At age 23, what can I do for my sunken/wrinkled eyes & under eye circles? Should I see a dermatologist? (photo)

Your eyes are gorgeous. As are your smile lines. For now, invest in a good, creamy, light reflecting concealer for your dark circles and call it a day. Down the road, you may want to consider a bit of HA filler in your tear trough, but not necessary now.

Thank you for sharing the question and photos. Many young patients complain if the same problems. The bags can be improved by injecting hyaluronic acid filler in the area beneath the lower eyelids. This might also help with the darkness. The best method for removing those wrinkles which bother you, especially when smiling is Botox injections. This should have a great impact on your eyelids. Make an appointment for consultation with an Oculoplastic Surgeon for comprehensive evaluation and discussion of treatment options. Good luck.

You do have a bit of a circle.  Restylane under eye filler is very helpful for this.  You need an expert injector to get the best possible result.  Treatment will last well over a year.

You have some hollowing under the eyes which may be causing the skin to look dull and give you dark circles.  Try some HA filler first such as Restylane or Belotero.  These should help the appearance of the lower lids, and also the wrinkles.  A small amount of Botox/Dysport will also help with the smile lines. 

While I cannot see your entire midface region, your lower lid region does look very deep and pigmented(dark) for someone of your age. In addition your lower lids demonstrate significant lateral bowing(scleral show) for someone of your age which indicates congenital poor bone support. The wrinkles with animation(smiling) is due to lack of underlying support.Facial fat grafting will resupport the area, including the scleral show, dark hollows and the vascular growth factors with slow the aging of this region moving forward.Fat cell survival, and aesthetics are highly technique dependent and very successful in the right handsHope this helps

Lower Eyelid Bags can be caused by many different issues. Sometimes a combination of issues are contributing to the dark, heavy look of the lower lids. Changes in skin, fluid accumulation, muscle, fat from the eye socket, and changes in the cheek and surrounding structures can all contribute. It is important to have an experienced physician evaluate your eyelids to determine all the changes that need to be addressed to achieve your goals. In many cases, in office procedures can be used to improved the shadowing and baggy appearance of the lid. I commonly use injections such as Restylane, and Voluma in combination with skin rejuvenation to improve the lower eyelids without surgery.

Botox can be injected into your crow's feet to relax the dynamic contraction of your orbicularis muscle when you smile or move your face.  Many people have this wrinkling around the eyes and it can be somewhat genetically inherited.  Filler injections to your tear trough (juvederm or belotero) can be good options to soften the appearance of the darker circles.  There are many different options and only an in office consultation can help to determine which is best for you.  Your best option would be meet with a board certified oculoplastic surgeon to review your case.  There are several in Boston.  Good luck!
