How Can I Get Rid of a Lower Eyelid 'Bag' when I Smile? (photo)

You are young, and you don’t appear to have fat pockets that are bulging.  Rather, hypertrophy of the muscle can cause this effect, which looks very normal in many people.  If you aspire to reduce that, you can try botox under the eye as it may soften the bulge.  You may not like the result, though the effect will wear off in 3-4 months.  If you like what you see after treatment with botox, you can continue.  Many injectors won’t perform that type of botox treatment, so be sure to choose someone with a lot of experience.  Good luck!

  That bag that you see is really no bag at all.  It really is due to the orbicularis muscle which is a vital part of the lower eyelid anatomy.  We need to remember that we are all made somewhat differently.  For you, you see this "bag" which may be more prominent on you than on others your age.  But there is no pathology here and nor is it something which should bother you cosmetically.  It looks fine to me.

That is the orbicularis oculi muscle that is critically necessary for holding the lower eyelid up against the eye.  Take away that muscle and the eyelid will not stay up against the eye.  If that sounds horrible, it should.  Please be careful out there.
