What benefit does a salt treatment provide for the skin?

A salt treatment primarily provides an exfoliating benefit for the skin. Salt, particularly in a scrub or treatment form, has properties that help remove dead skin cells from the surface. This exfoliation process uncovers newer, healthier skin underneath, promoting a brighter and more even skin tone.

Additionally, while salt can have moisturizing and detoxifying effects in certain contexts, its most notable and immediate benefit in a treatment setting is its ability to slough off dead skin, making the skin feel smoother and softer after use. This aligns with the role of exfoliation as a key component of skin care routines.

When considered alongside other options, while moisturizing and detoxifying can be secondary benefits associated with salt treatments, the primary action is exfoliation, making it the most consistent and direct benefit of using salt on the skin.
