[Misc] Has anyone successfully healed a damaged skin barrier, and if so, how?

To sum it up, I basically spent years nuking my skin with harsh cleansers, toners, DIY masks with lemon juice... Pretty much committed every skincare crime you can think of because I didn't know any better.

My skin is now always red and if I don't manually add moisture back or product, it becomes rough and dry within 2-3 days.

Right now, my routine is super gentle, soothing, minimal: ie. Gel cleanser, face oil, Hydrosol, and SPF. Although I have seen great improvements, my skin is still always red.

Wondering if anyone has ever successfully fully reversed a damaged skin barrier and TEWL? And if so, how long did it take and what was your routine?

Thanks.
