“…Furthermore, the vermilion border is a body site particularly susceptible to water loss, with consequences in the surface smoothness, shape, tactile sensitivity, and healthy appearance [21]. Capacitance is a method recognized worldwide for establishing skin hydration [22][23][24][25][26]; therefore, since the skin is covered by an, albeit thinner, epithelial layer, it is possible to employ the same tool for assessing lip water content, as also shown in previous studies [27][28][29].…”

Além disso, questões voltadas à preocupação com o meio ambiente e natureza ecológica também são abordadas para essa gama de produtos(SANDEWICZ, 2007; NORMASARAH; ASRUL, 2014; ANILKUMAR; DHANARAJU, 2020).JORNET; CAMACHO-ALONSO;RODRÍGUEZ-ESPIN, 2010;TAMURA et al, 2018), e o epitélio caracterizado como um tecido fino, levemente queratinizado e com menor conteúdo de ceramidas(KIM et al, 2019;GFELLER et al, 2019).Devido a sua proeminente localização na região facial, os lábios estão constantemente suscetíveis às influências do ambiente externo, como a radiação solar, ventos e temperaturas extremas, bem como, a tratamentos estéticos, incluindo os cosméticos e produtos dentários. Dos diferentes mecanismos da pele, o estado de hidratação do EC é o mais comumente alterado no cotidiano(GUEST et al, 2013) e para que uma barreira intacta seja mantida na epiderme, a quantidade adequada de água precisa estar presente nessa superfície(PALMA et al, 2015).…”
