Welcome to Purodem®
Online training in natural skincare and therapeutic formulation, for skincare brand-builders, complementary therapists, and anyone who wants to learn it from the ground up.
Purodem is, at heart, a school of formulation. Everything taught here comes back to one skill: taking plant-based ingredients and bringing them together into something safe, stable, and genuinely useful.
That skill leads in two directions. Some students are here for cosmetic formulation, learning to create skincare for themselves, for clients, or for a brand they’re building. Others are here for therapeutic formulation, using essential oils, vegetable oils, hydrolats, and plant actives to build products around a person’s wellbeing needs. The underlying craft is the same, which is why both live comfortably under one roof.
Whichever direction you’re heading, the teaching is built from the ground up, ingredient by ingredient, principle by principle, so the why always comes alongside the how.
Purodem offers two qualifications, each one a full course in its own right, and a natural starting point depending on where your interest lies.
Learn to formulate for an individual client, from the consultation through to a product where you can justify every decision.
This is a two-stage qualification, a Level 3 Foundation Award and a Level 4 Diploma, that takes you from first principles through to independent practice with clients. You’ll work across the full therapeutic palette (essential oils, vegetable oils, hydrolats, plant extracts, and functional ingredients) and four formulation bases, building real skill in applied anatomy and physiology, safety reasoning, consultation and client records, and formulation decisions you can defend.
It suits anyone bringing formulation into a practice they already have, building a therapeutic practice from scratch, or wanting to work with a wider palette than essential oils alone.
At a glance:
Learn to create skincare that is safe, stable, and effective, and to understand the choices behind every formulation you make.
This is a genuinely beginner-friendly diploma that takes you from first principles through to confident, independent formulation. You’ll work across the core cosmetic systems (emulsions, anhydrous formulations, gels, and surfactant-based products), building real technical skill in ingredient function, formulation structure, good manufacturing practice, and systematic product development.
It suits anyone formulating for themselves, developing a product range, or building a skincare brand on solid ground.
At a glance:
Join the Purodem mailing list and Deana will show you around the school: what we teach across natural skincare and therapeutic formulation, and a few of the Journal pieces readers find most useful.
After that, there’s no newsletter schedule to fill. You’ll hear from her when there’s something worth reading, or when enrolment opens on one of the courses.
We’ll send a short email asking you to confirm. No spam, and you can unsubscribe at any time.
Every Purodem programme is built around the same idea: that you learn formulation best when the teaching is structured, when there’s someone to ask, and when what you make actually has to work.
In practice, that means:
Our students come from all kinds of backgrounds: complementary therapists, nurses and healthcare professionals, skincare formulators, and people who simply wanted to take their interest further.
The Journal is where we think out loud about formulation: the materials, the methods, and the reasoning behind a product that is safe, stable, and genuinely useful. Articles and references for practitioners, students, and formulators who want to understand the reasoning behind the method.
