Is it ok for my 7 month old earlobe piercing to have crust? what should I do to stop it?

Bathe it with Aloe Vera and ensure you use gold plated or pure gold studs or earrings. Earrings with nickel in them can cause problems.

If it doesn't clear up within a few days, pop along to see your Doctor.

You have a slight metals allergy. Try using something with a gold plating.

You should bathe it every day in warm salt water I was told.

Coat it with lubriderm daily.
