Keloids, raised scars extending beyond original injuries, form from various skin traumas, from piercings to burns. While keloid formation involves excess collagen production, the role of melanin remains under investigation. Understanding keloids is vital for treatment and prevention.
Anything causing scarring can trigger keloids.
- Body piercing (ear especially)
- Acne or chickenpox bouts (often on face, chest, or back)
- Burns
- Cuts, scrapes, or bug bites
- Deep wounds like punctures
- Skin inflammation diseases like folliculitis
- Tattoos
- Surgical, procedural, or injection wounds
- Shaving beard area
- “Spontaneous keloids” on uninjured skin are rare and may occur from minor unnoticed injuries, severe body inflammation, or certain medications. Excess collagen production leads to keloid growth.
Research into keloids continues.
Does melanin cause keloids?
Melanin, skin pigment, varies in production, influencing skin, hair, and eye color. Keloids are more common in darker-skinned individuals with more melanocytes. This suggests a potential link between melanin and keloids.
Some are more predisposed to keloids.
- African, Asian, or Latin-American descent: More prevalent in these groups, especially among ethnic Chinese.
- Family history: About one-third have relatives with keloids, more in African or Asian families.
- Age (10 to 30): Peak keloid development period, though possible at any age.
- Pregnancy: Hormonal changes increase keloid risk.
Understanding keloid causes aids treatment and prevention.
