I've been using Skin+Me since last January, mainly to address some pigmentation spot issues. I worked my way up to 0.05 strength tretinoin but had to drop back down to 0.04 due to dryness and irritation.
But I can't see a huge improvement in pigmentation - I think it's slightly better but I still have some dark spots that I would've expected to have lightened by now. I'm religious about sunscreen too.
It isn't cheap so do I just give up and go back to the retinol (as opposed to rerun-A) I was using before? Or should I give Dermatica a go? I notice their formulas use hydroquinone which I know is the gold-standard for improving pigmentation spots.
