Didn’t burn me!
UPDATE: I have been using this soap for a few months now. Usually every other day, as that's when I shower. My melisma is still in full swing. Meaning it hasn't help fade it at all. HOWEVER, I haven't had any cystic acne since using it! For that alone, I will keep using it! My skin feels extra clean using it. Also, I tried it on my privates - since that seems to be all the rage lately. I was very dry and scratchy "down there" afterwards. To the point I needed to apply some lotion or something. (I ended up using some Medela nipple lanolin - figuring that was safe for nips and babies to eat.) If you are going to try to lighten your privates, just know you might feel scratchy, too. Original review: Okay, I have only used this once, but I was terrified to use it after seeing other’s reactions. I did a patch test on my inner elbow, let it sit for a few minutes, washed it off and waited 24 hrs before actually using it in my face. So far, I lathered it up and washed my face. I let it sit for about 2 mins, then washed it off. My face didn’t feel clean, so I followed up with my regular cleanser. Tomorrow, I will use my regular cleanser 1st, then use this soap. I can’t tell if it is helping with my melisma yet, but I just wanted to say that I didn’t have my adverse reactions to it. I will update after using it more. The soap smells good & lathers well. Don’t know about the lightening or brightening effect yet.

Effective and Gentle – Koji White Pure Kojic Acid Soap Delivers Visible Skin Brightening Results!
I’ve been using Koji White Pure Kojic Acid Skin Brightening Soap for a few weeks now, and I’m seriously impressed with the results! If you're looking for a gentle yet effective way to exfoliate, brighten, and improve the appearance of your skin, this soap is definitely worth trying. First of all, the soap is formulated with kojic acid, a powerful ingredient known for its ability to brighten skin and reduce dark spots, hyperpigmentation, and uneven skin tone. I’ve struggled with some dark spots and blemishes on my face, and after using this soap consistently, I’ve already noticed a noticeable difference. My skin looks brighter, more even-toned, and feels much smoother. The soap itself has a glycerin base, which makes it incredibly gentle on the skin. Despite its exfoliating properties, it doesn’t feel harsh or drying like some other exfoliating soaps I’ve tried. In fact, it leaves my skin feeling moisturized and soft, not tight or stripped. I appreciate that it doesn't have any harsh chemicals, making it suitable for both face and body. The lather is rich and creamy, and a little goes a long way, which makes the bar last for a decent amount of time. I use it in the shower and also apply it to my face as part of my evening skincare routine. It rinses off easily without leaving any residue behind. I also love that this soap is non-irritating, even on my sensitive skin. It doesn’t cause redness, breakouts, or any dryness, which can sometimes happen with other brightening or exfoliating products. It’s perfect for daily use, and I've felt comfortable using it both in the morning and evening. If you're looking for a natural and affordable way to brighten your skin and fade dark spots, I highly recommend Koji White Pure Kojic Acid Skin Brightening Soap. It’s effective, gentle, and delivers visible results without being harsh on your skin. After a few weeks of use, my skin feels healthier, brighter, and more radiant. Definitely a staple in my skincare routine now!

Breaks your skin out!!! Made in THAILAND not Japan
I waited a while to write a review of this Kojic Acid soap because I wanted to give it time to...work. I ordered the soap on TWO separate occasions within a span of six months. There are two bars in the box and both times I ordered, it was delivered on time, and well packaged. Why did I order this soap? I have Keratosis Pilaris and was hoping to find a soap that could help with exfoliation, as well as helping lighten hyperpigmented areas like between my thighs,and other scars or marks left behind from skin breakouts. Usually,I use glycolic peels and lactic acid to help with hyperpigmentation since I have more of a chocolate complexion. So I thought I would give this soap a try. I will begin with the positives. First,this soap is nicely packaged and smells like...ORANGES! The first month,I used the soap... not everyday but a few times a week. I LOVED IT! Between my thighs is lighter now and my skin would feel exfoliated after leaving it on for about five minutes,and then rinsing it off. THEN..... After a few months of using it, MY SKIN STARTED TO BREAK OUT. I'm talking about first,my skin would become EXTREMELY ITCHY. Then little bumps would pop up all over my body. I never had blemishes on my chest area. NOW I DO. I wanted this soap to help me get rid of blemishes! Not to cause them. Even as I type out this review,my skin is itching terribly! I used the soap this morning. My skin is always a bit dry afterwards,but then I use lotion or oil to moisturize. At this point,I am SURE it is this soap that is causing grief. Since I am dark skinned,I now have to repair the damage done from this soap. It's upsetting honestly. I know some people will STILL purchase this soap even though there are numerous reviews of it breaking peoples skin out.But just know,you've been warned about the adverse affects. I'm going to go back to using glycolic acid and lactic acid to help fade blemishes and exfoliate. I will never purchase this soap again.
