Female - 34 years old Ive had this crease in my stomach through my bellybutton ever since I was a kid. I was overweight most of my life until I lost a ton of weight around the age of 24 (I walked a ton when living in NYC). Ive maintained that weight loss for 10 years. No matter how much I workout or lose weight, this stomach crease doesnt go away. I want my bellybutton to look less...horizontal. What procedure do I need to fix this?
