Q Hi. Could you please tell me the difference between CozMedix 4% and SkinCeuticals 0.5? I see they each have a higher dose of 8% and 1.0 as well. Thanks!
A

Actually there is no difference the CosMedix Refine 4% is equal to a 0.5% retinol. I'm not exactly sure why the call it a 4%, many brands have different formulations but it is in fact equal to the 0.5% SkinCeuticals. Therefore the 8% is equal to the 1.0% SkinCeuticals.
