The short answer to your question is that Juvederm in my opinion would not be a good choice for treating your glabella chicken pox scar for two reasons. For one, Juvederm is not an ideal lifting filler. Better choices would be Restylane Lyft, which I would opt for in my Upper East Side Manhattan practice, or Hyaluronica 2, which would be my go-to for this in my Israel satellite facility, where a far greater number of regulatory agency approved fillers are available. More importantly, no filler by itself. is likely to be able to adequately lift a heavily tethered down chicken pox scar. More likely the filler would spread to the peripheryof the scar, and in fact a donut like effect may result in which the periphery of the scar would project even more than before, in effect accentuating the central depression of the pox scar. In order to avoid this, subcision lifting can be performed to break up the tethering scar collagen below responsible for pulling the scar downward. This alone may be used to elevate the base of the scar, but in conjunction with the fillers mentioned above is more likely to result in a more acceptable cosmetic improvement. Make sure to seek consultation and treatment from a board certified aesthetic physician. Best of luck.
