Korean Rice Water for Glass Skin: Does It Really Work? Dermatologist Answers

Korean skincare hacks have undoubtedly taken over the world. One such traditional K-beauty hack is that of rice water. This has taken social media by storm. Korean rice water is packed with vitamins and amino acids, and it promises to brighten skin tone and give a smooth, glass skin finish. But are these promises scientifically backed or just a fad? Today, we will answer this for you.

To understand this better, we reached out to Dr Ruben Bhasin Passi, Senior Consultant, Dermatology, CK Birla Hospital, Gurgaon.

What is The Korean Rice Water Skincare Hack?

Dr Passi says that rice water has become one of the most talked-about ingredients in the world of ‘natural’ skincare. The expert says it  is credited on social media with everything from brightening dull skin to shrinking pores overnight. “The claim traces back to traditional Korean and Japanese beauty practices, where rice water was used for centuries. But dermatologists suggest the modern version of this trend deserves a closer, more critical look,” she adds.

So what does rice water actually contain? Dr Passi answers, “Rice water is simply the starchy liquid left behind after soaking or rinsing rice. It contains small amounts of vitamins, minerals and antioxidants, along with starch and amino acids. These components are not without benefit, but the concentrations found in a home-made batch are far lower than those found in formulated skincare products designed to deliver active ingredients efficiently.”

Korean Rice Water: Does It Really Work?

Dr Passi says that the most common myth related to Korean rice water is that it can dramatically transform skin texture or tone within days, as many viral videos suggest. Is it a myth or reality? Answering this, she says, “Dermatologists are clear that visible, lasting changes in skin brightness or pore appearance require consistent, targeted treatment over weeks, not a splash of starchy liquid applied once or twice. Any immediate ‘glow’ effect from this hack is more likely due to a mild, temporary tightening from the starch rather than a genuine change in skin health.”

So where can it genuinely help? Dr Passi explains, “Rice water is not without merit. Its mild antioxidant content and soothing properties can offer a gentle boost for sensitive or dry skin, and as a light toner, it is unlikely to cause harm for most skin types. It may also feel pleasantly refreshing as part of a simple routine.”

Are There Any Risks of Korean Rice Water for Skin? 

Shedding light on whether it has any risk, Dr Passi says that the main concern lies in hygiene. “Home-made rice water, if not stored or prepared properly, can develop bacterial growth within a day or two, particularly in warm, humid climates. Applying a contaminated solution to the face can trigger breakouts or irritation rather than prevent them. There is also no regulation or consistency in home preparation, meaning results vary widely from batch to batch.”

So what is the ideal recommendation? The expert answers, “Rice water can sit comfortably alongside — never in place of — a proper skincare routine that includes cleansing, moisturising and sun protection. Freshly made batches, used within a day and stored in the refrigerator, are the safest approach.”

What Study Says About Korean Rice Water in Skincare

A 2025 study, published in the journal Cosmetic, examined the popular Korean skincare hack of using rice water to understand if it actually delivers on its promises of glowing, glass-like skin. The researchers studied the biochemical makeup of rice water to see exactly what active ingredients are released during the soaking or fermenting process. They found out that rice water is incredibly rich in amino acids, vitamins, and minerals. All of these are essential for maintaining a strong and healthy skin barrier. 

One of the important part of the findings is that rice water contains powerful antioxidants such as ferulic acid and phytic acid. This protects the skin from environmental damage and premature ageing. The research confirmed that these natural compounds actively brightens the complexion and fade dark spots. They do so by gently inhibiting excess melanin production. 

Moreover, the starchy nature of rice water acts as a natural soothing agent. This significantly reduces redness, inflammation, and irritation in sensitive skin types. The researchers added that fermented rice water gives even better results. This is because the fermentation process creates beneficial probiotics and breaks down nutrients, so they can penetrate the skin more deeply. 

When applied topically, this nutrient-dense liquid can boost skin hydration, elasticity, and provide a smoother skin texture. While it is not a magical overnight cure for severe dermatological conditions, the science strongly states that it can be used as a gentle, skin-enhancing toner. The study concluded that the viral Korean rice water hack is indeed a highly effective, scientifically backed, and affordable method for a brighter and healthier complexion.
