What are the benefits of sea salt in skincare?

In skincare, sea salt is primarily used for its exfoliating properties, helping to remove dead skin cells and smooth skin texture. It can also contribute minerals to the skin and is sometimes used to absorb excess oil.

Can sea salt be irritating to the skin?

Yes, due to its abrasive nature as a physical exfoliant and its drying properties, sea salt can be irritating, especially for sensitive or compromised skin. It should be used gently and sparingly, particularly on the face.

Sea Salt

Sea salt is naturally occurring salt obtained from evaporated seawater, primarily composed of sodium chloride along with trace minerals. In cosmetics, it is often used as an exfoliant, a texturizer, or to provide mineral benefits. It can also act as a natural preservative in some formulations.
