How do surgeons assess the severity of loose skin to determine what procedure would be best for a patient? For example, if a patient wanted to treat loose skin on their thighs, how would you determine if a thigh lift was needed or if a less invasive skin tightening treatment (e.g. bodytite, skintyte, etc.) would effectively treat the issue? Does the best treatment differ at all depending on the cause of loose skin (weight loss vs aging)?
