Kojic Acid Soap – 6 Tips to Get Results in 7 Days


Kojic acid soap is a skin whitening product with its main ingredient being kojic acid.

Kojic acid is an organic compound coming from Japan, derived from fungi-like mushrooms, used in the Japanese sake, the Japanese rice wine.

If you are reading this maybe you have already heard about the benefits of Kojic acid for whitening the skin and healing this spot.

In this article I would like to share some advice about the use of Kojic acid soap, so you can take the healthiest choices when it comes to your skin whitening routine.

How does Kojic Acid Soap work?

It exfoliates your skin by removing its outermost layer – the dead skin cells, the excessive oil and dirt. In this way, new, fresh and clean skin is revealed and we are feeling more beautiful and charming.

It is also responsible for reducing the production of melanin deep within our skin layers. Therefore, it stops the development of pigments which darken the skin.

Being a natural product, the kojic acid soap provides a healthier alternative to the chemical skin whiteners.

What are the benefits of using Kojic Acid Soap

Although kojic acid soap is known mostly for its skin whitening functions, there are additional benefits of its regular usage which can make your skin smoother and more glowing.

      • Kojic acid soap is a fighter against melasma, hyperpigmentation and dark spots.
      • Dirt, blackheads and whiteheads cause our skin to look dull and dark. Through exfoliation, the kojic acid soap removes these skin enemies.
      • Sick of acne? The good news about Kojic soap is that it is dermatologist-recommended for fighting off bacteria-caused acne and blemishes. Because of its high glycerine content, pimples, acne breakouts and blemishes are easily removed.
    • Fights freckles topically by reducing the melanin.

6 tips for a better use of Kojic soap for getting faster results

There are some tips for a better use of Kojic soap for getting faster results.

    • The kojic acid soap provides best results if in its ingredients there is papaya. The papaya extract combined with kojic acid works very effectively for whitening and healing the skin.
    • Use exfoliating gloves or sponge to help remove dead skin and reveal your new flawless skin faster.
    • ​Take care of your skin exposure habits. Try to spend less time under the sun so that you can avoid re-darkening.
    • If you have a sensitive skin - build up the time span for the soap on your face to 2-3 minutes.
    • If your skin is normal - the soap can stay on for up to 5 minutes.

    Why use Kojic Acid Soap?

    Lighter and softer skin with no spots are something everyone wants. Nowadays we are much more aware of our health than we have ever been before, thus, we are always searching for the most natural , least-harming and yet effective beauty treatments .

    After you have had enough of skin problems, dark spots, uneven skin tone and of trying many different procedures and products, you just need something that will work and will not damage your skin. 

    Being a natural and dermatologically-approved product, kojic acid soap is a good choice that will whiten your skin tone in the long term. It also keeps your pores bacteria-free. You don't have to worry about allergies when using it - it is certified hypoallergenic promising no dermatitis and rashes.

    When you should not use it?

    As any effective product, Kojic acid soap should be used with caution. Because kojic acid reduces the production of melanin, your new, fresh skin will be much more sensitive to the sun. This means that if you know you are going to be exposed to direct sun light often your skin will get sun-burn very quickly.

    If you are expecting very fast results than kojic acid soap is not the best choice. The process of action is slow and gradual, providing long-term lasting whiteness.

    Side effects you should not panic about

    Kojic acid soap is a potent product that really works. Food, cosmetic products, medicine - we respond to almost everything differently.

    As any cosmetic treatment that is efficient, there are some potential side effects of its usage:

      • You might experience dryness of the skin. What can help you in this case is to use good amounts of moisturiser.
      • Sensitiveness. After the exfoliation, your new skin will be more sensitive to many factors as sun exposure, pollution and other skin products.

      • Itchiness.

      • Skin Irritation. This side effect can occur mostly if your skin is very sensitive. The kojic acid in the soap is not enough to cause irritation on not too sensitive skin.

    Please note that you don't have to experience all of the given examples of side effects.

    Depending on your skin type you might see some of them or not experience any.

    All of the given side effects are just a temporary phase and you shouldn't worry if they appear.

    ​How long it takes before the results are visible

    Dermatologist and skin care companies recommend using the kojic acid soap for at least 8 weeks. If you have the patience you can increase this period to 16 weeks to see the ideal results. 

    Still as any cosmetic product, the time it takes can differ personally depending on your skin type. Some customers report a change after just one week of applying the soap.

    Other conditions, like the health of the skin, also can determine the result of the kojic acid soap usage. It will perform best on a healthy skin.

    The general rule would be - the longer you use the soap the lighter your skin will become.
