Well...clinics use a pulsed Nd:YAG laser, sometimes frequency doubled though I wouldn't know the benefits. It feels like a large rubberband is being popped against your skin, I've heard. You could probably do it at home with a watt of 445 but I'm trusting that you and anyone reading this are smart enough to realize how terrible of an idea this is.
From videos I have seen of laser tattoo removal it looks like they use a extremely powerful pulsing laser of some unknown wavelength that instantly turns a ~1mm diameter circle of skin into scar tissue.
Have fun op:
well i need it gone before tomorrow, so if i can't get it removed via laser or whatever I'm gonna use either a really sharp knife or a razor blade, dealing with a patch of skin gone is less painful than having to see this tattoo
I'd go with the knife then...because someone burned an X into his arm with a 445 and LSRFAQ said that he had to worry about possible cell mutation or something from such prolonged exposure to 445nm laser radiation. Knife or a piece of metal heated over a fire to kind of melt it off maybe...
Kind of one of the reasons they say not to get a tattoo unless your happy with taking it to the grave. One of the many reasons I don't have any.. I can't think of any designs that I wouldn't end up regretting at some point.. Plus i'm allergic to pain.
445nm is totally not the way to do it. Trick with tattoo removal is to hit the tattoo color, and not the skin. Red is used, and near infrared. 445nm will burn just your skin. This also means red tattoos are almost impossible to remove.
I guess there are tons of other problems too. It's simply not something you can do at home.
Definitely a bad idea, if not done professionally ..... you need a high power short pulsed unit (ND:YAG or also ER:YAG cavities) for do "ablation" of the skin part with the tattoo ..... and it still can left scorch, if not done in the right way, also professionally.
Also, it usually need more than one pass, with intervals so the skin can "heal" the ablation, before do the next one ..... doing it at home, you risk to end just with a very bad scorch for burning (ustion) thar follow and mark the tattoo also more deep, and that probably may need aesthetical surgery for be healed (even if possible to heal it, with skin transplants) ..... don't try it, don't even think about it at home !!
if i were you i would just save some cash to get a other tattoo to overlap the old one you want gone ( and also tell her the truth? , if im understanding this situation correctly ).
But i dont see that happen before the 14th
lasering it yourself is a terrible idea, but i gues you understand that from the previous posts of others
and like mentioned before lasering a tattoo of takes multiple sessions, it wont just dissapear in one day
