Acne Scarring

Understanding Acne Scarring

Acne scarring is a common concern for individuals who have experienced severe or persistent acne. These scars can leave lasting marks on the skin, impacting self-esteem and overall confidence. Understanding the types of acne scarring and available treatment options is essential in addressing this issue effectively.

Types of Acne Scarring

  1. Atrophic Scars: Atrophic scars are depressions or indentations in the skin. They can be further categorised into:

    • Icepick Scars: Narrow, deep pits in the skin.

    • Boxcar Scars: Wider, box-shaped depressions with defined edges.

    • Rolling Scars: Wave-like undulations in the skin's surface.

  2. Hypertrophic and Keloid Scars: These scars are raised, firm, and can be darker in colour than the surrounding skin. They result from an overproduction of collagen during the healing process.

  3. Post-Inflammatory Hyperpigmentation (PIH) and Post-Inflammatory Erythema (PIE): While not true scars, PIH and PIE involve pigmented or red marks at the site of a healed acne blemish. This discolouration can persist long after the acne has resolved.

Treatment Options for Acne Scarring

  1. Topical Treatments: Dermatologists may recommend topical products containing ingredients like retinoids or vitamin C to promote collagen production and reduce the appearance of mild scars.

  2. Chemical Peels: Chemical peels involve the application of specialised solutions to the skin to remove the top layer, promoting new skin growth.

  3. Laser and Light Therapies: Various laser and light-based treatments, including vascular lasers, fractionated ablative and non-ablative lasers, can stimulate collagen production and improve the texture of the skin.

  4. Microneedling: Microneedling involves using tiny needles to create controlled micro-injuries in the skin, stimulating collagen and elastin production.

  5. TCA CROSS (Trichloroacetic Acid Chemical Reconstruction of Skin Scars): TCA CROSS is a specialised technique that uses trichloroacetic acid to treat pitted acne scars by promoting collagen production within the scar.

  6. Fillers: Dermal fillers, such as hyaluronic acid, can be used to elevate atrophic scars, often in combination with other techniques.

  7. Surgical Procedures: For more severe scarring, surgical interventions like punch excisions or subcision may be recommended to physically remove or release scar tissue.

  8. Keloid Scar Treatments: For raised scars, treatments like corticosteroid injections, often combined with 5-FU (5-fluorouracil) injections, can be effective in flattening and lightening the scars.

Consult with a dermatologist to determine the most appropriate treatment plan for your specific type of acne scarring. With the right approach, many individuals can significantly reduce the appearance of acne scars and enjoy smoother, clearer skin.
