Acne is one of the most common skin disorders, and its occurrence is closely related to many factors, including sebum secretion, hormone levels, bacterial infection, and inflammatory reactions. Among these, changes in sebum secretion are believed to be one important factor of acne. Increased sebum secretion can induce acne occurrence, and increasing evidence indicates sebum component changes are also strongly related to acne occurrence. Recently, developments in lipidomics have provided effective lipid analysis methods. These can help elucidate the effects of different types of sebum on acne occurrence and provide a theoretical basis for research on the mechanisms of acne pathogenesis and treatment.

Human Dermatology Clinic, Incheon, Republic of Korea.
Background: Intradermal injection of CPM-HA20G, a low-viscoelasticity hyaluronic acid (HA) dermal filler with glycerol, has been shown to be effective for facial rejuvenation in Caucasians, but research in Asians is limited.
Aims: This study aimed to evaluate the effectiveness and safety of CPM-HA20G in enhancing facial skin quality in Korean women using a protocol developed by local aesthetic experts.
Patients/methods: In this 24-week prospective, single-arm, open-label study, 20 women received CPM-HA20G injections in the immediate subdermal layer on the anterior cheek (1 mL per side; total 2 mL) in three sessions every 4 weeks.

Cosmetic Research Center, School of Chemical and Material Engineering, Jiangnan University, Wuxi, China.
Background: Excessive lipogenesis of the skin triggers some dermatological concerns, such as enlarged pores, acne, and blackheads. Although topical drug treatments can offer temporary relief, their prolonged usage may lead to side effects of dryness, irritation, or allergic reactions. Consequently, the development of safer and efficacious ingredients in cosmetics for managing sebum overproduction represents a significant yet challenging endeavor.

Article Synopsis
- The study examines the relationship between skin oxylipins, which are bioactive lipids produced from fatty acids by skin microbes, and different microbial communities on the skin of children and adults.
- Findings highlighted that Malassezia restricta, a type of skin fungus, has a positive impact on the production of a specific oxylipin (9,10-DiHOME) in adults, while showing a negative correlation with its precursor in children, indicating differences in skin chemistry across age groups.
- The research suggests a complex communication system between skin microbes and host lipid metabolism that could have implications for skin health, emphasizing the need for further exploration of these interactions for potential therapeutic applications.
