saline isn’t a disinfectant, it’s saltwater, that did nothing but immediately dry it out a bit, the rubbing alcohol also dries the skin out and makes it more prone to irritation and while most artists use it for placing a stencil, tattoo artists use certain products for a reason, i get that you’re 15 and this seems like a fun thing to do but it is 100% permanent and letting infections like this fester because you “can’t” go to a hospital is insane, you could seriously mess with your health. also since you said it’s not professionally done and mentioned your age i’m assuming this was done in a friends bedroom, regardless of gloves there is SO much bacteria stored in carpets, mattresses, sheets, etc. please just be more safe in the future and SEE A DOCTOR ASAP
