Emollients are key ingredients in skincare, used to soften, moisturise and improve the texture of the skin. They work by forming a protective layer on the surface of the epidermis, which helps to retain moisture and prevent dryness. These agents are often present in creams, lotions and balms to provide added comfort and maintain soft, supple skin.

FAQ about emollients
How do emollients work?
The emollients act by forming a thin layer on the surface of the skin, which prevents water loss and improves the softness and elasticity of the skin. In addition, emollients can penetrate into the epidermis to hydrate the skin in depth.
Which emollients are commonly used in formulation?
Vegetable oils, squalane and fatty acids are among the most widely used emollients in cosmetic formulation.
Do oily skins also need emollients?
Yes, oily skin also needs emollients to remain soft and supple. This type of ingredient is found just as much in creams for oily skin as in those for dry skin.
Emollient and moisturising: is it the same thing?
No, although both contribute to skin hydration, emollients focus primarily on softening and protecting the skin, whereas moisturisers directly add water to it.
Can emollients cause blemishes?
Certain emollients can indeed block the skin’s pores and contribute to the appearance of spots. However, it should be noted that the concept of comedogenicity has been little studied and varies greatly from one individual to another.
What is the difference between emollients and film‑forming agents?
Emollients and film‑forming agents both create a protective layer on the surface of the skin to prevent water loss, but film‑forming agents have a greater occlusive potential. Conversely, emollients can penetrate into the stratum corneum, unlike film‑forming agents, and exert a deeper moisturising effect.
Are emollients useful in cases of eczema?
Yes, they are essential for restoring the skin barrier and reducing the dryness associated with eczema.
How often can emollients be used?
Emollients can be used on a daily basis.
Are emollients natural?
Some are, such as vegetable oils, but there are also synthetic emollients.
Do emollients improve the skin barrier?
Yes, they help to strengthen the cohesion of lipids in the stratum corneum.
