What is PDLLA

Juvelook & Lenisna

The ideal solutions for the loss of collagen

Collagen is the source of skin elasticity, but it will start to lose at the age of 18. The loss speed will accelerate after the age of 25, and it will lose 1% every year after the age of 40.

The loss of collagen will cause the loss of skin firmness, skin dryness, sudden redness, fine lines, and wrinkles.

What is PDLLA

Poly-D, L-Lactic Acid(PDLLA) is an isomer of Poly Lactic Acid(PLA) in which the D-form and L-form of lactic acids are bonded in random order, maximizing the contact surface area involved in collagen production.

PDLLA is a polymer extracted from 100% pure nature and has been approved by FDA that can be used in the human body.

Thanks to its biocompatibility and biodegradability, PDLLA is widely used in the medical field to fabricate resorbable medical devices and is also used for drug delivery.

Particle structure

Outer structure- Spherical and foamy shape

  • Minimize the damage on surrounding tissue

Inner structure- Patented reticular and porous structure

  • Better biocompatibility and biodegradability
  • Slow decomposition from the inside prevents drastic acidity change around the particles
