Are you asking whether getting a tattoo will cause problems to your skin or aura? Or whether it'll improve your health in a magickal way? If it's the second one, I doubt it. Whatever you use for a magickal working needs to be programmed with your intention, and still not just a tattoo. Magickal workings happen because of the power of your mind not any external symbols/whatever else. These are used to enhance and focus your mind power. If you need to improve your health in a magickal way then you'd better do a Mars square (for physical strength) or a Sun/Jupiter square (for general health and wellbeing)
If it's the first one then I don't know, maybe another person can answer it.
