Your case. You say you are spot on and the scars on legs and arms. Some of that is quite old and is from the chicken pox scar. I tell of your case. I asked my granddaughter is a pharmacist with pharmacy chains in the province. She said that if it is chicken pox scar from the new treatment and will not have a point or leave scars. But if left untreated until it's quite old and worthy treatment. It is unlikely to be back to the same. But it may have faded somewhat, and it would take quite a long time
