Effectiveness of microneedle fractional radiofrequency combined with transcutaneous delivery of botulinum toxin in the management of post-acne scars.
Post-acne scars are a common sequela of acne, especially prevalent among young people. Delayed treatment not only affects self-perception of beauty but also affects the mental health of patients. This study aims to investigate the clinical efficacy of microneedle fractional radiofrequency (MFR) combined with botulinum toxin A (BoNT/A) in managing post-acne scars. This retrospective study involved 63 adult patients with post-acne scars, divided into two groups: group 1 (n = 30) and group 2 (n = 33). Group 1 received treatment with MFR combined with transcutaneous delivery of BoNT/A, whereas group 2 received treatment with MFR alone. The study observed the clinical outcomes in both groups. Based on experimental analysis, the combination of MFR with transcutaneous delivery of BoNT/A demonstrated superior clinical efficacy compared with group 2. There were no significant differences in baseline data or treatment-related pain and adverse reactions between the two groups. However, group 1 exhibited a higher effectiveness rate, lower ECCA score after treatment, higher satisfaction levels, and statistically significant differences compared to group 2. MFR combined with transcutaneous delivery of BoNT/A represents an effective and safe alternative for treating acne scars with minimal side effects and complications. Post-acne scars are a common sequela of acne and combination therapy proves beneficial. Microneedle fractional radiofrequency (MFR) combined with transcutaneous delivery of BoNT/A can be considered an effective and safe alternative for the treatment of acne scars with minimal side effects and complications. It works together through microneedles, radiofrequency, and botulinum toxin. MFR combined with transcutaneous delivery of BoNT/A is based on the direct action of MFR on acne scars and the use of microneedle to create a transient skin microchannel, facilitating BoNT/A penetration into the skin.

KGF-2 ameliorates UVB-triggered skin photodamage in mice by attenuating DNA damage and inflammatory response and mitochondrial dysfunction.
Long-term exposure to UVB induces DNA damage, inflammatory response, mitochondrial dysfunction, and apoptosis in skin cells, thus causing skin photodamage. Research has demonstrated the noteworthy antioxidant, anti-inflammatory, DNA repair, and mitochondrial protective properties of keratinocyte growth factor-2 (KGF-2). To examine the impact of KGF-2 on UVB-triggered skin photodamage in mice, hair-removed mice were initially exposed under UVB radiation and subsequently treated with KGF-2 hydrogel and repeated for 6 days. On day 7, the assessment of histopathological alterations, inflammation, DNA damage, mitochondrial function, and apoptosis in mouse skin was assessed. It was found that KGF-2 could effectively relieve cutaneous photodamage symptoms and inhibit epidermal proliferation in mice. Meanwhile, KGF-2 was found to significantly reduce DNA damage, attenuate the inflammatory response, and inhibit the mitochondria-mediated intrinsic apoptotic pathway in the UVB-exposed mouse skin photodamage model. To summarize, our results indicated that KGF-2 reduces the severity of mouse skin photodamage caused by UVB rays by attenuating DNA damage and the inflammatory response, besides inhibiting the mitochondria-mediated intrinsic apoptosis pathway.

Phototherapy for the treatment of cutaneous graft-versus-host disease: A systematic review.
Cutaneous graft-versus-host disease (GVHD) is a common complication of allogeneic hematopoietic stem cell transplantation. Phototherapy has been used to treat cutaneous GVHD, but data on its safety and efficacy are sparse. Review the current medical literature regarding the efficacy, dosing, and safety of various types of phototherapies for the treatment of cutaneous GVHD. A systematic review of PubMed, Embase, Cochrane, and ClinicalTrials databases was performed. Publications were screened according to the PRISMA guidelines. Exclusion criteria comprised case reports and case series reporting less than five patients, review articles, and articles not published in English. A total of 28/1304 (2.5%) studies were included. Fifteen studies (n = 267 patients) focused on psoralen and ultraviolet (UV) A (PUVA), in which 65.5% of patients received concomitantly other systemic treatments. The response rate was 89.9%, with a mean of 33.2 treatments. Adverse events were recorded in 54% but were mainly mild. Eight studies, encompassing 95 patients, focused on narrow-band (NB) UVB. A response was observed in 94%, with a mean number of 26 treatments and 8.6% adverse effects. UVA1 was reported in six studies (n = 132 patients). A response was recorded in 89.3% with a mean of 26.2 treatments. Adverse events were noted in 70.1%, with a discontinuation rate of 10.9%. It should be noted that adverse events were recorded during the follow-up period of the studies, which varied significantly, ranging from no follow-up to 31 months. Current data regarding the use of phototherapy for the treatment of cutaneous GVHD are based on retrospective studies and case series. The present report advocates the use of one of the three modalities of phototherapy as an effective and safe adjunctive treatment for cutaneous GVHD, especially NB UVB phototherapy.

