As the weather cools down, your skin needs a little extra support.
Colder months can mean increased dryness, dehydration, sensitivity and a compromised skin barrier, making a consistent home care routine more important than ever.
Our daily winter skincare essentials:
• Gentle cleanser
• Hydrating serum
• Moisturiser tailored to your skin
• SPF every single day
At DBJ, we’re big believers in Dermaviduals. Their customised, corneotherapy-based approach helps support skin barrier function while delivering exactly what your skin needs throughout the changing seasons.

As I make my way home from Taiwan, I’m feeling incredibly grateful for what has been such a special and memorable few days.
Being invited to learn from Dr Mauricio de Maio and spend time with so many talented professionals from across Australia was a privilege I don’t take lightly. The education was exceptional, but what has stayed with me most is the experience itself, the conversations, the connections and the wonderful people I had the opportunity to meet along the way.
There was a moment during the trip where I found myself feeling quite emotional. Not because of anything in particular, but simply because I felt so grateful to be there, surrounded by inspiring people and learning from some of the very best in our industry.
To Allergan and everyone involved in making this experience possible, thank you. Opportunities like this are incredibly special, and I’m so appreciative to have been part of it.
I’m returning home feeling inspired, excited and even more passionate about what I do. I can’t wait to bring these learnings back to Define by Jill and continue delivering thoughtful, personalised care to every patient who trusts us with their journey.
Moments like these remind me how much I love this industry, how much there is to learn and how grateful I am to do what I do every day.
