Rice washing water
There is a belief that washing the face with rice water can lead to skin whitening.
Is this true?

Dr. Huang Ruiyun reply Dermatology
Cleansing water or facial cleansers have a short contact time on the skin, resulting in limited whitening effects.
After washing the face, the stratum corneum's moisture content increases, making the skin appear whiter, but this effect is temporary.

More Info
The idea that rice water can brighten the skin is a popular belief, particularly in various cultures where rice is a staple food. However, the scientific evidence supporting this claim is limited. Rice water is the starchy water left over after soaking or boiling rice, and it contains vitamins, minerals, and antioxidants that can be beneficial for the skin. Some proponents suggest that it can help improve skin texture, reduce inflammation, and even brighten the complexion. However, the effects are often overstated.
When you wash your face with rice water, the immediate effect may give the appearance of brighter skin due to the hydration it provides. After cleansing, the skin's outer layer may temporarily appear more luminous because of increased moisture content. However, this effect is short-lived and does not equate to a permanent change in skin tone or brightness. The skin's natural color is primarily determined by genetics and melanin production, and while certain ingredients can help improve skin health, they cannot fundamentally alter skin pigmentation.
Moreover, the application of any topical substance, including rice water, typically results in very brief contact with the skin. The effectiveness of a product often depends on how long it remains on the skin and its ability to penetrate the skin barrier. In the case of rice water, while it may provide some hydration and nutrients, the transient nature of its application limits its potential for significant skin brightening.
In terms of skin health, it is essential to focus on a comprehensive skincare routine that includes sun protection, hydration, and the use of products that contain proven active ingredients. For instance, ingredients like vitamin C, niacinamide, and alpha arbutin have been shown to have more substantial effects on skin brightening and evening out skin tone. Additionally, regular use of sunscreen is crucial, as UV exposure can lead to skin darkening and pigmentation issues.
In summary, while rice water may offer some benefits for skin hydration and texture, it is unlikely to produce significant or lasting skin brightening effects. If you are looking for ways to improve your skin's appearance, consider incorporating a well-rounded skincare routine that includes sun protection and scientifically-backed ingredients. Always consult with a dermatologist for personalized advice and treatment options tailored to your skin type and concerns.
