Can Scar Injection Treatments Help with Fibrotic Acne Scars? - Dermatology

Scar injection treatments, particularly for fibrotic acne scars, can be a topic of debate among dermatologists. Fibrotic scars, often referred to as hypertrophic or keloid scars, are characterized by an overproduction of collagen during the healing process, leading to raised and thickened areas of skin. These types of scars can be challenging to treat, and the effectiveness of various treatments can vary significantly from patient to patient.

Injectable treatments for scars typically include corticosteroids, which can help reduce inflammation and flatten raised scars. Other options may include fillers, which can temporarily improve the appearance of scars by adding volume, or more advanced treatments like platelet-rich plasma (PRP) injections, which aim to promote healing and collagen production. However, the term "scar injection" can sometimes be misleading, as not all injections are equally effective for every type of scar.

Regarding your experience with the dermatologist who dismissed the idea of scar injections, it's possible that they were expressing skepticism about the efficacy of such treatments for your specific type of scar. Some dermatologists may prefer to recommend more established methods, such as laser therapy, microneedling, or chemical peels, which have a more robust body of evidence supporting their effectiveness for acne scars. The response could also reflect a concern about the potential for unrealistic expectations regarding the outcomes of injection treatments.

As for the medications prescribed to you—Aczo gel (which contains azelaic acid), tretinoin cream, and doxycycline—each has its role in acne treatment and scar management:
1. Aczo Gel (Azelaic Acid): This topical medication is effective for treating acne and can help improve skin texture and tone. It has anti-inflammatory properties and can reduce post-inflammatory hyperpigmentation, which may help with the appearance of scars over time.

2. Tretinoin Cream: Tretinoin is a retinoid that promotes cell turnover and can improve skin texture and pigmentation. It is often used to treat acne and can also help with the appearance of scars by encouraging the growth of new skin cells and collagen production. Regular use can lead to gradual improvement in the appearance of scars.

3. Doxycycline: This antibiotic is typically prescribed for acne treatment to reduce bacterial growth and inflammation. While you mentioned not having active acne, doxycycline can still be beneficial in preventing future breakouts that could exacerbate scarring. However, if your primary concern is with existing scars and not active acne, you might want to discuss with your doctor whether this medication is necessary for your treatment plan.

In summary, while scar injection treatments can be beneficial for some individuals, their effectiveness can vary, and they may not be the first-line treatment for fibrotic acne scars. It's essential to have an open discussion with your dermatologist about your treatment options, including the potential benefits and limitations of each approach. If you're not seeing the results you desire, consider seeking a second opinion or exploring other treatment modalities that may be more effective for your specific type of scarring.
