Rice is a staple ingredient in the majority of households. It is also popularly used in the production of liquor, fertilizers, and cosmetics. With rice being part of many cuisines, many households cook rice frequently.
A common method of cooking rice involves boiling rice with water and then discarding the excess water. However, it is less known that this residual starchy water, known as rice water, has various uses and is highly beneficial to your skin.
Dermatological Benefits of Rice Water
The starch-laden residual rice water is rich in nutrients such as vitamins B, C, and E. This nutrient profile of rice can benefit your skin in the following ways:
1. Sun protection
Fermented rice water or rice wine has antioxidant properties that can help prevent sun-induced photodamage and is therefore often used in sunscreens. (1)(2) Rice bran also possesses photoprotective properties. (3)
3. Skin repair
Rice water helps improve skin damage and is thus useful in the treatment of atopic dermatitis. (5)
4. Hair growth
5. Vitiligo treatment
Rice bran can also boost melanin production and can therefore be used in treating hypopigmentation, such as vitiligo. (8)
Besides the above-mentioned uses, rice water also possesses the following benefits. However, these benefits are not highly researched and are chiefly based on anecdotal evidence.
- Anti-inflammatory. Compounds such as allantoin impart anti-inflammatory properties to rice water. This can be useful in the treatment of inflammatory disorders of the skin such as blemishes and eczema.
- Hair repair. Rice water is seen to contain inositol that may help improve hair damage.
- Astringent. Rice water may help tighten pores due to its astringent properties.
