I used to have really dry flaky skin, it would get so dry that I would even get chapping on my legs in winter. I started making my own MP soap and it seemed to get a lot better, and then I got really ambitious and started making CP soap where I controlled everything that went into the soap. It was like a religious conversion, I could never go back to commercial. Since then I can even go a few days without lotioning - I dont even ash. I like the moisturising effect and my skin has never been better. Maybe if you have naturally, self- moisturising skin, you could experience a 'build-up' of sorts, but the Crocodiles like me lurrrrrv the conditioning effects of handmade soap. That said though, to each his own!
