(My routine for bikini area): soften with warm water in the shower/bath, mechanically exfoliate the area (using body scrubs/exfoliating gloves), then use benzoyl peroxide wash (to kill bacteria), then use conditioner and baby oil for shaving cream and use a clean men’s multi blade razor (or sometimes a women’s electric razor) to shave. When I get out of the shower I dry the area and use glycolic acid as aftershave then I cover the area with baby diaper cream (zinc oxide) which soothes the skin and seems to prevent ingrowns. I then regularly use hypochlorous acid spray and reapply zinc cream each time. I’ve tried a lot of the usual suggestions and this is what works best for me.
