[Acne] Wtf is wrong with my skin? Dry, sensitive and nothing works

It could be demodex to me. If you Google image search "demodex face" you can find some examples that look similar (although many examples are much worse than yours). It can flare up from sun exposure and other things so that might be why it can come or go. Basically, everyone has demodex but some people have more than others and some people have skin that is more sensitive to it than others. The treatment is soolatra (needs a prescription in the US) or tea tree oil. You must dilute the tea tree oil with another oil like jojoba.

Now as for redness from drinking, sorry to say but that is probably just genetic and the only cure is to limit your drinking.
