A scar turning black can be due to a few reasons:
- Sun exposure: If a scar is exposed to sunlight during the healing process, it can become pigmented, leading to a darker appearance. This is because sunlight stimulates melanin production, the pigment responsible for skin color.
- Inflammation: Inflammation during the healing process can also contribute to a darker scar. This is often caused by infections or irritation.
- Genetics: Your skin's genetics and how your skin heals can influence scar color. People with darker skin tones are more prone to hyperpigmentation, a condition where the skin produces excess melanin, resulting in darker patches.
- Post-inflammatory hyperpigmentation (PIH): This is a common condition that occurs after skin injuries or inflammation. The body produces excess melanin in the affected area, leading to dark spots or scars.
It's important to note that:
- Dark scars are more common in people with darker skin tones.
- Scars may darken or lighten depending on the individual and the type of scar.
If you're concerned about a dark scar, it's best to consult a dermatologist. They can help identify the cause and recommend appropriate treatment options.
