Acne is an inflammatory skin disease mainly caused by , which can cause local inflammatory reactions and develop into chronic inflammatory diseases in severe cases. To avoid the use of antibiotics and to effectively treat the site of acne, we report a sodium hyaluronate microneedle patch that mediates the transdermal delivery of ultrasound-responsive nanoparticles for the effective treatment of acne. The patch contains nanoparticles formed by zinc porphyrin-based metal-organic framework and zinc oxide (ZnTCPP@ZnO). We demonstrated activated oxygen-mediated killing of with an antibacterial efficiency of 99.73% under 15 min of ultrasound irradiation, resulting in a decrease in levels of acne-related factors, including tumor necrosis factor-α, interleukins, and matrix metalloproteinases. The zinc ions up-regulated DNA replication-related genes, promoting the proliferation of fibroblasts and, consequently, skin repair. This research leads to a highly effective strategy for acne treatment through the interface engineering of ultrasound response.

Background: Photodynamic therapy (PDT) is beneficial for managing rosacea, and chlorin e6 derivative-mediated photodynamic therapy (STBF-PDT) has demonstrated efficacy in reducing acne lesions with mild adverse reactions.
Objectives: This study aimed to assess the effectiveness and safety of STBF-PDT for the treatment of moderate-to-severe rosacea.
Methods: In this prospective, randomised, evaluator-blind controlled study, patients with moderate-to-severe rosacea were assigned to receive up to six STBF-PDT sessions or 100 mg of doxycycline daily for eight weeks, followed by a 24-week follow-up.

Acne and acne sequelae can have an important impact on patients' quality of life, affecting interpersonal relationships and social functioning. Acne-induced scars (AIS) and acne-induced macular hyperpigmentation (AIH), in particular, are a major concern for patients with acne, as their management is challenging and often unsatisfactory. Retinoids are considered the mainstay of acne treatment because of their action on multiple pathogenetic factors, and there is increasing evidence that they can also improve AIS and AIH.

Fractional radiofrequency microneedling (FRM) is a popular, minimally invasive skin rejuvenation modality for treating acne scarring. In this study, we aimed to systematically evaluate the current literature on the efficacy and safety of FRM as a monotherapy to treat different types of facial acne scarring. We systematically reviewed all available literature on FRM techniques used for acne scarring by searching the PubMed and EBSCO databases up to July 2024.
