Introducing Innovative Beauty Products: EYEZ and SAICHA Launch at Isetan Shinjuku

New Arrivals at Isetan Shinjuku

The prestigious Isetan Shinjuku's Beauty Apothecary has recently welcomed two remarkable beauty products that promise to revolutionize skincare: EYEZ's "Proud Eyes" eyelash serum, and the rare beauty oil from tea seeds, "SAICHA." Developed by PS International Co., Ltd., these products highlight a commitment to innovative beauty solutions.

EYEZ's "Proud Eyes" Eyelash Serum

Launching on December 24, 2025, the "Proud Eyes" eyelash serum is a groundbreaking product designed for eyelash care. EYEZ, a brand known for its expertise in eyelash and eye area care, incorporates live collagen in its formulas. This unique ingredient, which focuses on delivering fresh collagen to enhance eyelash strength, is unprecedented in the eyelash serum industry. The product features a two-part formula that activates collagen immediately before application, ensuring maximum effectiveness and freshness.

For those concerned about the delicate state of their eyelashes due to aging and everyday wear and tear, the serum combines three potent ingredients: Pyridoxine, Capixyl, and WideLash. These components are meticulously balanced to provide comprehensive care for your eyelashes, offering benefits such as increased strength, moisture, and overall health for the lashes.

The serum is available in limited-edition packaging adorned with pearl stones, making it a perfect self-reward gift. Each set includes 3ml of the eyelash serum and one L Cube, priced at ¥13,200 (tax included).

SAICHA: Pure Beauty from Tea Seeds

In addition to eye care, PS International introduces a unique skincare line featuring tea seed oil under the brand "SAICHA." Sourced from the scenic abandoned farmlands of Shizuoka, Japan, this oil is a precious find, extracting only a drop from two tea seeds. It is formulated to provide remarkable anti-aging benefits, enhancing skin hydration, glow, and elasticity. The oil is not only effective against fine lines but also suitable for sensitive skin, following rigorous patch testing.

The first product in the SAICHA range is the "CH Facial Oil," known for capturing the essence of the freshly squeezed tea seed oil, bringing the nature of the farming landscape to your skincare routine. Available in a standard size of 20ml and a travel-friendly 5ml variant, the product is priced at ¥4,950 and ¥1,980, respectively.
