Would I be able to remove this 4x2 tattoo on middle of arm? (photos)

Thank you for your question and photo. I am puzzled by your question because a 532 laser is a good wavelength for red ink. Due to the intensity of the color, I would start with a lower setting. This tattoo is too large to be excised because the skin cannot be stretched tightly enough to bring the edges together. You would need a ski graft. Hopefully you can find a provider willing to treat you. Good luck!

I would always recommend against excision of a tattoo regardless of location as the sheer volume of skin that needs to be removed generally results in an incredibly unsightly scar.
I do not see any reason why someone would not use a 532nm Nanosecond or Picosecond laser on the red area of your tattoo as this wavelength is highly effective at removing red ink and you do not appear to be at risk of hypopigmentation given your skin type. I would find a Board Certified and Fellowship Trained Dermatologist who performs tattoo removal to examine your tattoo and give you their opinions on removal options with laser.
Hope This Helps!
