Hello, I have watched the Caroline Hirons retinol videos and I am currently using skinceuticals 0.3%.
The instructions say to work up to applying every other day - I've done that but my skin is really sore so have stopped using it so often. I'll go back to every 3rd day which I seem to tolerate better.
Am I supposed to just use at a level that my skin can tolerate without a reaction?
How long do I use it for? Do you just build it into your skincare routine or it a 6 week process that you do once or twice a year?
Thank you!
