Abstract
Background Water exposed to a magnetic field exhibits several changes in its properties, such as increased electrical conductivity, reduced density, and low surface tension. Additionally, it has reduced dissolved oxygen levels and becomes more alkaline. Previous experimental studies have demonstrated that exposure to saline alkaline water leads to a dose-dependent increase in the expression of autophagy-related genes. Here, we hypothesize that the topical application of magnetized alkaline water to the skin can activate autophagy and improve cutaneous biophysical parameters, making it a promising strategy for enhancing skin aesthetics. Methods Two distinct substudies were undertaken. Firstly, a 12-week, uncontrolled, open-label investigation was conducted with 20 females who desired to enhance the appearance of their facial and neck skin. Secondly, a molecular study was carried out on a subset of 10 females to investigate the serum's impact on two autophagy markers (Beclin-1 and mammalian/mechanistic target of rapamycin {mTOR}) in skin biopsies taken from the posterior neck area below the hair attachment line. Results After a period of 12 weeks, the application of the serum resulted in significant improvements in skin hydration within the stratum corneum (56 ± 14 arbitrary units {a.u.}) compared to the baseline measurement (47 ± 12 a.u.; p < 0.001). Moreover, the transepidermal water loss (TEWL) decreased from 14 ± 2 g/m2/hour to 11 ± 3 g/m2/hour (p < 0.001). The results also revealed a notable reduction in sebum content from 38 ± 7 µg/cm2 to 30 ± 4 µg/cm2 after the 12-week period of serum application (<0.001). Additionally, the melanin index (p < 0.01) and erythema index (p < 0.001) were both significantly lower at 12 weeks compared to baseline. The molecular study showed a 38% increase in Beclin-1 levels after 12 weeks of serum application on the posterior neck area, as measured from skin biopsies. In contrast, mTOR levels decreased by 24% from baseline to 12 weeks. Conclusion The application of magnetized saline water topically, within a serum formulation, shows potential in improving skin biophysical parameters for females seeking to enhance the appearance of their facial and neck skin. These beneficial effects are achieved through the activation of cutaneous autophagy, as evidenced by an increase in Beclin-1 expression and a decrease in mTOR content in the skin.

Abstract
Diet is known to play a role in the development of skin disorders. While a vegan diet is frequently described as a risk factor for skin disease secondary to nutritional deficiency, this risk may be overestimated. This review aims to debunk myths and provide information on skin disorders and inflammatory skin conditions that have associations with specific nutritional deficiencies in the context of a vegan diet. A literature search was performed for each nutrient and inflammatory skin disease using the PubMed/MEDLINE database and public health website pages concerning a vegan diet. The literature has individual cases reporting skin disease due to deficiencies in vitamin B2 and vitamin A in patients following a vegan diet. The recommended daily amounts of nutrients and vitamins can be fulfilled on a vegan diet. Vegan diets also avoid food groups such as dairy and other animal-based products, which holds benefits in inflammatory skin diseases including acne, psoriasis, hidradenitis suppurativa, and atopic dermatitis. Overall, the risk of skin disease secondary to nutritional deficiency in patients following a vegan diet is very low and likely over-emphasized. A well-balanced and conscientiously planned vegan diet can adequately provide the necessary amounts of proteins, vitamins, and minerals to support skin health.

Abstract
BACKGROUND Hidradenitis suppurativa affects up to 4% of the population worldwide. Many treatment options exist but these come with a significant side-effect profile. Exercise, weight loss, and dietary modifications may be simple inexpensive alternatives and/or adjuncts to treating this disease. OBJECTIVES We aimed to summarize published evidence on the effects of dietary, weight loss, and exercise interventions on the clinical course, severity, or subjective improvement of hidradenitis suppurativa and to provide a framework regarding dietary changes and exercise modalities for clinicians treating this disease. METHODS A literature search of Scopus (1993 onwards), PubMed (1986 onwards), and MEDLINE (OVID interface, 1946 onwards) was conducted on 22 October, 2022. Case-control studies, cohort studies, and randomized controlled trials with five or more subjects conducted on adult participants (aged >18 years) were included; case reports, case series, and review papers were excluded. RESULTS Fifteen studies involving 2829 patients were included, encompassing nine cohort studies, five cross-sectional studies, and one cross-over study. Patients who were female, lost more than 50 pounds (22.7 kg), or were obese prior to weight loss saw improvement in hidradenitis suppurativa severity with weight loss. There was evidence for beneficial effects of diets, such as the Mediterranean diet that minimizes sugar, highly processed carbohydrates, and dairy, and emphasizes chicken, fruits, and vegetables, in patients with hidradenitis suppurativa. Evidence also supported benefit from oral zinc and vitamin D supplementation. CONCLUSIONS More evidence is needed in the form of randomized controlled trials or well-designed controlled trials to evaluate the effect of exercise and dietary manipulation on the hidradenitis suppurativa disease course. Overall, there is significant but weak evidence to support improvement in hidradenitis suppurativa severity with weight loss, dietary changes, and micronutrient supplementation. There is no significant evidence to support improvement in hidradenitis suppurativa symptomology with any type of exercise intervention. CLINICAL TRIAL REGISTRATION This protocol was registered with PROSPERO with the registration number CRD4202235099.

