If you have lines and light colors, find a tattoo shop with a laser. Femtosecond in hospitals is not necessarily easy to use, with low power and poor effect. If you go there many times, you are likely to leave a scar.

So if your tattoo is heavy or has other colors, such as red. I suggest you give up. You might as well choose a favorite pattern to cover it.

Tattoos that can't be washed clean are all lines and stripes, and there is no fog.

As far as I know, even the lines can't be restored to the previous skin. Look carefully after washing, and you will still see a faint outline.

The laser just breaks up the pigment and then slowly metabolizes it.

It can be said that the first three times have the best effect, because the pigment color is heavy.

The laser must hit the deep pigment to get feedback, which has no effect on meat at all. I don't know if you know what I mean.

Let's just say.

Lasers are like the sun, and tattoos are like clothes. The darker the color, the better the effect. For example, color tattoos, many tattoo artists will say that they can't be washed off because they can't find the right laser frequency, while light-colored and white tattoos are directly sentenced to death because the laser doesn't give feedback at all.

So when you wash it more than three times, the tattoo begins to fade, and the effect will get worse and worse. Finally, because the color of the pattern is too light, it can't cause laser reaction.

So don't try to go back to the past. It is best not to pay attention to what you can't see.

Most of them will become dirty patterns with different shades, and some will proliferate and leave scars. Finally, they can only choose a suitable tattoo pattern to cover up the defects.

So I said that tattooing is a waste of money and feelings, and the final result is just self-defeating.
