Questions about our formulas? We answer you!

Florent Mas, R&D DIRECTOR OF SOREDEC LABORATORY.

ARE OUR FORMULAS VEGAN?

YES, in the vast majority of cases. In our entire product offering, only two raw materials of animal origin are used: collagen (INCI: collagen) which is derived from co-products from the fishing industry; beeswax derivatives (INCI: synthetic beeswax). There are now only 8 non-vegan Sothys formulas!

HOW DO WE MANAGE CONTROVERSIAL INGREDIENTS?

To minimise the use of certain controversial ingredients, we are constantly looking for alternatives to silicones, phenoxyethanol, sulphates and BHT in our future formulas.

DO WE USE SYNTHETIC INGREDIENTS?

Yes, when they are essential to the nature of the formula, such as certain fragrances, certain molecules for their anti-ageing effectiveness in particular, and sun filters.

HOW DO WE ENSURE THAT OUR FORMULAS ARE WELL TOLERATED BY THE SKIN?

Before being placed on the market, all our formulas undergo numerous tests, including a cell culture evaluation, clinical tests under the supervision of dermatologists, and a safety assessment performed by an external independent toxicologist.

“Research and development are our key priorities for beauty that respects the skin and is committed to protecting the environment.”
