Sculptra in forehead and under eyes?

Sculptra is made of a substance called poly-L-lactic acid.  Plastic surgeons are very familiar with this substance because it is used to make a very popular absorbable suture trade named Vicryl.  These sutures are loved and hated by surgeons like myself.  They are strong, hold knots exceptionally well,and are absorbed by the body.  The problem is that they are absorbed by a profound inflammatory response.  This inflammatory response frequently causes sutures to "spit" through the skin or cause what we call a sterile abscess.  This is not stuff that you want anywhere in your body in excess of a small knot deep under the skin.  When Sculptra is injected into the face it triggers the same robust inflammation inducing the body to lay down scar tissue.  This scar tissue deposition is cleverly marketed as "creating your body's own natural collagen."  prolonged inflammation can cause granulomas, firm nodules and even fat atrophy  and create a more aged appearance.  In my practice I use hyaluronate based products in a unique application that I call "aesthetic facial balancing."  To create safe, natural appearing and LONG LASTING results that actually induce growth of healthy vascular tissue instead of scar tissue.  I recommend staying far away from poly-l-lactic acid injections.  I hope this helps!All the best,Rian A.

Sculptra is not designed to go in the forehead (although temples it seems to do well) or under the eyes (particularily in the tear trough).  Sculptra is a bioactivator meaning your body's response will trigger the collagen formation and the amount of volume.  When placed over thinner skinned areas including under the eyes and the forehead, the risk of nodule formation is higher.  

I would not recommend having Sculptra injected under the eyes, because it is possible to develop lumps in that area.  If there is an area of depression on the forehead, then I think Sculptra could be used there.  If you are trying to just correct horizontal lines on the forehead, then I think Botox works better for this issue.  I do not necessarily think that there is a fear of injecting Sculptra into the forehead.  I think it is more an issue of whether it would help or not.   

You are correct on all counts. Many physicians do not inject any filler into the forehead for the reasons you stated. Intravascular injection into any vessel can, in rare cases, cause scarring in the area around vessel, and the initial can take weeks to heal.

Thank you for your question. Sculptra will
replace collagen lost during the aging process that will last more than two
years. Sculptra can restore a more youthful, natural look. It is best to
consult with your doctor to be sure this is the proper filler for you.

Sculptra is not commonly used in the forehead but if you had a good result in the past then it can be done. I've used it in the upper chest, temple, and through the face with good results.
