The last bit of soap???

Question

I have heard this somewhere that you shouldn't use...the last bit of soap...when they are little or about the finish...some say that it is harsh on skin. ...or w.e..but i am not sure if this is a myth or real...and if it's real then wat is the reason behind it????

Thanks in advance for your answers...

Answer 1

I've not ever heard the before either.

I don't see what the  difference would be between that bit of soap and the rest of it.

Answer 2

i've never heard that before.. but i guess this makes sense for liquid soap or something as the most concentrated part of the product would sink towards the bottom..

i'm not 100% sure of course

but if you're really worried, maybe you can dilute it with water?
