“…For instance, adherence to the Mediterranean diet, specifically the use of extra virgin olive oil as the primary fat in the diet, reduced the disease severity among patients with suppurative hidradenitis by reducing the Hurley stage and the severity score [ 71 ]. Moreover, adherence to the Mediterranean diet seems to be negatively associated with the severity of acne; thus, increasing the consumption of foods specific to the Mediterranean diet can benefit people with acne [ 70 , 72 ].…”

Psoriasis is a chronic inflammatory skin disease with autoimmune pathogenic characteristics and is caused by chronic inflammation, which results in uncontrolled keratinocyte growth and defective differentiation. The link between the gut microbiota and immune system regulation opened a novel angle to understand the pathogenesis of many chronic multifactorial diseases, including psoriasis. Current evidence suggests that modulation of the gut microbiota, both through dietary approaches and through supplementation with probiotics and prebiotics, could represent a novel therapeutic approach. The present work aims to highlight the latest scientific evidence regarding the microbiome alterations of psoriatic patients, as well as state of the art insights in terms of microbiome-targeted therapies as promising preventive and therapeutic tools for psoriasis.

“…The study revealed that adherence to the MD is not associated with acne diagnosis or severity. In contrast, three previous studies adopting a case‒control design have suggested that high adherence to the MD may be protective against acne [ 39 – 41 ]. This contrast may be attributed to variations in research settings and methodologies, thereby limiting comparisons to the present study.…”

“…Moreover, the content and arrangement of the questionnaire were found to be culturally appropriate for the population targeted in this study. Furthermore, previous studies exploring the association between adherence to the MD and acne use the same tool for assessment, which might facilitate comparison to these studies [ 40 , 41 ]. The MEDAS questionnaire comprised 12 inquiries regarding the frequency of food consumption and two queries related to dietary habits.…”

Background Western diets, characterized by a high glycemic index and dairy content, can be risk factors for acne vulgaris. A few studies have suggested that adherence to non-Western diets, such as the Mediterranean diet (MD), may be protective against acne. This study aimed to explore the relationships between adherence to the MD and acne diagnosis and severity. Methods This was a matched case‒control study carried out among university students studying health sciences to explore the relationship between adhering to the MD and an acne diagnosis. Convenience sampling was utilized for the initial recruitment of eligible participants, who were then 1:1 individually matched for age, gender, and body mass index (BMI). Adherence to the MD was assessed using the Mediterranean Diet Adherence Screener (MEDAS) tool, and acne severity was assessed using the Global Acne Grading System (GAGS). The data were analyzed using descriptive statistics, bivariate analysis, and conditional logistic regression, which included two models based on clinical data and the backward elimination technique. Results A final sample of 121 cases was individually matched to 121 controls. Each group consisted of 28.9% males and 71.1% females, with most having a BMI within the healthy range (71.9%). Both the case (80.2%) and control groups (77.7%) demonstrated a predominant pattern of low adherence to the MD. At the bivariate level, family history significantly differed between the case and control groups (OR = 2.01, CI = 1.17–3.44), while adherence to the MD (OR = 0.86, CI = 0.46–1.60) did not reach statistical significance. According to the regression analysis, family history remained significant in the backward elimination model (aOR = 1.94, CI = 1.14–3.34), while it disappeared in the full model (aOR = 1.95, CI = 1.14–3.34). Neither model revealed a significant association between acne and the other variables. Among the participants in the case group, neither adherence to the MD nor adherence to its components was significantly associated with acne severity, except for vegetables (p = 0.022). Conclusions Adherence to the MD was not correlated with acne diagnosis or clinical severity. More research on the association between acne and adherence to the MD is needed, as earlier studies are few, were conducted in specific settings, and used variable methodologies. To improve the validity and reliability of the research methodology, the development of detailed and culturally adapted MD definitions and practical guides is recommended.

Background Acne pathophysiology includes a complex interaction among inflammatory mediators, hyperseborrhea, alteration of keratinization and follicular colonization by Propionibacterium acnes. Aims To describe the impact of the exposome on acne and how photoprotection can improve outcomes. Methods A narrative review of the literature was carried out; searches with Google Scholar and Pubmed from January 1992 to November 2022 were performed. The keywords used were “acne,” “sunscreens,” “photoprotection,” “cosmetics,” “cosmeceuticals,” “pathogenesis,” “etiology,” “exposome,” “sunlight,” “stress,” “lack of sleep,” “diet,” “postinflammatory hyperpigmentation,” “pollution,” “exposome,” “ultraviolet radiation,” and “visible light.” Results Environmental factors such as solar radiation, air pollution, tobacco consumption, psychological stress, diverse microorganisms, nutrition, among others, can trigger or worsen acne. Solar radiation can temporarily improve lesions. However, it can induce proinflammatory and profibrotic responses, and produce post‐inflammatory hyperpigmentation and/or post‐inflammatory erythema. While photoprotection is widely recommended to acne patients, only four relevant studies were found. Sunscreens can significantly improve symptomatology or enhance treatment and can prevent post‐inflammatory hyperpigmentation. Furthermore, they can provide camouflage and improve quality of life. Based on acne pathogenesis, optimal sunscreens should have emollient, antioxidant and sebum controlling properties. Conclusions The exposome and solar radiation can trigger or worsen acne. UV light can induce post‐inflammatory hyperpigmentation/erythema, and can initiate flares. The use of specifically formulated sunscreens could enhance adherence to topical or systemic therapy, camouflage lesions (tinted sunscreens), decrease inflammation, and reduce the incidence of post‐inflammatory hyperpigmentation/erythema.