Skin microbiome profiling reveals the crucial role of microbial metabolites in anti-photoaging.
Skin microbiota is essential for health maintenance. Photoaging is the primary environmental factor that affects skin homeostasis, but whether it influences the skin microbiota remains unclear. The objective of this study is to investigate the relationship between photoaging and skin microbiome. A cohort of senior bus drivers was considered as a long-term unilateral ultraviolet (UV) irradiated population. 16S rRNA amplicon sequencing was conducted to assess skin microbial composition variations on different sides of their faces. The microbiome characteristics of the photoaged population were further examined by photoaging guinea pig models, and the correlations between microbial metabolites and aging-related cytokines were analyzed by high-throughput sequencing and reverse transcription polymerase chain reaction. Photoaging decreased the relative abundance of microorganisms including Georgenia and Thermobifida in human skin and downregulated the generation of skin microbe-derived antioxidative metabolites such as ectoin. In animal models, Lactobacillus and Streptobacillus abundance in both the epidermis and dermis dropped after UV irradiation, resulting in low levels of skin antioxidative molecules and leading to elevated expressions of the collagen degradation factors matrix metalloproteinase (MMP)-1 and MMP-2 and inflammatory factors such as interleukin (IL)-1β and IL-6. Skin microbial characteristics have an impact in photoaging and the loss of microbe-derived antioxidative metabolites impairs skin cells and accelerates the aging process. Therefore, microbiome-based therapeutics may have potential in delaying skin aging.

Carcinogenic risk in patients treated with UVA-1 phototherapy: A 5-year retrospective study.
UVA-1 phototherapy was first used to treat atopic dermatitis and afterwards to several other skin diseases. The contribution of UVA-1 in human photocarcinogenesis, skin photoaging, immune suppression, and hyperpigmentation is now well established. The actual contribution of UVA-1 radiation to the development of malignant melanoma (MM) in humans cannot be excluded. The aim of the study is to evaluate the risk of developing skin cancers (non-melanoma skin cancers (NMSCs) and MM) in patients treated with UVA-1 phototherapy with a 5-year dermatological follow-up. We conducted a retrospective cohort study with 31 patients with morphea and atopic dermatitis treated with medium dose UVA-1 phototherapy (34 J/cm2). All enrolled patients underwent an oncologic prevention visit annually with a 5-year follow-up with clinical evaluation of the entire skin surface. During the 5-year follow-up, we recorded a case of basal cell carcinoma (BCC) in the cervical region and one case of MM on the back (pT1a). In both cases, the patients were female and affected by morphea. The Glogau 3 group is prevalent (42%), which is consistent with moderate to severe aging; the data appear to be compatible with the age. This study attests that medium-dose UVA-1 phototherapy does not increase the risk of developing skin tumors and that UVA-1 phototherapy is not a worsening factor of facial photoaging. The main limitation of the study is the small sample size, avoiding to obtain statistically significant values. It was not possible to analyze individually the actual daily sun exposure during the 5-year observation period and to correlate it in terms of time and tumor development. Further studies with large sample sizes will be needed to confirm our data. Our study reaffirms how the dermatological examination performed annually is essential in the follow-up of patients undergoing this type of therapy.
