Which brand of kojic acid soap is more effective in skin whitening? There are very few brands out there that really work. Find out which one is the best and learn how to use it by reading this article.

I’ve been using kojic soap for the past twelve years now and I can honestly say that it works. However, in order for it to work, you’ll need to know how to use it, the brand you need to buy and the do’s and don’ts.

What it does and how it works:

  • Kojic acid soap is a very powerful skin lightening soap made from kojic acid, which is also called Sake or Japanese rice wine. Back in the day, Japanese women will slather it on their skin to get a lighter skin tone. It’s a white powdery substance
  • Also known as “kojic” or “papaya kojic,” most people don’t know that the soap works in two steps:
    • Exfoliation – the top layer of the skin is exfoliated to get rid of the dead skin cells on top. This will help kojic acid penetrate the skin deeper. Exfoliation plays a key role in skin lightening because if the skin is not exfoliated regularly, the dead skin cells will start to build up and no matter what skin whitening product you use on your skin will simply not work.
    • Penetration – the main ingredient kojic acid will penetrate the skin to get rid of hyper pigmentation to even skin tone.

What are the benefits of using kojic acid soap?

  • Helps even skin tone – I’m positive on this one. This soap seriously gets rid of uneven skin tone. I tried it on my inner thighs before and bam…dark inner thighs gone.
  • Helps remove acne scars. This is my favorite soap when when it comes to removing acne scars. I used to have moderate adult acne and it really does work A friend of mine who’s black, used to suffer from post inflammatory hyper pigmentation due to acne scars and kojic soap really cleared her face.
  • Helps remove acne/pimples.
  • Helps lightens skin
  • Helps get rid of dark spots on face and body.
  • Gets rid of hyper pigmentation like dark underarms, inner thighs/bikini area, neck, knuckles and knees.
  • Exfoliates and deeply cleanses the skin
  • Helps get rid of blackheads, whiteheads and unclogs pores.
  • Doesn’t make you look like you “bleached” your skin. Kojic acid soap actually gives you that “natural” lighter skin tone and this is one of its advantages. I know a lot of people (especially women) who use skin whitening products and it looks so obvious because they have a “fake white” on.
  • Helps remove sun-related skin problems like sun spots, age spots, brown spots and melasma.
  • Works amazing on medium to dark skin tones.
  • Helps brighten skin.
  • Helps get rid of dark patches and discoloration on both face and body.
  • Results overtime is comparable to getting a regular chemical peel and microdermabrasion combined without the downtime at a fraction of its cost.
  • May help get rid of new stretch marks (reddish in color).
  • May help lessen the appearance of keratosis pilaris and eczema scars.

How to use kojic acid soap for faster results:

Step #1:

  • First, always wet your face with warm (NOT hot) water. It’s always better to use the kojic soap when your pores are open.
  • My top secret: Use a konjac sponge to apply the soap on your face. The sponge will actually buff away dead skin cells (you can also use a facial brush like Mia but I prefer the gentleness of the sponge) and this will help the soap’s active ingredients to penetrate your skin deeper. The result – you’ll see your skin improve a lot faster.
  • Last, wash your face like how you normally would but be aware of the timeframe I listed below.

First Week: If this is your first time using a kojic soap, then you should only use it once a day for no more than 20 seconds. You have to let your skin get used to the kojic acid. Leaving the soap on your skin for more than the time stated above might cause redness and irritation.

Second Week: You can now use it twice a day for no more than 20 seconds each time.

Third Week and so on: It’s now ok to leave it on for 1-2 minutes and use it twice daily.

  • For those who have sensitive/combination type of skin, you may feel some kind of “tingling sensation.” In addition, micro peeling will occur. This is a good sign. Whenever the skin peels, it means that it’s removing the dead skin cells and replacing it with a brand new one so that it’s going to look younger, whiter and smoother.

