Microneedling's Efficacy When Treating Acne Scars
Acne is a common skin condition affecting millions of people worldwide. While the breakouts can be challenging, the lingering scars can be even more difficult to treat. Individuals with acne scars often experience a decline in self-confidence and overall well-being. Thankfully, scientific innovations can help improve the appearance of these issues, microneedling being one of the best options. In this article, we’ll look into the efficacy of microneedling acne scars by exploring the latest research and reviewing how this technology can transform the appearance of scarred skin.
How Effective is Microneedling in Treating Acne Scars?
Microneedling is a skin rejuvenation procedure that has gained significant attention because of its numerous benefits, including having a good safety profile and minimal downtime. Fine and sterile needles create precise, intentional micro-injuries on the epidermis, activating the body’s natural healing response.
Several studies have demonstrated microneedling’s effectiveness for acne scars, as a monotherapy or in combination. Here’s a review of some of the research reviewing the efficacy of microneedling for ice pick scaring:
A Review of the Randomized Controlled Trials of Microneedling (Sitohang et al., 2021)
In this systematic review, researchers dissected the results of 9 RCTs performed to measure acne scar microneedling results. Despite not having a specific protocol due to a lack of standardized treatment regimens, the included studies consistently demonstrated that microneedling effectively treats acne scars and is well-tolerated.
Combination of Microneedling and Chemical Reconstruction of Scarred Skin Therapy (CROSS) (Lopez, 2024)
In this study, a five-year combination treatment using microneedling and CROSS on patients with acne scars having Fitzpatrick skin types III to V (medium to dark brown skin) was done. The patients exhibited Significant and quantifiable improvements, with many showing Grade 1 and Grade 2 improvements in both the Global Aesthetic Improvement Scale and Goodman and Baron Qualitative scar grading system.
Subcision, Microneedling, and 15% Trichloroacetic Acid (TCA) Peel (Garg & Baveja, 2014)
This study observed significant improvements using Goodman and Baron Qualitative grading (e.g., severe or Grade 4 scars improving to Grade 2 or Grade 3 scars) and reported high patient satisfaction. This was after the patients received 6 sessions each of Subcision, microneedling, and 15% trichloroacetic acid (TCA) Peel with two weeks between each.
How Microneedling Works
The mechanism of action behind the effectiveness of microneedling is multifaceted. The controlled micro-injuries created by the needles remodel the skin, reducing the appearance of acne scars and improving overall skin texture and tone.
● Collagen Induction: The micro-injuries can stimulate the production of new collagen fibers, which help build volume and smooth out the appearance of acne scars.
● Neovascularization: Microneedling possibly promotes the formation of new blood vessels, which improves blood flow and nutrient delivery to the treated area, further enhancing the skin’s healing and rejuvenation.
● Transdermal Delivery: When applied after the procedure, the microchannels created by the needles can improve the absorption and efficacy of topical treatments, such as serums or other scar-reducing compounds.
Setting Your Patients' Expectations: Are Microneedling Results Permanent?
While microneedling can produce significant and long-lasting improvements in the appearance of acne scars, the results are not necessarily permanent because the skin is constantly undergoing a natural aging process, which can cause new scars to form or existing scars to become more pronounced over time. Factors such as sun exposure, lifestyle, and overall skin health can also influence the longevity of the results. Microneedling benefits can be maintained if patients establish a comprehensive skincare regimen and schedule regular touch-up treatments. Most experts recommend a series of 3-6 microneedling sessions, spaced 4-6 weeks apart, to achieve optimal results (although this can vary based on the severity of the case). After that, periodic maintenance treatments may be necessary to ensure the continued improvement and maintenance of acne scar appearance.
