Star4 qty Great!
fai...@ This serum comes in a 20 ml black glass bottle, the same design of the hyaluronic acid serum. I was a bit scared with this one because contains 15% of niacinamide, this is the highest porcentaje I’ve used but I didn’t experience any irritation or breakouts while using this. This also contains Acetyl Glucosamine that has anti-wrinkles and anti-pigmentation properties and Zinc that helps with the sebum production. The consistency is viscous, absorbs fast and is slightly sticky but after some minutes the sticky feeling disappears, it also gives a beautiful glowy finish. My skin is GLOWING everytime I use this and I honestly love it, overall this is my favorite out of the three.

Star4 qty Minus The Sting
xom...@ It is a great serum don't get me wrong.However, I do believe everyone's skin reacts differently to different skin products. Though I noticed my pores have shrunk and blemishes have decreased when using, I've noticed an unbearable sting when I apply this directly after my toner. I am unsure if it is just the high concentrate or my skin is that sensitive. It is great working over all in light of all of it as my skin is less oily and brighter and it is great to layer and fast absorbing. The best way I've resolved this issue though is to apply the hyaluronic acid serum first prior to the other two serums it alleviates it tremendously.

Star5 qty The Niacinamide 15 Serum – 20ml
kbe...@ Textura ligera y acuosa, rápida absorción, al principio senti un poco de hormigueo pero con el uso se desvaneció la sensación, pero nunca fue irritante, es la primera vez que uso una concentración tan alta de Niacidamida, siempre he usado entre el 3% y 10%. He sufrido de un pequeño brote que me dejo algunas marcas y en la semana que lo utilice pude ver reducción en la producción de sebo y una ligera atenuación de las marcas (que ya se habían atenuado la semana anterior con el sérum COSRX Vitamina C 23%), con el uso de al menos 1 mes se deberán ver mejores resultados en cuanto a manchas y en apariencia de poros. Probado en tipo de piel: Mixta con tendencia a grasa. Recompraría, me gusto bastante, ya quiero ver lo que puede hacer por mis poros con el uso constante.
