Skin That Feels Fortified, Not Stripped

Users say it 'doesn't irritate' like other pore products. It works by replenishing what daily life depletes, so your skin feels resilient, not raw.

Pores That Look Less Noticeable

Reviewers note it 'makes pores look smaller' without harsh scrubbing. The rice ceramides help skin look smoother and more even-toned.

Makeup Applies Without Caking

A common review highlight: 'foundation goes on smoothly.' When your skin's texture is refined, makeup doesn't settle into lines or pores.

Calms Redness from Harsh Routines

If other products left you red, this helps 'calm the skin.' It displaces blame from your skin being 'sensitive' to past routines being too aggressive.

A Simple, No-Fuss Step

Described as 'easy to use' and 'absorbs quickly.' It's a straightforward serum that fits into any routine, morning or night.

Smoother Texture You Can Feel

Users report skin feels 'soft and smooth' within days. It's a tangible result you notice when you touch your face.

Less 'Shiny' Look Throughout the Day

Helps balance skin's natural moisture, so you get less excess oil in the T-zone, leading to a more 'matte finish' as reviewers say.

Confidence in Your Skin's Base

This isn't a cover-up. It's about building a better foundation so you feel good in your own skin, with or without makeup.

Kose Maihada Katsujun was born from a simple Japanese philosophy: your skin's potential is already there, it just needs the right support. In a world of harsh treatments, we saw a need for a gentler, more intelligent approach to pore care. That's why our labs in Japan developed this Pore Solution, focusing on the power of rice-derived ceramides—a natural component your skin already recognizes. Every batch is produced in a GMP-certified facility, adhering to Japan's strict pharmaceutical-grade standards. The formula is backed by over 15 years of dermatological research on barrier repair. It's not just another serum; it's a top-ranked pore refiner in Japan, trusted by users who found typical 'stripping' products made their skin worse. We built this to work with your skin, not against it.

Kose Maihada Katsujun Pore Solution - Rice Power Pore Refining Serum is formulated with a blend of key ingredients designed to refine pores and improve skin texture. The product features rice bran extract, which is rich in antioxidants and vitamins, to brighten the complexion and provide gentle exfoliation by promoting cell turnover. It includes niacinamide (vitamin B3) to regulate sebum production, reduce inflammation, and minimize the appearance of enlarged pores, while also strengthening the skin barrier. Hyaluronic acid is incorporated for its intense hydrating properties, helping to plump the skin and maintain moisture balance without clogging pores. Additionally, the serum contains botanical extracts such as licorice root and green tea, which offer anti-inflammatory and soothing benefits to calm irritation and protect against environmental stressors. These ingredients work synergistically to deliver a smoother, more refined skin surface, reduce pore visibility, and enhance overall skin clarity and hydration, making it suitable for those seeking a targeted pore-care solution.
