A You are a perfect candidate for Sculptra to the temples and upper face, and while you're at it I'd recommend also treating your lower face to preserve the excellent condition of your skin. Around 30 years of age, we begin to lose collagen; Sculptra prevents and restores that loss by stimulating your body's own collagen production for 6 months after it's placed. Then at that point studies show you hold onto that newly produced collagen for TWO years!
Filler is amazing, but most likely you need more syringes to reach the correction that you desire. Then once you reach that aesthetic goal, unfortunately the filler dissolves usually by 12 months for the upper face. This is not the case with Sculptra. You can expect to maintain the correction from Sculptra for two years at least, possibly longer.
So, financially, I believe Sculptra to be the better choice as well. You'll need at minimum 4 vials of Sculptra, which can cost near $2400 and up, but remember will last 2 years. Whereas you likely need at least 4 syringes of filler yearly (so 8 syringes for 2 years of results) to reach similar revolumization goals, which can cost near $5600 (at $700 per syringe). So comparing $2400 to $5600 for two years of results, not to mention also gaining higher quality skin texture, the choice should be clear.
If you have a high metabolism or exercise a lot (hello marathon runners and body builders), then Sculptra is absolutely the best choice for you. Filler dissolves more quickly in this type of person, whereas the collagen you build from Sculptra won't melt away due to your level of activity.
A major contraindication for Sculptra is keloid or hypertrophic scarring, so if that's the case unfortunately it's not the product for you.
