Your evening ritual, refined.

The dermaviduals Base Cream delivers intelligent, skin-identical care to replenish hydration and support the skin barrier while you sleep.

A beautifully minimal formula, designed to work with your skin rather than overwhelm it. Because luxury skincare is knowing exactly what your skin needs.

Available in clinic at Define by Jill.

Supporting something bigger than ourselves.

Define by Jill is proud to support Pink Finss, a local Hawkesbury charity dedicated to helping women, men and their families navigate cancer diagnosis, treatment and life beyond cancer.

Through information, connection, support groups and practical services, Pink Finss provides a place where people don’t have to navigate their journey alone.

For us, supporting Pink Finss is about more than sponsorship. It’s about supporting the community we are part of and helping ensure meaningful support remains available when people need it most.

If you’d like to support their work, donations can be made directly through the Pink Finss website.

Support local. Give generously. Make a difference.

Revisiting the incredible Beyond the Barrier Conference, hosted at the W Sydney.

It was so special to see the exact equipment and skincare we use here at Define by Jill, while discovering new ways we can incorporate these technologies and products into our treatments and continue elevating the way we care for our patients.

Once again, an incredible day of learning, innovation and inspiration.
