Le Marsouin is a young French brand created in 2019 by Benjamin. His bet? Make a range of treatments for men based on marine algae. And what's more, seaweed from Brittany. Originally from Normandy, Benjamin believes a lot in short circuits. That is why he opted for a nearby laboratory, located in Ile-et-Vilaine for the design of Le Marsouin products. In this new brand, we find quality care, COSMOS certified by ECOCERT and labeled COSMEBIO. The range is intended to be gentle on the skin, since all preservatives, allergens, endocrine disruptors and other “bullshits” have been banned from the formulations. 1% of the brand's turnover is donated to the Wings Of The Ocean association, a French association that works for the depollution of the coastline.
