I’ve been using this since 2020 and I won’t substitute it with anything else! The best for me! I have very sensitive skin that reacts to food, water, body creams, etc. This soap is saving me, and, necessary to say, I don’t need to visit the cosmetology specialist to clean my face since I started using this soap. However, starting from the age of 16 it was a must for me, I had serious issues with skin, even as an adult (I’m 39 now).

HYAKKASO Natural Acne Face Wash Soap

A great product for combination/oily skin, my morning "staple" soap for the last couple of years. It doesn't tighten the skin, leaves it moisturized. It lethers great on its own, but use it with any foaming net - it does wonders.

I am delighted with this series! The soap really works, my rashes in the décolleté area began to disappear, although before, apart from the cream with antibiotics, nothing helped me. I was pleasantly surprised by the effect, although at first I did not believe it. I am satisfied, I advise, it honestly works!

Bought for my teenagers. Sometimes I use it too. The pimples on my face have really been reduced. Easy to use with the mesh. You only need a small amount to produce a lot of foam.

HYAKKASO Natural Face Soap for acne treatment

I received this soap in a small trial version as a gift with the order. At first I was skeptical as I thought that soap would cleanse the face normally and tighten my skin along with a bunch of other negative things, but I decided to try it and I was so surprised! Firstly, the foam. It whips right in the hands into a thick foam without the use of a net! Cleanses sooo well! It also didn't tighten my skin! I usually immediately apply a tonic after washing, but it isn't necessary with this! I like experimenting, but I still apply a tonic. This soap is fantastic! I will order the full version!

HYAKKASO Natural Face Soap for acne treatment

I received a sampler with another order. From the first time using it I fell in love!!! this soap is tenderness itself and it washes away all stickiness and dirt from my skin. Cleanses my pores and tightens them, but only while bathing. Afterwards, my skin does not feel tight but moisturized. All my rashes disappeared. Very economical consumption. Definitely justifies its cost. This soap helped my teenage daughters as well. Compared to Noa Noa gel, this soap wins in all regards!!! The gel did not work nearly as well. The soap crushed it!!!

I received a sample of this soap in the order, I didn’t think that I would use it because I don't have acne, but my skin is dry and I was afraid that it would get worse. I decided to try it to remove the little irritation I have and I fell in love with this soap and eventually ordered more. The soap does not dry or tighten my skin but cleanses perfectly and it helps with irritation.

HYAKKASO Natural Face Soap for acne treatment

I bought this soap because I have blackheads. Firstly, it foams well after using a small amount. In the first week, I didn't notice a difference, but I continued to use it. Then in the 2nd and 3rd week they began to disappear. Now my face has started clearing up and it doesn't dry out my skin either.

HYAKKASO Natural Face Soap for acne treatment

I ordered it for my daughter but I've also started using it. It's very foamy and washes off makeup without causing that tight skin feeling. A little bit goes a long way, so much so that we think it will last for a couple of years.

HYAKKASO Natural Face Soap for acne treatment

I really liked the soap. I suffer from faliculitis in hair growth and acne in the décolleté area. Although this product is unlikely to help cure faliculitis, it definitely helps to fight inflammation and minimize rashes. I like that my skin does not tighten after a shower.

Great soap, gently cleans till my skin is squeaky clean and lathers well. Eliminates all sorts of imperfections. If you use this soap, followed by a peeling then moisturizing mask, rest assured that the glow you get will last for ages.

HYAKKASO Natural Face Soap for acne treatment

Very satisfied with this product. I bought it for my son, who has been suffering from acne for 6 years, nothing helped and we were getting desperate. After the first week of washing with this product, his skin began to clear gradually. Now his face is completely cleared of rashes and the tone has evened out. My son is really happy. I placed a second order not just for preventative measures, but also because it foams very well and gently cleanses his face. It's got a pleasant herbal smell, and is not drying in the least.

