Unveiling Common Types of Skin Scarring: Your Guide to Effective Treatment

Scarring is a natural part of the skin’s healing process, but it can often leave individuals feeling self-conscious or uncomfortable. Understanding the different types of scars and available treatment options is crucial for those seeking to restore their skin’s appearance and confidence. Here, we delve into the most common types of skin scarring and address the questions patients commonly ask when exploring treatment options.

The principal causes of scarring include:

• Wounds and Injuries: Any form of injury to the skin, whether from accidents, cuts, burns, abrasions, or surgical incisions, can lead to scarring. The severity of the wound and how well it heals influence the resulting scar.
• Acne: Acne breakouts can cause inflammation and damage to the skin, resulting in various types of scarring, such as atrophic scars (depressions) or hypertrophic scars (raised scars).
• Atrophic Scars:
  • Ice Pick Scars: These are deep, narrow scars that resemble small puncture marks on the skin’s surface. They are typically narrow and extend deep into the skin.
  • Boxcar Scars: Boxcar scars are broad depressions with sharply defined edges, resembling craters or box-like shapes on the skin. They are wider than ice pick scars and can vary in depth.
  • Rolling Scars: Rolling scars have a wavelike or undulating appearance and are caused by the pulling of underlying scar tissue beneath the skin’s surface. They create a shallow, wide depression on the skin.

• Hypertrophic Scars: The body develops hypertrophic scars when it produces excess collagen during the healing process. They may appear red or pink and can be itchy or uncomfortable. Unlike keloid scars, hypertrophic scars do not extend beyond the original wound site.
• Keloid Scars: Raised and thickened, keloid scars extend beyond the boundaries of the original acne lesion. They result from an overproduction of collagen during the healing process and may continue to grow. Keloids can be itchy, painful, and cosmetically bothersome.
• Infections: Skin infections, particularly those that are deep or severe, can lead to scarring as the body’s immune response attempts to heal the affected area.
• Skin Conditions: Certain skin conditions, such as chickenpox, shingles, and psoriasis, can cause scarring because of the body’s inflammatory response and the healing process of the skin.
• Surgical Procedures: Surgeries, whether elective or medically necessary, often result in scarring at the site of incision or tissue manipulation. The extent of scarring can vary depending on factors, such as surgical technique and individual healing characteristics.
• Trauma and Accidents: Traumatic injuries, including lacerations, punctures, and blunt force trauma, can cause scarring as the skin attempts to repair itself.
• Genetic Predisposition: Some individuals may be more prone to developing scars because of genetic factors that influence collagen production and skin healing processes.
• Foreign Bodies: Presence of foreign objects or debris within a wound can interfere with the healing process and increase the likelihood of scarring. Common examples of this include piercings in the upper part of the ears. 

Types of Skin Scarring:

• Hypertrophic Scars: These scars appear raised and often have a red or pink colour. They form when the body produces too much collagen during the healing process.
• Atrophic Scars: A loss of tissue characterises atrophic scars, resulting in a depression or indentation in the skin. These include ice pick scars, boxcar scars, and rolling scars commonly seen in people living with acne.
• Keloid Scars: Keloids are thick, raised scars that extend beyond the original wound site. They can be itchy, painful, and may continue to grow.
• Contracture Scars: Typically resulting from burns, contracture scars tighten the skin, potentially impairing movement and causing discomfort.
• Stretch Marks (Striae): Stretch marks often occur because of rapid stretching of the skin, commonly during pregnancy or significant weight gain or loss. They appear as lines or streaks on the skin.
