Botulinum Toxin Type A

by Dr. Cárdenas

Botulinum toxin type A or botox is an effective treatment for wrinkles. When botulinum toxin is injected, the skin around the treated area will appear smoother and with fewer wrinkles.

What is it?

It is a highly purified protein that, in very low doses, does not produce harmful effects despite its origin. When botulinum toxin is injected into a specific muscle, it decreases its activity, inhibiting its contraction. In this way, the muscle is temporarily paralyzed and relaxes, preventing or improving expression wrinkles. Botulinum toxin type A allows normal movement of the untreated areas of the face.


Treatment of wrinkles with botulinum toxin type A has several benefits:

  • It is a non-permanent treatment, but after which wrinkles never reappear with greater intensity than before.
  • You will still be able to express your emotions, smile and frown, but within days of treatment, the wrinkles around the treated areas appear softer and less pronounced.
  • It is a minimally invasive treatment.

In addition to its use to treat wrinkles, botulinum toxin type A also has other uses:

  • Bruxism: Botox can be used to treat bruxism, which is involuntary teeth grinding or clenching.
  • Hyperhidrosis: Botulinum toxin type A can help control hyperhidrosis, which is excessive sweating.
  • Nefertiti’s Neck: Through the strategic application of Botox, a lifting effect can be obtained in the neck, known as “Nefertiti’s Neck”.

How and for what?

Botulinum toxin type A treatment prevents muscle movements from repeatedly wrinkling the skin in the treated area.

It is possible that the response to treatment may be different from that of other people. Some people see results the day after treatment with botulinum toxin type A but most people notice the result after 5-7 days. Sometimes it takes up to two weeks to see that the treatment is completely effective.


The results last, on average, 4 to 5 months after which the muscles progressively regain their contraction strength and, therefore, wrinkles reappear again, but never with greater intensity than before its application. It is not a permanent treatment, its effects are reversible.

It is recommended not to repeat the treatment in an interval of less than 12 weeks between sessions. The treatment is viable for people between 18 and 65 years old.

Post Treatment

Rubbing or massaging the treated area should be avoided for at least 24 hours after treatment, as well as intense exercise and saunas for the first 48 hours. It is normal for small red marks to appear on the skin in the treated area, as well as slight swelling, but they usually disappear within a few days. It is important to follow the doctor’s instructions to obtain the best results.
