Do you know the benefits of rice cooking water for the skin?

Many people use rice water for the skin, either to improve its appearance or to relieve conditions such as eczema. Rice water is the starchy liquid left over after soaking or boiling the rice. One can prepare rice water at home or buy skin care products that contain rice water. This article examines the potential benefits of rice water for the skin, how to prepare it and how to use it.

Is rice cooking water good for the skin?

Rice water may have some skin benefits. Even though there are currently few quality studies on the effects of rice water.

Here’s what the existing research says about the potential benefits of rice water:


Rice contains antioxidants, such as inositol. Antioxidants help fight the effects of free radicals, which are volatile molecules that can damage cells in the body. Companies often add antioxidants to skin care products.
A small 2018 study of 12 participants tested rice water gel on the skin for 28 days. The researchers found that rice had the same antioxidant activity as ascorbic acid, or vitamin C.

Reduce skin aging

There is little evidence that rice water can reduce or slow skin aging. A 2018 study, however, showed that rice water reduced the activity of elastase, an enzyme involved in skin aging. This suggests that rice water may have the potential to reduce the formation of fine lines and wrinkles on the skin.
According to a 2001 study, inositol could smooth out existing wrinkles. Researchers tested a 1% or 2% inositol moisturizer on women of different ages for 7 weeks. At the end of the study, researchers estimated that inositol reduced wrinkle size by 12.4% and increased elasticity by 17%.
However, it is important to note that both of these studies were small.

Reduce skin irritation

In 2002, researchers tested the effects of swimming in water containing rice starch on two groups: people with atopic eczema and those whose skin was irritated by sodium lauryl sulphate (SLS). They found that the healing ability of the skin improved by 20% in people with irritation from SLS. This happened after people bathed in the rice starch mixture for 15 minutes twice a day. The skin barrier also improved with this treatment in people with atopic eczema.

Dandruff treatment

Preliminary research suggests that fermented rice water may inhibit the growth of certain fungi. A 2013 lab study found that rice water contains Bacillus cereus bacteria. It produces the antibiotics zwittermicin A and kanosamine. These antibiotic substances can inhibit the growth of Malassezia furfur, which can cause dandruff.
However, since this was a laboratory study, it does not necessarily prove that fermented rice water is an effective treatment for dandruff in humans.

How to make rice water

There are several methods to make rice water:

– Soaking: Soak 1/2 cup of uncooked rice in 2-3 cups of water for 30 minutes.
– Boil: Cook the rice by boiling it in double the amount of water normally used for cooking.

After cooking, strain the water into a clean bowl or bottle for immediate use. Store the rest in a clean container in the refrigerator. To obtain fermented rice water, use the steeping method and then leave the rice water at room temperature for 1-2 days. Then store it in the refrigerator.

Rice water is safe to use for about a week. It is advisable to discard any older rice water. People allergic to rice should not use rice water.
