Expression wrinkles are those that result from moving the same muscles many times.
There are different types of expression wrinkles of the nasolabial fold, which can be dynamic (primary) or gravitational (secondary):
- Dynamic wrinkles. They are produced as a consequence of a repetitive muscular movement, when we gesticulate. They are wrinkles that, at first, are only visible when we move these muscles. However, over time they become marked on the skin, becoming visible even without gesturing.
- Gravitational wrinkles. They appear as a natural result of aging, which decreases the ability to form collagen and elastin. In addition, a process of bone resorption also begins, which causes flaccidity and skin sagging.
How to treat facial wrinkles?
There are different treatments of choice for facial wrinkles. It will be the specialist in Aesthetic Medicine who will decide, taking into account the case and the type of wrinkle, the best technique.
Gravitational wrinkles can be treated with acid but also with other non-permanent products such as inducers of collagen and elastin formation, such as calcium hydroxyapatite and PDO tensor threads.
Botulinum toxin, treatment of choice for expression wrinkles
However, botulinum toxin is the treatment of choice to eliminate these wrinkles, especially those located around the eyes (known as crow’s feet), between the eyebrows and on the forehead. The treatment is done in consultation, in about 30 minutes.
It is a treatment that temporarily relaxes the muscles, reducing their activity and contraction. The botulinum toxin allows the untreated muscles to continue to move normally. Thus, one of the most frequently asked questions before undergoing this treatment is answered: you can laugh, cry and express emotions without any problem.
How long do the effects of botulinum toxin last?
Not everyone responds to treatment in the same way. Some people notice the results after 2-3 days, but some people do not see the results for about 15 days.
The results of the treatment usually last about 4-5 months, although there may be variability depending on each patient. There is no exact mathematical formula but there is an approximate formula, so it is estimated that two treatments per year are sufficient to maintain the results.
