How to Tell If a Tattoo Is Infected
Signs that a tattoo may be infected include redness that spreads or gets worse, increasing swelling or pain, pus, a bad smell, warmth around the area, red streaks, or fever and chills. The key difference from normal healing is direction. Normal healing gets better day by day, while an infection usually gets worse. If you notice these signs, contact a doctor. Only a healthcare provider can diagnose and treat an infection.
This guide explains the warning signs, how to tell them apart from normal healing and how to lower your risk. It’s general information, not medical advice.
Important: If you have a fever, red streaks spreading from the tattoo or rapidly worsening symptoms, seek medical care right away.
Key Takeaways
Warning signs: Spreading redness, worsening swelling or pain, pus, a bad smell, heat, red streaks or fever.
Healing vs. infection: Normal healing improves day by day, while infection tends to get worse.
Timing varies: Some infections show up within days, while others, like certain bacterial infections linked to contaminated ink, can appear later.
See a doctor: Don’t try to diagnose or treat a suspected infection yourself.
Prevention: Choose a clean, reputable tattoo studio and follow your aftercare instructions closely.
What Does It Mean When a Tattoo Is Infected?
A tattoo infection happens when germs, usually bacteria, get into the skin through the wound a tattoo creates and cause your body to react.
Every new tattoo is an open wound. The needle punctures the skin many times to deposit ink, and the skin needs time to repair. If germs get in during the tattoo or while it heals, an infection can develop.
Mayo Clinic notes that a skin infection is possible after getting a tattoo, sometimes because of contaminated ink or equipment that isn’t sterilized correctly. Most infections are preventable with clean practices and good aftercare.
What Are the Signs a Tattoo Is Infected?
The most common warning signs are redness that spreads, worsening swelling, warmth, pus, a bad smell, red streaks, and fever or chills.
Watch for:
Spreading redness: Redness that grows larger instead of fading after a few days.
Worsening swelling or pain: Puffiness or soreness that increases instead of calming down.
Pus or thick discharge: Yellow or green fluid, rather than the thin, clear fluid of early healing.
Heat: The area feels noticeably hot.
A bad smell coming from the tattoo.
Red streaks spreading outward from the tattoo.
Fever or chills: Whole-body symptoms that need prompt medical attention.
Persistent bumps or rash: Red bumps or nodules within the tattoo that don’t go away.
That last sign matters because not every infection shows up right away. In a 2011 to 2012 investigation, the CDC found that infections linked to contaminated tattoo ink can range from mild inflammation (e.g., rash, papules, or nodules) to severe abscesses requiring extensive and multiple surgical debridements. In one New York case, a persistent rash began about a week after the tattoo. cdc
Some symptoms, like an itchy rash, can also come from an allergic reaction rather than an infection. Mayo Clinic notes that tattoo ink can cause allergic skin reactions, sometimes years later. A doctor can tell the difference.
Warning: Red streaks spreading from the tattoo, especially with fever, can signal a serious infection. Seek medical care right away.
How Do You Tell Normal Healing From an Infection?
Normal healing usually involves mild redness, tenderness, swelling and some clear fluid in the first few days, all of which improve over time. Possible infection signs tend to get worse instead.
In the first two to three days, some discomfort is expected. Mild redness, light swelling and thin, clear or slightly cloudy fluid are common. Over the next week or two, flaking and itching are typical as the skin repairs itself. Mayo Clinic notes that most tattoos take about two weeks to heal.
A simple rule: healing trends better each day. If your tattoo looked calmer on day two and worse on day five, contact a doctor.
The American Academy of Dermatology also shares tips for caring for tattooed skin as it heals.
How Do You Check a Tattoo for Infection Step by Step?
Wash your hands, look closely in good light, compare it with how it looked the day before, check your temperature and contact a doctor if anything is getting worse.
Step 1: Wash your hands. Avoid adding germs while you check.
Step 2: Look in good light. Note any redness, swelling or discharge.
Step 3: Notice warmth. Check whether the area feels unusually hot compared with the skin around it.
Step 4: Compare with yesterday. A daily photo makes it easy to see whether things are improving or getting worse.
Step 5: Check for discharge and odor. Pus, thick fluid or a bad smell are reasons to call a doctor.
Step 6: Take your temperature. Fever is a reason to seek medical care promptly.
Step 7: Contact a doctor if needed. If symptoms are getting worse, or you have fever or red streaks, call a healthcare provider. Don’t wait it out.
Pro Tip: Take a dated photo each day during the first two weeks. A visual timeline helps you and your doctor see how things have changed.
Why Do Tattoos Get Infected in the First Place?
Tattoo infections are usually linked to contaminated equipment, contaminated ink, unclean surfaces, unwashed hands or problems with aftercare.
Common causes include:
Unsterile needles or equipment: Reused or improperly cleaned tools can spread germs.
Contaminated ink or water: The CDC notes that contamination can occur during manufacturing or when inks are diluted with nonsterile water by tattoo artists. In the New York cluster the CDC investigated, a total of 19 infections were identified, including 14 confirmed with M. chelonae.
Dirty work surfaces: Skipping proper disinfection raises the risk.
Unwashed hands: Germs can be introduced during or after the session.
Aftercare problems: Picking scabs, soaking the tattoo or not keeping it clean can let germs in.
Professional tattoo studios follow the OSHA Bloodborne Pathogens Standard for sterilization and cross-contamination control. The U.S. Food and Drug Administration also advises consumers to ask their Tattoo Artist or tattoo studio about the inks they use.
How Can You Prevent a Tattoo Infection?
Choose a clean, reputable tattoo studio, make sure sterile single-use equipment is used and follow your Tattoo Artist’s aftercare instructions closely.
Before you book, do your homework. A reputable tattoo studio should open fresh needles in front of you, change gloves as needed and keep a clean, organized station. If anything feels off, it’s fine to walk away.
After your session:
Keep it covered for as long as your Tattoo Artist advises.
Wash gently with clean hands and a mild, fragrance-free soap.
Moisturize lightly with the product your Tattoo Artist recommends.
Don’t pick or scratch scabs or flaking skin.
Avoid soaking in pools, hot tubs, baths or open water while it heals.
