300% Increase in Collagen and 50% Young Collagen !!
They never really stopped working.
What happened is one overhyped version gave the entire category a bad name.
In this video, I break down why new smooth and twist face threads may be far better than most people think, how they can support glow, structure, collagen, and even subtle lift, and why right now they may be one of the biggest value plays in aesthetics.
I also show you the study that changed the conversation for many people: molecular data demonstrating increased TGF-β signaling, increased type III collagen, and visible wrinkle reduction after thread placement. We’ll cover the difference between PDO, PCL, and PLLA, why barbed cog threads became the “bad leaf” that made people dismiss the entire branch, and why safer, simpler monofilament threads still deserve attention.
If you want a treatment with long surgical safety history, no vascular occlusion risk like filler, no permanent foreign material, and real biologic stimulation under the skin, this is worth a serious look. I also share where I think threads work best, who may benefit most, and what at-home add-ons like red light can do to help support results.

Cho SW, Kim JH, Choi SY, et al. Efficacy study of the new polycaprolactone thread compared with other commercialized threads in a mouse model. Journal of Cosmetic Dermatology. 2021;20(6):1940-1947. doi:10.1111/jocd.13883. PMID: 33421303. This is the key mechanistic paper showing increased TGF-β, increased type III collagen, and reduced wrinkle area, with the newer PCL thread outperforming comparison groups in that mouse model.
Ha YI, Kim BJ, Jeong KH, et al. Histological and molecular biological analysis on the reaction of polydioxanone and polycaprolactone in rat model. Journal of Cosmetic Dermatology. 2022;21(4):1490-1499. doi:10.1111/jocd.14587. PMID information is indexed via PubMed record 34847267. This paper supports the fibroblast/TGF-β/collagen signaling story and compares tissue responses of PDO and PCL over time in an animal model.
Lots TCC, de Oliveira TM, de Souza LKB, et al. Effect of PDO Facelift Threads on Facial Skin Tissues: An Ultrasonographic Analysis. Journal of Cosmetic Dermatology. 2023. PMID: 37128828. This is useful because it is a human follow-up study showing ultrasound evidence consistent with collagen formation around PDO threads and improvement in facial tissue appearance over 120 days.

Journal of Cosmetic Dermatology. 2019;18(1):84-93. doi:10.1111/jocd.12745. PMID: 30105878. This is a larger clinical outcomes paper reporting high patient and surgeon satisfaction with minor complications over follow-up.
