Institut Esthederm is my absolute favorite French brand of skincare products. Before I moved to the US in 2012, most of my skincare routine was composed of Esthederm products, and I was regularly going to a day spa for facials with the brand's line. I would describe Institut Esthederm as a high quality professional brand (a lot of their products can only be purchased at salons after a skin analysis by a beautician - those are the ones that come in deep blue packaging if you already know the brand) with a unique philosophy: skin is a complex eco-system that should be protected and nourished with the elements it needs to thrive, rather than forcefully corrected through aggressive treatments. The idea is that skin should "know" what to do to be healthy, so it will reach that state if you provide it with the tools it needs to achieve it but refrain from interfering too much with its natural processes. It's my Esthederm beautician in France who convinced me to completely stop using mechanical exfoliation, i.e. abrasive scrubs, and that decision changed my life (at least my skin's life!).
Healthy skin starts with a gentle but efficient cleansing routine, and Esthederm has a range of cleansing products called Osmoclean. Being an avid user of micellar water (read more about micellar water here and here), I recently finished my bottle of Osmopure Face and Eyes Cleansing Water.
