Can dermal fillers be injected into the perpebmalar groove?

These are fussy services.  This is the first and best line treatment for most individuals.  The critical issue is finding an injector who actually knows what they are doing.  If you see someone who is uncomfortable with the treatment, to not insist that they do it.  Keep looking.  Yes there are surgical options but they are much more invasive and associated with complications. Chemical peels are another option for some.

Thank you for sharing your question.  Fillers like Restylane and Belotero are commonly used in the tear trough to improve the transition from the eyelids to the cheeks.  Sometimes, surgery with blepharoplasty and fat repositioning may be a better option.  Consider a consultation with an oculoplastic surgeon to discuss which treatment may be best for you.  Good luck!

Hello,
Thanks for your question.

I think you mean Palpebromalar Groove. Combination therapy may be needed although the results are variable and complete removal not always successful. 
Reducing the width with cheek volume and direct injection can assist, plus using a skin lightening modality is recommended depending on age. 
Please note, medical advice is given as general advice only and is not a substitute for a full consultation and examination.
