It's an extremely buffering product, I would say to buffering maybe even stripping. It contains lye and essential oils. I decided to buy and test it as my skin can handle lots, and I was really excited to have a bar of face wash so the travelling is more convenient.
I use it when I really need a deep clean and quickly follow up with toners as it is stripping indeed. Surprisingly great when I need to wash my makeup sponges. I like it from time to time, especially for travelling.
