Seawater contains high levels of salt and minerals that help to hydrate and soothe skin.  

The salt in seawater acts as a gentle exfoliant, removing dead skin cells and
improving skin texture.

The salt and minerals in seawater can help to remove dirt, oils and impurities from the skin, leaving it feeling refreshed and clean.

Seawater has been known to help relieve conditions like
eczema, psoriasis and acne.

Seawater is slightly alkaline, which can help to balance the skin's
natural pH levels and maintain its overall health.
