Acne scarring is a common side effects of acne breakouts which occurs as a result of damage to the skin during the healing of active acne. A scar is the body's response to healing the wound, in which the skin cells combine with the connective tissue, and cell multiplication takes place to repair the damage. Acne scars also develop because of the post-inflammatory hyperpigmentation and form red, black, and brown discolouration of the affected skin surface. Some scars may resolve on their own, but mostly these disfiguring marks do not resolve without treatment.
Types of Acne Scars
There are two types of acne scars depending upon there whether there is a net gain or loss of collagen.
1. Atrophic scars: These scars develop when there is loss of tissue, and when enough fibroblast or connective tissue is not made during the healing period. These scars appear like small depressions in the skin. These are further divided into:
1.1. Icepick: These types of scars are deep, narrow, sharp, and vertically extend deep in the dermis or subcutaneous tissue.
1.2 Boxcar: These types of scars have oval to round depressions and have vertical edges that are sharply demarcated.
1.3 Rolling scar: They appear as sunken or wavy areas on the affected area, and lack sharp borders. These are formed when a fibrous band of tissue develops between the skin and subcutaneous tissue.
2. Hypertrophic and keloid scars: These types of scars are typically pink and raised in appearance. These are produced due to excess collagen production and deposition with decreased collagenase activity.
These occur in the original site of injury that contains thick hyalinized collagen bundles. Keloids occur in the form of reddish-purple nodules and papules, and it often grows beyond the border of the original wound.
Dermabrasion facial resurfacing technique, removes the epidermis and penetrates at the level of the reticular dermis. It promotes remodelling of the skin’s structural proteins. Microdermabrasion process accelerates the natural process of exfoliation, by removing the outer layer of the epidermis. These techniques improve the skin texture and also effectively treats acne scars.
The best way to get rid of acne scars is to avoid them in the first place and taking proper precautions and treatments for treating acne-prone skin.
