I saw a difference with even one use.
I've struggled with dark marks from skin issues since childhood, and this soap made a noticeable difference in evening out my skin tone. It doesn't feel stripping like other brightening soaps I've tried, and my skin actually feels more hydrated after use. The lather isn't particularly luxurious, but that never mattered much to me. It's a plain white bar nothing special to look at but it smells nice. Would recommend for anyone dealing with hyperpigmentation or uneven tone.

Not worth it
Didn’t see any changes on my skin, so much money for 2 tiny bars of soap not worth it

This soap is great
After first use of the soap, my skin felt like it had truly been clean, and not dried out as I had expected. I plan on using it, only once a week however, I found twice in a week to be too much for my white skin, not for the effects of evening my skin tone, but over use of the product can ruin the great effects it has on the skin. Yes, this works for white folks, it gives you younger looking, healthier looking skin, body and face, which I noticed first use. Everything in moderation, we can all learn a lesson from Goldilocks, as it can be applied to pretty much everything.

Did not see any changes, fine as a regular soap I suppose
I have some age / sun spots and was really hoping that this would lighten them at least a little as
they are very noticeable. My skin is very fair / light and I’ve used two full bars (very small) every day for a few months now and have not noticed a single bit of improvement. (Yes, I wear sunscreen every day and have a dermatologist that recommended other products but not this one). The soap itself smells fine, but has not improved my skins color. I would say this is not effective and would not recommend this.

Hydrating lotion
I’m not sure about the skin care properties of this lotion. I haven’t used it long enough or consistently enough to state that it helped with my hyper pigmentation. However, I can’t say that it absorbs really well. It feels comfortable on the skin. And it is super hydrating. I’m considering purchasing it.
