Nakashima Kaori, the leader of Japan’s whitening movement, has a magnificent and legendary background.Now active on various magazines and TV programs,sheshines with radiance and exceptional charm. But she was once just an ordinary full-time housewife.

However, life is always full of surprises. Just as she was living a peacefuldaily life of mundane routines,the shocking news of her husband’s company on the verge of bankruptcy struck like a bolt from the blue. Faced with such a sudden change, shequickly emerged from despair, threw herself wholeheartedly into the company’s management,traveling from Hokkaido in the north to Okinawa in the south, covering the entire country of Japan, determined to save the company.

Hard work doesnotfailthose who persevere; the company gradually got back ontrack; but nobattered by wind and rain, scorched by the scorching sun, she traveled day and night,the islandKōriHer skin condition gradually worsened,becoming darker and rougher. Faced with her own subpar skin, she gradually realizedthat if her own skin wasn’t in good condition, she would never be able to convince consumers. Therefore, she neededto first create a product that she herself absolutely approved of.And so, she embarked on a long journey researching skincare ingredients and formulations.

Influenced since childhoodby her mother,Nakajima Kōri had always insisted on using the highest quality products, a principle that was fully reflected in her product development process.Willing to invest both money and time, she chose high-quality ingredients and continuously updated her formulas to meet customer needs... Japan has long hadthe saying "White hides seven flaws"(similar to the Chinese saying: "One white covers a hundred uglinesses"), which Nakajima Kōri strongly agrees with. She further proposed that ultimate whitening must be built upon moist and plump bare skin.Her research and development have always adhered to this philosophy.

It was precisely because of her passion for the whitening skincare cause that she was invited to promote her products onJapan’s renowned home shopping channel, SHOP CHANNEL.But surprisingly, in order to demonstrate the real effects of the products, Nakajima Kōri appeared on camera completely makeup-free — something unprecedented in Japanese TV history. With the phrase “I am the proof!” she gained the trust of Japanese consumers and earneda large number of loyal fans,becoming a bona fidetop-selling brand across all of Japan.In just one hour,salesreached1hundreds of millions of yen, earning her the title from Japanese media as the “woman who earns1hundreds of millions per hour,” briefly making her a hot topic.

It was through this opportunity that moreJapanese women came to remember Nakajima Kōri and her cosmetics,and were inspired by her life philosophy: beauty is the power of life — always maintain your most beautiful state and enjoy a confident life. She remains committed to researching and developing high-quality whitening skincare products, hoping that all women can have fair, clear skin and radiate their own unique beauty.

It was her belief that revived a company that was once on the brink of bankruptcy..

It was also her belief that led to the creation of CRYSTAL JEMMY, Japan’s only high-end skincare brand specializing exclusively in professional whitening.

The editor learned thatWhitening Minister Nakajima Kaori, in addition to using her own meticulously developed high-quality whitening skincare products, actually has many little whitening secrets.Among them, the two most crucial points aresun protection at all times and the use ofVCproducts of a certain type.

Nakajima Kaori places special emphasis on sun protection because ultraviolet rays not only darken the skin but can also lead to spots, dullness, wrinkles, sagging skinand other issues.If you want to have fair, radiant skin,sun protection is absolutely the top priority..

The whitening minister’s residencefeatures features such as floor-to-ceiling windowsall made with UV-blocking glass that can block 99.8% of ultraviolet rays, preventing skin tanning and photoaging. Not just the residence—even the car windows are made with the same UV-blocking glass.

Sunscreen is also an essential part of her daily skincare routine. Whether it's sunny or cloudy, summer or winter, Nakajima Kaori always applies sunscreen products. In addition, she also makes sure to use an umbrella when going out to block the damage from UV rays.

Now let’s talk about the whitening minister’s favorite ingredient—the star of the whitening world—0?/span>Vitamin C.In fact,undernormalcircumstances,high-purityVitamin C isveryhighlyVCunstable, easily oxidizing and breaking down, making it unable toStableand easily oxidized and decomposed, making it unable tofor a long timestorage, the effectivenessis also difficult to guarantee.Therefore,the whitening ingredients in her skincare brand CRYSTAL JEMMY are all pharmaceutical-grade whitening components certified by Japan’s Pharmaceutical Affairs Bureau0?/span>—a weakly acidic, stable VC derivative.

Thiswater-soluble VC derivative has a smaller molecular weight, higher penetration, easier absorption, and extremely high stability.

It is one of the most effective whitening and beauty ingredients. 

In 2018, Nakashima Kaori and her brandCRYSTAL JEMMYfurther set the goal of “whitening in a straight line,”fully implementing“whitening”concepts across both skincare and makeup, launching one groundbreaking new-concept product after another.Now, let’s take a look with us at some of the great whitening products that can help you glow from the inside out.

｜Cleanse Thoroughly

To achieve radiant, snow-like skin, cleansing is the first step. Thoroughly removing dirt from the skin’s surface and deep within pores not only improves dullness and enhances skin clarity but also allows subsequent whitening care to work more effectively. When choosing a cleanser, it must be capable of completely eliminating pore impurities while also being gentle enough not to damage the skin barrier or irritate sensitive skin.

｜Essence First Is a Must

Nakajima Kaori’s unique whitening method. Unlike most other essences on the market, she recommends applying your whitening essence immediately after cleansing to take advantage of your skin’s peak absorption time and maximize the brightening effect, restoring your skin to a fair, radiant state.

Immediately after cleansing, it is recommended to apply CRYSTAL JEMMY’s Pharmaceutical Concentrated Whitening & Spot Fading Essence. This allows its effective whitening ingredient, the weakly acidic stabilizedVCinducer, to successfully reach the stratum corneum. It not only effectively suppresses melanin production to prevent spots and freckles, but also fades stubborn acne marks and existing pigmentation, improving rough and dull skin.

This whitening essence also contains three types of ceramides, yeast extract (3),2peptides, collagen, and various other carefully selected moisturizing and reparative ingredients. While whitening, it also infuses the skin with ample hydration, helping sun-exposed skin regain a dewy and fair appearance.

With its light, gel-like texture that is easily absorbed and deeply penetrates, it not only provides sufficient moisture but also leaves the skin surface fresh and non-greasy—definitely a must-have skincare product for summer.

｜Don’t Forget Frequent Hydration

To achieve the healthy, fair skin you dream of, whitening is key—but hydration is the foundation. Especially in summer, with increased UV intensity, your skin often becomes dehydrated even as it gets oily, making summer moisturizing especially important. If you don’t like sticky, rich toners due to the heat,,you can opt for lighter, refreshing toners.

CRYSTAL JEMMY Pharmaceutical Pure Bright Softening Toner not only contains the weakly acidic stabilizedVCinducer—the favorite whitening ingredient of “Whitening Minister” Nakajima Kaori—but also includes dozens of plant-derived natural ingredients. It whitens while soothing and calming sun-exposed skin and replenishing moisture. With its light, watery texture that feels refreshingly non-sticky, it absorbs quickly and deeply hydrates all the way to the base of the skin.
