Why is'nt PicoSure laser working?
Hello, thank you for your question and for including a photo. The 1064 wave length is very effective on black, the PicoSure has 755 & 532 wavelengths. There are several devices in the market that have the 1064 wave length. You should check in your area to see if that is available. Good Luck!
Spread out your treatments
Thank you for your question and photographs. How fast tattoo goes away depends on a lot of things. Wrists are always slow; similar to hands feet and ankles. If your tattoo was not very old when you started treatments, it is going to take longer. If you want the fewest number of treatments, spread them out longer. The more time your immune system has to work on your tattoo, the more goes away with each treatment. You could also try some Nd:YAG 1064nm treatments which I assume your surgeon has. Good luck.
Picosure hasn't cleared black tattoo after 10 sessions
I think that black is better treated with the 1064 wavelength. There are pico lasers and nano lasers with this wavelength that you should try. I think the Picosure is coming out with a 1064 too. Other things which can be done are CO2 laser or microneedling with the treatment and this seems to help.
Often it can be helpful to switch to a laser which uses a different wavelength of light. Picosure uses 755 nm. I would consider trying YAG laser at 1064 nm, either Q-switched YAG or a picosecond YAG. Best of luck.Dr. Ort
