Rice water is one of the oldest beauty remedies still in daily use. Women in Heian-era Japan and in parts of China were famous for long, glossy hair kept with rice water, and today it has found new life in toners, cleansers, serums and hair masks. It is gentle, inexpensive and versatile, which is exactly why it has stayed popular for so long. This guide covers what rice water actually does for skin and hair, how to use it correctly, and where a formulated product beats a homemade batch.
You will find it mapped to real options along the way, from the Rice Water Brightening face serum to the wider skincare collection. As a herbal beauty brand, Oshea blends traditional botanicals with modern formulation, which you can read more about here.
1. What Is Rice Water?
Rice water is the cloudy, starchy liquid you get from soaking, rinsing or cooking rice. As the grains sit in water, they release starches, vitamins, minerals and antioxidants into the liquid. That nutrient-rich water is what people apply to skin and hair.
It has a long history in traditional Asian skincare and haircare, and a growing number of modern products now include rice water or rice-derived extracts. It is worth being honest about the science: many benefits are supported by small studies and centuries of anecdotal use rather than large clinical trials, as consumer-health reviews such as this overview of rice water for skin point out. That does not mean it does nothing, only that it is best treated as a gentle supportive ingredient.
Think of rice water as a soft, everyday support step rather than a powerful active. It complements a routine built on proven ingredients like sunscreen, vitamin C and niacinamide.
2. What Is Inside It and How It Works
Rice water carries several compounds that are useful for skin and hair.
The key components
- Inositol: a carbohydrate that is thought to penetrate and help repair the hair shaft, and may support skin elasticity.
- Ferulic acid and allantoin: antioxidants that help neutralise free radicals and soothe irritation.
- Amino acids: the building blocks of protein that support hair strength and skin softness.
- Starch: coats the hair for a smooth, glossy finish and gently exfoliates skin when rinsed off.
- B vitamins and minerals: support a healthy scalp and skin barrier.
According to consumer-health summaries such as this guide to rice water, inositol is the compound most associated with the smoothing and protective effect on hair. Small studies referenced by dermatology writers suggest rice water has antioxidant activity and may support the skin barrier, though larger trials are still needed.
One frequently cited example is older research on rice starch added to bath water, where people whose skin was irritated by a common cleansing agent, and people with atopic eczema, saw improvements in the skin's healing capacity and barrier function. Allantoin, another compound found in rice water, is a well-known soother used in many calming formulas. Together these help explain why rice water tends to feel comforting on the skin rather than active or tingly, which is a big part of its appeal for reactive skin.
3. Types and Forms of Rice Water
There is more than one way to prepare and buy rice water, and the form changes how strong and how gentle it is.
| Form | How it is made | Best for |
|---|---|---|
| Soaked (plain) | Rice soaked in water for 30 minutes, then strained | Sensitive skin, beginners, everyday gentle use |
| Boiled | Water left after cooking rice, diluted | A slightly more concentrated rinse |
| Fermented | Plain rice water left to ferment for a day | A more acidic, antioxidant-rich option |
| Formulated product | Standardised rice extract with preservatives and actives | Consistent, convenient daily use |
Formulated rice water shows up across categories. For skin there is the Rice Water Brightening foaming cleanser and the Rice Water toner. For hair there is the Rice Water nourishing shampoo, the Rice Water conditioner and the Rice Water hair mask. There is even the Rice Water body lotion for all-over softness.

4. Benefits of Rice Water for Skin
On skin, rice water is soothing and supportive rather than dramatic. Here is what it can offer.
Soothes and supports the barrier
Its antioxidants and starches help calm irritation and support the skin barrier, which is why it feels comforting on sensitive or reactive skin.
Light hydration and softness
The amino acids and minerals give a light, non-greasy hydration that leaves skin feeling soft and smooth. Explore the serum collection and the cleanser collection for rice-based options.
Subtle brightening and even tone
Antioxidants like ferulic acid, plus the gentle exfoliating effect of the starch, can give skin a fresher, more even look over time. For a stronger brightening push, rice water pairs well with vitamin C, such as the Vitamin C serum. Browse the full brightening collection and the glow range.
In a small 2018 study referenced by dermatology writers, a rice water gel showed antioxidant activity comparable to vitamin C over 28 days, and a separate inositol study suggested improvements in skin elasticity. These are early, small studies, so results in real life are gentle and gradual.
5. Benefits of Rice Water for Hair
Rice water has its strongest reputation in haircare, and the effects here are usually easier to feel.
Smoothness and shine
The starch coats the hair shaft, smoothing the cuticle so hair detangles more easily and looks glossier.
Strength and reduced breakage
Inositol and amino acids are thought to support the strand and reduce surface friction, which can mean less breakage and split ends over time. See the hair serum collection and the shampoo collection, or add a leave-in like the Phytogain hair serum.
Scalp comfort
Used as a rinse, rice water can leave the scalp feeling balanced and comfortable, especially for those who like a lightweight, natural routine. Explore the hair oil collection for complementary nourishment.
A quick word on expectations: rice water is a finishing, conditioning step rather than a deep repair treatment. It improves how hair looks and feels from the outside, so it works best layered over a solid routine of gentle cleansing, regular conditioning and the occasional deeper mask, not used on its own as a substitute for them.

