Overview
Etrebelle is a poly-D,L-lactic acid (PDLLA) collagen-stimulating injectable from Korean manufacturer Yooyoung Pharmaceutical, offered in 50 mg and 200 mg presentations. PDLLA microparticles act as a scaffold for gradual neocollagenesis, and certain presentations combine PDLLA with hyaluronic acid to add an immediate component. It is intended for professional use in dermal-to-subcutaneous collagen restoration.
How it works
Once injected, Etrebelle's PDLLA microparticles act as a scaffold that stimulates fibroblasts to produce new collagen fibres over weeks to months. The PDLLA is naturally degraded by the body over time, leaving behind newly formed collagen for sustained results; where hyaluronic acid is co-formulated it contributes an early plumping effect.

Composition
Poly-D,L-lactic acid (PDLLA) microparticles supplied as lyophilised powder for reconstitution. Available in 50 mg and 200 mg presentations; the 200 mg presentation is reported by distributors to combine approximately 170 mg of poly-lactic acid with approximately 30 mg hyaluronic acid.
Usage & handling
Reconstitute the lyophilised vial (distributors report reconstitution to roughly 5 mL sterile water) and allow hydration per protocol. Inject into the deep dermis to subcutaneous layer for professional use only. Collagen-driven results build over weeks to months; space repeat sessions per clinical response.
