I'm 34 and something shifted this year that I can't explain. The lines on my forehead are deeper, the ones around my mouth are more prominent, my overall skin just looks more tired than it did even last year. Nothing in my life changed dramatically like same diet, sleep

I've been on retinol for 2 years so it's not like I've been doing nothing, starting to wonder if retinol alone just isn't enough at a certain point and I need to think about this differently. Has anyone else experienced a sudden shift like this and figured out what was behind it? more importantly what helped?
