How Botox and Fillers Work
Botox and dermal fillers represent two distinct categories of injectable treatments used in aesthetic medicine. Though often mentioned together, they operate through completely different mechanisms and target separate aging concerns. Understanding the difference is essential before considering either procedure.
Botulinum toxin, marketed as Botox, Xeomin, or Dysport, temporarily blocks acetylcholine release at neuromuscular junctions. This relaxes the targeted muscle, reducing dynamic wrinkles that form from repeated facial expressions. The effect sets in within 3-7 days and reaches full strength at approximately 14 days post-injection.
Dermal Fillers: Restoring Volume
Dermal fillers work by physically adding volume beneath the skin surface. Hyaluronic acid fillers such as Juvederm and Belotero integrate with existing tissue to plump nasolabial folds, lips, and cheeks. Calcium hydroxylapatite products like Radiesse provide structural scaffolding for deeper folds and jawline definition. Poly-L-lactic acid (Sculptra) stimulates collagen production over 4-6 weeks rather than providing immediate volume.
Common Treatment Areas in Gangnam
Botox treats forehead lines, glabellar frown lines (the "11" lines between eyebrows), and crow's feet. In Korea, masseter Botox for jawline slimming is one of the most requested procedures, using 50-100 units per session. Trapezius Botox for shoulder slimming typically requires 100 units. These muscle-relaxing applications produce visible changes within 2-4 weeks as the targeted muscles gradually reduce in size.
Filler treatment areas include the nasolabial folds, chin augmentation, lip enhancement, under-eye hollows, temple restoration, and forehead contouring. Each area requires a different filler viscosity and injection technique. Lip fillers typically use 1cc of soft hyaluronic acid, while chin and jawline work may require 2-3cc of a firmer product for structural support.
What to Expect During Treatment
A typical Botox session takes 10-15 minutes. The practitioner marks injection points, cleanses the skin, and delivers precise doses using a fine 30-32 gauge needle. Discomfort is minimal, often described as a brief pinch. No anesthesia is required for most Botox areas, though some patients request topical numbing cream applied 20 minutes before treatment.
Filler Injection Process
Filler procedures take 20-45 minutes depending on the number of areas treated. Most modern fillers contain lidocaine for built-in numbing. Practitioners use either needles or blunt-tip cannulas, with cannulas reducing bruising risk by approximately 60%. Post-treatment, gentle massage shapes the filler into position. Patients can typically return to daily activities immediately, though strenuous exercise should be avoided for 24-48 hours.
Duration and Maintenance Schedule
Botox effects last 3-6 months before muscle activity gradually returns. Regular maintenance every 4-6 months maintains consistent results. Some clinical evidence suggests that long-term Botox use (5+ years of consistent treatment) may extend duration between sessions as targeted muscles weaken over time. Ahn BK et al.

Filler longevity varies by product: hyaluronic acid fillers persist 6-18 months, Radiesse lasts 12-18 months, and Sculptra can maintain results for up to 24 months. High-movement areas like lips break down filler faster than static areas like the cheeks. RE:BERRY Gangnam Aesthetic Medicine Specialist Yoon-Gon Ryu notes that combining both treatments in a single session allows comprehensive facial rejuvenation while minimizing total clinic visits.
Who Benefits from Botox and Fillers
Suitable candidates are generally healthy adults aged 25-65 seeking non-surgical facial improvement. Botox is most effective for dynamic wrinkles visible during expression, while fillers address static volume loss and structural deficits. Contraindications include pregnancy, neuromuscular disorders (for Botox), and active skin infections at injection sites. Patients taking blood thinners should disclose this, as it increases bruising risk.
The combination approach addresses multiple aging signs simultaneously. A patient with forehead wrinkles, lost cheek volume, and thinning lips might receive Botox to the forehead (20-30 units), hyaluronic acid filler to the cheeks (2cc), and lip filler (1cc) in a single 45-minute appointment. This multi-area strategy delivers natural-looking results because it restores facial harmony rather than treating isolated concerns.
