As we enter the cold season β this year, dovetailing with the season of That Other Virus β remember the best way to prevent βnose dandruffβ (dry skin flaking off your nose) is to liberally moisturise it with balm inside and out. (Not pretty, but effective β though do ditch the balm after your infectionβs cleared.) If you need to de-flake, soak skin and gently buff with a soft washcloth, then moisturise, moisturise, moisturise.