Step #2:

Wash your face with very cold water for about 2 minutes. Why is this important? Simply because since you opened your pores with warm water, you now have to close it with cold water. I noticed that when I finish washing my face with cold water, my pores are less visible and my skin feels a lot smoother. In addition, there’s less peeling. Maybe it’s just my skin but you should try it to and see what happens.

Step #3:

Dry your face and apply a heavy moisturizer – preferably a heavy skin whitening cream for your face and a whitening lotion for your body. Please note that kojic soap causes skin peeling. Yes, that’s that “dry skin” that you’re seeing. Don’t worry as it’s not really “drying” your skin, it’s actually peeling it to remove the dead skin so that kojic acid can penetrate your skin deeper. It also helps give you that smooth and brighter-looking skin.

Step #4:

Consistently use the soap for about 8 weeks. Note that results will vary depending on skin type. A friend of mine tried the soap before and it only took her about 2 weeks to see results (but she’s not you, so be patient).

Why you should use kojic soap:

  • If you’re like me who have tried so many different products to get rid of skin blemishes like acne scars, dark spots and uneven skin tone, then kojc soap is right for you. This is an amazing and very powerful soap! Not only it evens your skin but it also makes it soft and smooth.
  • It can permanently remove skin blemishes, fade old scars and even out skin tone.
  • This is recommended for those individuals who want to have an even, lighter, brighter and smoother skin every day. If you want to see a huge improvement in your skin and if you want to be confidently flawless from head to toe, then you should start using kojic acid soap today.

Who should NOT use the soap:

  • Pregnant or lactating women – please do not use kojic acid soap if you are pregnant. It’s not safe to use as it will make your skin very sensitive to sunlight. Also, I would not suggest using any kind of skin lightening products while your pregnant. Ask your doctor for further advice on which skincare products to use.
  • Individuals who stay under too much sunlight should not use this soap at all. The reason for this is because this soap contains kojic acid, a very powerful skin whitening agent that can produce adverse effect when used under direct sunlight. Note that if you plan on using any kind of skin whitening product (soaps, creams, toner, etc.) you should not stay under the sun anyway.
  • Impatient individuals – if you’re the kind of person who wants to see results in about 1-4 weeks, then this soap (and any whitening product) is not for you. Why? Because it’s going to take sometime before you see any effects on your skin especially if you’re really dark. However, keep in mind that there are some people who would see results earlier than most of us. Some people I know have seen results after using this type of soap only after a week or two but again, don’t count on it because their skin type is not the same as yours. My recommendation is to use kojic acid soap for about 8 weeks or longer before you give up – even dermatologists would tell you that this is the right amount of time to see if a product would work for you or not.

Is it safe?

I’ve been using this soap for years now and never had any problems, therefore, I would consider the soap to be safe to use.

Pregnant or breastfeeding women:

Do not use the kojic soap as it could make your skin too sensitive to sunlight. Wait until you’ve given birth and stopped breastfeeding before using the kojic soap.

Does it cause cancer?

To date, there are no reports linking kojic acid to cancer.

Acne-prone skin

The soap is safe to use on acne-prone skin but beware that you might experience more breakouts during the first couple of weeks. It should go away on your third week or so (this varies depending on your skin).

Sensitive skin

If you have sensitive skin, I will strongly suggest that you use caution while using this soap. I’m not saying that you can’t use it but you need to use it less often. For example, instead of using it twice a day, using three times a week and see what happens. You have to observe how your skin reacts to it when first using this type of soap.

Is it safe to use everyday?

Yes, if you have normal skin type. Sensitive, dry or combination skin should only use it for about 3 times per week.

Is it safe to use on face and body?


What you should expect:

Side effects:

Please note that all of the side effects listed below will not be experienced by everyone since we all have different skin types. Also, these side effects might last between 1-3 weeks depending on your skin sensitivity.

