About Us

Nature Knows. And we know it well.

Since I was a little girl, I remember watching nature — listening, reading, learning about herbs and their beneficial properties. The search for natural yet effective products, my love for nature and our family tradition led me to create my own blends — first as "Kyriaki's Herb Garden" and today with SIOR "Nature Knows", whose products are made in a licensed cosmetics laboratory.

I was born and raised in Chalkida, where I live with my family. With more than 20 years of experience in the handmade preparation of natural cosmetics, every SIOR product carries knowledge, care and consistency.

Studies & Training

My knowledge keeps growing through continuous training: Holistic Herbal Therapy, Natural & Complementary Therapies, Aesthetic Acupuncture, and studies in health and lifestyle.

From handmade to professional production

The love and experience of so many years wanted to take the next step. I wanted my products to reach even more people, with the highest standards of quality and safety. That is how SIOR "Nature Knows" was born: formulas made in a licensed laboratory with official notification on the EU cosmetics portal (CPNP), while keeping the philosophy I started with fully intact — carefully selected botanical ingredients and respect for the skin and for nature.

A family affair

SIOR is not just a business — it is a family. By my side every day are my four children, who share the same vision:

Maria and Zacharoula, professional beauticians, who look after the quality of every skincare experience,

Leontios, in communication and sales, who brings SIOR closer to you,

and Irini Chrysovalantou, the youngest of the family, who is growing up alongside the brand.

It was never just creams on a shelf. It is our daily care, a habit passed down from generation to generation.

Our commitment

Our products capture the scents and richness of the herbs that Greek flora so generously offers — and we are happy to share them in Greece and beyond.

Every product is made in a licensed laboratory to high standards of quality and safety, following a special process that respects the character of the formulas we have been developing for more than two decades.

Every jar is a promise! Thank you for allowing me to keep it!
