Ive read a little about it, and from what I can gather, it may actually work to fade them a little, so depending on your skin tone, the actual tattoo itself, plus the amount of tanning/fake tan you put on for your competition, it might give you some good results.
The laser is the only real way to go, I mean, all that I said might end up giving you about 50% reduction in a perfect situation, if you have light skin tone, good acid burn off/fading of 20% after multiple applications, and really dark fake tan, but is that going to be enough? I cant say for sure, let us know since youre already ordering some. If you did actual before and after photos, that would be awesome.
