Thank you for your question. Methods such as prp, mesotherapy will not be helpful in the improvement of the existing deformity. therefore, I think the most useful method in the treatment of your current contour deformity is surgical scar revision.
First of all thanks for your question. Tattoo removal requires multiple sessions and progresses slowly. You have a satisfactory result for the first session, but I think the rash should not last that long. Keep that in mind that especially green and red tattoos are more resistant to laser treatments than black and will take longer to erase.
Thank you for the question. This line is called tear trough deformity and it can be treated with both HA filler injections and fat transfer. If this is your only complaint, it may be a better idea to treat it with HA fillers. HA filler treatments are easier (for the patient) and faster. Fat transfer procedures are more like a surgical procedure but it's safer. However, if you have other complaints such as loss of volume in the cheekbone area or temple, you can get a more effective result with fat injection.
