Acne Scars: Causes and Treatment Options - Dermatology

More Info

---

Acne scars are a common concern for many individuals who have experienced acne, particularly inflammatory types. The hard texture you feel beneath the skin after the acne has healed is often due to a process called "post-inflammatory hyperplasia" or "post-inflammatory erythema," which can lead to the formation of scar tissue. This condition can occur when the skin undergoes inflammation, leading to an overproduction of collagen or a disruption in the normal healing process.


Causes of Acne Scars
1. Inflammation: When acne lesions become inflamed, the body responds by sending immune cells to the area. This inflammation can damage the surrounding skin tissue, leading to scarring.


2. Collagen Production: The skin produces collagen to heal wounds. In some cases, too much collagen is produced, resulting in raised scars (hypertrophic scars or keloids), while in other cases, insufficient collagen leads to depressed scars (atrophic scars).

3. Skin Type: Individuals with darker skin tones may be more prone to hyperpigmentation and scarring due to the increased melanin production in response to inflammation.

4. Picking or Squeezing: Manipulating acne lesions can exacerbate inflammation and increase the risk of scarring.


Treatment Options
There are several treatment options available for managing acne scars, and the choice of treatment often depends on the type and severity of the scars:
1. Topical Treatments: Products containing retinoids, alpha hydroxy acids (AHAs), or beta hydroxy acids (BHAs) can help improve skin texture and promote cell turnover, which may reduce the appearance of scars over time.

2. Chemical Peels: These treatments involve applying a chemical solution to exfoliate the top layers of skin, promoting new skin growth and reducing the appearance of scars.

3. Microneedling: This procedure involves using fine needles to create micro-injuries in the skin, stimulating collagen production and improving skin texture.

4. Laser Therapy: Laser treatments can target specific layers of skin to either resurface the skin or stimulate collagen production, helping to reduce the appearance of scars.

5. Injectable Treatments: Softening agents such as hyaluronic acid fillers can be injected into depressed scars to raise them to the level of surrounding skin. Additionally, corticosteroid injections can help flatten raised scars.

6. Subcision: This is a minor surgical procedure where a needle is inserted under the skin to break up fibrous bands that tether the scar to the underlying tissue, allowing the skin to lift and flatten.


Injectable Softening Agents
Regarding your inquiry about injectable softening agents, yes, there are treatments available that can help soften and improve the appearance of scars. Hyaluronic acid fillers are commonly used for this purpose. They can provide immediate results by filling in depressed areas and creating a smoother skin surface. Additionally, corticosteroid injections can be used for raised scars to help flatten them.


Conclusion
The hard texture you are experiencing is likely related to the healing process of your skin following inflammation from acne. While it can be frustrating, there are various treatment options available that can help improve the appearance of your scars. It is essential to consult with a dermatologist who can assess your specific situation and recommend the most appropriate treatment plan tailored to your needs. Remember, patience is key, as scar treatments often require multiple sessions and time to see significant improvement.
