I'm 22 and have saggy, wrinkly skin with stretch marks all over my lower stomach. Is a tummy tuck my only option?

Hi, you have several options to treat abdominal skin.  A tummy tuck is typically the best option when there is loose skin.  It is recommended to perform this type of surgery after you are finished having children to prevent recurrence with pregnancy.  It is always best to have this question answered after an office consultation with a board certified plastic surgeon. Good luck.Dr. E Wright

You probably need some sort of skin removal to be happy, but this really depends upon your expectations and your plans to birth additional children.  The amount of skin removal in TT depends upon the surgeon's technique and the patient's tissue characteristics.  A great deal of skin above the belly button may be removed in some patients with a lower belly button or a great deal of skin laxity.
BodyTite is a non-excisional device that utilizes radio-frequency assisted lipolysis (RFAL) to address the shortcomings often associated with traditional liposuction or surgical body and face lifts, including sagging or wrinkly skin and scarring, by inserting a wand under the skin to coagulate inside while tightening the skin on top. BodyTite does not remove any fat, but it is capable of producing a 45% contraction in tissues. 
Schedule an in-office consultation with a board certified PS who performs BodyTite and obtain his/her opinion.  If BodyTite is not the best option; a small scar TT could be considered.
