I've been staying at my friend's for the weekend and she uses Superdrug Optimum Advanced Firm & Lift Perfecting Serum. I tried it today and it's made my skin feel amazing - really velvety. However, I can't find it on the Superdrug website. There is a serum in the grape Optimum range which sounds similar - is it the same one but repackaged, or was the old one discontinued entirely? The current one also seems much more expensive! I'll be gutted if it's not the same though.
