Revolutionizing Morning Skincare: The 3-in-1 MiR Cleansing Serum Launches on Rakuten

The New Era of Time-Saving Beauty: Introducing MiR



MiR, a Japanese beauty brand, has launched its innovative 3-in-1 Aqua Cleansing Serum on Rakuten from February 25. This revolutionary product combines cleansing, face washing, and the application of a beauty serum, offering convenience to busy individuals seeking efficient skincare.

Background of MiR: Founded by Mari Kumagai, the company is headquartered in Chuo, Tokyo, and aimed to make skincare more accessible with its unique product offerings. The Aqua Cleansing Serum is designed specifically for modern lifestyles, allowing users to complete their skincare routine in a mere 30 seconds. The idea originated from Kumagai's personal struggle with skin issues and her experience as a beautician in Germany, where she learned about micellar water's gentle but effective cleansing capabilities. The serum contains 94.8% active ingredients to cleanse while retaining moisture, making it suitable not just for evening cleansing but also for quick morning routines.

Since its launch on Amazon last September, this serum quickly gained popularity for its ability to fit seamlessly into a morning routine. Customers began to share their experiences, praising the product for:
  • - Reducing preparation time
  • - Being gentle on sensitive skin
  • - Smoothing out areas around the pores
  • - Providing a hydrating feel despite being a wipe-off product
  • - Allowing for immediate makeup application afterward

These factors led to increased demand for the serum as a quick morning skincare solution, prompting the decision to launch on Rakuten to reach a wider audience. To celebrate this launch, MiR is offering a 10% discount until March 14 and includes a free pump (normally priced at 398 yen) with every purchase.

Unique Features That Set MiR Apart



One standout characteristic of the MiR cleansing serum is its gel-like, thick texture. This formulation minimizes friction by creating a cushion between the cotton pad and the skin, allowing dirt to be lifted away gently without harsh scrubbing. Users have reported:
  • - Smooth skin after use
  • - Persistent hydration without stickiness
  • - A transformative experience that changes how they view wipe-off cleansers

The multifunctional design not only addresses the needs of natural makeup removal but also eliminates the need for a double cleanse. It is even suitable for those with eyelash extensions. Furthermore, it can be utilized in various situations, such as:
  • - When water isn't available
  • - While traveling or commuting
  • - During emergency situations
This versatility enhances the product's appeal for users both at home and on the go, ensuring consistent satisfaction regardless of location or circumstance.

Special Limited Edition Launch on Rakuten



In conjunction with the launch on Rakuten, MiR is providing a limited edition pump set. This decision stemmed from a customer survey where around 80% indicated that a pump would be convenient. The pump set also comes with a 10% discount until March 14. Once the limited offer ends, the pump will be offered as a standalone product. This thoughtful addition has brought an extra layer of convenience to the daily wiping routine.

Behind the Development



Mari Kumagai's personal experiences navigating skin challenges led her to focus on 'gentle cleansing.' Her time in Germany, where micellar water is widely used, influenced her approach to creating a product that preserves natural moisture while effectively cleansing. The development involved rigorous formulation testing over a span of two and a half years, refining the product to cater to the unique skin types and needs of Japanese consumers, ultimately leading to the birth of this essential product that combines cleansing, face wash, and a beauty serum.

Message from the Founder



Kumagai states, “I developed MiR with the aim of offering easy yet effective skincare that can be seamlessly integrated into busy lives. We will continue to create products that support not just healthy skin, but also a healthy mindset.”
