A keloid is a raised, thick, and often shiny scar that forms due to excessive collagen production during the skin's healing process. Unlike regular scars, keloids grow beyond the boundaries of the original wound and do not regress naturally. They may be itchy, painful, or cause cosmetic concerns, and commonly appear on the chest, shoulders, back, earlobes, and jawline.

Keloids usually appear weeks to months after an injury and may show the following features:

Elevated Scar – Firm, raised, and shiny growth above the skin surface.

Hyperpigmentation – Red, purple, or darker than your natural skin tone.

Discomfort – May cause pain, tenderness, or itching.

Progressive Growth – Gradually enlarges over time beyond the injury site.

Keloids can occur in anyone, but they are more common in people with darker skin tones, individuals aged 10–30, and those with a family history of keloid formation. Ear piercings, tattoos, and acne scars are common triggers.
