Following dessert have a toner for the skin (10)
I believe the answer is:
aftershave
'a toner for the skin' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'following dessert have' is the wordplay.
'following' is a charade indicator (letters next to each other).
'dessert' becomes 'afters' (afters can mean a dessert course).
'afters' put next to 'have' is 'AFTERSHAVE'.
Can you help me to learn more?
(Other definitions for aftershave that I've seen before include "alcohol to splash on, say" , "liquid splashed in bathroom" , "Fragrance" , "Soothing spirit" , "I'm slapped on the face" .)
