Kisocare - Niacinamide Serum 20%

un siero proprio anti vecchiaia! ingredienti potentissimi come nicotinamide che è una specie di vitamina B proprio per le pelli arridi e mature, poi contiene ottimo acido ialuronico e non solo ma zinco ed estratti di radici .. ovviamente io uso solo in inverno e debbo dire che fa il suo lavoro come tutti i prodotti della kiso ! compratelo assolutamente ed abbinatelo con una crema adatta…

Love the texture of this serum - it is a bit thicker than water, very pleasant on the skin! absorbs quickly, does not leave sticky feeling. My skin loves niacinamide and I purchased like 5 bottles from this exact brand.

“I’m very happy with this product! The quality is excellent, it works as expected, and the packaging was very good. Everything arrived safely and on time. I would definitely recommend it and will happily order it again!”

KISOCARE Niacinamide 20% + Zinc Serum (30 ml) is a high-strength Japanese serum designed to improve the appearance of enlarged pores, uneven skin texture, excess oil, and post-acne marks. It combines 20% niacinamide with 4% Zinc PCA for oil control and skin-balancing benefits.
20% Niacinamide helps brighten the complexion, improve uneven skin tone, strengthen the skin barrier, and reduce the appearance of pores.
4% Zinc PCA helps regulate excess sebum and is beneficial for oily and acne-prone skin.
Contains panthenol, four types of hyaluronic acid, Centella asiatica (CICA), green tea, licorice root, and other botanical extracts to hydrate and soothe the skin.

A 20% niacinamide concentration is exceptionally high, so I was initially a bit cautious, but I have experienced absolutely no sensitivity with this KisoCare serum. It is incredibly gentle on the skin while still delivering the potent benefits of such a high-strength active. It has a great, lightweight texture that absorbs quickly and layers beautifully under my heavier moisturizers without any pilling. If you want a highly concentrated niacinamide treatment that won't irritate your skin barrier, this is a fantastic choice

No adverse reactions despite high concentration. Serum has a thick texture hence a small amount can spread easily for the whole face

lo estoy empezando a usar ahora por lo q falta ver resultados, por lo pronto bien, es bastante denso pero igual es de fácil absorción, no tengo textura, mi piel es seca y admite bien el 20% de niacinamida. también soy piel sensible y ni rojeces ni nada, eso sí llevo bastante tiempo usndo niacinamida eso tenerlo en cuenta

Esta marca ha sido un descubrimiento este año 2025. Producto que pruebo, producto que me gusta. Este serum a pesar de tener una concentración alta, no me ha provocado ninguna reacción.

Light texture, can wear under make up. I still not see so much difference but will keep using it.

Me cuesta saber si me ha gustado o no porque necesito más uso y más puestas. La calidad y la talla son tal cual la describen en otros comentarios y la valoración media de otros usuarios

I didn’t try this serum yet but based on all skin care articles it should work well as it has 20% of active ingredient niacinamide.I previously use The Ordinary serum with only 10%. It’s also Japanese product. 30 ml size.

Have just started using this niacinamid and already love it. It doesn't burn or irritate my skin. Takes a lot of time for it to sink in though, but after all my skin feels very smooth and hydrated (yep). Using it every other night and never during days.

"المنتج وصل بسرعة وفي تغليف ممتاز يحميه من أي ضرر. الجودة رائعة تفوق التوقعات، والتصميم أنيق جدًا ومطابق للوصف. تعامل البائع محترم وخدمة ما بعد البيع ممتازة. أنصح بشدة بشراء هذا المنتج لأنه يستحق السعر المدفوع."

un buen producto, rinde bastante y su concentrado es alto. mi piel es sensible y le cae muy bien se nota más brillante y menos apagada.

не оставляет сильной липкости, не раздражает кожу, нет после него высыпаний. Буду заказывать еще
