This article is from the Piercing FAQ, by Anne Greenblatt with numerous contributions by others.
Over-cleaning the piercing, failure to thoroughly rinse the piercing
after using a skin cleanser or soap, or using a skin cleanser or soap
that is too drying can cause the openings of the piercing to become
red, overly dry or cracked. Most piercings do not require cleaning
more often than 2 or 3 times a day. A light, greaseless moisturizer or
aloe vera gel may be applied to the skin surrounding the piercing, but
should not be allowed into the piercing. Please refer to Part 5 of the
Piercing FAQ for information about aftercare products.
Sensitivity to the aftercare product is usually indicated by extreme
itching and burning upon application of the product and may cause a
rash of small bumps around the piercing. If you suspect that you are
allergic to a particular product, discontinue its use, thoroughly
irrigate the piercing, and rinse the affected area with water. Consult
your piercer or refer to Part 5 of the FAQ for alternative aftercare
products. If the condition persists contact a physician.
Some people have noticed that the condition of their piercings
deteriorates or that the healing process is slowed when they move to
an area with harder water. The body usually adjusts to the change. If
the irritation continues, use bottled or distilled water until the
piercing has healed.
Laundry detergents containing stain-fighting enzymes should not be
used to wash clothing which is in direct contact with the piercing.
