Maris Sal (sea salt) is a naturally derived mineral salt used in cosmetics primarily as a mild exfoliant, viscosity controller, and bulking agent, and it can also provide mineral content and mild antimicrobial benefits in bath and skincare products. Its function varies with concentration, acting as a scrub abrasive in higher amounts and a texturizing or osmotic agent in lower amounts.
| Reported effect | How often | Notes |
|---|---|---|
Skin dryness | Common | Salt's osmotic and dehydrating properties can reduce skin moisture with frequent use. |
Mechanical irritation or microtears | Uncommon | Coarse salt particles used as a scrub can cause abrasion, especially on sensitive or compromised skin. |
Stinging or burning on broken skin | Uncommon | Contact with cuts, abrasions, or active eczema can cause transient stinging. |
Contact dermatitis or sensitivity | Rare | Irritant rather than allergic reactions are more typical; true allergy is uncommon. |
Worsening of inflammatory conditions | Rare | Aggressive scrubbing may aggravate acne, rosacea, or sensitive skin. |
