Kukui Lash Eyelash Serum will be available at @cosme TOKYO from Wednesday, April 29 to Tuesday, May 26, 2026.

This product began online sales in August 2025, but with the desire to provide more customers with the opportunity to experience the product firsthand, it will now be sold for a limited time at @cosme TOKYO.

Kukui Lash Eyelash Serum is an eyelash serum that provides all-around care from the roots to the tips of the eyelashes, resulting in firm, resilient, and lustrous eyelashes that make an impression even without makeup.

In recent years, natural eyelash makeup with length and volume has become a trend, and eyelash care has garnered attention. While there is a demand for high care effects, concerns about eye area troubles such as redness, itching, and pigmentation are also seen. In response, we focused on "Kukui Nut Oil*1," a naturally derived ingredient traditionally used for hair care in Southeast Asian regions, including Indonesia.

It took seven years from the discovery of Kukui Nut Oil*1 to product commercialization. By applying advanced*2 hair technology, we propose an eyelash serum that moisturizes eyelashes and delicate eye areas, and conditions eyelashes from their foundation*3.
