The Essential Nutrients in Rice Water: A Skin Care Guide

The crowning jewel in our super-water crown is rice water: the starchy water left over from soaked rice.

Today, it reigns supreme in K-beauty, J-beauty, and beyond as a popular ingredient in brightening skin care products.

4 Key Nutrients in Rice Water for Skin

Using rice water for the skin can be an excellent way to encourage UV protection while softening and brightening the skin. A 2013 study proved that rice water can reduce UV damage.

Rice water may even hold restorative properties for skin, especially skin that’s been exposed to harsh weather or hard work. These properties are often attributed to rice water’s centuries-old reputation for preserving the hands of Japanese women, who worked long days in the rice fields.

It’s helpful to understand that while rice water might be just one ingredient, it’s made up of a plethora of beneficial nutrients. Thanks to its abundance of vitamins, amino acids, and minerals, rice water is known to soothe and tone skin while offering relief to those with skin sensitivities.

Let’s take a look at just four of the many nutrients found in rice water for skin!

#1: Kojic Acid
One of the most noted ingredients in rice water is kojic acid: renowned for its skin-brightening abilities, antifungal properties, and antibacterial functions.

Kojic acid’s most popular function in rice water for skin has to do with its influence on melanin production. Melanin is the natural pigment that gives skin its range of unique and beautiful shades. It’s also one of the main components of scar tissue and dark spots.

Kojic acid can brighten the skin and help fade scar tissue by lowering the production of tyrosine, an amino acid necessary for supporting melanin production. Additionally, kojic acid’s antifungal and antibacterial properties can help prevent acne-causing bacteria.

The science behind kojic acid’s work as a lightening agent involves its effect on melanin production. Melanin is a naturally occurring pigment in the body that gives the eyes, hair, and skin their color. An amino acid called tyrosine is needed to support the production of melanin.

Kojic acid works by blocking tyrosine from forming, which then prevents melanin production. Decreased melanin production may have a lightening effect on the skin.

#2: Ferulic Acid
Rice water, like many plant-based ingredients, is loaded with antioxidants for your skin. One such antioxidant is ferulic acid; it’s perfectly suited for fighting the harmful free radicals that can wreak havoc on our skin, making it ideal for anti-aging.

Ferulic acid is also a fantastic antioxidant to see working in tandem with other antioxidants like vitamins C and E. While providing powerful free radical defense, these vitamins also have a reputation for unstable shelf lives. Ferulic acid, however, can help keep these antioxidants stable. This 2005 study also suggests that ferulic acid’s photoprotective factors are doubled when combined with vitamins C and E.

#3: Vitamin E
Vitamin E is a powerful, fat-soluble antioxidant known for its ability to reduce inflammation and help support skin and immune health while combating free radicals.

The vitamin E content found in rice water for skin and hair care may also help relieve UV damage, which is primarily caused by overexposure to the sun. According to Oregon State University, vitamin E provides its unique sun protection by absorbing UV rays, endowing it with shield-like powers against environmental exposure.

#4: Allantoin
Allantoin is a powerhouse compound found in a variety of plants known for their soothing properties, like chamomile and comfrey.

Known for its versatility, allantoin has an aptitude for moisturizing the skin by hydrating and discouraging dryness. It’s also able to soothe the skin while encouraging brightness. Allantoin can also work as a potent anti-aging ingredient, by encouraging collagen production and stimulating fibroblasts. In short, that means it may promote more supple, bouncy skin while lessening the appearance of lines and wrinkles.
