I am a 30 yo woman. I have fillers in my cheeks and don't want any more fullness there. I do want fullness in my hollow cheeks tho (don't like the Buccal fat remove surgery look ) The reason i wanna do sculptra is only for building collagen which i read u can do for 2 years. But since i already look 5-10 years younger than my age, i don't feel like i need 2-3 treatments. Is 1 treatment enough for building collagen for 2 years ? Or is it just waste of money?