HYAKKASO Natural Face Soap for acne treatment

I received this soap as a gift with one of my orders. I tried it and fell in love. A pleasant natural aroma that you feel only when lathering and then it disappears. I have problematic skin and the soap works very effectively. The sample wasn't very big but lasted several months. I used it sparingly. When it was finished, I immediately ordered more and it was much larger than the sample. I'm glad this one will last longer. After using it my skin is soft and there is no feeling of tightness.

HYAKKASO Natural Face Soap for acne treatment

I use soap not regularly, but with some rashes. It pinches my skin a little during washing, dries up inflammation without overdrying my skin and perfectly cleanses! Forms a sufficient amount of gentle foam from a small amount of soap, so this bar will last a very long time.

HYAKKASO Natural Face Soap for acne treatment

Since I began to use, there were no rashes, acne, redness. my skin is smooth and the tone is even. I use it periodically, because my skin is not very problematic. But I think that thanks to the soap, my skin has become almost perfect in terms of the absence of rashes.

HYAKKASO Natural Face Soap for acne treatment

Magic soap! It lathers very well and has a pleasant, not overpowering scent. I like to use mesh to create foam. After washing, does not tighten my skin. Not aggressive in skin care. Inflammatory elements really become significantly less with use, even for several days. The black dots are getting smaller. For a teenager, it's just what you need. The consumption is economical, I think it will definitely be enough for six months.

HYAKKASO Natural Face Soap for acne treatment

I was given a sample of this soap as a gift. my skin is normal, closer to dry. Initially, I did not wash my face every day because I thought I would dry it out. But no, there is no dryness or tightness after washing. Dries inflammation when used with a mesh that forms a large amount of foam. I ordered it for myself and gave it as a gift. Everyone is happy!

HYAKKASO Natural Face Soap for acne treatment

I use this series as an evening care, because the rashes are single. The soap has a specific smell, but I like it because the set is healing. The most delicate soap foam ❤️ The toner came up perfectly, my skin after it is calm and matte. The serum is perfectly absorbed, although in the composition of the oil. The complex gives an excellent result, the redness really goes away! Do not hesitate, try it!!!

HYAKKASO Natural Face Soap for acne treatment

I have a lot of rashes on my face and the soap didn’t help much. The tonic is like water and it refreshes and moisturizes but didn't get rid of the rashes. I liked the serum the most and I feel like its the only thing that worked. Made the rashes lighter. I use it at night.

HYAKKASO Natural Face Soap for acne treatment

I've been using this pack for 3 weeks now. I suffer from periodic closed comedones which grow into active inflammations of various forms. The soap perfectly cleanses and disinfects. The toner leaves no stickiness. The serum hydrates without feeling heavy. My closed comedones become inflamed slightly which leads to quick healing. Everything heals much faster. I'm getting good results using this set so I'll keep using it. Thanks Beauty Ninja!

HYAKKASO Natural Face Soap for acne treatment

32 years old, oily, problematic, reactive skin. I am in love with this set! Reduces rashes and post-acne scars. Moisturizes well. I don’t apply anything after the lotion and serum. I use the serum sparingly, and a small amount goes a long way. Magical products at a reasonable price :) I really hope the prices don't rise. I ordered another one to stock up. I used to use loverite but it didn't work for my skin. These work perfectly for me.

HYAKKASO Natural Face Soap for acne treatment

I have combination skin prone to rashes and dryness. The soap helps fight against rashes, even subcutaneous inflammation turn into less threatening ones and subside quickly. I also liked the serum, it evens out my tone a little. Not a fan of the lotion, perhaps it is better for oily skin.

HYAKKASO Natural Face Soap for acne treatment

I have combination skin and pimples come out with the wrong cosmetics. Tonic and hyakkaso soap work very well, but they dry out my skin, so Ineed to moisturize very well. The serum didn't suit me. I used the serum for 2 weeks with tonic and soap, and I would constantly break out in acne but it was less inflamed than usual. As soon as I removed the serum from the care, my face became clean.
