Endocrine disruptors (EDs) are molecules capable of mimicking the natural hormones of the body and interfering with the endocrine system in both humans and wildlife. Cosmetic products are one source of EDs; these include an extensive variety of personal care and beauty products designed for the skin and hair, as well as makeup. The widespread use of such products has raised concerns about the presence of EDs within them. In this study, we highlight the issue of EDs and analyze the functioning of the EU regulatory framework for chemicals, specifically those which act as EDs in cosmetic products. We also highlight issues related to the interface between science and policy in the critical area of risk regulation within the EU. In addition, we investigate how chemical substances that act as EDs are identified based on specific criteria and conditions, a process which involves the production and adoption of particular scientific opinions. Finally, we assess the efficiency, suitability, and effectiveness of the regulatory framework in this sensitive area of human exposure to chemicals, especially those that function as EDs.

Food technology, health, nutrition, dermatology, and aesthetics have focused on colorless carotenoids. Carotenoids are readily bioavailable and have demonstrated various health-promoting actions. This article reviews the recent literature concerning carotenoids with the aim to systematize the scattered knowledge on carotenoids and aesthetics. The applications of carotenoids in health-promoting and nutrient products and their potential health effects are discussed. The carotenoids, particularly phytoene and phytofluene, have the unique ability to absorb ultraviolet radiation. Their distinct structures and properties, oxidation sensitivity, stiffness, aggregation tendency, and even fluorescence in the case of phytofluene, contribute to their potential benefits. A diet rich in carotenoid-containing products can positively impact skin health, overall well-being, and the prevention of various diseases. Future studies should focus on generating more data about phytoene and phytofluene levels in the skin to accurately assess skin carotenoid status. This expanding area of research holds promise for the development of novel applications in the fields of health and cosmetics.

High-intensity focused ultrasound (HIFU) is a non-invasive technology widely used for facial and body rejuvenation, skin tightening, and fat reduction. It stimulates collagen production and induces apoptosis in fat cells, offering an effective alternative to surgical procedures with minimal downtime and reduced recovery periods. As a result, HIFU has become an increasingly popular choice for patients seeking non-surgical esthetic enhancements. A comprehensive literature search was conducted using PubMed, Scopus, and SpringerLink to assess HIFU-related complications. Twenty-two studies published between 2010 and 2025 were identified, all involving female participants. The findings confirm that HIFU is generally safe and effective, with most complications being mild and transient, such as temporary erythema, swelling, and discomfort. These side effects typically resolve within a few hours to days without requiring medical intervention. However, rare but significant complications like fat atrophy, nerve irritation, and hyperpigmentation have been linked to improper device settings, inadequate practitioner expertise, and insufficient patient assessment. Ensuring proper training, adherence to standardized treatment protocols, and individualized patient evaluations can significantly minimize these risks and optimize patient outcomes. Long-term follow-up studies and further research on standardized safety protocols, optimal energy settings, and patient selection criteria are essential for enhancing the effectiveness, predictability, and safety of HIFU in esthetic medicine.

Molluscum contagiosum (MC) and warts are common viral infections of the skin. Data regarding the prevalence of MC and verruca in swimmers are very poor and lacking in the literature. The purpose of this study was to determine the incidence of Molluscum Contagiosum (MC) and warts cases among young competitive swimmers participating in Greek swimming clubs. Of 244 swimmers enrolled in this study, 12.3% reported MC and 43% warts, during their swimming career, diagnosed and treated by dermatologists. There was no difference between sexes for MC but diagnoses of warts were higher in females. Axillae and trunk were the most common sites of primary infection for MC but warts mainly appeared on the soles. The incidence of MC and warts in swimmers who use outdoor facilities was higher. In our study, the incidence of warts and MC in Greek swimmers is considered high. Moist walking surfaces, placing towels on locker room benches, and sharing equipment are behaviors that cause infections. An early diagnosis of warts and MC lesions must be implemented in every swimmer through dermatological examination. Taking proper measures for reducing the risk of warts and MC transmission in Greek swimmers is mandatory.

The interplay between nutrition and skin health provides a crucial lens for understanding, diagnosing, and managing eating disorders (EDs) such as anorexia nervosa (AN), bulimia nervosa (BN), and binge-eating disorder (BED). This review explores the dermatological manifestations resulting from the nutritional deficiencies commonly associated with EDs, including conditions like hair loss, xerosis, and brittle nails. These changes in the skin and its appendages often reflect deeper systemic dysfunctions, such as deficiencies in essential micronutrients (zinc, iron, and vitamins A and C), hormonal imbalances, and electrolyte disturbances. Recognizing these dermatological signs as diagnostic tools is vital for the early identification and intervention of EDs. By integrating dermatological observations with psychiatric and nutritional care, a holistic, multidisciplinary approach can be developed to address both the physical and psychological complexities of EDs. This review highlights the critical role of these skin-related markers in promoting timely diagnosis and effective treatment. To examine the relationship between specific nutrients and dermatological manifestations in EDs, a systematic review of three electronic databases—PubMed, Google Scholar, and ResearchGate—was conducted. The findings underline the importance of early recognition of these skin symptoms for effective management. Collaborative care involving dermatologists, psychiatrists, and nutritionists is essential for diagnosing and treating EDs. Such integrated efforts ensure a comprehensive approach to these multifaceted conditions, ultimately improving patient outcomes and enhancing overall care.

Viral outbreaks are common in the sport community. Data regarding the prevalence of plantar warts, genital warts, herpes simplex type 1 (herpes labialis), herpes zoster, and genital herpes in competitive swimmers are lacking in the literature. The purpose of this study was to determine the prevalence of those viral infections among young competitive swimmers participating in Greek swimming clubs. Swimmers’ parents and adult swimmers were asked to complete an anonymous questionnaire. In total, 1047 swimmers enrolled in this study. The measured parameters included gender, age, times of infections, and seasons when athletes may be more susceptible to infections. Practicing information such as type of swimming facility, number of training years, average hours of daily training, behaviors in swimming practice, and sunlight exposure was also recorded. All infections showed a significant difference in relation to “age” and “years of training”. The gender significance was observed in herpes labialis (p = 0.016) and plantar warts (p = 0.05). The prevalence of all infections in swimmers who use outdoor facilities was higher. Certain behaviors such as walking barefoot on a pool deck and sharing swimming equipment correlate with herpes simplex and plantar warts. Virus infections can affect swimmers of all ages. In our study, plantar warts and herpes labialis are more common in swimmers. Herpes zoster and sexually transmitted viruses are rarer and affect adult swimmers. The impact of cutaneous infections on swimmers can affect performance and well-being. Effective prevention and management are essential to avoid complications. Proper hygiene, medical guidance, and treatment reduce swimmers’ exposure to skin viruses.
