  • Increase collagen production: Several of the fillers promote the natural production of collagen, which supports skin health .
  • They are not invasive: the needles used to infiltrate the substances are tiny and the procedure is similar to an injection of medicine. They do not cause pain, so they do not require anesthesia.
  • They are personalized: the technique consists of adapting the filling to what each skin requires . In fact, many of the infiltrated substances are produced by the body naturally.
  • Rest exemption: you do not have to stop the routine after facial injections. With some care is enough. Avoid direct sunlight and use makeup during the days indicated by the professional. Cleanse and moisturize according to the instructions.

Risks and Complications of Injectable Fillers

After a procedure performed under medical safety guidelines, there would be no greater risk with the fillers. However, it is likely to manifest secondary reactions, such as redness, erythema or allergies. Although these signs are short-lived, if any worsen, it is essential to see a doctor.

Other tips are to go to a service provider authorized and trained to apply dermal fillers, make sure they are pre-filled syringes, sealed and labeled by the country’s health authorities, as well as knowing from the professional the type of product to infiltrate.
