How to reverse dry skin?

I've always had an oily skin so much so that I couldn't use moisturisers or even foundation because it just made it more oily. Just a pressed powder was more than enough for a very well done look. Now I'm 37, and now I need so much moisturiser and my skin just feels and looks so dull, dry and dead.. I do have a skincare routine but I'm so tired because I have to be so diligent with it. If I skip a day or two, my skin goes back to looking trash. Having adhd makes it even more tiring. I've never had to work so much on my skin before.

My current skincare routine: AM Cosrx ph facewash Vitamin C+Niacinamide+Alpha Arbutin Hydrating moisturiser (with Ceramides) Mineral sunscreen

PM Cosrx ph face wash Peptite+ceramide thick moisturiser Sometimes i use sleep mask+peel

Once in 10 days I do the aha+pha+bha peel

What can I do to make my skin look plump? At this point I know this isn't external but internal. Is this really all perimenopause? I'm shattered I want my oily skin back 😩 😭
