Loose skin below brows creates folds Would Sculptra help the skin tighten under eyebrows and lift my eyebrows? (photo)

I would not recommend using Sculptra around the eye, including under the brows.  The skin is thin around the eye and it is possible to get visible bumps from Sculptra in that area.  If you were going to use any filler in the eye area, I would recommend using one of the hyaluronic acid fillers.  

Sculptra is contraindicated in this area because of the likelihood of nodules.  Since your brows appear to be at a normal position, the best results for this problem would be attainable by blepharoplasty. if you do not wish to have surgery, alternatives could include daily retinol cream and Aluma or other radiofrequency treatments to tighten the skin, Botox to the glabellar complex including the depressor supercilli and also to the peripheral fibers of the periorbital sling to give a gentle lift to the brows across the entire brow, and/or Beletero or another hyaluronic acid filler just under and perhaps above the brows to lift the brows.so 

Sculptra is
not recommended for this area as treatment would be too superficial and cause
nodules.

If you were
interested in tightening the skin I would recommend Thermage Eyes. Thermage
Eyes utilizes a tip specific for the eye area; it uses focused radiofrequency
energy to stimulate the body’s own natural renewal process. A

Thermage treatment can help improve the appaerance of sagging or
loose skin giving you a smoother, younger look with just one treatment and no
down time on the face, neck, eyes and body. Most patients see some immediate
improvement, and continued improvement for up to 6 months as their skin regenerates new collagen. This
treatment will also help lift the eyebrows; alternatively you could try Botox
to bring up the eyebrows as well.

It is important to consult with a Board Certified Dermatologist to
see what treatment is best for you.
