Abstract：
Skin aging is the result of physiological changes determined by genetically driven processes and intrinsic factors, and exacerbated by a combination of multiple environmental factors, the main one being sun exposure. The effects of photoaging are particularly apparent on the face, where the appearance of aging signs can have a significant impact on the emotions conveyed and well-being. Photoprotection and facial skin care for managing photoaging signs are thus of particular importance for both physical and mental health. Countries, like Australia and Brazil, where the level of sun exposure is high and the populations have predominantly outdoor lifestyles, are particularly aware of the harms of photoaging and have implemented several measures to help reduce the risk of skin cancer in their populations. However, sun-seeking behaviours are difficult to change, and it takes time before interventions provide perceptible results. Australia still has some of the highest skin cancer incidence and mortality rates in the world. Solutions that target individuals can also be used for minimizing the clinical signs of facial aging and for improving skin quality, with the ultimate aim being not only to improve the appearance of the skin but also to mitigate the occurrence of pre-malignant and malignant lesions. This review summarizes the features of facial skin photoaging in photo-exposed populations, based on evidence gained from studies of Australian individuals, and discusses the various available solutions for skin photoaging, in particular those that are most popular in Brazil, which is a country with many years of experience in managing photoaged skin.
摘要：
皮肤老化是由基因驱动的过程和内在因素决定的生理变化的结果，并因多种环境因素的组合而加剧，主要是阳光照射。光老化的影响在面部尤其明显，老化迹象的出现会对所传达的情绪和幸福感产生重大影响。因此,用于管理光老化迹象的光保护和面部皮肤护理对于身体和心理健康都特别重要。国家,像澳大利亚和巴西，那里的阳光照射程度很高，人群主要是户外生活方式，特别意识到光老化的危害，并采取了一些措施来帮助降低其人群患皮肤癌的风险。然而,寻求阳光的行为很难改变，干预措施需要时间才能提供可感知的结果。澳大利亚仍然是世界上皮肤癌发病率和死亡率最高的国家之一。针对个体的解决方案也可用于最大限度地减少面部老化的临床症状和改善皮肤质量，最终目的不仅是改善皮肤的外观，而且是减轻恶性前和恶性病变的发生。这篇综述总结了光暴露人群面部皮肤光老化的特征，根据对澳大利亚人的研究获得的证据，并讨论了皮肤光老化的各种可用解决方案，尤其是那些在巴西最受欢迎的，这是一个拥有多年管理光老化皮肤经验的国家。
