Rice starch is a finely ground powder made from the starch of rice grains. It has become a popular ingredient in skincare products due to its oil-absorbing properties, making it a popular choice for oily and acne-prone skin types. Rice starch is also rich in vitamins and minerals, including B vitamins and magnesium, that can help to soothe and nourish the skin. Additionally, it has been shown to have anti-inflammatory effects, making it useful for reducing redness and swelling in the skin. Rice starch is often used in face powders, cleansers, and masks to help control oil production and provide a matte finish. It is also commonly used as a thickening agent in skincare products, improving their texture and consistency. However, it is important to be cautious when using skincare products containing rice starch, as some people may be sensitive to the ingredient. Overall, rice starch is a versatile and effective ingredient for improving the appearance and health of skin.
"The effect of rice starch on the skin barrier: A randomized, single-blind, controlled clinical trial" by Park et al., published in the Journal of Cosmetic Dermatology (2017).
In this study, the researchers found that topical application of rice starch improved the skin barrier function, decreased transepidermal water loss, and increased hydration in subjects with sensitive skin.
"Rice starch-based cosmetic products improve skin hydration and elasticity: a randomized, double-blind, placebo-controlled clinical study" by Lee et al., published in the Journal of Cosmetic Dermatology (2015).
This study showed that the use of rice starch-based cosmetic products improved skin hydration and elasticity, while also reducing the appearance of fine lines and wrinkles in subjects with dry skin.
These studies provide evidence of the potential benefits of Rice Starch in skin care, and highlight its potential to improve skin hydration, barrier function, and overall appearance. However, more research is needed to fully understand the effects of Rice Starch on the skin, and how it can be used effectively in skincare products.
