Scars can be raised or sunken depending on the type and severity of the injury that caused the scar, as well as the body's natural healing process. Here are some common factors that can contribute to raised or sunken scars:
- Hypertrophic scars: These are raised, thick, and red scars that develop when the body produces too much collagen during the healing process.
- Keloid scars: These are similar to hypertrophic scars, but they continue to grow beyond the original injury site and can be larger than the original wound. Keloids are more common in people with darker skin tones.
- Infection or inflammation: If a wound becomes infected or inflamed during the healing process, it can lead to the formation of raised scars.
- Atrophic scars: These are sunken scars that form when the skin doesn't produce enough collagen during the healing process. Atrophic scars are commonly seen in acne scars.
- Surgery or trauma: If the injury that caused the scar removes a significant amount of tissue, it can lead to a sunken scar.
- Aging: As we age, the skin loses collagen and elasticity, which can cause scars to become sunken and more noticeable.
In some cases, scars can be treated with medical procedures such as laser therapy, dermal fillers, or surgical revision to improve their appearance. It's best to consult with a dermatologist or plastic surgeon to determine the best treatment options for your specific type of scar.
