Toxina botulínica o bótox
Information you should know before receiving a botulinum toxin and our experience:
What is Botox?
It is purified type A botulinum toxin used in cosmetic medicine. It is a protein applied in minimal doses in the muscles of the face and around the eyes to produce a relaxation effect in them.
How is it applied?
By injections. Through a very fine needle, applied in the zones we want to relax and in the dose (units) required to do so. We apply anaesthetic cream 10 min. before the treatment, to minimize the pain from the needle, although many patients don't need it.
How does it work?
It inhibits the formation of acetylcholine (a neurotransmitter responsible for muscle contraction). When the muscle does not contract, the wrinkle decreases or disappears. Over 5-6 months, this effect declines and the muscle goes back to secreting acetylcholine and contracts again, which makes the wrinkle reappear.
Are there contraindications?
Yes, for people who have neuromuscular diseases or are pregnant or nursing. It has also been observed that in people over 70 years of age, botulinum toxin is not very effective, because the muscules may be more atrophied and weaker than normal.
What precautions should I take after treatment?
Avoid cold air conditioning or very cold air on the zone (for example: air conditioning on an airplane, directly on the face), as this may enhance the effect of the botulinum toxin, especially in the first weeks. It is not necessary to massage after treatment.
Why do some people who have tried it not like it?
If Botox is applied appropriately in the correct dose and in the appropriate muscles, the result is very satisfactory. Normally we ask patients to come for a check up after 10 days to make sure that all is satisfactory.
