I have extra skin on lower abdomen I guess it's genetics I don't know I'm 18 and been having it. I'm not over weight or anything is their a way I can get rid of this extra skin with out surgery?

Genetic testing. You may need to see a genetic specialist or dermatologist as there are rare skin conditions , e.G "pxe", that cause loose skin. Were you ever heavier & then lost weight: that can cause loose skin, hrs www.Thepmc.Org.
