They ensure the stability, texture, and effectiveness of the products, while facilitating the absorption of active ingredients by the skin.

FAQ about excipients

What is the difference between an excipient and an active ingredient?
An active ingredient is a substance that has a direct effect on the skin, while an excipient supports the active ingredient without having its own biological effect.
Are all excipients synthetic?
No, excipients can be of natural or synthetic origin, depending on the formulation of the product.
Do excipients influence the shelf life of cosmetics?
Yes, certain excipients, such as preservatives, extend the shelf life of products by preventing the growth of microorganisms.
Can excipients alter the colour or smell of a cosmetic product?
Yes, certain excipients can influence the colour, smell, or texture of the final product.
Are excipients necessary in all cosmetics?
Indeed, without excipients, the active ingredients would be unstable, ineffective, or difficult to apply to the skin.
Can excipients interact with each other?
Yes, certain excipients can interact with each other, thereby affecting the stability or effectiveness of the product.
Can we be sensitive to excipients without being sensitive to active ingredients?
Yes, it is possible to react to an excipient while perfectly tolerating the active ingredients of a product.
How to identify excipients on a label?
