Under Eye Bags and Stretched Skin?

Almost impossible to answer with out photos and/or an exam. Although you can camouflage the problem in certain cases with fillers, a blepharoplasty is generally recommended.
Patients who would benefit from a blepharoplasty include those who experience:
• Excessive, sagging, or wrinkled upper or lower eyelid skin.
• Excess upper eyelid skin that interferes with vision.
• Loss of your natural upper eyelid crease
• If you have puffy pouches of fat in the upper or lower lids that create a tired or aged appearance.
• Orbital Rim Show: visibility of the bone under the eye sometimes contributing to a dark ring or shadowing.
Normally, everyone has a small amount of fat around the eyes. If the quantity of fat increases or the local tissues stretch and weaken, the fat begins to bulge producing “bags.” Occasionally this bulging is seen in young patients and is an inherited family trait, and not a result of aging. These changes have a profound effect on one’s appearance giving a tired or haggard appearance. An attractive face with these early signs of aging can affect a patient’s self-image, attitude and sense of well-being.

    Eye bags getting worse in a short period of time can be due to a number of endocrine problems or fluid balance problems.  What is the medication or medications you have been taking?  If caused by a medical problem, treatment may reduce the swelling.

Water retention in the lower lids can come from a variety of sources, such as allergies, salt and alcohol intake.  There are several medical conditions that will cause fluid retention as well and you should rule these out first with your physician.  Your skin should tighten up again.
