Women of Longevity

Refugium Refugium

Health and vitality are not a matter of luck.

But a conscious decision.
Yet true change does not arise from knowledge alone – but through experience, exchange, and tangible insights.
At the “Women of Longevity” retreat, you can expect five days with a lasting impact:
featuring leading female experts, well-founded lectures, the latest longevity approaches, practical self-assessments – and space for what is often neglected in everyday life: me-time, reflection, and conversations among like-minded women.
The next retreat will take place from November 9 to 13, 2025.
If you would like to join, please send us your inquiry now.
Places are limited. The impact is not.

Her journey began in competitive sports, where she discovered the importance of body awareness, movement, and regeneration early on as a competitive dancer. In her search for innovative approaches, her path led her from fascia work to the lymphatic system – and thus to a new understanding of holistic health, natural beauty, and inner balance. Today, she is considered a pioneer in the field of lymphatic beauty and wellbeing in German-speaking countries. She opened the first studios for Brazilian lymphatic drainage, developed the ILUMAA EFFECT – a unique shaping method – and her own product line with highly concentrated, deeply effective formulations that specifically support lymph flow through natural ingredients. With her beauty brand ILUMAA LYMPHATIC, she wants to show how essential the lymphatic system is for natural radiance and lasting well-being – and how the “Lymphatic Effect” can be easily and intuitively integrated into everyday life.

‘Women of Longevity’ retreat from 10-14 November 2024

From 10-14 November 2024, the Krallerhof was filled with an extraordinary energy! A group of impressive women came together to discover new perspectives on a long, healthy and fulfilling life. We were deeply touched and motivated by the unique atmosphere created by this community. Together we not only learnt, but also laughed, exchanged ideas and strengthened each other. Special thanks go to Kristine Zeller, Dr Kati Ernst, Sukkhadas Ingo Auer and Simone Kumhofer for the lectures and workshops, as well as to our strong partners Botanicals ®, NOOSHA, OMNi-BiOTiC® and MICALÉ VISIONS, who spoilt our participants with goodie bags!
