I have bags under eyes when I smile. Which would you recommend; fat grafting or fillers? (photos)

This is a great question andthank you for the attached photos! Based only on what you mentioned and thephotos that you have attached, I see your eyes and smile appear well and normalfor your age. You need to keep in mind that there are some individuals whoexperience puffiness under the eyes when smiling. This is because theirorbicularis muscle is stronger compared to others, hence, it puffs a littleunder the eyes. This is not really because of fat prolapse.
However, if you probably see somethingthat I have not in your photos, I would highly recommend consulting a boardcertified plastic surgeon in person so that he or she can give a proper look atyour eye bags as well as the fine lines that you have mentioned. From there,your surgeon will be able to give you options and develop a plan that will suityou and your needs well. Your surgeon may offer you surgical and non-surgicaloptions or sometimes both. For surgical treatment, your surgeon may offerblepharoplasty. This procedure will remove or reposition the fat, should therebe fats in there, to eradicate under eye bags. A milder approach that providestemporary results would be through filler injections. Fillers can help concealthe under eye bags so that your face would look youthful. The results of fillerlook natural and such treatment offer little to no after effects. Nevertheless,since the result is temporary, you may need to repeat the procedure annually orevery two years to maintain the result. All the best!

I never like to consult based on photos but what your photos seem to show is very common.  Some people, when they smile, have a very strong orbicularis muscle the "bunches up" a bit under the eye.  It's not a fat pocket, although sometime it can be related to losing volume around the eyes as we age.  Firstly, there is nothing "wrong" with your smile and it doesn't age you, from what I can tell in the photos, but if it bothers you, seek out a consultation with a board certified oculoplastic surgeon and injection specialist.  This is usually treated very effectively and without significantly changing your smile with a few units of botox injected just under the skin over the overactive muscle.  While the treatment is not "permanent", you don't want permanent treatments on your face (trust me) because your face changes slightly every few months as you age and what looks good now, may not look good 5 years from now.   That said, this "off label" use of botox or one of the other neuromodulators has a long term effect because after a series of treatments (usually patients come in 3 times per year) the muscle in the area becomes weaker and atrophies and in my experience, patients need less and less treatment (or none at all as they age).  It is not a risk free treatment though because if too much botox is injected in this area, the eyelid can droop or retract down, and that is not an attractive look.  So it's essential to be treated by someone who has experience with these types of treatments.  DO NOT , in my opinion, have surgery to remove the muscle or thin it out.  It almost never looks natural and often causes all types of problems years down the line.I hope that helps and best of luck!
