I picked this up by rushed accident thinking it was the expert foaming wash recommended by a very knowledgeable male Youtube MUA. Luckily, this was on sale and dirt cheap, must have been less than 5e. Also: it's brilliant!
I have acneic, very oily skin which needs a good clean but SLS, alcohols and clay have the negative effect of really drying me out when used daily. I keep this in the shower and use it to ensure no shampoo/conditioner residue has fallen onto my face. I also pull it out whenever I have sensitivity issues. Just wonderful. I'll be going back to stock up.
