I have a small scar on my stomach I'm trying to hide for a holiday. I tried to henna but it wouldn't stay on the scar tissue, and didn't stain. I want to do a glitter tattoo using nail glue and body glitter. I know nail glue isn't good for your skin but I'm desperate. I'm going away for three weeks in the sun and in the sea/ water. Before I do it, is there any other ways I can cover it? Please help soon! I'm leaving tomorrow.
