I apply on the frist 3 days Bepanthen, I don´t know if you have it there, you wash it at least four times a day on these frist 3 days with water at normal temperature(not cold not warm), with some good soap with Ph neutral, then you aply the Bepanthen wait 15 minutes, take the excess, don´t leave the excess there, and cover the tattoo with some good non sticking bandages, and not plastic, the skin needs to breath also; after 3 days apply a normal hand loction or other type of loction, just pay atention to choose a good an very simple loction(no perfume or alcool).

I your case I would go to a pharmacie, and ask for some help frist, there are good products for help against infection.
Good luck

Try to get to a tattoo studio and ask there if you can learn something with then, thats the best and safe way, and don´t try anything on people too

I think that you should find by yourself the perfect phrase to carry on your body, you should put on your body only the kind of phrase that will give you strenght every time you see it, something personal, only yours.
Good luck
