A dermal piercing, also known as a microdermal anchor, is a body modification where jewelry is implanted partially beneath the skin’s surface. Unlike traditional piercings that have both an entry and exit point, a dermal piercing consists of a small anchor placed in the dermis layer with a decorative top visible externally. New wearers often notice a distinct, sometimes pungent smell emanating from the site. This odor is common with all types of piercings and is usually a normal biological process rather than a sign of a serious complication.
Why Piercings Produce Odor
The characteristic odor around a dermal piercing results from natural biological processes that create a buildup known colloquially as “piercing funk.” The skin continually sheds dead cells, primarily composed of the protein keratin. This keratin mixes with sebum, the oily substance secreted by the skin’s sebaceous glands for lubrication.
This mixture of dead skin, oil, and moisture creates a nutrient-rich environment for the bacteria residing on the skin’s surface. As these bacteria colonize the debris trapped around the anchor and beneath the jewelry, they produce volatile organic compounds. The release of these compounds causes the unpleasant smell.
Lymph fluid, which is part of the body’s natural healing response and appears as a clear or straw-colored discharge, also contributes to the odor when it mixes with trapped material. Since the dermal anchor creates a small, semi-enclosed space, this biological debris cannot simply rinse away. Regular, gentle cleaning is necessary to manage this accumulation and minimize the smell.
Recognizing Serious Issues and Infection
While a mild odor is a normal hygiene issue, a sudden or intense foul smell can signal a problem, such as an infection. A true bacterial infection is typically accompanied by specific symptoms beyond just a smell. Look for thick, discolored discharge that appears yellow or green, which is pus and differs from the clear or pale fluid of normal healing.
Infection is also characterized by excessive localized heat, throbbing pain, and swelling that worsens over time. If you observe red streaks radiating outward from the piercing site or experience fever, seek professional medical attention. Normal odor is localized and relieved by routine cleaning, while an infection’s symptoms persist and intensify.
Another concern is rejection, where the body perceives the anchor as a foreign object and attempts to push it out. Signs of rejection include the jewelry migrating from its original placement or the skin around the anchor becoming visibly thinner or taut. You may also notice the base of the jewelry becoming visible or the skin over the anchor appearing transparent. If rejection or infection is suspected, consult a professional piercer or a physician before removing the jewelry, as taking it out prematurely can trap an infection beneath the skin.
Essential Cleaning and Maintenance
To minimize the odor and maintain a healthy piercing, a consistent cleaning regimen is necessary. The most recommended cleaning agent is a sterile saline wound wash, which should contain only 0.9% sodium chloride and purified water. Gently spray the solution directly onto the piercing site and allow it to soak briefly to loosen any crusted debris.
After cleaning, it is important to dry the area thoroughly, as trapped moisture exacerbates bacterial growth and increases the odor. Use a clean, disposable product like non-woven gauze or a paper towel to gently pat the area dry. Avoid irritating products like alcohol, hydrogen peroxide, or harsh antibacterial soaps, as these can disrupt the skin’s natural healing process and cause further irritation.
Always wash your hands thoroughly before touching the dermal piercing. If the odor persists despite diligent cleaning, or if you are concerned about the integrity of the anchor, visit your piercer. They can assess the piercing and perform a more in-depth cleaning or advise on potential jewelry material changes if a sensitivity is suspected.
