Hi,
I've been using The Ordinary retinoid 2% and lactic acid 5% for about 6 weeks. Really like both, so decided to put things up a notch. Have just ordered 5% ret and 10% lactic.
I was wondering how other people have got on with these strengths. I've had absolutely no issues with the weaker ones, but am a bit worried things might go pear-shaped!
Thanks,
Ags
