- Abstract: Background: Although changes in skin depend on the external environment, researchers have performed only a few studies on effect of the actual environment. Most studies have researched skin characterization based on changes in the humidity or temperature. Aim/objective: This study aimed to evaluate changes in the skin based on the difference in indoor and outdoor temperatures and humidity during summer in South Korea and Southeast Asia. Methods: Twenty‐two female participants aged 25–39 years were included. Skin hydration, sebum (cheek, forehead), colour, transparency and pores of the participants were measured after a 30‐min exposure to high temperature and high humidity (HTHH) environment and a 30‐min exposure to low temperature and low humidity (LTLH) environment. Subsequently, exposure to HTHH environment for 30 min +LTLH environment for 30 min was performed after a total of 1 h and repeated. Results: Repeated exposure to HTHH and LTLH environments increased the skin's sebum content and haemoglobin index. Additionally, skin elasticity was significantly reduced, with patients in their 30 s showing greater changes than those in their 20 s. Conclusion: Repeated differences in temperature and humidity cause skin ageing, loosen skin vessels and reduce skin elasticity, thereby leading to skin ageing.

Résumé: Contexte: Bien que les changements cutanés dépendent de l'environnement extérieur, les chercheurs n'ont réalisé que quelques études sur l'effet réel de cet environnement. La plupart des études ont examiné les caractéristiques de la peau en fonction des changements d'humidité ou de température. But/Objectif: Cette étude visait à évaluer les changements de la peau en fonction de la différence de température et d'humidité à l'intérieur et à l'extérieur pendant l'été en Corée du Sud et en Asie du Sud‐Est. Méthodes: Vingt‐deux femmes âgées de 25 à 39 ans ont participé. L'hydratation de la peau, le sébum (joues, front), la couleur, la transparence et les pores des participants ont été mesurés après une exposition de 30 min à une température élevée et à un environnement à forte humidité (« high temperature and high humidity », HTHH) et une exposition de 30 min à une température faible et à un environnement à faible humidité (« low temperature and low humidity », LTLH). Par la suite, l'exposition à l'environnement HTHH pendant 30 min + environnement LTLH pendant 30 min a été effectuée après une durée de 1 h, puis répétée. Résultats: L'exposition répétée aux environnements HTHH et LTLH a augmenté la teneur en sébum et l'indice d'hémoglobine de la peau. En outre, l'élasticité de la peau était significativement réduite, les patientes ayant dépassé la trentaine montrant des changements plus importants que celles dans la vingtaine. Conclusion: Les variations répétées de température et d'humidité provoquent le relâchement des vaisseaux cutanés et réduisent l'élasticité de la peau, aboutissant ainsi au vieillissement de la peau. … (more)
