Approved by skin professionals, this ingredient has no equal to hydrate the epidermis. Zoom on an asset that we do not speak enough, however used for centuries.
Without even knowing it, you have probably already used it for years. This asset present in many creams has no equal to hydrate the skin. And for good reason: it is part of the family of the mums! Quésaco? These are key ingredients in the products since they allow water to attract and retain it where our face needs it most: the external part of the epidermis. “”By capturing environmental water or deeper layers of the skin, they help maintain optimal hydration, which is essential to have soft, flexible and elastic skin“, Writes Dr. Chahinez Filali in his work” My Skincare Code “.
According to several sources, glycerin has been used since 18e century already. If we find it first in the composition of drugs, it quickly takes a place of choice in the formulas of beauty products: first in the soaps, then in the creams and care for the face thanks to its moisturizing virtues. “”Glycerin, also called glycerol, is a natural compound present in animal and vegetable fats“Explains Dr. Sophie Momen, dermatologist at the American version of Vogue.”However, she said, most cosmetic glycerins are of plant origin.“In addition to moisturizing the skin in depth by attracting and holding the water there for a long time, it improves the elasticity of the epidermis. It smooths the irregular texture, relieves dryness and promotes skin healing. Once applied, it even leaves a slight protective film which provides a feeling of softness and flexibility.
In short, a real nugget to which we no longer pay attention as it is used in beauty products, without being put forward compared to its cousin: the very known hyaluronic acid. Yet, “Glycerin is a versatile and secure choice that offers equally, or more effective results for deep hydration“, Writes Dr. Filali. In order to fully benefit from the benefits of glycerin, however, we must respect certain conditions. The first? Do not exceed a concentration of 10%, since it then loses its moisturizing properties and promotes, on the contrary, water loss.
Finally, Dr. Chahinez Filali recommends in his book to combine glycerin with an occlusive agent or an emollient (petroleum jelly, ceramids, squalane oil, beeswax …) which “Seal this water in the skin and strengthen the skin barrier.“”
