The concept of 'skin barrier' has gained significant popularity in both Brazilian and American skincare and wellness culture in recent years. In Brazil, K-beauty and cosmetic trends have popularized the term 'barreira cutânea' in the beauty industry, with many products marketed as 'barrier-repair' or 'barrier-strengthening.' In the USA, this term is widely used in dermatology, skincare marketing, and on social media platforms. The term reflects a shift toward understanding skin health through a scientific lens rather than merely cosmetic concerns.
