The eyebrow piercing is usually placed perpendicular to the eyebrow.
Piercings placed vertically usually cause the ring to protrude.
Piercings that are slanted inwards (\ /) tend to make the ring lay
The depth of the piercing should be determined with regards to how
much tissue is available to support the piercing. Most eyebrow
piercings are usually between 1/4" and 3/8" wide. To avoid damaging
the nerves beneath the eyebrow the piercing should not be made much
deeper. Placing the piercing through the outermost half of the brow
will avoid damaging the Supraorbital nerve.
Because the brow is usually relatively flat, eyebrow piercings have a
greater tendency than other piercings to migrate or reject. If the
brow is completely flat and cannot be easily pinched, the tension of
the skin creates pressure on the jewelry which may cause the piercing
to migrate or even reject completely. In some cases the piercing will
shift or migrate slightly while healing but will eventually
settle. The piercing should not be made excessively deep on the
assumption that it will migrate into place.
Jewelry which is too thin is more easily rejected by the body and more
likely to tear the piercing if the jewelry is accidentally pulled.
Jewelry which is too heavy for the amount of tissue available can
cause the piercing to migrate or reject. Prolonged healing, scarring
and migration often result if the wearer sleeps on his/her piercings.
Initial jewelry: Captive bead rings in 18 to 14 gauge and 3/8" to
7/16" in diameter; the diameter should be at least 1/8" wider than
width of the piercing. No more than 1/4 of the ring should be through
the piercing. A ring which is too small in diameter will often cause
the piercing to migrate or scar.
Straight or curved barbells in 18 to 14 gauge and 5/16" to 7/16" in
length; the barbell should be at least 1/16" longer than the width of
the piercing. Straight barbells should not be used if the brow is
very flat. The balls will create pressure against the skin behind them
which often causes the piercing to migrate forward. A curved barbell
will eliminate pressure between the barbell balls and the skin.
Eyebrow retainers should not be worn in new piercings because they are
Eyebrow piercings often swell or bruise slightly during the first 24
to 48 hours.