  • Skin lightening
  • Redness
  • Itchiness (use a heavy cream or lotion to prevent this from happening)
  •  “Tight Feeling”
  • Breakout (happens most of the time if you’re acne-prone)
  • Dry skin (use a heavy lotion or cream)
  •  Peeling
  • Burning/Tingling Sensation
  • Acne-prone: might experience breakouts during the first couple of weeks.
  • Skin irritation – stop using if you experience irritation or decrease usage to once per week until skin gets use to it.

Note: Don’t panic if you experience these side effects because it will eventually go away. It’s temporary.

When you’ll see results:  

  • Results vary depending on your skin type and how fast your skin adapts to the active ingredients. However, it normally takes an average of 4 to 8 weeks before you see results.

Do’s and Don’ts:

  • Do not stay under the sun.
  • Do not rub the skin if it’s itchy (add more moisturizer is the solution to itchy skin).
  • Do not leave on longer than the time frame listed below.
  • Do buy a heavy moisturizer before using the soap.

The kojic acid soap brands that I’ve tried myself:

#1. Marie France Kojic Soap – this is what I’m currently using. So far, it has exceeded my expectation. Like what I said, I’ve tried so many different brands of kojic soap but this brand is the best by far. I’m currently using it on my butt, bikini and underarms area. I also use it on my face maybe 2-3 times a week. I’m acne prone and the acne/pimples I used to have left scars of my face. It removed it and this is just a maintenance soap for me now. This is also a very strong skin lightening soap. The soap box says “maximum strength” and they’re right – it’s maximum strength. One of my co-workers asked me, “why is your face so much whiter that the rest of your body?” That was funny but that’s when I realized that it really works when it comes to skin whitening because when he said that to me, I’ve only been using it for one week!

Ingredients: Vegetable-based glycerine, kojic acid extract, papaya fruit extract, aloe vera, virgin coconut oil, vitamin E, lake yellow 14 (food-grade)

#2. Diana Stalder – I used this soap for maybe six months. This is not just kojic soap but papaya kojic. It did help lighten my skin but I felt that it’s kinda slow so I decided to try a different brand.

Ingredients: Coconut Oil, Water, Sodium Hydroxide, Potassium Lactate, Tetrasodium Etidronate, Fragrance, Propylene Glycol, Papaya fruit extract, Kojic acid, CI 15800

#3. Likas Papaya – I remember using this soap when I was in 6th grade. Back then, I had severe acne and one of my friends who had used this brand told me to try it myself. It worked for her so I wanted to see if it’s going to work for me. Unfortunately, it broke my skin out ever more! I know that my skin type (sensitive) has something to do with it as well. We didn’t have air conditioner when I was growing up so it was hot. I stopped using this soap after a few days.


  • The exact ingredients depend on who made it, however, the main ingredient is kojic acid.
  • Common ingredients: Kojic acid, papain, glycerine, virgin coconut oil, aloe vera, orange scent and color
  • IMPORTANT: Make sure that the ingredients list contains kojic acid and NOT kojic dipalmitate. Dipalmitate is less effective but stable form of kojic acid. It will not garner same effects (just telling you this now so that you’ll not be surprised).

Questions and Answers:

Who can use kojic acid soap?

Anyone can use it, however, people who stay under the sun should refrain from using this soap.

Can I use it on my areolas?

No. I would not suggest to use a kojic soap in this very sensitive area. It’s way too strong.

How long before I see results?

It depends on your skin. Results vary individually, therefore, no one can tell how long before you’ll see its lightening effect. However, this particular soap has to be used every single day (preferably twice a day) to see maximum results.

Can I use kojic soap on my underarms or inner thighs?

Absolutely. However, please be careful when using it in your inner thighs as you do not want the soap so be in your intimate part.

Once I achieve my desired results, can I stop using it?

I wouldn’t suggest to completely stop using it. What I would do is to use it as a maintenance. For example, if you’re using it 2x a day, everyday, then you should just use it 2-3 times a week for maintenance. Remember that this is a topical skin whitening product and the result isn’t permanent.

I recently bought kojic acid from ebay and have been using it for about a week now all over my face and have not seen results yet. Will this soap help with my discoloration from Nair product?
