From the Guidelines

Severe acne scarring is primarily associated with inflammatory acne, delayed or inadequate treatment, genetic predisposition, and manipulation of acne lesions, and early intervention with appropriate treatments like topical retinoids, antibiotics, or isotretinoin for severe cases can significantly reduce scarring risk by controlling inflammation before permanent damage occurs.

Factors Associated with Severe Acne Scarring

The main factors associated with more severe acne scarring include:

  • Inflammatory acne, particularly nodular or cystic acne, which damages the dermis and increases the risk of scarring 1
  • Delayed or inadequate treatment, allowing inflammation to persist and increasing tissue damage and subsequent scarring 1
  • Genetic predisposition, with some individuals having a hereditary tendency toward abnormal scarring responses, including keloid or hypertrophic scar formation 1
  • Manipulation of acne lesions, such as picking, squeezing, or popping pimples, which forces bacteria deeper into the skin and causes additional trauma, increasing scarring risk 1 Other contributing factors include hormonal fluctuations that worsen inflammatory acne, certain medications like corticosteroids that can affect skin healing, and environmental factors such as excessive sun exposure that can worsen the appearance of existing scars 1.

Importance of Early Intervention

Early intervention with appropriate treatments is crucial in reducing scarring risk. Topical retinoids, antibiotics, and isotretinoin are effective treatments for severe acne, and their use can significantly reduce scarring risk by controlling inflammation before permanent damage occurs 1.

Treatment Options

Treatment options for severe acne include:

  • Topical retinoids, which are vitamin A derivatives and serve as the cornerstone of acne treatment 1
  • Antibiotics, which can be used topically or orally to reduce inflammation and prevent scarring 1
  • Isotretinoin, which is a strong recommendation for severe acne, acne causing psychosocial burden or scarring, or acne failing standard treatment with oral or topical therapy 1 By understanding the factors associated with severe acne scarring and using appropriate treatments early, individuals can reduce their risk of scarring and achieve better treatment outcomes.

From the Research

Factors Associated with Acne Scarring

The main factors associated with more severe acne (acne vulgaris) scarring include:

  • Severity of inflammatory nodulocystic acne 2
  • Duration of inflammation 2, 3
  • Self-manipulation of acne lesions 2
  • Delayed treatment of acne, allowing inflammation to persist 2, 3

Types of Acne Scars

There are two general types of acne scars:

  • Hypertrophic (keloid) scars 2
  • Atrophic (icepick, rolling, and boxcar) scars 2

Prevention of Acne Scarring

The best method of preventing or limiting scarring is to treat acne early enough to minimize the extent and duration of inflammation 2, 3 Early initiation of therapy is directly proportional to effective therapeutic outcomes and prevents complications 3
