What is a Botulinum Toxin?

Botulinum Toxin acts by blocking the signal from nerves to the muscles that are injected. The injected muscle can no longer contract, or tighten, as forcefully as before, and this leads to a controlled relaxation of muscles. 

It is approved for treatment of frown lines on the forehead, crow’s feet, or lines around the eye, and axillary hyperhidrosis, or increased sweating armpits. 

Benefits of Botulinum Toxin

  • Temporary smoothing of facial wrinkles and improving your appearance
  • Severe underarm sweating
  • Cervical dystonia – a neurological disorder that causes severe neck and shoulder muscle contractions
  • Blepharospasm – uncontrollable blinking
  • Strabismus – misaligned eyes
  • Chronic migraine

Before and During the Procedure

Before undergoing Botulinum Toxin, Dr. Rodolfo Castillo board-certified plastic surgeon makes a detailed consultation and assessment. During this appointment, determine if you are a good candidate, explain the cosmetic injection procedure, discuss your expectations and symptoms you may have after the procedure.

Botulinum Toxin works by weakening or paralyzing certain muscles or by blocking certain nerves. Dr. Rodolfo Castillo uses a thin needle to inject tiny amounts of Botulinum Toxin into your skin or muscles. The number of injections needed depends on many factors as the area being treated and the gender’s patient.

After the Procedure and Recovering

Injections may also cause you feel much discomfort. The most common side effects are pain, swelling, or bruising at the injection site. Dr. Rodolfo Castillo might use ice and vibration anesthesia, which uses massage to reduce discomfort and numb the area.

Self-care

Following your Botulinum Toxin injections, Dr. Rodolfo Castillo will recommend you to:

  • Avoid rub or massage the treated areas for 24 hours to prevent the toxin from spread to a different area
  • Avoid sun if you have injections in the face
  • Do not use Botulinum Toxin if you are pregnant or breastfeeding

To maintain the effect, you will need regular follow-up injections with Dr. Rodolfo Castillo. The results typically last about six months to one year.
