A simple vision: skincare products worthy of cult level obsession
Founded by industry veterans Mark, Tracey, and Caoimhe — with over 30 years of experience — our brand was built on a simple vision: to create skincare products worthy of cult-level obsession.
Each formula is developed in-house by our co-founder and cosmetic chemist, using active ingredients at effective, evidence-based levels to deliver real, visible change. No fear. No false promises. Just results.
With luxurious textures, beautiful scents, and formulas designed to make consistency effortless, every product transforms daily skincare into a ritual. Driven by innovation, sustainability, and transparency, our results-focused approach ensures customers not only see the difference — they feel it.
The Doctrine
Products Must Work
Efficacy is the baseline.
We create skincare that delivers visible results.
Led By Expertise
Formulated in-house by a cosmetic chemist.
Every decision is grounded in skin science and chemistry.
Every Ingredient Earns Its Place
Nothing is added for story alone. Actives are included at effective, evidence-based levels.Each ingredient serves performance, experience - or both.
A Ritual Worth Returning To
Results matter. So does pleasure. Texture. Scent. Feel.
Skincare should be something you look forward to, not something you endure.
Knowledge Over Fear
Skincare is one of the most highly regulated consumer categories. Ingredients used within established limits are safe. We do not sell through fear. We believe in informed choice, grounded in expertise.
Buy Less. Choose Better.
True sustainability is choosing with intention.
Buy what works.
Use it completely.
Return to it with confidence.

Tracey Ryan
Co- Founder & Head Of R&D
Hey there! Tracey here, heading up R&D and product formulation at Doctrine. My journey into skincare kicked off with a love for plant-based solutions, leading me to launch my first skincare venture post my Herbal Science degree. In my 12-year stint, I've added a Diploma in Cosmetic Chemistry and various other qualifications, always hungry for more in this ever-evolving industry.
Being a dedicated environmentalist, sustainability is more than a checkbox—it's a genuine commitment. Skincare formulation might be a science, but I also treat it as an art, aiming for products that are not just scientifically sound but also beautiful, sustainable, and effective
Mark O'Sullivan

Caoimhe Donoghue
Co-Founder & Head Of Marketing
Hey, I'm Caoimhe—unapologetically obsessed with skincare. There was a time when I considered a face wipe a solid routine, but oh, how things have changed. Diving into skincare and learning about ingredients got me hooked. Having worked in the skincare industry for a number of years, I gained valuable insights. Skincare doesn't need to be complicated, but unfortunately, many brands make it so.
As the head of e-commerce and marketing at Doctrine, transparency is my focus. We have no time for confusing language, greenwashing, or scare tactics. It's essential to me that our community knows precisely what they're putting on their skin and why.
