i have tattoos and am very pail, if i cover my tattoos with heavy material and or zinc when i use the tanning bed will the melotan still darken the skin that doesnt get the uv exposure.

ive heard the compound is easier on ink pigmentation yet some of teh body builders i see who have sleeves that were donee in the last 4 years, already looks so faded. so is that from over tanning in the bed?
