Botulinum Toxin (BTx) Injections at Evita Clinic
Botulinum Toxin (BTx) works by temporarily blocking nerve signals to targeted muscles, causing them to relax. The result is a smoother, more refined appearance—without surgery or downtime. At Evita Clinic, BTx injections are performed by experienced medical staff with precision dosing tailored to each patient’s anatomy.
Each session typically takes less than 15 minutes, and results become visible within 3–7 days, lasting approximately 4–6 months depending on the treatment area and individual response.
Treatment Areas

Facial Rejuvenation
BTx effectively softens expression lines caused by repeated muscle movement. Commonly treated areas include:
- Forehead lines — frontalis muscle relaxation for a smoother brow
- Frown lines — reduces the “11 lines” between the eyebrows
- Crow’s feet — softens fine lines around the outer corners of the eyes
- Cobblestone chin — smooths dimpling of the mentalis muscle
Only the wrinkle-producing muscles are targeted, preserving natural facial expressions throughout.
Masseter Reduction (Square Jaw)
Overdeveloped masseter muscles can create a wide, square jaw appearance. BTx injections into the masseter muscle cause it to gradually reduce in size, resulting in a slimmer, more oval facial contour—without surgery.
- Dosage: 40–60 IU per side
- Results visible within 4–6 weeks
- Ideal for patients with jaw clenching (bruxism) as well


Calf Slimming
Bulky calves caused by overdeveloped gastrocnemius muscles can be slimmed non-surgically with BTx. Regular injections gradually reduce muscle volume, creating longer, leaner-looking legs.
- Dosage: 200 IU total (gastrocnemius muscle)
- Results appear over 4–8 weeks
- Popular among patients seeking leg contouring without surgery
Trapezius Slimming
Trapezius (Trap) BTx relaxes the upper trapezius muscle, reducing the bulky shoulder-neck appearance and creating a more elongated, elegant neckline. It may also help relieve chronic neck and shoulder tension.
- Dosage: 80 IU (upper trapezius)


Hyperhidrosis
Trapezius (Trap) BTx relaxes the upper trapezius muscle, reducing the bulky shoulder-neck appearance and creating a more elongated, elegant neckline. It may also help relieve chronic neck and shoulder tension.
- Dosage: 80 IU (upper trapezius)
Axillary Hyperhidrosis (Excessive Underarm Sweating) is effectively controlled with BTx injections into the sweat glands of the underarm area. Results typically last 6–12 months.
