Bioderma's Sensibio H2O is a mycellar solution, something I looked up and researched extensively when I first bought the stuff and now can't remember anything about. Wait, ok you seriously want to know? Here's the definition from Wikipedia:
A micellar solution consists of a dispersion of micelles in a solvent (most usually water). Micelles consist of aggregated amphiphiles, and in a micellar solution these are in equilibrium with free, unaggregated amphiphiles. Micellar solutions form when the concentration of amphiphile exceeds the critical micellar concentration (CMC) or critical aggregation concentration - CAC, and persist until the amphiphile concentration becomes sufficiently high to form a lyotropic liquid crystal phase.
Got that? Here's what you need to know: it's a makeup remover, a toner, and a water-free cleanser in one. I started using it back when I had that ear infection and the doctor made it sound like if I got a drop of water in my ear I would spontaneously combust, and washing my face became an arduous chore. I'm better now, and get my ear wet all the time with no adverse effects, but I still use this every morning and most nights too.
Just pour some on a cotton pad and wipe it over your dry face and it removes all dirt and makeup effortlessly. Ok, maybe not effortlessly, sometimes it takes a few repetitions. But still, on those lazy nights when you just don't want to wash your face, or in the morning when there's not to much to take off, it's wonderful. Also, my very finicky skin is happier than ever before. I always use very simple and gentle cleansers (like this one or this one), but sometimes even those would leave my skin dry and tight. That is a thing of the past. And if the idea of not using water to wash and rinse your face freaks you out, you will still love this stuff as an eye makeup remover. It is magical I tell you, magical!
