Use of Absorbable Polydioxanone Threads in Facial Rejuvenation

This study found that polidioxanona threads increased hair density and satisfaction in treating various types of alopecia, with no adverse events reported, though the small sample limits broader conclusions.

This study compared the effectiveness of different thread types in improving collagen profiles in UVB-exposed aging model rats, finding that PCL threads were more effective than PDO and PLLA in enhancing dermal collagen characteristics.

In this study, polydioxanone threads significantly reduced hair loss and promoted hair regrowth in patients with androgenetic alopecia who did not respond to minoxidil and finasteride.

This study observed that injecting minimally cross-linked hyaluronic acid with PDO smooth threads in female patients with dry, cracked lips led to significant improvements in lip texture, elasticity, and reduced fissure depth, effects that lasted up to nine months with additional booster injections.

This review discusses polydioxanone threads as a promising, minimally invasive treatment for androgenetic alopecia in both males and females, but notes that further research is needed to optimize protocols and outcomes.
