Hi !! Your son is adorable.
The V Beam has a 5 mm,7mm or 10mm spot size. The cooling and pulse duration can also be varied. The wavelength is 595 nm.
My daughter has been treated with the V Beam and for the first year of her life she did not even bruise. Not a bruise on her but she had great fading.
Everyone is different and responds differently.
He looks wonderful. Good luck and happy healing and fading to your little guy.
