Neuromodulators such as Botox or Dysport can be used to soften those lines over the lateral eyebrows caused by contraction of the frontalis muscle.
If you are referring to the COVID-19 vaccine, there is no contraindication to getting Botox 4 days prior to the vaccine. Studies have shown that patients who have had certain types of fillers have developed swelling of those fillers after the COVID-19 vaccine but this has not been reported with Botox injection.
There are several differences between the Vbeam laser and the Excel V laser. The first being the wavelength. The Vbeam is a 595nm Pulsed Dye Laser. The Excel V laser has 2 wavelengths, 532nm and 1064nm. Excel V’s wavelength is much better absorb by the red color (hemoglobin)in the vessels being treated, resulting in more heat getting into the vessels, and thus, more effective treatment. Typically, the longer the wavelength, the deeper the laser is capable of going. So basically, by the addition of the 1064 laser, spider veins, and deeper blue vessels of the face and legs can now be treated. Another difference is the way the lasers cool the epidermis, so the laser beam can heat the vessels and not the top of the skin. Vbeam has a cryogen or cool ice shot that comes out just prior to the laser beam to cool the skin. The Excel V has a sapphire cooling tip that allows for cooling of the exact area that is treated. It also allows for pre, parallel, and post pulse cooling, leading to a safer and more comfortable treatment, with less risk to the skin. In my experience, the Excel V is excellent at treating background redness and dilated blood vessels, both of which can be features of erythematotelangiectatic rosacea. However, flushing is more difficult to treat with either laser.
