A woman's body is greatly influenced by age and the balance of female hormones. As life stages transition—sexual maturity (pregnancy, childbirth), menopause, and old age—the concerns^*1 surrounding the body also change.
When you unconsciously adapt to a busy daily life and then suddenly pause, you notice a physical discomfort^*2.

To achieve the future each individual desires, we want to consider an approach that "addresses the foundation^*3" through new self-care, rather than simply "reacting to what has occurred."
KNOWYOUR products began development with this vision.

The "ideal self" you envision is not a distant goal, but something that exists within you now.
Carefully nurturing and fulfilling the beauty dormant within your core, and leading you to confidence—that is our concept of self-care.
At KNOWYOUR, we focus on our origin—the 37 trillion cells that make us up. We have refined our ingredients and quality for you, who live authentically and flexibly.

Making the radiance nurtured by accumulated time even deeper and more certain.

*2: Changes associated with the issues in *1.
*3: Refers to the stratum corneum.

KNOWYOUR focuses on the remarkable beauty ingredient "human stem cell conditioned medium^*5." We use undiluted "human stem cell conditioned medium^*5," which is rich in components that maintain healthy skin.

Furthermore, by encapsulating the undiluted "human stem cell conditioned medium^*5" in liposomes, we stabilize the ingredients, allowing them to be delivered more deeply^*4 in a fresh state.

Because it's something you apply to your body, we are particular about our raw materials.

KNOWYOUR products are manufactured in a "GMP-certified factory" that has acquired ISO22716, an international standard for manufacturing quality. They are an "additive-free formulation" with approximately 97% naturally derived ingredients, free from methylparaben, phenoxyethanol, ethanol, mineral oil, heavy metals, synthetic fragrances, synthetic colorants, silicones, and UV dispersants.

For the core "human stem cell conditioned medium," we use only the supernatant (conditioned medium) extracted during the process of culturing human stem cells, which are said to be less likely to cause rejection or foreign body reactions in the body. This is derived from tissues collected from donors at collaborating obstetrics and gynecology clinics.
We conduct four screenings^*6 on the donor and the cells during the culture process to check for contamination by viruses or other agents.

*6: Infectious disease screening items: Tests for infections and toxicity such as HBV (Hepatitis B), HCV (Hepatitis C), Syphilis, HIV, CMV, HTLV-1, PVB19, and EBV.
