15 days post op, I have scars on the sides of my eyes after upper blepharoplasty. What I can do? (photos)

In retrospect, I probably would have removed the tattoo with a laser.  Darker colors are relatively straightforward to remove.  That said, at this point I would use scar gel (I like Biocorneum, although be careful not to get anything in your eye), and wait.  If more tattoo needs to be removed, try to find a doctor who performs laser tattoo removal.Best of luck!

Generally, laser of the appropriate wavelength, energy and pulse duration is the most appropriate method of addressing unwanted tattoo.  Dermatologists usually have the biggest collection of these types of lasers.  You're skin is unusually inflamed for two weeks out.  From the picture it looks like you still have sutures in your skin.  If this were in fact true, I would recommend having your surgeon remove the sutures immediately.  Time is very helpful for healing eyelids.  Things that early on look like they will never heal can do remarkably well.  I think you are feeling insecure about your surgeon's decision to directly excise the eyelid tattoo.  I think your concern is appropriate and time will tell if this was a good choice or a mistake.   

You are very early in the healing period.  With time these scars will start to look much better.  It will be difficult to actually excise the wide eyeliner.  To do this would require an incision below the lid crease, so it would be visible.  You may want to try putting a lighter colored tattoo over the black ink to see if you can lighten the color and mask how thick it is.
