Yag laser or Cutera Enlighten on possibly scar prone skin?

When you mention Yag laser in your question, I assume that you are referring to Q switched laser.  The enlighten laser is also a 1064 Yag laser (as one of its 2 available laser wavelengths.)  However, an advantage to the enlighten is that it is a picosecond laser.  Data shows that enlighten should provide you with more complete results in approximately 40% fewer treatments than with Q-switched lasers. This should be particularly true if your tattoo is dark ink, as is suggested by your description of it being an "outline."  There should not be a higher incidence of scarring with one vs. the other.  While scarring can occur with any laser treatment, if the treatment is performed properly, the risk of scarring should be very low.   

Thank you for your question! Both lasers would work on black ink, especially with an outline tattoo. With Cutera Enlighten you would probably have it done faster, in fewer treatments, while Yag might take extra treatments. When it comes to your scars, I would make an appointment and have an evaluation with an expert before proceeding with the laser tattoo removal. There is always a chance of scarring and hypopigmentation. Best of luck!
