Three skin boosters, three different collagen pathways. Belluxi (PCL), Juvelook (PDLLA), and Ejal40 (HA) all claim to stimulate collagen — but through completely different mechanisms. Here's the science.

Frequently Asked Questions
What is the difference between PCL, PDLLA, and HA skin boosters?
PCL (Belluxi) uses microsphere scaffolds that attract fibroblasts over 3-6 months. PDLLA (Juvelook) triggers an inflammatory cascade that recruits fibroblasts within 4-8 weeks. HA (Ejal40) provides immediate hydration while amino acids signal fibroblasts to produce collagen. All three stimulate collagen but through different biological pathways.
Which skin booster lasts the longest?
Juvelook (PDLLA) typically provides the longest results at 12-24 months. Belluxi (PCL) lasts 12-18 months. Ejal40 (HA) lasts 6-9 months but provides the fastest visible improvement.
Can I combine different skin boosters?
Yes — many patients benefit from a layered protocol. Ejal40 provides a hydration foundation, Juvelook improves texture, and Belluxi adds volume. Your doctor will design a sequenced protocol based on your skin condition.
Which skin booster is best for aging skin?
For mature skin (40s-60s) with significant volume loss, Belluxi (PCL) creates the densest collagen matrix. For fine lines and texture (30s-50s), Juvelook (PDLLA) excels. For early aging with dehydration (25s-40s), Ejal40 (HA) is often the best starting point.
How many sessions do I need for skin boosters?
Typically 2-3 sessions for Belluxi and Juvelook, or 3-4 sessions for Ejal40, spaced 2-4 weeks apart. Results build progressively with each session.
Are skin boosters safe?
All three products have established safety profiles. PCL, PDLLA, and HA are biocompatible and fully biodegradable. Side effects are typically limited to mild swelling for 1-3 days. Consult your doctor for personalized advice.
