Sculptra for Malar Grooves at 18?

So I'm a 18 years old, 5'7, 120 lbs female with malar grooves. I've had them for a long time since my mid face seems to be very flat. I started taking collagen 10 weeks ago and the line has improved but not gone away because of the volume lost. I want to try sculptra in the mid cheek to see if it would help but I want to know if there is any other suggestions. I also have hyperpigmentation under the eye which make them look more pronounced, but they still appear even with makeup.
