Afzelin reduces acne inflammationEffect of afzelin on inflammation and lipogenesis in particulate matter-stimulated treated SZ95 sebocytes.
Study highlights protein's limited impact
We focused on exploring how afzelin, a natural flavonoid known for its anti-inflammatory effects, influences acne-related inflammation and sebum production in a specific type of skin cell called SZ95 sebocytes. To set the stage for our investigation, we simulated an acne-like condition by introducing heat-killed bacteria into the cells, along with exposure to particulate matter (PM).
We observed that PM may worsen acne by increasing inflammatory responses and promoting sebum secretion. Excitingly, when we treated these cells with afzelin, we found that it significantly reduced the inflammatory cytokine levels and inhibited the processes that lead to excess oil production. This suggests that afzelin could serve as a beneficial treatment option for alleviating PM-related acne.
Overall, our findings highlight the dual role of afzelin in combating acne by addressing both inflammation and sebum overproduction, positioning it as a potential therapeutic agent in skincare treatments.

We investigated the impact of two peptides, RL-QN15 and OH-CATH30, on treating acne in mice. Our findings revealed that when applied together, these peptides significantly reduced the growth of Propionibacterium acnes, the bacteria responsible for acne, and decreased the associated swelling.
Alongside tackling the bacteria, this combination also helped lower the production of inflammatory molecules, such as IL-1β and TNF-α, which are known to worsen acne condition. Notably, the treatment encouraged collagen production, promoting better skin repair and healing.
From a biological standpoint, we learned that RL-QN15 and OH-CATH30 work by suppressing the toll-like receptor 2 (TLR2) and the NF-κB signaling pathway, which ultimately reduces inflammation and aids in skin recovery. This points to their potential as a promising strategy for acne therapy, emphasizing the importance of looking at innovative protein combinations.
Overall, our study highlights a new, effective approach in tackling the persistent issue of acne. By focusing on these combined proteins, we are paving the way for advanced treatment options that could significantly improve the quality of life for those suffering from this common skin condition.

Promising peptides for acne treatmentNovel-designed antimicrobial peptides with dual antimicrobial and anti-inflammatory actions against Cutibacterium acnes for acne vulgaris therapy.
High relevance to acne treatment
We explored the potential of novel antimicrobial peptides (AMPs) designed to combat acne vulgaris, a common skin issue caused by the bacteria Cutibacterium acnes. Traditional treatments often lead to antibiotic resistance and unwanted side effects, prompting the need for alternative solutions.
Our approach involved creating short peptides made up of 13 amino acids. We specifically tweaked these peptides by adjusting the number and position of tryptophan residues to enhance their effectiveness. Among the various peptides synthesized, we found that DAP-7 and DAP-10 stood out for their strong antimicrobial properties against both antibiotic-sensitive and -resistant strains of C. acnes, while causing minimal damage to human cells.
By targeting the bacterial membrane, these peptides can disrupt the bacteria, leading to their breakdown. Additionally, DAP-7 and DAP-10 were effective in reducing the levels of inflammation linked to acne. Remarkably, DAP-7 resulted not only in fewer C. acnes colonies but also significantly decreased swelling in a mouse model of acne.
Our findings indicate that DAP-7 and DAP-10 are promising options for developing new acne treatments, offering a dual action that tackles both the bacteria and the associated inflammation.

Microneedling depth impacts scarsEvaluation of microneedling depth of penetration in management of atrophic acne scars: a split-face comparative study.
Moderate relevance to collagen treatment
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.

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.
