A medicated serum focused on dual whitening※2 and wrinkle improvement: "JC MEDIBEAUTYS Whitening Emulsion Serum"
JC MEDIBEAUTYS Whitening Emulsion Serum is a medicated serum launched by Jiyugaoka Clinic Doctors Cosmetics Co., Ltd. on July 1, 2026.
In addition to whitening※2 care with two active ingredients, it contains seven moisturizing ingredients. With these, the serum approaches a lack of firmness※3 and dullness※3, aiming for "even-toned beauty."

It is designed to combine a fresh feel that blends into the stratum corneum with a plump, supple finish. The company aimed for the comfort of being wrapped in a veil of moisture.
It also addresses the worry about moisturizing power that often comes with whitening※2 serums. The company explains that it keeps skin moisturized while also approaching skin that tends to be dry.
This serum aims for a bright, even-looking※4 skin impression, translucence※1 from moisture, and smooth skin.
Addressing the new challenges demanded of whitening※2 serums
According to Jiyugaoka Clinic Doctors Cosmetics, awareness of UV protection has been growing in recent years, while new concerns such as "dryness," "rough skin" and "lack of moisture" have emerged in the whitening※2 care market.
To respond to these concerns, JC MEDIBEAUTYS developed a serum that goes beyond simple whitening※2 care.
This product brings whitening※2, wrinkle improvement, prevention of rough skin and moisturizing together in a single bottle.

A multi-faceted approach with key ingredients and technology
Whitening※2 and wrinkle improvement with two active ingredients
This product contains tranexamic acid and niacinamide as dual whitening※2 active ingredients. These two ingredients aim to suppress the production of melanin and prevent spots and freckles.
Niacinamide in particular is an active ingredient recognized for wrinkle-improving effects as well as whitening※2 effects. By guiding skin toward a plump, smooth, even surface, it supports a glowing skin impression.
Preventing rough skin and keeping skin healthy
The serum contains dipotassium glycyrrhizate as an active ingredient for preventing rough skin. This helps prevent rough skin and maintain healthy skin condition.
Liquid crystal emulsification technology that combines freshness and moisture
The formula uses liquid crystal emulsification technology that forms a lamellar structure similar to the intercellular lipids of the skin. This is achieved with lecithin※5, a type of phospholipid.
This technology is described as combining a fresh feel, smooth absorption into the skin and a plump touch after use.
By using lecithin※5 as an emulsifier, water and oil are stably emulsified, and various beauty benefits are expected, such as good absorption into the skin and prevention of moisture evaporation.
Seven moisturizing ingredients that reach the stratum corneum
Seven moisturizing ingredients are included to moisturize※6 the skin and keep it healthy. They are ascorbic acid 2-glucoside, glutathione, melissa extract, polymethacryloyloxyethyl phosphorylcholine solution, Codonopsis pilosula extract hydrolysate, ectoin and seaweed extract-1.
These moisturizing ingredients reach the stratum corneum, and with morning and evening use they keep moisture in for a long time. By moisturizing, the serum aims to give skin concerned about dullness※3 caused by dryness a brighter look.
