Purodem

Purodem is a UK-based education provider specialising in natural skincare and therapeutic formulation. Founded by aromatherapist, skincare formulator and educator Deana Kassim, who has more than 20 years of experience in the therapy sector, the school teaches students to understand why formulations work, as well as how to make them. Its online programmes serve beginners, skincare brand-builders, complementary therapists and other practitioners.

The Diploma in Natural Skincare Formulation guides learners from first principles through emulsions, gels, anhydrous products and surfactant-based formulations, with training in ingredient functions, product development and good manufacturing practice. The Professional Essential Oil Therapy diploma is an advanced programme focused on essential oil blends, product formulation and therapeutic application. Purodem also offers workshops and continuing professional development training, covering topics such as essential oil safety and responsible practice.

Teaching combines structured modules, tutor support and applied assessment, with attention to dosage, contraindications, stability and preservation. Purodem’s journal shares articles and references on formulation methods and materials.
