I've only started using this stuff recently (the limes version - coral (rose) is a little girly for me). I must say it really is the bees boll*cks!
Doesn't seem to make too much difference to the lather with cream but you definitely feel a difference.
What really astounded me was the difference it made to my lathers from soap (TOBS lavender).
I make lather from an almost dry brush and soap so it has lots of water. This has given me good results before but with the skin food it really fells like I'm using a cream. Very impressed indeed!
