Ingrown & Razor bumps

Help!! I usually shave & did wax a few times but I haven’t had time to do wax so I just shave. Last time I shaved I got a razor bump & some ingrown hairs. I heard tree tea oil works but, I used it & now the ingrowns went away but I guess it was to strong & I didnt mix it good enough. Now I have these red spots as if the skin peeled off. Some are starting to heal but the others are very red. I dont know what to use and try make the redness go away. What’s some good tricks & tips anyone has to get rid of redness or ingrowns?
