Microneedling For Acne Scars!


Some of you may be familiar with the microneedling tool already. Maybe you've looked into using it, or you've seen me post about it in the past and what it can do for your acne scarring (or any scarring, for that matter).

Post-acne scarring is disfiguring, both physically & psychologically. Over the past two decades, multiple modalities for treatment of acne scars have emerged. The latest in the treatment armamentarium is microneedling. Microneedling therapy, also known as percutaneous collagen induction therapy, is a simple, inexpensive procedure with no downtime. The needles cause small pinpoint injuries on the skin, which heal within two to three days with no post-treatment sequelae. Micronedling remolds the skin by creating thousands of microscopic channels through the skin, increasing the formation of new tissue by activating the body’s wound healing cascade (hemostasis-inflammation-proliferation-tissue remodeling). The micro-channeling causes the release of growth factors that promote scar-less healing and the deposition of normal woven collagen rather than scar collagen. The fibroblasts are responsible for collagen production. After rolling, you also create micro channels to let serums absorb deep into the skin instead of having your serum just sit on the top of your skin. This is great for a serum that also helps target scarring, as it can allow the scar-healing ingredients to penetrate deeper and more effectively.

In one study there was significant improvement in superficial & moderately deep scars (grade 1-3). There was also improvement in skin texture, & reduction in postacne pigmentation. In another study, there was a statistically significant decrease in mean acne scar assessment score from 11.73 ± 3.12 at baseline to 6.5 ± 2.71 after five sittings with a microneedling tool. Investigators' assessments based on photographic evaluation showed a 50-75% improvement in the majority of patients. The results on visual analog scale (VAS) analysis showed "good response" in 22 patients & "excellent response" in four patients, at the end of study. In a third study, Goodman & Baron's Global Acne Scarring System showed that by qualitative assessment of 31 patients with grade 3 & grade 4 acne scars, 80.64% showed improvement by 2 grades & 19.35% showed improvement by 1 grade. In yet another study, 26 out of 36 patients (72.2%) showed an excellent response to microneedling treatment while 6 others achieved a good response (16.7%). In one study, twenty blinded biopsies taken from 10 different patients from various parts of their body demonstrated an average increase in new fibers of 206%, in one biopsy a 1000% increase was recorded.

Thus, microneedling therapy is a viable avenue for scar reduction, with less adverse side effects than more invasive therapies like laser therapy. In conjunction with a treatment serum, microneedling is made even more effective. Microneedling is a simple & cheap means of treatment modality for acne scars remodulation with little downtime, & satisfactory results.
