Nos piercing maintenance

Hi! I got my nose pierced three months ago and have been diligently cleaning it with a saline spray in my nose and saline on a towel on the outside. I've been keeping the piercing dry as per my piercer's instructions. However, with the onset of winter, my nose has become very dry. This has led to a lot of bloody noses lately. I typically use Vaseline to moisturize my nose, but I don't want to cause an infection in my piercing. I have noticed that my piercing has started to crust, bleed, and form a small bump. I'm not sure what to do. Please offer advice on how to prevent infections and clean my nose during the dry winter months while also keeping it moisturized to avoid more bloody noses. Thank you!
