HISTORY
Rice (Oryza sativa) has long been revered in Japan as a symbol of nourishment and purity. For centuries, Japanese women have incorporated rice water and rice bran into their beauty rituals to maintain soft, luminous complexions. Rice bran, the nutrient-dense outer layer of the grain, was particularly valued for its ability to improve skin clarity and smoothness.
With advancements in botanical science, researchers identified Gamma-Oryzanol as a key active compound in rice bran oil responsible for its antioxidant properties. Triple Rice Radiance Complex was developed to concentrate and optimise these traditional benefits by combining defatted rice bran with stabilised Gamma-Oryzanol and rice-derived dextrin, creating a more bio-active and performance-driven ingredient.
SCIENCE
Triple Rice Radiance Complex is effective because each of its three ingredients has a unique benefit for the skin, and together they create a formula that is both gentle and effective. Defatted rice bran comes from the outer layer of the rice grain after the oil is removed. Even without the oil, the bran still contains valuable plant compounds such as proteins, polysaccharides, and antioxidants. Research shows that rice bran contains important phenolic compounds, many of which are naturally found in the bran’s structure. This is one reason rice bran has been used in beauty routines for so long. It helps skin feel smoother and look fresher in a gentle way, without the dryness that stronger exfoliants can cause. For daily skincare users, this means skin can feel cleaner, softer, and more refined, while staying comfortable.
Gamma oryzanol is one of the key ingredients in this complex. It is a natural antioxidant found in rice bran oil and is made up of compounds related to ferulic acid, which is known in skincare for protecting skin from oxidative stress. Oxidative stress happens when skin faces daily challenges like UV rays, pollution, and other environmental factors, which can make skin look dull and tired. Rice bran oil usually contains about 1 to 2 per cent gamma-oryzanol. While this might seem like a small amount, it is actually significant for a natural ingredient. Studies have examined its antioxidant effects and its ability to protect skin in UV exposure tests. Simply put, gamma oryzanol helps skin look brighter, calmer, and less affected by daily stress.
Dextrin might not sound exciting, but it plays an important role in making the complex work well in skincare. Dextrin is a carbohydrate made from starch, and in cosmetics, it is often used to improve texture, reduce heaviness, and help other ingredients spread evenly on the skin. Scientific reviews say dextrin is biodegradable, safe for the body, and effective at delivering ingredients, which means it can make a formula feel smoother and support the stability and performance of other ingredients. For users, this means the product feels smoother, less sticky, and easier to apply, while helping the rice-based ingredients work better.
What makes Triple Rice Radiance Complex especially interesting is that it does not rely on a single hero ingredient. Instead, it combines gentle skin polishing from defatted rice bran, antioxidant protection from gamma oryzanol, and formula support from dextrin. This gives the complex a balanced profile that suits people who want radiance and smoothness without the harshness that can come with stronger acids or aggressive treatments. Rather than forcing the skin to renew rapidly, it supports a softer approach. Skin can gradually look clearer, fresher, and more luminous, while still feeling calm and cared for.
