Professional, tutor-supported training in Integrative Therapeutic Formulation and natural skincare formulation, taught online from first principles.
Purodem is a school of formulation. We teach the craft from first principles and apply it in two directions: therapeutic formulation, designing products as a considered response to an individual’s wellbeing needs, and cosmetic formulation, creating natural skincare products for personal use, for clients, or for a brand of your own.
Every course is delivered online, with personalised tutor feedback and a strong grounding in ingredient knowledge, formulation method, safety, and applied practice. Whichever direction you choose, you learn why a formulation works, so you can design your own with confidence.
We offer two qualifications, each built on the same formulation foundations and suited to a different professional direction.
Integrative Therapeutic Formulation is the design of non-medical topical and olfactory products as a structured, holistic response to a person’s wellbeing needs. It brings essential oils, vegetable oils, hydrolats, and plant actives together as one connected palette, and it begins with the person: their needs, sensitivities, and circumstances, reasoned through to a formulation made for them.
The qualification is taught at two levels. The Level 3 Foundation Award in Integrative Therapeutic Formulation covers the reasoning, the materials, and the making. The Level 4 Diploma in Integrative Therapeutic Formulation takes you to practitioner level, with supervised casework with real clients and a Client Formulation Plan for every person you formulate for.
It is designed for therapists, complementary and holistic practitioners, health and care professionals, and experienced formulators who want to work with plant materials therapeutically, with structure and depth.
Key features:
The Diploma in Natural Skincare Formulation is designed for anyone who wants to create professional natural and organic skincare products, from complete beginners to aspiring brand founders.
The course teaches formulation from first principles, so you understand how ingredients function, how products are structured, and how to create safe, stable, and effective formulations. You work across the four core product systems used in commercial skincare: creams, gels, balms and butters, and surfactant-based cleansers, building a portfolio of your own range as you go.
Key features:
Our Professional Essential Oil Therapy diploma centres on the therapeutic use of essential oils and bespoke blend formulation for complementary therapists. If the therapeutic use of plant materials is your interest, Integrative Therapeutic Formulation sets essential oils within the wider plant palette and is where most practitioners now begin.
All of Purodem’s training is grounded in clear formulation principles, applied plant knowledge, and high professional standards. Each course builds step by step, combining theory with practical formulation tasks, so you apply what you learn as you go.
You are supported throughout with structured materials, guided tutorials, and personalised feedback on your work, and every course ends with a documented body of work that reflects what you can do. The skills carry across disciplines: formulation method, ingredient selection, safety, and responsible practice.
Our courses are created by Deana Kassim, Purodem’s founder and Lead Educator, an aromatherapist, formulator, and educator with over twenty years in the therapy sector.
If you work with people as a therapist, practitioner, or health or care professional, and want to formulate for the individual in front of you, Integrative Therapeutic Formulation is the course to look at first. If you already hold a relevant qualification or have substantial formulating experience, you may be able to begin at Level 4.
If you want to create natural skincare products, for yourself or to build a brand, the Diploma in Natural Skincare Formulation is the natural starting point, whether or not you have formulated before.
