Born from the desire to "cherish hands" during the COVID-19 pandemic. New concept hand cream "Shinkoro Cream" focusing on HSP (Heat Shock Protein) launched.

Smartphones, doorknobs, money... Hands, which touch various things every day, are exposed to external stimuli without us realizing it. Repeated hand washing and disinfection to keep them clean can lead to skin problems such as "dryness," "roughness," and "chapping."

"Shinkoro Cream," developed by Strepair, solves these problems with two ingredients.

The first is benzalkonium chloride, which keeps hands clean while protecting them from dryness.

This ingredient, often used in medicated hand creams, protects the skin on your hands from daily contact.

The other is Artemia extract, which activates the function of HSP*1, a beauty protein naturally present in the human body.

Artemia are zooplankton that survive in harsh environments such as extremely high-salinity salt lakes.

The energy components contained in Artemia extract help HSP in the skin support the synthesis of proteins related to skin elasticity, such as collagen.

"Shinkoro Cream" also contains abundant natural ingredients*2 such as shea butter, rosehip oil, and jojoba seed oil, which smooth and moisturize hands concerned about chapped skin, cracks, and dryness.

Its smooth texture and lack of scent allow you to use your hands immediately after application,

without interfering with work or housework. Hand care, which you're concerned about but always put off.

Making Shinkoro Cream a habit cultivates beautiful hands that won't be defeated by busy days.

*1 HSP is a protein that repairs damage to the skin and body caused by UV rays and stress, protecting us and keeping us healthy. The reason a wilted lettuce becomes crisp when placed in hot water is the action of HSP within the lettuce. Because it has the property of becoming active when warmed, it is called "Heat Shock" protein.

*2 Rosemary leaf extract, chamomile flower extract, lavender flower extract, cornflower extract, linden flower extract, Roman chamomile flower extract, St. John's wort flower/leaf/stem extract, calendula flower extract, beeswax, Noto deep sea water.

Message from Mika Sagami, Representative Director

"Hands touch so many things, they get dirtier than you think." I was raised being told this from a young age, and came to believe that hands are an important part that can sometimes carry invisible things.

That's why keeping hands clean is so important. However, on the other hand, there's the reality that being too conscious of hand washing and cleanliness leads to concerns about dryness and chapped hands.

"The stronger the protection, the greater the burden on the hands."

During the COVID-19 pandemic, when hand washing became essential, I felt this particularly strongly, and began developing this product.

To be able to use them comfortably, multiple times a day, while keeping hands clean.

To be smooth and not interfere with work or housework, yet still provide moisture. We repeated numerous prototypes to achieve this balance.

Furthermore, cosmetics have rules regarding the expressions that can be conveyed due to legal restrictions. We are still experimenting with how to deliver the message we truly want to convey to everyone, accurately and without misunderstanding.

Even so, the desire to deliver a product that can support the feeling of wanting to "protect loved ones" and "protect oneself" has not changed since the initial development.

I would be happy if "Shinkoro Cream" could gently protect everyone's hands and be a product that can be used comfortably in busy daily lives.
