Types of Tattoo Scarring
Hypertrophic Scarring
The most common type of tattoo scarring. Hypertrophic scars are raised, firm lines of scar tissue that form along the tattooed areas — particularly along line work where the needle made the most concentrated passes. The scar tissue remains within the boundaries of the original wound. Hypertrophic scars often soften and flatten over time (6-12 months), though they may never fully return to normal skin level.
Atrophic Scarring
Less common in tattooing. Atrophic scars are indented or depressed areas where tissue was lost or inadequately replaced during healing. In tattooing, this can occur in areas of severe overworked skin where the dermis was significantly damaged and healed with less tissue volume than the surrounding area.
Keloid Scarring
Keloid scars are an abnormal overgrowth of scar tissue that extends beyond the boundaries of the original wound. Keloids are driven by genetics — certain individuals (particularly those with darker skin tones) are predisposed to keloid formation. Keloid scars from tattoos can become large, raised, and uncomfortable, and they are the most difficult type to treat.
Causes of Tattoo Scarring
Artist-Side Causes
- Overworking the skin: Too many passes, too much pressure, or too high voltage — the primary cause of tattoo scarring
- Incorrect needle depth: Tattooing too deep penetrates into the subcutaneous fat layer below the dermis, causing excessive tissue damage
- Dull or defective needles: Needles that tear rather than puncture cleanly create more tissue damage per stroke
- Excessive session length: Working a single area for too long without allowing tissue to rest between passes
Client-Side Causes
- Picking scabs or peeling skin: Prematurely removing scabs tears the healing dermis, triggering excessive scar tissue formation
- Infection: Infected tattoos heal through intensive scarring as the body fights the pathogen
- Poor aftercare: Inadequate cleaning, over-moisturizing, sun exposure, or physical trauma to the healing tattoo
- Genetic predisposition: Some people produce excessive collagen during wound healing regardless of how well the tattoo was executed
- Allergic reaction: Reactions to specific ink pigments can cause localized scarring in the affected color areas
Prevention
Tattoo scarring is largely preventable through proper technique and aftercare:
For Artists
- Use appropriate voltage for the technique — never higher than necessary
- Monitor skin response during the session; stop when signs of overwork appear
- Use sharp, quality needles that puncture cleanly
- Match needle configuration to the task (magnums for fill, not liners)
- Plan touch-up sessions rather than overworking in a single sitting
- Adjust technique for thin-skinned areas (inner arm, ribs, neck)
- Ask about client history of keloid scarring before beginning work
For Clients
- Follow aftercare instructions consistently
- Never pick, pull, or scratch healing skin or scabs
- Protect healing tattoos from sun exposure, contaminants, and physical impact
- Disclose any history of keloid scarring or abnormal wound healing to your artist before the session
- Seek medical attention promptly if infection signs appear
Practical Implications for Artists
Always conduct a brief client intake that includes questions about scarring history, keloid tendency, and skin conditions. A client who mentions prior keloid scarring should receive detailed counseling about the risk — and for clients with known keloid predisposition, consider starting with a small test tattoo in an inconspicuous area before committing to a large piece.
Document your technique parameters (voltage, needle config, session duration) for each client. If scarring occurs, this documentation helps identify the cause and adjust for future sessions. It also protects you professionally if a client questions the quality of your work.
If a client returns with scarring, assess the cause objectively. If it was technique-related (overwork, incorrect depth), take responsibility, offer corrective treatment after full healing, and adjust your approach. If it was aftercare-related, reinforce your aftercare protocol for future clients. If the client has an unknown genetic predisposition, discuss the situation honestly and recommend dermatological consultation.
Treatment Options for Existing Tattoo Scarring
If scarring has already occurred, several treatment options exist (all require consultation with a dermatologist):
- Silicone sheets/gel: Over-the-counter silicone products can help flatten and soften hypertrophic scars over weeks-months of consistent use
- Corticosteroid injections: A dermatologist can inject steroid solutions to reduce inflammation and flatten raised scars
- Laser treatment: Fractional laser therapy can improve scar texture and reduce redness
- Microneedling: Controlled dermal stimulation can trigger collagen remodeling that improves scar appearance
- Time: Many hypertrophic scars improve significantly on their own over 6-18 months as the scar tissue matures and softens
Frequently Asked Questions
Is some scarring normal after a tattoo?
A well-executed tattoo with proper aftercare should heal flat and smooth, without noticeable scarring. Slight textural difference between tattooed and untattooed skin is normal, but visible raised lines, bumps, or rough texture is not. If you can feel the tattoo design with your fingers when running them over the skin surface, some degree of scarring has occurred.
Can a scarred tattoo be fixed?
Scar tissue from a tattoo can be improved but not fully reversed. After the scar has matured (6-12 months), dermatological treatments like silicone therapy, steroid injections, or laser treatment can reduce the scar's prominence. The tattoo can sometimes be reworked by a skilled artist after the scar tissue stabilizes, though ink retention in scar tissue is less predictable than in normal skin.
How long does it take for tattoo scarring to appear?
Tattoo scarring typically becomes apparent during or shortly after the healing process — within 4-8 weeks. During healing, raised areas, rough texture, or unusual firmness may develop. However, scar appearance can change over 6-18 months as the tissue matures. Some scars that appear prominent at 2 months may flatten significantly by 12 months. Keloid scars may continue growing for months after the initial healing period.
Does tattoo placement affect scarring risk?
Yes. Areas with thinner skin (inner arm, ribs, neck, feet, hands) are more prone to scarring because the dermis is less robust and more easily overworked. Areas that experience regular movement or friction (joints, waistline) are also at higher risk because mechanical stress during healing can promote excessive scar tissue formation. The upper chest and shoulders are known keloid-prone areas even in non-predisposed individuals.
Can I tattoo over scar tissue?
Yes, scar tissue can be tattooed, but it requires an experienced artist and adjusted technique. Scar tissue is denser and less uniform than normal skin — ink absorbs differently, often requiring more passes or different voltage settings. Wait at least 12-18 months for scar tissue to fully mature before tattooing over it. Expect that color and detail may be less consistent than on normal skin. A test patch is recommended before committing to a large design over scarred areas.
