Charlotte Tilbury Wonder Glow - any cheaper alternatives?

[Whochangedmyname]

Bought this 9 months ago and it is one of those rare products that I think actually does make a difference. Coming to the end of it and am wondering if there is a cheaper alternative to try or if I should just find the money to replace it.

What is it

It's basically a skin illuminator with light reflecting particles. Revlon do one in different shades, and No.7 do similar. I think a lot of the brands do them actually, just a case of having a look in Boots/Superdrug!

Have you tried the Rosie H-W one in M&S?
