Just started using this after previously using the 1% Retinol from the Ordinary. I absolutely love the consistency of it. Similar to the Cos de Baha Peptide serum, it has a viscous consistency that feel really soothing and looks like it might help counteract any side effects from using such a strong percentage of retinol. I can't comment on the long term effect it will have on my skin yet, but I can say for sure that it's a pleasure to use.
