Exceptional products and solutions are available.

Biba Concept Store has been our exclusive retail partner in Portugal since 2020 and has been distributing our skincare brand “siin Edition Edelweiss” with great success. The collaboration has continuously expanded in recent years and we are delighted that Biba Concept Store now also carries our brands “Only What’s Good” and “Nature” exclusively in Portugal.

Partnership with siin

siin stands for high-quality products developed and manufactured in Austria – with a strong commitment to quality, effectiveness, and origin. Our solutions are created in harmony with an intact natural environment, shaped by the Alps, pure air, and fresh spring water, which we consciously integrate into our product development.

Our goal is to make this “Made in Austria” quality accessible worldwide. To achieve this, we are looking for dedicated distribution partners who share our values and want to unlock new potential in dynamic markets together with us. Our focus lies on attractive niche segments where our products can clearly differentiate and establish a sustainable position.

We offer flexible cooperation models – from open trading relationships to exclusive import partnerships in defined markets. Our purchasing conditions are fair and performance-oriented, aligned with market potential and order volumes, creating a true win-win situation for both sides.

Through authentic storytelling around the development, production, and origin of our products, we work together with our partners to build emotional brand worlds that create trust and drive demand.

Together, we bring quality from Austria to the world.

Complementary Innovation – in partnership with Fourme Formulas

siin is expanding its portfolio with selected nutraceuticals from Fourme Formulas – based on a globally unique principle: the combination of psychology and biochemistry, translated into circadian nutrient complexes designed for people exposed to high levels of mental and physical stress.

This partnership is the result of an intensive, interdisciplinary exchange between the experts of both companies. It combines scientific expertise, practical development, and a shared ambition to redefine approaches in health and beauty prevention.

For siin, this step is a natural progression: our philosophy goes far beyond conventional cosmetics. We do not believe in superficial, decorative beauty – but in a holistic understanding of longevity. Beauty that originates from within, evolves over time, and is sustainably supported through targeted physiological balance.

Effective immediately, our distribution program includes the nutrient complexes “balance 4 complex” – available as a 7-week treatment and as a 1-month solution. Starting in May 2026, we will introduce the revolutionary and unique “adolescence complex”, developed for individuals aged 12 and above to support mental stability.

Together with Fourme Formulas, we are creating a new dimension: preventive beauty, scientifically grounded – from the inside out.
