Glyceryl stearate is a versatile ingredient commonly used in cosmetics and food products for its emulsifying properties. However, a fundamental chemical distinction exists: while it is derived from a fatty acid, it is not a fatty acid itself.

According to cosmetics experts, glyceryl stearate citrate is a versatile and plant-derived ingredient widely used in cosmetic and personal care products for its multifaceted role. So, what does glyceryl stearate citrate do exactly? It primarily functions as an emulsifier, a stabilizing agent, and an emollient, which profoundly impacts the texture, consistency, and hydrating properties of skincare formulas.

A popular misconception suggests that rice is inherently full of kojic acid, a powerful skin brightener. However, kojic acid is actually a byproduct of the fungal fermentation process involving rice and is not naturally present in the raw grain.

According to dermatological studies, topical application delivers potent vitamins to the skin's living layers far more effectively than oral supplements for many specific skin concerns, resulting in targeted improvements in skin health.
