Several factors can negatively impact scar healing and appearance. One of the most significant factors is sunlight exposure. Scars are more susceptible to ultraviolet light for over a year after injury, potentially leading to inflammation, altered pigmentation, and worsening of the scar.
Other factors that can negatively affect scars include:
- Excessive pulling or tension on the healing wound: This can lead to increased inflammation and scar formation.
- Infection: Infection can delay healing and increase the risk of scarring.
- Improper wound care: Using harsh chemicals or irritants on a healing wound can damage the skin and lead to scarring.
- Certain medications: Some medications, such as corticosteroids, can increase the risk of scarring.
- Keloid scarring: This type of scar is an overgrowth of collagen that can result in a raised, lumpy scar.
It's crucial to follow your doctor's instructions for wound care and avoid activities that could put unnecessary stress on the healing wound.
