Rice Water for Skin: Is It Safe to Store and Use Homemade Rice Water for Several Days?

Rice water has become a popular home remedy for skincare, with many people using it as a toner, facial rinse, or refreshing mist. Made by soaking or boiling rice in water, this simple preparation is often associated with softer skin, a brighter complexion, and a smoother appearance. However, while making rice water at home is easy, storing it for several days raises an important question: is it still safe to apply to your face?

Unlike commercially manufactured skincare products, homemade rice water usually contains no preservatives. This makes it more vulnerable to microbial growth, particularly when stored at room temperature or handled without proper hygiene. Here is what you should know before adding rice water to your skincare routine, as per Dr Kiran Gupta, Professor at Mewar University and Senior Physician at the Naturopathy Hospital in Jaipur.

What Are the Benefits of Rice Water for Skin?

According to a study published in the journal ‘Cosmetics’, rice water contains starch and small amounts of other rice-derived compounds. Depending on how it is prepared, it may also contain sugars, amino acids, and other substances released from the rice.

Some people use rice water to make their skin feel softer and smoother. Its starch content may leave a temporary film on the skin, creating a smoother feel. However, scientific evidence supporting many of the popular claims about rice water remains limited.

Here are some commonly reported uses:

• Temporary soothing effect: Rice water may feel soothing on the skin, although it is not a proven treatment for inflammatory skin conditions.
• Smoother appearance: Starch may leave a light coating that makes the skin feel temporarily smoother.
• A refreshing rinse: Some people use it as a simple addition to their skincare routine.
• Skin brightening claims: Rice-derived ingredients are used in some skincare products, but there is insufficient evidence that homemade rice water reliably fades pigmentation, removes dark spots, or produces a lasting brightening effect.

Rice water should not be considered a replacement for sunscreen, moisturiser, or treatments recommended by a dermatologist.

Is It Safe to Store Homemade Rice Water for Several Days?

According to a study published in the journal ‘Processes’, homemade rice water is best prepared fresh rather than stored for several days. It can become contaminated with bacteria, yeasts, or mould, particularly if it is left at room temperature, stored in an unclean container, or repeatedly touched during use.

Rice water provides moisture for skin and may contain nutrients that support microbial growth. Once prepared, it does not have the preservation system used in many commercial skincare products to control contamination.

Refrigeration can slow microbial growth, but it does not sterilise rice water or prevent all microorganisms from multiplying. Even if the liquid looks clear and smells normal, it may not be free from harmful microbes.

There is no universally established, evidence-based storage period that guarantees the safety of homemade rice water for facial application. Therefore, using a fresh batch is the more cautious approach, particularly for people with sensitive or acne-prone skin.

How Long Can You Keep Rice Water?

The safest approach is to prepare only the quantity you need for one application and discard the remainder.

If you choose to prepare rice water in advance, keep the following precautions in mind:

• At room temperature: Avoid leaving homemade rice water out for prolonged periods, particularly in warm or humid conditions.
• In the refrigerator: Cooling may slow microbial growth, but it does not guarantee safety. There is no validated storage duration for homemade rice water intended for skincare.
• In the freezer: Freezing may slow or stop microbial growth while the water remains frozen, but it does not reliably kill all microorganisms. Thawing and handling can introduce further contamination.

Do not rely on a fixed number of days to decide whether a batch is safe. Discard it if it develops an unusual smell, changes colour, becomes unexpectedly slimy, or shows signs of mould.

However, remember that contamination may occur without visible changes.

How to Make Fresh Rice Water at Home

Making a small batch is simple and reduces the need for prolonged storage.

What you need:

• Two tablespoons of plain rice
• A small bowl of clean water
• A clean bowl or container

Method:

• Rinse the rice to remove surface dirt and loose particles.
• Place it in a clean bowl and add fresh drinking water.
• Let it soak for around 15-30 minutes, stirring gently.
• Strain the water into a clean container.
• Use a small amount immediately and discard the remaining liquid.

You can also prepare rice water by boiling rice in water and allowing the liquid to cool. However, boiling does not guarantee that the final preparation will remain free from contamination, particularly after cooling and handling.

Avoid adding lemon juice, essential oils, or other kitchen ingredients to extend its shelf life. These additions do not provide reliable preservation and may irritate the skin.

How to Use Rice Water Safely on Your Face

Even freshly prepared rice water may not suit everyone. Follow these precautions before using it regularly:

• Do a patch test: Apply a small amount to a limited area of skin and monitor it for irritation over the next 24-48 hours.
• Use clean hands and containers: Avoid dipping fingers into the preparation repeatedly.
• Avoid broken skin: Do not apply homemade rice water to cuts, open wounds, or severely irritated areas.
• Keep it away from your eyes: If it enters your eyes, rinse thoroughly with clean water.
• Stop if irritation develops: Redness, itching, burning, or swelling are reasons to discontinue use.

People with eczema, a damaged skin barrier, or a history of contact allergies should be particularly cautious with homemade preparations. A patch test can reduce uncertainty but cannot guarantee that a product will not cause a reaction.

Can Rice Water Cause Pimples or Skin Infections?

Rice water does not cause acne in everyone, but its effects can vary depending on skin type, preparation, and hygiene. Residue left on the skin may not suit every individual, while contaminated rice water can potentially cause irritation or infection.

If you notice new breakouts, itching, redness or a rash after using it, stop applying it. Seek medical advice if symptoms persist, worsen, or include increasing pain, swelling, or pus.

People with persistent acne, pigmentation or other skin concerns may benefit more from evidence-based skincare products than from relying on homemade remedies.

Should You Use Homemade Rice Water Every Day?

Daily use is not necessary, and there is limited clinical evidence to establish an ideal frequency for applying homemade rice water. If you choose to try it, use a freshly prepared batch, observe how your skin responds, and discontinue it if irritation occurs.

For everyday skincare, a gentle cleanser, a suitable moisturiser, and broad-spectrum sunscreen with SPF 30 or higher are more reliable essentials. If your concern is persistent pigmentation, acne or inflammation, consult a dermatologist for suitable treatment.

Final Word

Rice water may be a simple addition to your skincare routine, but its benefits are not well established. Since homemade preparations lack validated preservation, prepare small quantities, use them fresh and avoid storing them for several days. When it comes to skincare, cleanliness and a healthy skin barrier matter more than following a popular home remedy.
