I know nothing about them!
I'm the wrong side of 40 and recently started using, "The Ordinary" Granactive Retinoid 2% Emulsion.
Half a bottle in, my skin is looking good from it. But it didn't cost that much (£8 maybe? I can't remember) so I'm thinking there must be better retinoids on the market.
What percentage should I be going for at my age? Any product suggestions?
TIA
