SEKKISEI Global Brand Muse Number_i (Sho Hirano, Yuta Jinguji, Yuta Kishi) Visit the "Cooling Sekkisei" Experience POP-UP "SEKKISEI COOLING LOUNGE"!

KOSÉ Corporation (Head Office: Chuo-ku, Tokyo, President and Representative Director: Shinji Tanaka) will launch the "Cooling Sekkisei" campaign for its global skincare brand "SEKKISEI." This campaign highlights the refreshing and invigorating sensation experienced when using SEKKISEI products chilled, which is highly popular during the intense summer heat when UV rays accelerate skin damage from dryness.

As part of this campaign, from Wednesday, July 1, 2026, to Monday, August 31, 2026, an experiential pop-up event titled "-Experience 'Cooling Sekkisei' POP-UP- SEKKISEI COOLING LOUNGE" will be held at Maison KOSÉ Ginza. This event offers a new sensation in skincare, "Refreshing Whitening with Cooling Sekkisei," allowing visitors to fully immerse themselves in the experience and combat summer damage.

Prior to the event, the global brand muses for SEKKISEI, the artist group Number_i (Sho Hirano, Yuta Jinguji, Yuta Kishi), experienced special content related to "Cooling Sekkisei" in an icy world that appeared in early summer Ginza.

About "SEKKISEI COOLING LOUNGE"

"SEKKISEI COOLING LOUNGE" is designed with a beautiful ice world as its motif. Upon entering, visitors are enveloped in cool music and the refreshing scent of SEKKISEI, creating a space where they can fully experience the pleasant sensation of "Cooling Sekkisei" touching hot summer skin.

At Maison KOSÉ Ginza, the venue features an "Ice Beauty Bar" on the 2nd floor where visitors can experience "Cooling Sekkisei." Additionally, on the 1st floor, there is a "Freezer Photo Studio" photo spot. The event also includes interactive content such as "My Bottle Atelier," where visitors can design their own lotion bottles, and a rhythm game to learn about the environmental conservation initiative "SAVE the BLUE," offering a multifaceted experience of SEKKISEI.

Number_i Visits the "Cooling Sekkisei" Experiential Pop-Up! Excited by the "Icy World" Appearing in Ginza, Saying "Feeling the Coolness with My Whole Body is a Special Feeling!"

The three artists first visited the "Ice Beauty Bar," where "Cooling Sekkisei" is served like a cocktail. In the space designed to resemble an ice world, Hirano commented, "Feeling the cool sensation all over my body was a special feeling!" The early summer humidity instantly disappeared, and they showed great interest in the ice-decorated tables and photo spots, enjoying the space thoroughly.

They also answered a few summer-themed questions. When asked, "What do you absolutely want to do this summer?" Jinguji immediately replied, "Watermelon splitting!" The other two enthusiastically suggested, "Watermelon is delicious, but we rarely do watermelon splitting! Let's do it in Kishkun's big garden!" To which Kishi quickly pointed out, "I don't have a garden! (laughs)" bringing laughter to the group.

Regarding the question, "Do you like or dislike the summer heat?" Hirano stated, "I tend to dislike it. Japanese summers are quite humid and sticky..." Jinguji added, "I dislike it too. I'm okay with it in L.A. though (laughs). It's dry there." Hirano and Kishi playfully retorted, "That sounds a bit boastful (laughs)." In contrast, Kishi said, "I like summer the best!" He added, "Sleeping with the room super cold is the best, and the food is delicious too," showing his anticipation for summer.

When asked about the "Cooling Sekkisei" pop-up event, Jinguji commented, "It's an 'Ice Beauty Bar' that appeared in the middle of Ginza, making it the perfect place to give your skin a 'cool treat' during the hot summer!" He fully experienced the "Ice Beauty Bar" space while looking around. Kishi delivered a warm message to the visitors, saying, "It feels incredibly good on skin exposed to summer damage and refreshes you instantly, so I really want everyone to try 'Cooling Sekkisei' during this opportunity."

Number_i Challenges Creating a One-of-a-Kind SEKKISEI Lotion Bottle! Jinguji Looks Like a Painter? Each of the Three Shows Their Unique Style!

Next, the three artists took on the challenge of creating their own SEKKISEI lotion bottles at "My Bottle Atelier." They chose illustrations related to the sea and snow, and used eco-friendly paints made from upcycled used cosmetics to color their bottles. Kishi seemed very happy, exclaiming, "It's been a while since I've done something like this! It's nostalgic!"

Jinguji chose a "whale shark" inspired by his nickname "Jin," Hirano chose a "sea turtle," and Kishi chose a "seahorse." They discussed colors and ideas in a friendly atmosphere while designing their bottles. There were moments of intense concentration and consultations as they looked at each other's progress. Hirano struggled a bit, saying, "I might be really bad at coloring!" while Jinguji showed his dedication by holding the drawing up to the light. Kishi remarked, "Are you a painter? (laughs)" Kishi, on the other hand, said, "It's great that we can paint with our own sensibilities, it's fun!" as he carefully applied his unique design, resulting in three original bottles that showcased each of their personalities.

The custom bottles designed by Number_i will be displayed with their handwritten signatures at the "Ice Beauty Bar" on the 2nd floor of Maison KOSÉ Ginza during the pop-up event.

Number_i Gets Excited During a Quiz About SEKKISEI's Environmental Conservation Initiative "SAVE the BLUE"!

Finally, as SEKKISEI's global brand muses, they participated in a quiz related to coral planting activities within the environmental support project "SAVE the BLUE ~Ocean Project~." Jinguji playfully offered Kishi, who answered correctly, "I'll give you a bottle of SEKKISEI as a prize! (laughs)"

Through the quiz, the three artists gained an appreciation for the importance of coral for the earth and marine life.

The visit was filled with smiles throughout.

This Summer: "Refreshing Whitening with Cooling Sekkisei"

What is "Cooling Sekkisei"?

By chilling the lotion, gel, emulsion, or cream from the "Medicated SEKKISEI Brightening Series" in the refrigerator and using it on summer-damaged skin, you can experience a pleasant cooling sensation that tightens the skin, along with deep moisture that penetrates the stratum corneum. For an even cooler sensation, you can freeze the "Medicated SEKKISEI Brightening Multi Gel"!

The refreshing feel of "Cooling Sekkisei" is addictive once you try it, making it an indispensable part of your routine. It's recommended not only for hot summer days when you might feel reluctant to do skincare or for sun-exposed skin, but also after bathing or visiting a sauna.

"Cooling Sekkisei" delivers cool moisture that smoothly absorbs into the skin, filling every corner of the stratum corneum to lead to radiant, dewy skin.

This summer, enjoy SEKKISEI's unique new sensation in summer skincare that will refresh your mind.

*Whitening refers to suppressing melanin production and preventing spots and freckles.

*When using this product, be sure to close the cap tightly and store the container upright in the refrigerator.

*Summer-damaged skin refers to dullness due to dryness, etc.
