In my 20s I bought the Clinique three - the toner didn't seem to do anything. I stopped bothering with it
In my 40s I started using Liz Earle so got the toner as part of the kit. It didn't appear to anything other than smell synthetically like baby lotion. So I stopped buying it.
A couple of years ago I tried alpha gold (maybe I've got that wrong) - and then I remember why I stopped - it did nothing.
And now I'm about to finish up a bottle of Elemis toner and unless someone tells me what it's supposed to do, I won't buy again.
Gimick or useful? If useful which one works and what does it do?
