A dark bump hanging off your neck is almost certainly a skin tag. A cluster of flat dark papules spreading across your cheekbones is almost certainly DPN. But on melanin-rich skin, both can look strikingly similar, both tend to show up together, and both cause real confusion. This page draws the line between them clearly, then explains what to do about each one.
For the full picture on DPN specifically, start with the DPN removal safety guide. This page is the identification and comparison question.
Key takeaways
Shape, stalk, and location are the three cues that separate skin tags from DPN.
- Skin tags hang on a thin stalk in friction zones (neck, underarms, groin).
- DPN papules sit flat on the skin surface in a cluster, mostly on the upper face.
- On melanin-rich skin, both conditions frequently appear together in the same person.
- Professional practitioners like Ren routinely treat skin tags and DPN in the same session.
- Any dark lesion that does not fit either profile cleanly should be seen by a dermatologist.
The core differences: what each one looks like
These two conditions are distinct in structure. The confusion arises because both are benign, both appear more often on melanin-rich skin, and both can appear on the neck at the same time. Look at each one on its own terms first.
Skin tags (acrochordon)
A skin tag is a small, soft growth attached to the skin by a thin stalk called a peduncle. The tag itself is compressible and hangs away from the skin when lifted. It is not flat against the surface. On lighter skin, skin tags are usually flesh-toned. On melanin-rich skin, they often darken to a brown or near-black color, which is the main reason they get mistaken for DPN when someone glances in the mirror.
Skin tags range from about 1mm to 5mm in size and occasionally grow larger. They are not painful unless caught on clothing or jewelry. According to the American Academy of Dermatology, skin tags are extremely common and completely benign, with no risk of becoming cancerous.
DPN (dermatosis papulosa nigra)
DPN papules are flat to very slightly raised growths that sit directly on the skin surface. There is no stalk. The papules do not hang. They cluster in groups, typically spreading across the cheeks, forehead, temples, and around the eyes. On melanin-rich skin, they appear brown to dark brown or black. NIH MedlinePlus notes that DPN occurs almost exclusively in people with darker skin tones and is considered a benign variant of seborrheic keratosis.
A single DPN papule can be small enough to look like a skin tag at a glance. The difference becomes clear when you look at the whole picture: DPN presents as a field of small similar-looking papules sitting flush to the skin, not individual hanging tags attached by stalks.
Location clues: where each one tends to appear
Location is often the fastest diagnostic cue before you even examine texture or shape. Skin tags cluster in areas where skin rubs against skin or clothing: the neck (especially the sides and back), the underarms, the groin, the eyelids, and under the breasts. They appear wherever friction is consistent. For a detailed breakdown by body zone, see OcuraLife's skin tags locations guide.
DPN concentrates on the upper face. The cheeks, the temples, the forehead, and the area around the eyes are the classic DPN distribution zones. As DPN progresses, papules can spread to the neck and chest, which is where the overlap with skin tags gets visually confusing. For the DPN location picture, see the DPN complete guide.
The neck is the overlap zone. Both conditions favor it, for different reasons: DPN spreads there as the condition progresses, and skin tags form there due to collar friction. Someone with both conditions will often see them in proximity at the neckline, which reinforces the confusion.
Why melanin-rich skin sees both conditions together
DPN is a condition of melanin-rich skin. It appears almost exclusively in people with Fitzpatrick IV through VI skin tones and carries a genetic component: if your mother or grandmother had it, you are more likely to develop it too. Skin tags, by contrast, appear across all skin types but are more visually prominent and sometimes more numerous on darker skin, partly because the tags darken with the skin and stand out more clearly.
The result is a population of melanin-rich adults who look in the mirror and see dark bumps of multiple types at once: flat DPN papules on the face, hanging skin tags on the neck, and sometimes both in the same neck zone. Searches like "black skin tag" and "dark skin tag" often come from people who have one or both conditions and are trying to figure out what they are looking at. This page answers that question.
Can you have skin tags and DPN at the same time?
Yes. Having both is common and well-documented in clinical practice. Lorenda Toran (Ren), a Houston-based cautery technician, 11x award-winning tattoo artist, and OcuraLife affiliate who works primarily with melanin-rich skin, routinely treats skin tags and DPN in the same session because clients present with both. The two conditions are biologically unrelated, but they share a skin type and often appear simultaneously in adults over 35. When a client books a removal session for "dark bumps," they frequently have a mix of both types and leave the session with both addressed.
The practical takeaway: if you have both, you do not need two separate plans. The same plasma pen technique addresses both small confirmed skin tags and DPN papules in a single pass.
Removal approach: what works for each condition
Removal for skin tags
Small confirmed skin tags under about 3mm have several at-home options, the most precise of which is plasma pen treatment. The pen delivers a focused plasma arc to the base of the stalk, disrupting the tag at the attachment point. A small scab forms within a few days and falls off on its own, taking the tag with it. Clinic options for skin tags include snip removal (scissors), ligation (tying off the stalk), and cryotherapy (freezing). For complete context on skin tag anatomy and locations, see OcuraLife's skin tags guide.
Removal for DPN
The at-home standard for confirmed DPN is the plasma pen. The device delivers focused plasma energy directly to each papule at the skin surface. A protective scab forms between Day 3 and Day 7, then falls off on its own. By Week 2 to Week 3 the treated area reveals clearer skin. For the complete protocol for melanin-rich skin, including how to minimize post-inflammatory hyperpigmentation risk, see the DPN removal safety guide. For the day-by-day healing timeline, see the DPN aftercare guide.
If a bump hangs on a stalk in a friction zone, it is almost certainly a skin tag. If flat dark papules are clustered on your cheeks or forehead, it is almost certainly DPN. Both respond to the same tool.
When to see a dermatologist
Not every dark lesion on melanin-rich skin is a skin tag or DPN. See a dermatologist if the lesion you are looking at:
- Does not clearly match the profile of either a stalked skin tag or a flat DPN papule.
- Has irregular borders, asymmetry, or multiple colors within the same lesion.
- Bleeds on its own, crusts, or has not healed after weeks.
- Is changing in size, shape, or color over days or weeks.
- Has a rolled, ulcerated, or pearly border (possible basal cell carcinoma mimic).
- Is a dark or pigmented lesion that does not fit either profile cleanly. Melanoma and dysplastic nevi can occasionally be mistaken for darkly pigmented tags or DPN on melanin-rich skin. When in doubt, have a dermatologist look before treating anything at home.

The bottom line
Skin tags hang on stalks in friction zones. DPN papules sit flat on the skin in clusters, mostly on the upper face. On melanin-rich skin, both conditions darken and both can appear at the same time. The physical structure of each, stalk versus flat papule, is the fastest way to tell them apart. Both respond to the same at-home plasma pen treatment. If a dark lesion does not clearly match one of those two profiles, see a dermatologist before treating. For the complete DPN protocol, see the DPN removal safety guide.
