  • Coni nuñez
    niacinamida
    November 30, 2025
    me encanta este serum, es segunda vez que lo compro, me quita mucho la textura de la piel y me la deja lisa, me gusta mucho
  • lalalaconi
    Un serum potente
    November 26, 2025
    Este Hyper Niacinamide 20 Serum de Isntree me sorprendió muchísimo. A pesar de la concentración alta (20%), no me irritó la piel y se absorbe súper rápido.
    Lo empecé a usar para manchas, rojeces y textura irregular, y en pocas semanas noté la piel más pareja y luminosa.

    También ayuda a controlar el sebo sin resecar, y se siente muy ligero, ideal para usarlo tanto de día como de noche.

    Me encanta que incluya:
    • Ácido hialurónico → mantiene la piel hidratada.
    • Zinc PCA → baja inflamación y controla brillo.
    • Arbutina → potencia el efecto antimanchas.

    Si buscas algo fuerte pero efectivo para mejorar tono y manchas, este serum vale totalmente la pena. El bundle de dos unidades sale muy conveniente.

    100% recomendado.
  • Katia

    Wonderful niacinamid
    November 9, 2025
    This is my first experience with so much high percentage of niacinamid. I was a little scared to start, but everything went smooth. Still need some time to see real changes in my skin.
  • Sara Amer
    I have used it before and I will buy it again
    October 26, 2025
    It's good, good. I think it's the best niacinamide serum I've ever tried. This is my opinion and the opinion of everyone I've had use it.

    Top, super Wirksamkeit
    October 16, 2025
    Ein wirklich gutes Produkt zu dessen Wirkung ich aktuell aufgrund kurzer Anwendung noch wenig sagen kann; jedoch sehr gute Verträglichkeit und Anwendung!

    The product is still under testing, but for now, it seems pleasant, and its suitability may vary depending on skin type and personal preference.
  • Werenfried
    gentle but effective
    October 6, 2025
    this serum works so well on my oily skin. its only 20ml but you only need 3 drops for whole face

    Perfection
    September 28, 2025
    Been on the hunt for a strong Niacinamide serum, I was using the cosrx one but it's in very heavy glass packaging. This one is small, lightweight, perfect for travels and is stronger. Don't sleep on this!
  • Vardaan
    Good
    September 25, 2025
    I just started ysing this one. i have used a different niacinamide product regularly before. but this one feels stronger so i am starting slow. (couple days a week) working good for now.
  • amandaputrivanderveen...
    Works so good
    September 16, 2025
    Started using this to help with pores and uneven skin tone. It’s lightweight, sinks in fast, and doesn’t feel sticky at all. After a few weeks my skin looks brighter and smoother, and my pores look a bit smaller.

    Comigo não foi imediato, mas com o passar do tempo e das aplicações começamos a ver os resultados, e um acabamento suave e luminoso. Recomendo.
