These scenarios pose a very low risk of HIV transmission. It is extremely rare for Hep C to be transmitted through household items like makeup and rare for it to be transmitted through tweezers but it’s just good hygiene practice to not share these personal items if you’re able to. Things like razor blades for shaving and tweezers can possibly lead to blood to blood contact between people and thus there is an increased risk for acquiring blood borne illnesses, but it’s really unlikely that you will acquire HIV or Hep C in these ways.
