Eos is the Greek goddess of the dawn. She rises each morning from her home at the edge of the Oceanus to bring light to the world.

EOS stands for Evolution of Smooth. This reflects the brand's goal to create innovative and enjoyable personal care products that leave skin feeling soft and healthy.

In a medical context, EOS may refer to eosinophils, a type of white blood cell. It can also refer to an EOS imaging system, a low-dose radiation imaging technology used for skeletal assessments.

EOS does not typically offer a membership program. If you are referring to a subscription for EOS products, you can usually manage or cancel it through your online account on the retailer's website where you purchased the subscription, or by contacting their customer service directly.
