The aesthetic industry has shifted. While fillers and Ultherapy once dominated the conversation, the trend has evolved from “instant volume” to “natural regeneration.” Here is a breakdown of the collagen stimulator taking the world by storm.
What is PDLLA?
Juvelook’s core ingredient is PDLLA (Poly-D,L-lactic acid).
Traditional PLLA: Uses plate-like crystals, which can cause intense stimulation and higher risks of nodules.
PDLLA: Uses spherical microspheres with a smooth surface. This structure is gentler, minimizes nodule risk, requires no post-procedure massage, and results in more even collagen growth.
The “Bi-Phasic” Formula
Juvelook combines 85% PDLLA with 15% non-crosslinked hyaluronic acid (HA).
Phase 1 (0–2 weeks): HA provides instant hydration and smoothing.
Phase 2 (2–4 weeks): As HA is absorbed, PDLLA microspheres stimulate fibroblasts to begin collagen production.
Phase 3 (1–12 months): Collagen networks mature, with results peaking around the second month. The PDLLA eventually metabolizes into water and carbon dioxide.
Choosing the Right Type
Juvelook (50mg): Micronized particles; the only stimulator injectable into the dermis. Ideal for fine lines, pores, acne scars, tear troughs, and neck lines.
Lenisna (200mg): Larger particles; designed for volume and contouring. Ideal for sunken temples, hollow cheeks, and deep nasolabial folds.

Is it for you?
Ideal: Those with thin skin, fine lines, acne scarring, or those seeking natural results without the risk of “filler face” (overfilling).
Avoid: Active acne inflammation, lactic acid allergies, those seeking instant, permanent results, or if pregnant/breastfeeding.
Key Tips
Standard protocol: 3 sessions, spaced 4–6 weeks apart.
Recovery: No massage required. Avoid blood-thinning supplements (Aspirin, Fish Oil, Vit E) one week prior.
Travel: Safe to fly immediately. Avoid pressing on injection sites for 24 hours.
Compatibility: Can be combined with Rejuran (skin repair) for synergistic effects, though physician assessment is required.
