Is Devolux® PLLA Better Than Sotorior® Botulinum Toxin?
Devolux PLLA and Sotorior Botulinum Toxin, which is better? However, this is a classic case of comparing apples to oranges. The truth is, Devolux and Sotorior are fundamentally different products designed to address entirely different concerns. Devolux® plla filler stimulates gradual collagen regeneration to restore volume and improve skin structure, while Sotorior® delivers targeted neuromuscular modulation to smooth dynamic wrinkles. One is not inherently 'better' than the other; the right choice depends entirely on your individual aesthetic goals."
About Devolux® PLLA
Devolux® PLLA is a biostimulatory injectable designed to induce collagen regeneration gradually, improving facial and body volume, skin firmness, and texture.
How Devolux® PLLA Work
Devolux® contains poly-L-lactic acid microspheres suspended in a sterile carrier. When injected into subcutaneous tissue, it triggers a controlled inflammatory response that stimulates fibroblasts to produce new collagen over weeks to months. This gradual volumization provides natural-looking improvements in skin texture, facial contour, and body areas requiring volume restoration. Multiple sessions are often required to achieve optimal results, with longevity often exceeding 18–24 months depending on the treatment area and patient metabolism.
Primary Indications
Mid-face volume loss and sunken cheeks
Facial lipoatrophy correction
Skin texture improvement and collagen stimulation
Buttock or body contour enhancement
Onset, Duration, and Treatment Schedule: Gradual results appear over 4–12 weeks post-injection. Multiple sessions (2–4) are recommended depending on the area. Longevity ranges from 18–24 months.
Naturally Long-Lasting Effects
Clinical studies indicate significant improvement in facial volume, nasolabial fold depth reduction, and skin texture enhancement. Patients typically experience progressive improvement over several weeks, resulting in natural, long-lasting results without the immediate volumetric “fill” effect of hyaluronic acid.
About Sotorior® Botulinum Toxin
Sotorior® Botulinum Toxin is a high-purity neuromodulator that temporarily inhibits targeted muscle contractions, effectively reducing dynamic lines and wrinkles.
How Sotorior® Botulinum Toxin Work
Sotorior® works by selectively blocking acetylcholine release at neuromuscular junctions, temporarily inhibiting muscle contraction. This mechanism relaxes targeted muscles, reducing dynamic lines such as crow’s feet, glabellar frown lines, and forehead wrinkles. The onset of effect is typically 3–7 days, with peak results at 2 weeks and a duration of 3–6 months. Sotorior® can also be used for masseter reduction, hyperhidrosis, and other therapeutic aesthetic indications.
Primary Indications
Dynamic facial wrinkles (forehead, glabella, crow’s feet)
Masseter hypertrophy reduction for facial slimming
Hyperhidrosis management
Neck lines
Onset, Duration, and Treatment Schedule: Effects appear within 3–7 days, peaking at 14 days. Maintenance injections are recommended every 3–6 months.
Visible Wrinkle Reduction
Randomized controlled trials demonstrate consistent reduction in dynamic wrinkle severity scores. The predictability of dose-response and onset allows precise tailoring for each patient. Repeat treatments maintain results and minimize muscle overactivity over time.

Practical Decision Aid
Primary complaint: Volume loss → Devolux®; Dynamic wrinkles → Sotorior®
Tissue quality: Thinner skin with laxity → Devolux®; strong muscle contraction lines → Sotorior®
Treatment goal: Collagen induction → Devolux®; immediate wrinkle smoothing → Sotorior®
Contraindications: Check for autoimmune conditions, pregnancy, or neuromuscular disorders
First-line choice: Align product with primary concern; combination therapy if multiple concerns exist
Case Examples
Case 1: Nasolabial folds and fine facial lines in a 45-year-old patient improved with two Devolux® PLLA sessions over 8 weeks.
Case 2: Crow’s feet in a 43-year-old patient treated with Sotorior® injections, achieving full wrinkle reduction by 2 weeks.
Devolux® PLLA and Sotorior® Botulinum Toxin are not directly interchangeable. Each has a distinct mechanism, ideal indication, and treatment schedule. Clinicians should match the treatment to patient-specific goals, combining both where appropriate for comprehensive aesthetic outcomes.
