What's the difference between a surface and a dermal piercing?
Dermal Piercings
A piercing with no "exit point"
Dermal anchors are inserted beneath the dermal layer of your skin.
Dermal jewelry is anchored by a base that sits beneath the skin, leaving the top exposed for a decorative jewelry end.
Dermal anchors may have a round base or a footed (bar-like) base with small holes in them - as your piercing heals, your tissue will grow through these holes, helping to keep your dermal snug and in-place.
Can be inserted with either a needle or a biopsy punch.
Biopsy punch method - a small swath (punch) of skin is removed to allow for space for the dermal anchor to sit. Typically less painful overall and tends to reject less often than other methods.
Needle method - your piercer will create a space for the dermal anchor underneath the dermal layer of skin. You may have to use this method depending on your state/country of origin and its individual laws.
What's the difference between a dermal and a surface piercing?
One main difference - surface piercings have an exit point
Surface piercings are typically fitted with a surface bar
During a surface piercing procedure, the piercer will pinch the skin and stick the needle through the pinched area.
If you are using a surface bar for a piercing, staple-shaped surface bar is most appropriate.
Surface piercings and dermal piercings come with a significantly higher chance of rejection. They tend to suffer from snags which tend to set your piercings off on a journey of migration or rejection.
Surface bar might see more complications due to scarring.
Dermals are increasing in popularity over surface bars.
Both are considered long-term temporary piercings.
