"It was all great, but Asha was a stand out. She is just incredible - I could listen to her alllll day!

I loved the panel at the end too - I learn so much listening to other people’s questions"

"Last year was amazing - I attended in person and nothing trumps that. The connection, the vibe of the room, meeting so many fellow skin nerds and industry superstars… This year (2026) I attended virtually and I am so so grateful for the option! Being rural WA based, I know better than most about industry events so often being out of reach. This conference has been INCREDIBLE! I can’t recommend it highly enough for anyone in our industry with a focus on skin health - Corneotherapist or not."

Mastering Barrier Function and Hormonal Pigmentation


Deepen your clinical expertise with 4 hours of advanced, holistic skin education focused on Barrier Disordered Skin and Hormonal Pigmentation — two complex conditions that often leave even experienced skin therapists feeling uncertain about how to proceed.

In the Barrier Disordered Skin Masterclass, you’ll extend your knowledge of the skin’s three Barrier Defence Systems — the Microbiome, the Acid Mantle, and the Stratum Corneum. You'll explore the role, formation, damage, and repair mechanisms of each system, and deepen your understanding of the skin’s Adaptive and Innate Immune Systems and how they influence reactions and healing responses. You'll also connect the dots between internal health and skin resilience through the Hierarchy of Internal Needs, covering digestion and nutrition, the nervous system, immune function, detoxification, and hormonal balance.

In the Hormonal Pigmentation Masterclass, you’ll advance your understanding of melanogenesis, building a clear knowledge of how pigment is created, how hormonal pigmentation differs from traditional pigmentation, and what this means for your clinical approach. You’ll thoroughly explore internal health triggers linked to hormonal pigmentation and learn how to design safe, effective treatment strategies that address the root cause of your client’s concerns. Solutions are covered in depth, offering tried and tested approaches to managing hormonal pigmentation successfully.
