Which term refers to a thick scar resulting from excessive growth of fibrous tissue?

1. Blackhead

2. Scar

3. Keloid

4. Comedo

The correct answer is: Keloid

The term that refers to a thick scar resulting from excessive growth of fibrous tissue is keloid. Keloids are raised scars that extend beyond the original injury site due to an overproduction of collagen during the healing process. This overgrowth of tissue can result in scarring that is often larger than the wound itself and may vary in color, sometimes appearing darker than the surrounding skin. Understanding keloids is important in esthetics, as these types of scars can affect a client's skin appearance and may influence treatment options. For instance, clients may be concerned about the cosmetic impact of keloids, and estheticians may need to provide guidance on options for management or to advise against certain procedures that could worsen scar formation. The other terms mentioned refer to different conditions. A blackhead and comedo both describe clogged hair follicles in the skin, commonly associated with acne. While a scar does refer to the result of skin healing after injury, it does not specifically indicate the thick, raised nature associated with keloids.
