Understanding Acne and Surgical Scarring: Causes and Treatment Options
1. Acne Scarring
Acne scarring occurs when severe acne, such as cystic or nodular acne, causes damage to the skin’s tissue. As the skin attempts to heal, it can form scar tissue, leading to different types of scars.
Types of Acne Scars:
- Atrophic Scars: These are indentations in the skin caused by a loss of tissue.
- Ice Pick Scars: Deep, narrow scars that resemble small holes in the skin.
- Boxcar Scars: Broader, shallow scars with sharp edges, giving the skin a pitted appearance.
- Rolling Scars: Wave-like depressions that create an uneven skin texture.
- Hypertrophic or Keloid Scars: Raised scars that form when excess collagen is produced during the healing process. They are more common on the chest, back, and shoulders.
2. Surgical Scarring
Surgical scars form as part of the natural healing process following an incision. The severity and appearance of a surgical scar depend on the type of surgery, the skill of the surgeon, genetics, and aftercare. Over time, surgical scars may improve, but they can remain prominent or become hypertrophic or keloid.
Types of Surgical Scars:
- Linear Scars: The most common type of surgical scar, often a straight line, that forms as the skin heals after being sutured.
- Hypertrophic Scars: Raised, thickened scars that stay within the boundaries of the original incision.
- Keloid Scars: Similar to hypertrophic scars but grow beyond the original wound, becoming larger and raised.
Prevention and Aftercare for Scars
Sun Protection
Scar tissue is more prone to hyperpigmentation, so applying sunscreen with SPF 30 or higher can prevent scars from becoming darker and more visible.
Massage
Gently massaging a scar after the skin has fully healed can break down scar tissue and promote smoother healing.
Moisturiser
Keeping the scar hydrated with creams or ointments can prevent dryness and reduce the risk of raised or stiff scars.
