SCIENCE AREA

We don't want to hide anything from you. This is why we have decided to disclose the percentages of our assets.

Our communication on social networks is also intended to be transparent, avoiding marketing misunderstandings as much as possible.


Julie, co-founder of Mastel, has also created a podcast on cosmetics industry, entitled "Les Souss de la Cosmétique". You can listen to it here.

An active ingredient is said to be objectified when it has clinical studies, which for a given percentage, prove its effectiveness.

For example, our hyaluronic acid has clinical studies using 0.1% to 0.5% in a cream and it has been proven that for 0.5%, the micro reflief (wrinkles) of the skin decreases by 66% after 28 days.

All of Mastel's active ingredients have been chosen in this way. They are all effective.
