As Konstantina often reminds her team and customers, to move forward, we must first look back—to our roots and the wisdom of our ancestors. Ancient Greek philosophy and botany reveal profound truths about nature’s hidden values and its capacity to heal, inspire, and sustain life. The teachings of Theophrastus emphasized the deep connection between humanity and the plant world, while Hippocrates highlighted nature’s role as the ultimate source of wellness. By embracing this ancestral knowledge and respecting the gifts of Mother Earth, we cultivate a freer, more spiritually enriched existence while leaving a legacy of care and responsibility for future generations.

A graduate of Purdue University with a Bachelor’s in Chemistry and a Master’s in Engineering, Konstantina has dedicated her life to advancing the art and science of cosmetics. Her certifications in Six Sigma, HACCP, and food microbiology further emphasize her expertise in creating products that combine precision, safety, and efficacy.

Guided by her admiration for ancient Greek ideals and her vision for a sustainable future, Konstantina ensures that DEOS CO. is more than a brand—it’s a movement towards responsible beauty. DEOS CO. celebrates the harmony between nature and innovation, offering customers products they can trust to enhance their well-being, protect the planet, and honor the sacred connection we share with the natural world.
