Skin Hydration Effect of Jeju Lava Sea Water

Abstract

Many minerals and nutrient salts are abundant in Jeju lava sea water. The objective of this study was to evaluate the skin hydration effects of Jeju lava sea water. The skin barrier serves as a protective barrier that prevents the loss of moisture. The water holding capacity and water transport of the epidermis have been proposed to be important determinants of skin hydration. Jeju lava sea water increased the mRNA expression of filaggrin and caspase-14 which is related to natural moisturizing factor (NMF) formation. Aquaporins 3 (AQP3) are proteins that facilitate the transport of water across cell membranes. Jeju lava sea water increased the mRNA expression and protein expression of AQP3. We employed a skin equivalent model to assess the efficacy of Jeju lava sea water. In a skin equivalent model, Jeju lava sea water increased the CD44 (hyaluronic acid receptor) which is related to skin hydration. From these results, we found out Jeju lava sea water maybe help to skin hydration.

“…이러한 미네랄 성분을 포함하는 제주 용암해수의 식이 섭취를 통해 항산화, 항염 효능을 보 고한 연구 결과도 존재한다 (Kim et al, 2020a). 제주 용암해수는 피 부의 보습 효능 또한 가진다고 알려져 있다 (Lee et al, 2016). 각질 형성세포에서 제주 용암해수는 피부 내 천연보습인자 생성을 증가시 키고 수분의 수송과 관련된 막 단백질의 발현 역시 증가시킨다고 보 고되어 있다 (Lee et al, 2016).…”

“…10 Mineral-rich water in Jeju is also known to have moisturizing effects on the skin and increase the expression of membrane proteins involved in transport protein. 11 In a previous study, we reported improved biological effects on skin metabolism caused by the use of ground sea water with a high mineral composition. 12 In Jeju, we further demonstrated the biological efficiency of combining ARE with mineral-rich water.…”
