Formulation and Evaluation of Alum Toner Spray for Anti-Acne Activity

Alum, also known as fitkari, is a naturally occurring compound that has been recognized for its role in skin health. It assists in lightening dark spots, minimizing scars, and reducing fine lines due to its astringent and antibacterial properties. Transdermal sprays (TS) have emerged as a superior alternative to traditional transdermal drug delivery systems because of enhanced safety and user compliance. The increasing global demand for multifunctional skincare products with minimal side effects underscores the relevance of innovative ingredients such as alum. Chemically, alum is denoted as KAl(SO4)₂·12H2O and comprises key elements like potassium, aluminium, and sulfate. Its diverse applications range from skincare to medicinal and industrial use. This research highlights the formulation of an alum-based toner spray and evaluates its physicochemical and dermatological properties.
