Keloid Scar

A keloid scar is a type of raised scar that forms after an injury to the skin has healed. It is characterized by an overgrowth of scar tissue, which can be itchy, painful, and unsightly.

Causes and Risk Factors

Keloid scars are caused by an abnormal healing process, where the body produces too much collagen, a protein that helps to repair damaged skin. This can occur after any type of injury, including cuts, burns, acne, and surgical incisions. Certain factors can increase the risk of developing keloid scars, such as:

• Genetic predisposition
• Darker skin tone
• Younger age
• Pregnancy
• Hormonal changes

Symptoms

Keloid scars can appear anywhere on the body, but are most common on the ears, chest, back, and shoulders. They can be:

• Raised and lumpy
• Red or purple in color
• Itchy or painful
• Larger than the original wound

Treatment Options

Treatment for keloid scars depends on the size, location, and severity of the scar. Common treatment options include:

• Silicone gel or sheeting to flatten the scar
• Corticosteroid injections to reduce inflammation
• Laser therapy to reduce redness and flatten the scar
• Surgery to remove the scar, followed by radiation therapy to prevent recurrence
• Pressure earrings or garments to flatten the scar

Prevention

To prevent keloid scars from forming, it is essential to:

• Keep wounds clean and covered
• Avoid picking at scabs or scratching the wound
• Use sunscreen to protect the skin from further damage
• Avoid tight clothing that can irritate the skin

Complications

If left untreated, keloid scars can lead to complications such as:

• Chronic pain and discomfort
• Emotional distress and self-consciousness
• Infection or skin irritation
• Limited mobility or flexibility
