Eczema Treatment Care

Like a lot of other people on this site, I have metal allergies (Chromium, cobalt, and nickel) and i’m thinking about getting a tat. From the answers i see, having metal contact dermatitis doesn’t mean you’ll have a reaction to the tat – i’m just wondering if anyone’s had any experiences like mine. My allergies also extend to the point where I can’t wear eyemakeup with any of the above (especially chromium) as an ingredient, or my eyes will swell shut. I’m just thinking that if there’s such a negative reaction from having the dyes near my eyes, having it injected into my skin might not go so well. Thoughts? Experiences? Just looking to pick someones brain! Thanks!
