Excellent water retention
equipped
Hyaluronic acid has high viscosity (sticky properties) and elasticity (the ability to return to its original shape), and is excellent at holding water.
One gram can produce as much water as six liters
It has the power to retain.

Hyaluronic acid in the body
It decreases with age.
The number of people with this age group peaks in their 20s and then steadily declines.
The number of people in their 20s is the peak and then decreases.

The function of hyaluronic acid
Hyaluronic acid
Skin moisture and firmness
Give
Hyaluronic acid is found in large quantities in the "dermis," which is located deep within the skin.
There, you'll find collagen, which acts like a pillar supporting the skin's structure, and elastin, which connects the collagen fibers together, with hyaluronic acid filling the gaps between them. By firmly holding onto moisture, it gives the skin hydration and firmness, and also prevents dryness.
The moisture that has been held in,
It brings moisture and firmness to the skin.

Reasons for focusing on hyaluronic acid
Because it's a component that's naturally present in the body.
Suitable for all skin types
Hyaluronic acid is a component naturally present in the human body. Approximately 50% of it is concentrated in skin tissue, making it an essential component for healthy skin.
Furthermore, we believe that an important condition for a skincare ingredient is that it meets the skin's needs—meaning it can be used regardless of age or skin type.
Along with research on the eye,
Hyaluronic acid
Deeply knowledgeable
Hyaluronic acid is found in large quantities in the vitreous humor of the eye, making it an ingredient that we, who have been involved in the research and development of eye drops, consider our area of expertise.
The development of "lactic acid fermented hyaluronic acid*" and formulation technologies that transform a highly viscous state into a lotion-like texture are based on our deep knowledge gained from working with hyaluronic acid.
