The collagen-stimulating method induces your own tissue to create volume on its own, so results tend to appear gradually and feel natural. It is characterized by filling that blends with the original tissue rather than abruptly increasing volume.
Collagen-stimulating types such as Sculptra (PLLA) or JUVELOOK Volume work by stimulating fibroblasts to increase self-collagen rather than filling with foreign material. Changes progress gradually over weeks to months, so they are known to give a natural sense of restoration without a 'suddenly changed' impression. For Sculptra, collagen neogenesis is reported to appear over approximately 6-12 weeks, and the effect is reported to last up to about 24 months.
However, because immediate changes are small, it may feel slow, so it is advisable to understand the trade-off between naturalness and time when making your choice.
