Manjistha (Rubia cordifolia) powder is a traditional Ayurvedic root extract used in skincare for its purported skin-brightening, antioxidant, and anti-inflammatory properties, often applied in masks for hyperpigmentation and acne. Clinical evidence is largely limited to traditional use and preliminary studies.
