3.5 months after abdominal etching and midsection lipo and I have weird spots/stains on my side. Will they go away? (photos)

I recommend getting a formal evaluation with a cosmetic dermatologist. Hyperpigmentation can be improved with a combination of lasers, Aerolase, microneedling/prp, skin lightening, peels, and skin care. Sun protection is essential. See an expert. Best, Dr. Emer

Dear barbie272,liposuction can cause bruising which can last for months. If you have any concerns, I would suggest you to consult your plastic surgeon. Only after a thorough examination you will get more information and recommendations.Daniel Barrett, MD, MHA, MS

Hello, Thanks for sharing your query. The post liposuction pigmentation are common and normal process of resolution of bruises. Sometimes there may be Dermal hemosidrin deposits. These take between 6mo to a year to resolve. If any residual pigmentation present you can undergo laser. Followup with your surgeon.
