I was allergic to every sunscreen on the market from when I was 12 and got a bad allergic reaction to one (face swelled, such a rash) but then the mineral ones eventually got better (that’s what I mostly use) and the Korean ones got available here (those are amazing, gentle and effective) so for the last 30 years I have been able to screen and my skin is good enough people comment & ask for my routine. In my early 20s, like you, there was a period I could only use water, or a little pure jojoba.
So I think to some extent you can recover it. Retin-A and sunblock every day.
A hat helps too, every inch of hat brim helps.