You can use rice water as a simple homemade rinse or as part of a formulated routine. Both work; the product route is just more consistent.
Homemade rice water, step by step
- Rinse half a cup of uncooked rice to remove surface dust.
- Add two to three cups of clean water and soak for about 30 minutes.
- Strain out the rice and keep the cloudy water.
- For a stronger version, leave it at room temperature for a day to ferment, then refrigerate.
- Store in the fridge and use within two to three days.
If your skin or hair leans sensitive, dilute the first few batches with extra plain water and see how you respond before moving to full strength. Fermented batches in particular are more potent and more acidic, so ease into them rather than starting there.
On skin
Use as a toner after cleansing: sweep it on with a cotton pad or press it in with your hands, then follow with serum and moisturiser. A ready-made option like the Rice Water toner saves the daily preparation.
On hair
After shampooing, pour rice water over the hair and scalp, massage gently, leave for a few minutes, then rinse. Use once or twice a week. If you prefer products, the Rice Water hair mask and toner range make it simple.

7. Fermented vs Plain and Common Cautions
Rice water is gentle, but a few points keep it safe and effective.
- Fermented is stronger: it is more acidic and antioxidant-rich, which suits those wanting a bigger effect, but it can be too much for very sensitive skin.
- Do not overuse on hair: the protein-like compounds can build up and leave some hair feeling stiff or straw-like. Once or twice a week is enough.
- Fresh only: homemade rice water spoils quickly. Keep it refrigerated and discard it after a few days.
- Patch test: as with any new product, test on the inner arm first.
8. How to Choose Rice Water Products
If you would rather not make a fresh batch every few days, a formulated product is the practical choice.
- Match the format to the goal. Toner or serum for skin, shampoo, conditioner or mask for hair.
- Look for supporting ingredients. Vitamin C or brightening botanicals for skin, proteins and conditioning agents for hair.
- Prefer standardised formulas. They are preserved, consistent and free from the spoilage problem of homemade batches.
- Check quality signals. See our awards and certifications page for reassurance on standards.

12. Frequently Asked Questions
What does rice water do for skin?
Rice water contains antioxidants such as ferulic acid and inositol, plus starches and amino acids. Used on skin it can soothe irritation, support the skin barrier, add light hydration and give a mild brightening effect. The evidence is still limited and mostly small studies, so treat it as a gentle, supportive step rather than a strong active.
Is rice water good for hair growth?
Rice water is traditionally used to make hair look smoother, shinier and stronger, and it contains inositol, which is thought to help protect and repair the hair shaft. Strong clinical proof that it grows hair is limited, so it is best seen as a conditioning rinse that improves the look and feel of hair rather than a guaranteed growth treatment.
How do I make rice water at home?
Rinse a half cup of uncooked rice, add it to two to three cups of clean water, and soak for about 30 minutes. Strain out the rice and keep the cloudy water. Store it in the fridge and use it within two to three days. You can also lightly ferment it for a day at room temperature before refrigerating.
Can I use rice water on my face every day?
Rice water is gentle enough for most people to use once daily as a toner or rinse. Start every other day, watch how your skin responds, and increase if it stays comfortable. Always patch test first, and follow with a moisturiser.
How often should I use rice water on my hair?
Once or twice a week is usually enough as a post-shampoo rinse or mask. Because rice water contains protein-like compounds, using it too often can leave some hair types feeling stiff or straw-like, so it is better to use it in moderation and adjust to how your hair feels.
Does rice water brighten skin?
Rice water may give a mild brightening and evening effect thanks to its antioxidants and the way its starch gently exfoliates when rinsed off. It is a subtle, gradual effect rather than a strong lightening action, and it works best alongside daily sunscreen.
Plain or fermented rice water, which is better?
Fermented rice water is more acidic and richer in antioxidants, which some people find more effective, while plain or soaked rice water is milder and gentler. Sensitive skin and beginners may prefer plain rice water, while those wanting a stronger effect can try a short fermentation.
Are rice water products better than homemade rice water?
Homemade rice water is cheap and easy but spoils quickly and varies in strength. Formulated rice water products are standardised, preserved and combined with other supporting ingredients, so they are more consistent and convenient for daily use. Both can work; it comes down to convenience and reliability.
