This contribution examines the visible cutaneous signs in both works, relating them to the biologic mechanisms of skin aging, including cellular senescence, collagen disruption, and photoaging. The philosophic and ethic implications of contemporary aesthetic rejuvenation procedures are also explored, emphasizing the tension between accepting aging and undergoing medical transformation.

By the end of the 18th century, the First Chemical Revolution had examined all existing and new ideas from a fresh perspective. Foods were subjected to chemical analysis. Among the various scientists, Jean Baptiste André Dumas voiced his doubts about the nutritional value of artificially milk made to counter the shortage during the Siege of Paris (1870-1871). The traditional idea of five essential factors—namely carbohydrates, proteins, fats, salts (or minerals), and water—was also questioned. Josef Forster was the first to test the significance of minerals in nutrition and concluded that a certain critical amount of inorganic salts is needed to maintain nutrition. Gustav von Bunge, an influential scientist, criticized Forster’s observations and instructed his student Nikolai Ivanovich Lunin to investigate the idea. Lunin conducted methodical research and found that even if the artificial combination of all the nutritive factors present in milk was insufficient for complete nutrition, there must be some ‘indispensable substance’ necessary to complete the matter. This was the first experiment that initiated vitamin research. This work was not pursued further, and Nikolai Lunin’s groundbreaking contribution went unnoticed for decades.</div></div>","PeriodicalId":10358,"journal":{"name":"Clinics in dermatology","volume":"44 2","pages":"Pages 205-211"},"PeriodicalIF":2.2,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146197420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The major sources of the “sunshine vitamin” are sunlight exposure with subsequent cutaneous synthesis and oral intake in the form of supplementation or dietary consumption. Not only crucial for skeletal health, vitamin D is also linked to numerous disorders of cardiovascular, neurologic, reproductive, infectious, autoimmune, and dermatologic origins. It is a pleiotropic fat-soluble hormone that affects key factors in the pathogenesis of numerous cutaneous disorders because of its effects on the innate and adaptive immune systems and the physiology of the skin, including the integrity of the epidermal barrier. Thus, it is implicated in the development and severity of many dermatoses. Vitamin D status is dependent on numerous modifiable and nonmodifiable factors including Fitzpatrick skin type, sun exposure, sex, body mass index, physical activity, alcohol intake, season, and latitude, in addition to polymorphisms in the vitamin D receptor. In view of increasing knowledge about the overall benefits of vitamin D, it now seems necessary to focus on reaching and maintaining an optimal vitamin D status.

Treatment with potent topical corticosteroids (TCS) can help control symptoms for many patients, but complications such as atrophy and scarring often persist. Platelet‐rich plasma (PRP) has emerged as a regenerative therapy with potential application in LS. We review the clinical evidence and highlight gaps and future research needs. We searched PubMed and Web of Science databases for studies of PRP in LS. The outcomes evaluated included symptom relief, quality of life (QoL), tissue repair, and safety. The evidence regarding PRP monotherapy includes one randomized controlled trial, 11 single-arm studies, one case series, and one case report. Four studies included PRP combined with other regenerative therapies such as adipose-derived stem cells. Most studies reported benefits in symptomatic relief, sexual function, vaginal health, tissue quality, and QoL after PRP therapy. PRP appeared to work effectively alongside other regenerative treatments. The evidence is limited due to small sample sizes, lack of control groups, short follow‐up periods, inconsistent objective measures of treatment efficacy, variability in PRP preparation and injection protocols, limited use of objective endpoints, and a lack of standardized outcome measures. The safety profile of PRP appears favorable. In conclusion, PRP can serve as an adjuvant therapy for genital LS in patients who do not respond to TCS treatment or when such treatment is discontinued. More rigorous studies are needed nonetheless. The potential of combining PRP with other regenerative therapies warrants further investigation.</div></div>","PeriodicalId":10358,"journal":{"name":"Clinics in dermatology","volume":"44 2","pages":"Pages 356-362"},"PeriodicalIF":2.2,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146200367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
