Is 20 too young for liposuction

I have stubborn fat pockets on my belly despite being a healthy weight and exercising and lifting regularly for over a year. My BMI is 19 and I have less fat overall but the fat that is there seems to be in my midsection.

(Please don’t say “just work out” bc I am tryinggg as mentioned but the fat just won’t budge lol)

But is 20 too young as a woman? Should I wait?