Abstract
The consumption of cow's milk is a part of the basic nutritional habits of Western industrialized countries. Recent epidemiological studies associate the intake of cow's milk with an increased risk of diseases, which are associated with overactivated mechanistic target of rapamycin complex 1 (mTORC1) signaling. This review presents current epidemiological and translational evidence linking milk consumption to the regulation of mTORC1, the master-switch for eukaryotic cell growth. Epidemiological studies confirm a correlation between cow's milk consumption and birthweight, body mass index, onset of menarche, linear growth during childhood, acne vulgaris, type 2 diabetes mellitus, prostate cancer, breast cancer, hepatocellular carcinoma, diffuse large B-cell lymphoma, neurodegenerative diseases, and all-cause mortality. Thus, long-term persistent consumption of cow's milk increases the risk of mTORC1-driven diseases of civilization. Milk is a highly conserved, lactation genome-controlled signaling system that functions as a maternal-neonatal relay for optimized species-specific activation of mTORC1, the nexus for regulation of eukaryotic cell growth, and control of autophagy. A deeper understanding of milk´s impact on mTORC1 signaling is of critical importance for the prevention of common diseases of civilization.

Abstract
Hidradenitis suppurativa / acne inversa (HS) is a chronic inflammatory, debilitating skin disorder with a largely unknown etiology. However, many observations such as the typical onset of the disease after puberty, the female predominance, the pre-menstrual flare ups and the improvement during pregnancy suggest a contribution of endocrinological factors to the emergence of the disease. In addition, the reported efficacy of anti-androgen treatment on HS indicates a possible involvement of androgens in the pathogenesis. Furthermore, the common comorbidity with metabolic syndrome points to possible interactions between endocrinological and metabolic alterations in the development of HS. Taking into account the endocrine functions of the human skin, several studies investigated the effects of hormones and the behavior of the pilosebaceous unit in the skin of patients with HS. In this review we describe the current view on the hormonal dysregulation and metabolic syndrome and their role in HS.

Abstract
Acne is estimated to affect 9.4% of the global population, making it the eighth most prevalent disease worldwide. Epidemiological studies have demonstrated that acne is most common in postpubescent teens, with boys most frequently affected, particularly with more severe forms of the disease. This paper aims to provide an update on the epidemiology of acne worldwide. Recent general and institutional studies from around the world have shown that the prevalence of acne is broadly consistent globally (with the exception of specific populations, which are discussed). However, this review highlights that there is a wide range of disparate outcome measures being applied in epidemiology studies, and we emphasize the need to develop a widely accepted, credible, standard assessment scale to address this in the future. In addition we discuss special populations, such as those devoid of acne, as well as the impact of potential determinants of acne on disease epidemiology.

Abstract
Full control of hidradenitis suppurativa requires the prevention of new lesions. These appear to be induced by a complex series of hormonally driven molecular activities that lead to obstruction of the follicular duct, rupture and destruction of the sebaceous glands, the development of deep dermal sinuses that subsequently rupture to the surface, and production of an invasive subcutaneous mass that is resistant to medical therapy. Preliminary observations suggest that the use of a healthy and fully natural zero dairy and low glycemic-load diet may provide relief from progression of the lesions and possibly prevention of new lesions, even when medications fail.

Abstract
Hidradenitis suppurativa is a chronic relapsing disorder of the folliculopilosebaceous units (FPSUs). Its negative impact on quality of life is extreme, mainly due to the lack of early recognition, accurate diagnosis, and appropriate management. The support structure of the FPSUs is defective. Under the influence of endogenous reproductive hormones, exogenous hormones, androgens and their precursors in dairy products, and other dietary factors, the follicular unit is plugged and distended by retained keratin. Friction, shearing forces, and pressure lead to rupture and leakage of the ductal contents from the weakened FPSU, causing an inflammatory reaction mediated mainly by the innate immune system. Therapy requires patient comprehension and cooperation, counseling, aggressive hormonal and dietary modification, avoidance of the trauma that leads to rupture, active multimodal anti-inflammatory therapy, and early unroofing and debridement. The full therapeutic program is needed to avoid the aggressive surgery required if the condition is not diagnosed early and managed appropriately.

Abstract
Acne vulgaris is the most common cutaneous disorder affecting adolescents and young adults. Some studies have reported an association between serum zinc levels and acne vulgaris. We aimed to evaluate the serum zinc level in patients with acne vulgaris and compare it with healthy controls. One hundred patients with acne vulgaris and 100 healthy controls were referred to our clinic. Acne severity was classified according to Global Acne Grading System (GAGS). Atomic absorption spectrophotometry was used to measure serum zinc levels. Mean serum level of zinc in acne patients and controls was 81.31 ± 17.63 μg/dl and 82.63 ± 17.49 μg/dl, respectively. Although the mean serum zinc level was lower in acne group, it was not statistically significant (P = 0.598). There was a correlation between serum zinc levels with severity and type of acne lesions. The results of our study suggest that zinc levels may be related to the severity and type of acne lesions in patients with acne vulgaris. Relative decrease of serum zinc level in acne patients suggests a role for zinc in the pathogenesis of acne vulgaris.
