Microneedling depth impacts scarsEvaluation of microneedling depth of penetration in management of atrophic acne scars: a split-face comparative study.
In our exploration of treating atrophic acne scars, we focused on the effects of different microneedling depths using Dermapen. We designed a split-face study involving 14 individuals, where each side of their face received a different treatment depth over six sessions, spaced two weeks apart.
On one side, the needles penetrated 2.5 mm into the skin, while the other side used 1.5 mm. We observed a noticeable difference in the improvement of scars, with the deeper 2.5 mm treatment showing significantly better results both clinically and at a cellular level.
The findings suggest that deeper microneedling might foster better collagen induction, which is crucial for skin repair. Both treatments improved collagen and elastin fibers, but the more profound impact from the deeper needles highlights how penetration depth might be a key factor in achieving effective results in scar management.

Effective collagen treatments for scarsEfficacy of Polycaprolactone Threads in Treating Atrophic Acne Scars: A Split-face Comparative Study.
We set out to explore the effectiveness of collagen treatment for atrophic acne scars using two different approaches: polycaprolactone (PCL) threads and microneedling combined with platelet-rich plasma (PRP). In our research, 24 patients participated in a split-face study where one side of the face was treated with PCL threads, and the other side underwent microneedling with PRP. Each participant received four sessions of microneedling on one side, while the other side was treated with just one session of threads.
After monitoring the patients for six months, we observed a significant improvement in skin texture and scar appearance. Specifically, 95.8% of patients noted progress on the side treated with threads compared to 83.3% on the microneedling side. Additionally, satisfaction ratings were notably higher among those who received the thread treatment.
Both procedures were associated with mild side effects, like transient swelling and redness, which cleared up quickly. Our findings suggest that PCL threads could be a promising collagen-boosting alternative for treating acne scars, providing effective results with minimal discomfort.

Hyaluronic acid shows significant scar improvementDual-Plane Treatment With Highly Concentrated Hybrid Cooperative Complexes of Hyaluronans for Facial Atrophic Acne Scars.
We explored the effectiveness of a high-concentration (4.5%) hyaluronic acid filler designed to treat facial acne scars. Participants received two treatments, and we evaluated improvements after four months.
Notably, patients experienced a 12% improvement in scar severity shortly after treatment and a significant 31% improvement after four months. The skin's depth measurement also showed a 20% reduction in acne scar deepness with no serious side effects reported.
These promising results suggest that this hyaluronic acid formulation could be a valuable option for individuals seeking to improve their acne scarring.

Promising treatment for acne scarsClinical evaluation of needle-free electronic pneumatic hyaluronic acid injection treatment for facial atrophic acne scars: A prospective, randomized comparative trial.
We examined how needle-free electronic pneumatic injections of hyaluronic acid could treat facial acne scars. In a carefully designed study, thirty Japanese participants received treatments on one side of their face, with follow-ups conducted for three months after completing three sessions.
Remarkably, 48.3% of the treated sides showed significant improvement, while none of the untreated sides did. Participants reported high satisfaction rates and the results were confirmed by imaging analysis. Overall, this treatment demonstrated promising effects on rolling acne scars with minimal side effects.

Hyaluronic acid shows scar improvementA combined subcision approach with either fractional CO laser (10,600 nm) or cross-linked hyaluronic acid versus subcision alone in atrophic post-acne scar treatment.
This study explored the effectiveness of using hyaluronic acid filler alongside subcision for treating post-acne scars.
In a controlled trial with 40 participants, we observed that both the subcision combined with hyaluronic acid and with fractional CO laser treatments showed significant improvements.
However, when comparing the two enhanced methods, neither was found to be statistically better than the other. Importantly, subcision alone still provided some improvement, even if modest. Overall, combining these treatments appears beneficial without serious side effects.
