Rice water is the starchy liquid obtained from soaking or boiling rice, containing carbohydrates, amino acids, vitamins (B, E), minerals, and antioxidants such as inositol and ferulic acid. It is used topically as a soothing, hydrating, and mild brightening agent, though robust clinical evidence is limited.

| Allergic contact dermatitis | Very rare | Rice protein allergy can cause reactions in sensitized individuals. |
| Microbial contamination from improper home preparation | Uncommon | Unpreserved homemade rice water can spoil, increasing risk of bacterial or fungal growth. |
