Some beauty seekers have asked on the internet how long after having hyaluronic acid filler and botulinum toxin wrinkle removal can they do dermatological instruments such as red and blue light, radio frequency and Thermage? First of all, for Botox, you can do whatever you want after the injection, there is no need to pay special attention to the problem. On the day of injection and the day after the operation, do not rub the injection site, as the injected drug has not been completely absorbed at this time, which may lead to local spread. For example, if you use botulinum toxin to treat crow’s feet, if you keep rubbing and pressing after the injection, you may rub the drug into the eyes, causing the botulinum toxin to penetrate the eye muscles, which will cause the muscles to lose strength and form strabismus after the eye muscles are paralyzed. For hyaluronic acid, do not use hot-melting instruments after injection. Hot-melting instruments will promote the absorption of hyaluronic acid, which is, in layman’s terms, a waste of time. Therefore, after hyaluronic acid filler, do not use radiofrequency or Thermage treatment on the filled area. For red and blue light, its main function is to reduce swelling. Generally there is no need to use red and blue light to supplement the treatment after hyaluronic acid filler or Botox injection, but of course if the red and blue light treatment is free and included in the package, it can be done.
