Dear swthunky.madd4nab, welcome to hcm.
the marks due to chicken pox
usually disappear after a certain period of time without any interventions as such. the dark circles
may be because ur poorly nourished or sometimes seen if ur using spectacles since a time.
Its my humble request you to stop worrying about them and concentrate on ur fresh fruits, vegetables intake and also check on ur level of active schedule. wash ur face with mild face wash and hav a nutritious diet.
thank u. God bless You:-)
