Objective: To analyze the dermal collagen of 15 postmenopausal women who had being treated with systemic estrogen replacement before and after using topical a 0.01% estrogen treatment.
Methods: Fifteen patients were included in this clinical trial using the systemic estrogen therapy for at least 1 year (minimum and maximum lengths of therapy were 13 and 40 months, respectively). A facial punch was performed in the preauricular area for collecting samples before and after the 16 weeks of treatment. Blood samples were also collected for estradiol level determination. The morphometric determination of epithelial and dermal thickness as well as dermal collagen were measured using a suitable software. The paired Student's t-test was used for statistical analysis.
Results: The epithelial and dermal thickness enhanced after the topic estrogen therapy (P<0.01). The amount of collagen significantly increased after 16 weeks of treatment (P<0.001). The estrogen levels did not significant increase after the topical therapy (P > or = 0.05).
Conclusion: Our data suggested that topical estrogen associated to systemic estrogen therapy seems to increase the expression of skin collagen amount, which may prove to be beneficial for the postmenopausal facial skin.

Introduction: The human skin acts as a protective barrier against external pathogens and hosts a diverse microbiome consisting of bacteria, fungi, viruses, and archaea. Disruptions to the skin microbiome can impact immune function, leading to inflammatory and autoimmune conditions. The importance of pH for the microbiome is paramount.

Unlabelled: This study examined how isoflavone interventions impact bone health in postmenopausal women. Analyzing 73 trials found that isoflavones reduce bone resorption markers, enhance bone minerals, and increase hormones regulating bone metabolism. This suggests that isoflavones could help address bone health issues in postmenopausal women.

Rheumatoid arthritis (RA) can cause blood pressure (BP) elevation in estrogen-deficient, post-menopausal women; however, the underlying mechanisms are not well understood. In this study, the aortic involvement and its underlying mechanisms that contribute to the BP elevation in estrogen-deficient, RA condition were identified. Ovariectomy was performed to create a state of estrogen deficiency and RA was then induced in ovariectomized rats by using incomplete Freund's adjuvant and immune-mediated collagen type-II.

Background: Zhuanggu Shubi ointment (ZGSBG) has good efficacy in postmenopausal osteoporosis (PMO), but the mechanism of efficacy involving gut microecology has not been elucidated.
Objective: This study investigated the mechanism of ZGSBG in regulating gut microecology in PMO.
Methods: The bilateral ovarian denervation method was used to construct a rat model of PMO and was administered ZGSBG.

Background: The dermal extracellular matrix (ECM) is a dynamic scaffold composed mainly of proteins, with collagen as the key structural component providing resilience and support to the skin. Post-menopause, declining estrogen levels lead to a significant reduction in skin health, notably a 30% decrease in collagen types I and III within 5 years.
Aim: To discover natural extracts that stimulate collagen production.
