童颜针的主要成分为聚左旋乳酸，是一种人体内的天然物质，注射后可刺激皮肤深层胶原蛋白生长，使皮肤逐渐自然饱满，注射后3-6个月自体骨胶原会慢慢开始生长，是维持自然年轻态的最佳选择，也有“天后针”的美誉，长出的胶原蛋白可维持3-5年。
The main ingredient in Sculptra is poly-L-lactic acid, a natural substance present in
the human body. After injection, it stimulates the growth of deep skin collagen,
gradually restoring the skin's natural fullness. Within 3-6 months after injection, the body's own collagen production will gradually start, making it the optimal choice for maintaining a naturally youthful appearance. The collagen produced can last for 3-5 years.
