What procedure would tighten the skin on the temples? And would this elongate and slant a persons eyes more?

There are a number of different techniques to address this area however without pictures it is difficult to assess your goals. I would recommend that you schedule a consultation with a plastic surgeon to discuss your options. 

It
would be difficult to determine this without seeing you for a consultation.Without seeing what areas you are talking
about, it is hard to know what technique would be best to treat the area.You should discuss your concerns with your Plastic
Surgeon.

Hello.  Thank you for your question.  It is impossible to really assess your concerns without pictures.  However, there are several ways to tighten skin in the temple region without slanting or changing the eyes.  A lateral/temporal brow lift is very useful for elevating the brow and tightening the skin in the temple region.  Augmentation of the temple region with fat or fillers can tighten the skin.  Laser skin resurfacing can also be helpful for mild wrinkling and skin laxity in the temple region.  I would encourage you to seek a consultation with a board certified surgeon with experience and expertise in facial rejuvenation and allow them to fully assess your individual case and determine the best treatment plan to achieve your goals.  I hope this information is helpful.
