Allies of Skin Molecular Silk Amino Hydrating Cleanser (100ml for £39)
I have zero complaints towards the quality of this product. Yes, it doesn't foam, but it still works well as a cleanser -- it removes my mascara really well too. Non-stripping. However, because of its non-foaming nature, I noticed that I inadvertently use more product. Furthermore, of course, the price for 100ml of cleanser is indeed ridiculous. Considering its a product that you don't have on your face for more than 2 minutes, not sure whether all the "good" ingredients actually do anything beneficial to the skin in that time.
