prone skin.

Glycerin is not used as an active ingredient but is present as an excipient in several of our products for its strong moisturizing power. 

It is produced during a saponification reaction (mixture of a fatty substance and soda which produces soap and glycerin). We always choose a vegetable oil or fat such as olive or coconut oil in order to respect the environment and our bodies. 

We chose it as a solvent in Clear skin detox elixir and as a humectant and emollient in our Body serums happy cycles and Anti-hair loss densifying hair as well as in the Gentle deodorant cream.

Where does glycerin come from?

Glycerin can be of natural or synthetic origin. Vegetable glycerin, extracted by hydrolysis of vegetable oils, is the form most commonly used in natural and organic products. The hydrolysis of fatty substances produces a pure, colorless and odorless glycerin, stable for use in cosmetics. Although glycerin can also be produced synthetically, the plant-based version is preferred for its skin benefits and biodegradability. It is used in many skincare products for its moisturizing, softening and protective properties.

Properties and active ingredients

Glycerin has several beneficial properties for skin and hair. Here are its main characteristics and actions:

1. Humectant : It attracts water into the skin, thus maintaining optimal hydration and helping to prevent dehydration.
2. Long-lasting moisturizer : Glycerin acts as a hydrating shield by trapping moisture in the skin, which helps maintain its elasticity and suppleness.
3. Softening : It provides a feeling of softness to the touch, making the skin smoother and softer.
4. Protective of the skin barrier : By strengthening the skin's lipid barrier, it helps protect against external aggressions and prevent water loss.
5. Soothing and non-irritating : Glycerin is gentle and non-comedogenic, making it a perfect ingredient for sensitive and redness-prone skin.

What are the benefits of glycerin?

Glycerin offers many benefits for the skin, thanks to its moisturizing, softening and protective properties. Here are the main benefits of this versatile and natural ingredient:

1. Intense and long-lasting hydration : Thanks to its humectant action, glycerin hydrates deeply, ideal for dry and dehydrated skin.
2. Protection of the skin barrier : By strengthening the skin's barrier, it prevents dehydration and helps the skin remain protected against external aggressions.
3. Softness and suppleness of the skin : It softens the skin by providing a smooth and silky texture, contributing to immediate comfort.
4. Soothing of irritations : By reducing redness and itching, it is ideal for sensitive or irritation-prone skin, helping to restore the skin's balance.
5. Versatility for hair care : Applied to hair, glycerin helps retain moisture, leaving hair soft and less prone to frizz.

How to consume glycerin?

Glycerin is primarily used topically in skin and hair care, although it is also used in some oral care. Here are the main ways to benefit from this ingredient:

• Moisturizing creams and lotions : Glycerin is often included in creams for its long-lasting moisturizing effects, perfect for maintaining hydration in dry and sensitive skin.
• Facial serums and gels : In serum or gel, it helps retain moisture and ensures intense hydration, ideal for skin seeking comfort.
• Soothing masks and treatments : It is often present in masks to soothe and moisturize, providing a restorative effect for damaged skin.
• Moisturizing hair care : In conditioners and hair masks, it improves the softness and suppleness of hair, while reducing frizz and providing shine.
• Oral products : In some oral care, glycerin is used for its humectant effects, helping to prevent dry mouth.

Note : Glycerin is well tolerated by all skin types, but in high concentrations it can cause a sticky feeling. For pure use, it is recommended to dilute it with water or incorporate it into creams. It is also suitable for hair, but it is preferable to use it in small quantities to avoid any weighing effect.

Any side effects?

Glycerin is generally well tolerated, but some side effects may occur, although rare:

1. Skin sensitivity : If pure glycerin is applied excessively, it may cause slight irritation or a sticky feeling. It is recommended to use it in dilution.
2. Desiccant effect in dry conditions : In very dry climates, glycerin can have a dehydrating effect, drawing water from the skin rather than from the surrounding air. It is best used with other moisturizing agents in these conditions.
3. Incompatibility with certain types of products : Glycerin may interfere with some active ingredients, reducing their effectiveness. It is best combined with emollients and moisturizing agents.
4. Mucous membrane sensitivity : In case of contact with eyes or mucous membranes, it may cause slight irritation. Rinse with plenty of water in case of accidental contact.
5. Weighting effect on hair : In hair care, excessive use can weigh down the hair and leave a greasy finish. Use it in small amounts in the hair.
