I stand corrected!
I was using the BioSource cleanser together with the AquaSource hydrating gel. My face was less tight than the Bihada Ichizuko cleanser, less of that “squeaky tighty” clean. The hydrating gel has a nice smell, and absorbs pretty fast into the skin as well. I used it in generous amounts as I wanted to finish up the samples. Shall try the moisturiser at night!
