Paeonol (INCI: Paeonol) is a white to off-white crystalline powder known for its strong tyrosinase-inhibiting activity, helping brighten and even skin tone. It also provides notable anti-inflammatory and antibacterial benefits (MIC 62.5 mg/mL), making it useful for soothing irritation, reducing redness, and improving blemish-prone skin.

With good solubility in alcohol and oils, Paeonol can be easily incorporated into serums, creams, and gel systems. It is typically used at 0.01–0.2%, delivering effective skin-calming and brightening performance while maintaining formulation stability.
