Armlift scars can be thick. I would have a scar specialist like myself co-manage your scar after surgery so that permanent scars are less likely to develop.
Scars typically need 6-12 months post-op to show optimal results. I suggest not tattooing over the scar until it has completely healed. Please consult with an experienced cosmetic dermatologist for a consultation regarding skin removal. Best, Dr. Emer
I recommend waiting at least 6 months and ideally one year before considering scar tattooing since scars can continue to improve over a year and you may realize you may not need to tattoo or need as much done. Tatooing will improve the scar appearance if color matched accurately however it will change the texture or structure of the scar. Skin removal timing after massive weight loss depends on several factors, the most important being that you are medically and nutritionally able to undergo major surgery safely. You should also be able to show that you have reached or are near a steady goal weight to optimize your results. Dramatic changes in weight after having surgery will effect your results. Hope this helps!!
