Review: Kojie San Kojic Acid Soap vs Diana Stalder Papaya Kojic Acid Soap

Hi Taylor,

I’m trying to find out which one is better: Kojie San or Diana Stalder Papaya Kojic Soap. Have you tried both? Do you have any input?

Hi Shaikh,

I’ve actually tried both before and to make my review crystal clear, I created a comparison chart below. Honestly, both are effective but it really depends on what you’re looking for. I like a soap that’s exfoliates my dad skin cells. This actually helps with the whitening process. Remember that exfoliation is a must if you want to lighten your skin.

Can I use kojic soap to lighten dark underarms or dark private parts such as v’s and butts? How well will it work? And for how many days? Thanks!! ^_^

Yes, you can use the soap to lighten the underarms, butt cheeks but not the vaginal area. That’t way too sensitive and you should avoid using the soap on the that part.


Can we use this soap 4-5 times a week?

Yes, you can but don’t forget to wear a heavy moisturizer.

Hi I order the Kojic acid soap just for dark spots my legs because I have really dark spots ,I’m from the Caribbean it’s always sunny so that makes my skin worst . I wanna clean it up and even my skin tone. I was wondering if u know if I can use the soap on dark spots only or all my legs and if I stop using it will it continue to lighten my skin or no?

Yes, you can use the soap on your dark spots but you have to continue using it everyday to avoid the dark skin from coming back. In addition, you have to stay away from the sun.

Hello. If I use Kojic soap, when will I see the result? And After I use Kojic soa, what brand of body lotion can I use? Can I use, victoria secret body lotion, or Niveo body lotion, or Skin white body Lotion?


I can’t give you an exact answer to this question because I am not aware of your skin type. Everyone’s skin is different. However, the average time frame is 6-8 weeks of continuous use. You can use any lotion but I would suggest trying a skin whitening lotion or cream to see better/faster results.

Question from Amna:

What’s your question?: is kojie san soap better at lightening skin or is diana stalder soap better at whitening i dont wnna waste my money plz give me honest opinion! ty

Answer: I prefer Diana Stalder better due to its exfoliation effect.
