I've tried gradually building up my The Ordinary 2% Granactive Retinol over a period of weeks, but my skin still can feel tight and a tiny bit sore. To make matters worse I had a digital skin analysis today and it showed I now have increased redness 
My skin tends towards redness anyway, I don't want it to get worse! I have been careful to use a high factor SPF since using Retinol, but I'm wondering if it's doing me more harm than good? I have always been lucky to have a good, clear complexion and have minimal fine lines at 48, so maybe retinol isn't that necessary?
