Skin is the largest organ of the body and reflects inner health and humoral balance. The Unani system identifies four main skin types (Saudawi, Safrawi, Balghami, Damawi) based on qualities like dryness, oiliness and sensitivity. Imbalance can lead to issues like acne, wrinkles or rashes. Factors like stress, diet and environment also impact the skin. A scientific study found a direct link between perceived stress and worsened acne symptoms. The holistic Unani approach considers skin type, lifestyle factors and seasonal changes to maintain skin health and treat issues.
