The issue of indentations caused by acne injections?


Hello, doctor.
Two months ago, I received two acne injections in the same area, and I later noticed a significant indentation that is larger than the original acne.
This has caused me a lot of concern.
Although I found online that it may take 3-6 months for it to potentially recover, I would like to ask if there is really a chance for it to gradually return to its original state? Thank you, doctor!

Hello: The indentation from acne injections may require a few months of observation to see if the skin can return to a smooth state.
If the acne was severely inflamed prior, it could also lead to atrophic scars.
If the indentations are still very noticeable after six months, it is advisable to consult a dermatologist for diagnosis and treatment.
Thank you!

More Info


When it comes to indentations or depressions in the skin following acne injections, it is important to understand the underlying mechanisms and the potential for recovery. Acne injections, often involving corticosteroids or other substances, can lead to localized skin changes, including atrophy or indentations, particularly if the injections are repeated in the same area.

The formation of indentations can occur due to several factors. First, the injection itself can cause localized trauma to the skin, leading to inflammation and subsequent tissue remodeling. If the injected substance causes a significant inflammatory response, it may result in the loss of collagen and elastin in the area, leading to a depressed appearance. Additionally, repeated injections can exacerbate this effect, especially if the skin is sensitive or if the technique used is not optimal.

In terms of recovery, it is true that many skin changes can improve over time. The skin has a remarkable ability to heal and regenerate, and in many cases, indentations may gradually fill in as the body produces new collagen and elastin. The timeframe for this recovery can vary widely among individuals, typically ranging from a few months to over a year. Factors influencing recovery include the individual's skin type, age, overall health, and the specific characteristics of the indentation.

While waiting for natural recovery, there are several options to consider that may help improve the appearance of the skin. These include:
1. Topical Treatments: Products containing retinoids, hyaluronic acid, or peptides can promote skin renewal and improve texture. They may help stimulate collagen production and enhance skin elasticity.

2. Microneedling: This procedure involves using fine needles to create micro-injuries in the skin, which can stimulate collagen production and improve the appearance of indentations.

3. Dermal Fillers: In some cases, dermatologists may recommend using fillers to temporarily plump up the area and reduce the appearance of indentations. This is a more immediate solution but does not address the underlying issue.

4. Laser Treatments: Certain laser therapies can help improve skin texture and stimulate collagen production, potentially reducing the appearance of indentations over time.

5. Chemical Peels: These can help exfoliate the top layer of skin and promote new skin growth, which may improve the overall appearance of the affected area.

It is essential to consult with a qualified dermatologist or skincare professional who can assess your specific situation and recommend the most appropriate treatment options. They can also provide guidance on what to expect in terms of recovery and improvement.

In summary, while indentations after acne injections can be concerning, there is potential for recovery over time. The skin's natural healing processes, combined with appropriate treatments, can lead to improvements. However, it is crucial to manage expectations and seek professional advice for the best outcomes.
