Summer self tanners. You can get some brands in a choice of for fair-medium skin tone or for medium to olive/dark skin tone etc.
So which has more of the active ingredient? ie which would give a deeper result?
I say - for a deeper result get the medium-olive option because it must have more 'tan' in it. An olive skin can 'take' a deeper colour.
My friend says - for a deeper result get the fair-medium option because it must have more 'tan' in it. To make you equally tanned as someone with olive skin.
Who's right?
