From Waste to Wonder: The Science-Backed Benefits of Rice Water and Rice Bran Oil for Skin

From Waste to Wonder: The Science-Backed Benefits of Rice Water and Rice Bran Oil for Skin

The beauty world is filled with excitement over natural, DIY skincare remedies, and one trend that has taken centre stage is the use of rice water. With roots in ancient traditions, specifically within Asian cultures, rice water has surfaced as a beauty secret worth celebrating. Yes, this pantry staple, now a popular skincare ingredient, has made a significant comeback!

The journey from humble rice water to a luxurious skincare solution, and its link to the equally powerful rice bran oil, tells a fascinating story.

The Ancient Origins of Rice Water in Skincare

Rice water, a byproduct of washing rice, has roots in ancient beauty traditions where it was used as a facial cleanser, toner, and hair rinse. Japanese and Korean women, in particular, who needed to wash rice for cooking - popularised these practices by finding uses for the leftover rice water.

How Rice Water is Good for the Skin

Rice water is the starchy liquid left after soaking, washing or even cooking rice. This starchy byproduct is precious when it comes to vitamin and mineral content. The appeal of rice water lies in its simplicity and the belief that it can enhance skin texture, reduce irritation, and promote a youthful glow. But what makes rice water effective?

1. Rich in Nutrients and Anti-Aging Benefits: Rice water contains vitamins, minerals, and amino acids that can benefit skin health. Notable components include inositol, Vitamin E, and ferulic acid, which have antioxidant properties. These ingredients help combat the effects of free radicals-unstable molecules that can cause cellular damage throughout the body.

A study also found that rice water has the potential to reduce the activity of elastase, an enzyme involved in skin aging. This suggests rice water may have the potential to reduce the formation of wrinkles. Further research is necessary to better understand rice water's potential anti-aging benefits.

2. Anti-Inflammatory and Soothing Effects: Rice water's anti-inflammatory properties make it particularly effective for soothing irritated or sensitive skin.

Based on what we know about the fantastic properties of rice water, it has the potential to help reduce inflammation in conditions like atopic dermatitis (eczema) and acne. The starch in rice water may act as a mild exfoliant, which could help with the removal of dead skin cells and promote skin regeneration.

3. Hydration and Moisture Retention: The natural starches in rice water create a film on the skin's surface, which helps to lock in moisture. This makes rice water an excellent hydrating agent.

How to Make Rice Water

  • 1 cup rice
  • 2 cups distilled water
  • Water to rinse

1. Rinse and strain your rice thoroughly (at least 2-3 times) to remove any chemicals or impurities.

2. Mix the strained rice in a medium-sized bowl with the distilled water and allow to sit for 30 minutes.

3. Strain the rice, this time reserving the water. Cook the rest of your rice.

4. Allow the rice to sit in a jar at room temperature for 12-48 hours (in warmer climates, the fermentation process will take less time). When a slightly sour smell arises from the rice water, stop the fermentation process by keeping the solution in the fridge. Remember, fermented rice water is very potent, so it's best to dilute it with 1-2 cups of distilled water before using it. The amount of dilution may also vary depending on your skin tolerance. When fermented, it becomes rich in probiotics aka good bacteria, vitamins, minerals and antioxidants.

5. Refrigerate the rice water until you're ready to use it as a lovely face spritzer/toner or simply use it to cleanse your face. Use it within a week. You can also add in a few drops of your favourite essential oils for fragrance and other beauty benefits.

6. If you want to use rice water in the water component of your formulation, you have to add a preservative to prevent potential microbial contamination. Read more on preservation here.

The Hidden Downsides: From Waste to Potential Contaminants

While rice water is often praised for its numerous benefits, several aspects should be carefully considered. One of the primary concerns is the potential presence of pesticides, heavy metals, and other contaminants in the rice. This is especially true for non-organic rice, which is more likely to be treated with chemical pesticides during cultivation.

Additionally, rice can absorb contaminants, such as arsenic, which is a significant concern in regions where the water or soil is contaminated. Arsenic is a naturally occurring element that can be toxic over time, and rice tends to absorb more arsenic compared to other crops. That's why we emphasise thorough washing of the rice, as this could potentially affect the purity and safety of the rice water. Washing rice thoroughly can reduce, but not entirely eliminate, these contaminants.

Another drawback is that the preparation process can be time-consuming and requires a significant amount of water for washing the rice, especially when making small batches. Unless you're cooking for a large group, making too much rice water can lead to leftover rice and food waste.

To maximise the benefits while minimising potential risks, one needs to use clean, filtered water and possibly consider using organic jasmine, white or brown rice. This can make the process more expensive and less accessible, particularly for those who might not have easy access to organic products or clean water.

Rice Bran Oil: A Superior Alternative

Rice bran oil, derived from the outer layer of the rice grain (bran), presents a compelling alternative to rice water. Often discarded during the milling process, rice bran was once considered waste. Research has revealed that rice bran oil has a plethora of nutrients, making it a valuable ingredient in skincare.

Packed with Essential Fatty Acids and Antioxidants:

Rice bran oil is rich in essential fatty acids like oleic acid (omega-9) and linoleic acid (omega-6), which are crucial for maintaining the skin's moisture barrier and preventing water loss. It also contains high levels of antioxidants, including:

Gamma-oryzanol: Unique to rice bran oil, this antioxidant protects the skin from oxidative damage. It also has anti-inflammatory benefits.

Squalene, Tocotrienols and Tocopherols (Vitamin E): These compounds help to neutralise free radicals, reducing signs of aging and keeping the skin plump and radiant.

Deeply Moisturising and Non-Comedogenic:

Rice bran oil, is lightweight and non-comedogenic, meaning it is less likely to clog pores. It is generally suitable for all skin types, including oily and acne-prone skin. Its deep moisturising properties help to soften the skin, reduce roughness, and improve overall texture.

Anti-Inflammatory and Healing Properties:

Similar to rice water, rice bran oil, has anti-inflammatory properties that can help to soothe irritated skin and calm conditions like eczema and dermatitis. Its ability to penetrate deeply into the skin allows it to heal and repair the skin from within, promoting a more radiant and youthful appearance.

Long Shelf Life and Stability:

In contrast to rice water, rice bran oil, has a longer shelf life when stored properly in a cool, dark place. This makes it a convenient and reliable option for daily skincare routines without the hassle.

Skin Brightening and Anti-Aging:

Just like rice water, rice bran oil contains ferulic acid, but in much higher concentrations. This makes it highly effective at brightening the skin and fading dark spots. Additionally, the oil's anti-aging properties are enhanced by its ability to deeply penetrate the skin and deliver nutrients more effectively.

The journey from rice water to rice bran oil is a story of transformation from what was once considered waste to a nutrient-rich skincare force of nature. While rice water offers numerous benefits for the skin, rice bran oil takes these benefits to the next level, providing a potent, convenient, and versatile solution for maintaining healthy, radiant skin.

For those seeking a natural, effective skincare regimen, rice bran oil represents the evolution of ancient traditions, combining modern science with time-tested wisdom.

How to Safely Use Rice Bran Oil in Skincare

Patch Test. Rice and rice products, including rice bran oil, could cause an allergic reaction. Patch testing helps determine if you have any sensitivities or adverse reactions to the ingredient. In which we recommend you discontinue use. If you suspect an allergy, seek medical attention immediately.

Here are some recipes to try:
