What is Kojic Acid?

Kojic acid can either be a by-product of fermented Sake or Japanese rice wine or a derivative of mushroom. It works by inhibiting the production of melanin, the pigment which gives the skin a brown color.

Thanks to its effectiveness and organic nature, kojic acid has quickly climbed up the popularity ladder and is now a known bleaching agent.

Another reason why people have been drawn to this miracle substance is it’s a gentler alternative to hydroquinone. This is a popular skin lightener that has garnered negative reviews due to its harmful side effects.

Is Kojic Acid Safe to Use?

The compound’s “acid” moniker is enough to give people second thoughts when purchasing products containing kojic acid.

True enough, kojic acid, much like AHAs (Alpha hydroxy acids), has its fair share of side effects too. Anyways, very few skincare products are without a potential side effect.

So, the big question is, “Is kojic acid safe to use”?

Yes, it is. But, users should be guided accordingly when using kojic acid soaps.

Among its side effects include skin irritations (e.g. burning, redness, rashes), increased skin sensitivity, and potential development of allergic contact dermatitis.

Since kojic acid is a peeling agent, new skin becomes exposed to harmful environmental pollutants and UV rays. The exposure increases the skin’s sensitivity which may cause burning sensations.

The skin can become hypersensitive to solar radiations, environmental pollutions and other things. It may begin to develop allergic conditions. These can manifest by burnings, rashes, dryness, itching, and blisters.

Okay, don’t freak out just yet because you can definitely be spared from those scary side effects by doing three things after bathing. You can use this soap to moisturize, apply a generous amount of sunscreen, and grab those umbrellas – as simple as that!

Now that you have an idea of its side effects let’s dig deeper into the wonderful benefits of this miracle acid.

Product Reviews: Our Top 5 Picks for the Best Kojic Acid Soaps



Our Rating

An all-time favorite and a staple of every soap aisle, Kojie San’s Skin Lightening Soap holds the title of the best kojic acid soap. It has an outstanding efficiency and unparalleled popularity in the Asian market.

Initially, the company (BEVI) made and supplied these soaps for dermatologists who prescribe it to patients with skin pigmentation and darkening issues. The kojic acid was reported to have remarkable and fast lightening action.

Realizing its potential, the company launched original kojic acid soaps formulated the traditional Japanese way. They made it even better by adding high-grade virgin coconut oil in the mix to serves as a moisturizer.

We loved that they incorporated tea tree into this wonderful soap’s formulation. Tea tree oil is renowned for its practically endless benefits including clearing acne, relieving psoriasis, and soothing inflammation.

We were so thrilled after trying this beauty bar because we noticed more than just lighten of the skin. It can also diminish dark spots, freckles, stretch marks and even impart anti-aging effects.

Actually, we are already in love with this product because it can fade blemishes, insect bites, and scars in as little as four weeks.

Also, we noticed that it could exfoliate the skin. We tend to shed after the first few washes.

The only issue with we found was this soap is that it tends to be a little drying. So you need to follow it up with a moisturizer after the bath. We didn’t like that it dissolves fast. A bar would probably last less than a week.

What We Like

  • check
    May lighten scars, blemishes, and stretch marks
  • check
    May reduce acne
  • check
    Makes the skin smoother and softer

What We Don't Like

  • May be drying
  • Dissolves quickly

Dermaline’s Kojic Acid Dual Whitening Bleaching Soap seems to be the top contender of Kojie San for the title of the best kojic acid soap because it’s also listed as one of the most efficient whitening soaps to date.

Uniquely, this double-action product combines kojic acid and glutathione for bleaching and whitening purposes.

While kojic acid exfoliates the skin to diminish dark spots and overlying impurities, the gentler glutathione helps in suppressing melanin production to boost kojic acid’s whitening effect.

We loved how this terrific combo can lighten stubborn areas of the skin, especially the underarms and inner thighs, as well as provide deep cleansing to remove embedded dirt and grime.

It also is potent against freckles, acne scars and age spots. Although it may take months of use to get an even skin tone, at least for olive complexions, it still did a good job in brightening our skins.

A surprising thing about this product is its gentle approach in skin lightening, far from the dryness imparted by pure kojic acid bars. Perhaps this soap’s different because it’s combined with glutathione which is way milder than the acid.

However, the soap didn’t last very long because it dissolved faster than regular cleansing soaps.

What We Like

  • check
    May lighten stubborn areas of the skin
  • check
    Provides a deep cleanse

What We Don't Like

  • May not last long

This is a professional-strength soap that differs in its formulation with higher concentrations of kojic acid. It can lead to more significant effects.

Marie France uses a high concentration of kojic acid and papain to help make the skin look even, fairer, smoother and younger with daily use.

The process is gradual and normally takes 8-12 weeks before you see the maximum results – with skin sensitivity playing a major factor.

Papain, an enzyme extracted from papaya, has long been used in skin whitening products. Papain is an all-around compound geared towards skin whitening, exfoliating dead skin, and repairing aging skin.

Furthermore, the enzyme is also a rich source of Vitamins C, A, and E, as well as water and fat which makes it ideal for skin nourishment and as a moisturizer.

True to its claims, this stuff has lightened our dark spots and evened out our skin tones though it took some time to work. After all, everyone’s skin is different.

The best thing about this soap is it will last long, just be sure to keep it away from the areas of your bathroom that the sun can reach.

However, we cannot stress how crucial moisturizing is after bathing with this soap because it can be very drying to the skin.

What We Like

  • check
    May lighten dark spots
  • check
    One bar lasts a long time
  • check
    Exfoliates well

What We Don't Like

  • May be drying
  • Visible effects may take longer

Shouvy’s Kojic Acid and Glutathione Soap offers a potent cocktail of natural ingredients that are everything the skin needs.

We have kojic acid, glutathione, almond oil, coconut oil, grape seed oil, and Vitamin B3.

Kojic acid and glutathione are busy exfoliating and penetrating deep into the skin to remove discolorations and other imperfections.

Meanwhile, the natural oils (almond, coconut, and grape seed) impart antioxidants to neutralize free radicals. They are the culprit behind premature skin aging.

The robust oil trio can leave your skin feeling smooth and soft, thanks to their moisturizing abilities. Almond oil, the most potent of the three, can also remove black and whiteheads and help reduce the visibility of age spots.

The greatest thing about this product is that it may be beneficial for all skin types. We found out that this soap has been wonderful in helping our complexions maintain a lighter skin tone that is about three shades lighter than our original medium brown skin.

However, the soap used to impart a stinging sensation at first but after a few days of acclimatizing our skins, we noticed it faded away.

Similar to other kojic acid bars, the only con of this soap is it runs out quickly. You might consider using a soap dish because it melts fast.

What We Like

  • check
    May even out skin tone
  • check
    Deeply nourishing and moisturizing

What We Don't Like

  • May not be suitable for sensitive skin
  • May cause itchiness



Our Rating

Beyond Perfection’s Triple Whitening Soap is perhaps the strongest whitening soap of them all. This product is packed with the combined lightening effects of kojic acid, placenta, and glutathione.

This triple action soap’s primary goal is to help lighten skin pigmentation, acne scars, age spots, underarms, inner thighs and even private parts through its intense formulation.

By now, you’re probably familiar with what kojic acid and glutathione do. But what about placenta?

Many are grossed out with this ingredient because it is extracted from sheep after birth.

Chinese women who want to have porcelain skins like dolls were the ones who started the placenta trend in skincare.

The placenta is rich in nutrients, minerals, amino acids, and proteins. This nutritional substance can heal the skin by treating acne, rosacea, dull skin and signs of aging.

We’ve only been using this soap for a week, and we loved it. We have combination skin, and this soap was non-irritating at all.

It even helped clear up sunburned spots as well as blemishes and scars. Our skins felt incredibly amazing after every shower, and they look brightened.

Just don’t forget to apply moisturizer and a sunscreen afterward to guard the newly exposed skin from the harmful UV rays.

What We Like

  • check
    May lighten sunburns, scars, and blemishes
  • check
    Suitable for combination and sensitive skins

What We Don't Like

  • May be drying
  • Imparts a stinging sensation

The Bottom line

We were impressed with the skin whitening of Kojie San’s Skin Lightening Soap. This is our top choice for the best kojic acid soap.

Made of pure kojic acid and enriched with herbal oils, it can lighten many problem areas. It may work well on freckles, blemishes, scars and age spots.

Furthermore, it may also reduce acne formation while balancing the moisture content of the skin through the moisturizing abilities of coconut and tea tree oil.

All the products that made it to our list can deliver various benefits. We think they can be of great assistance in case you are able to choose the one that fits you best.
