Skin Tag Turned Black After Banding — Is That Normal?

You banded a skin tag two or three days ago, and now it's dark purple or black. Your first instinct is that something went wrong. It's the opposite: this is exactly what success looks like.

Why it turns black

The band stopped the tag's blood supply — that's the entire mechanism of ligation. Without blood, the tissue darkens the same way a bruise does, then dries out. The progression is predictable: red → purple → dark brown/black → shrivelled → gone. The black stage usually appears on days 2–5 and lasts until the tag detaches around days 7–14. (Full timeline here: how long banding takes, day by day.)

What to do while it's black

• Nothing, mostly. Leave the band and tag alone — no tugging, no "checking" twists.
• Keep it clean and dry. Normal showers are fine; pat dry gently.
• Loose clothing over the area if it's somewhere that rubs (neck collars, underarm seams).
• Let it fall on its own. Pulling a blackened tag off early is the most common cause of bleeding and a lasting mark.

After it falls: aftercare that prevents marks

Once the tag detaches you'll see a small pink spot. Keep it moisturised, don't pick at any tiny scab, and keep sun off it for a few weeks (fresh skin pigments easily — this is the step most people skip and the main cause of lingering marks). Covered in detail in our aftercare guide, which comes as a bonus with every Tagless kit order.

The rare cases that AREN'T normal

Colour change of the tag = normal. Problems show up in the skin around it:

• Spreading redness or warmth of the surrounding skin
• Pus or discharge
• Throbbing pain (vs the mild pressure of day one)
• Fever

Any of those: remove the band and get it looked at. These are rare and usually trace back to banding something that wasn't a simple skin tag or to broken skin at application.
