Please, for the love of all that is clean, do not use bleach, nail polish remover, or rubbing alcohol on your face. These are for stains on fabric or hard surfaces—not your delicate skin. You want to remove blood, not add chemical burns to the mix.
Also, avoid scrubbing with abrasive sponges like loofahs or scrub brushes. Your skin isn’t a dirty pan. Be kind to it, even when it’s covered in fake gore.
If you have sensitive skin, test any new product on a small patch first. No one wants a red dye stain and a rash. That’s just overcommitting to the horror theme.
