Sea Salt
Sea salt is the salt left behind when seawater evaporates, mainly sodium chloride, used as a gentle scrub or texture agent. Checked against our library November 6, 2026.
What Sea Salt does
- Gives gentle physical exfoliation
- Adds grit and texture to scrubs
- Adds small amounts of natural minerals
Sea salt is made by letting seawater evaporate in shallow pools, so the water leaves and the minerals stay behind. Most of what remains is sodium chloride, the same compound as table salt, with small amounts of magnesium, calcium and potassium. Because the crystals are coarse and irregular, they feel gritty when rubbed on skin or nails.
Formulators use sea salt mainly as a physical exfoliant, because its grains gently buff away dead skin cells as you rub. It is water-soluble, so it dissolves quickly in wet formulas, and it keeps its grit mainly in dry or oil-based products.
Good for
Suits people who like a scrub-style texture in body and nail care.
Frequently asked questions
Is sea salt good for nails?
Sea salt is used in some nail treatments as a light texture and buffing aid. It is not a strengthening ingredient on its own. Treatments that include it are usually meant for gentle surface smoothing, and results depend on the full formula.
Can sea salt sting the skin?
It can feel stinging on cracked, chapped or freshly shaved skin. Rinse well after use if it bothers you. Most people with intact skin find it comfortable in a short scrub.
