    5.0 out of 5 stars High strength niacinamide - but also has retinol
    Reviewed in the United States on December 22, 2024
    Verified Purchase
    I ordered this on a Black Friday deal but I hesitated using it as I was a little worried about the strength being 20% -- but I was almost out of my Cosrx 15% niacinamide and wanted to try TirTir's. I have their milk ampoule and vitamin c, which I really love.

    I apply this after cleansing and my vitamin c, or sometimes just the niacinamide alone. I was very happy that this higher strength did not irritate or redden my type 1 rosacea-prone skin.

    Just know that niacinamide serums can be a little sticky or tacky but give it time to absorb. I cleanse, tone, and then wait a little while before applying my vitamin c, then I wait again before I apply niacinamide, then another wait before my serum(s). How long you wait is up to you but I give anywhere from 5 to 15 minutes between these first steps. I think even just a minute or two would be fine - to give the serums time to absorb before applying another one.

    TirTir has some beautiful skincare products and my skin loves the formulas - I also love Beauty of Joseon, Cosrx, and Gangnam Glow.

    Niacinamide in the correct formula and strength, as this one is, gives my face a really nice glow.

    The only thing I wish it didn't have is the retinol - that would have me not reordering this and going for the CosRx instead for my reorder of niacinamide. But if you like blends like this, this is a very nice brand to try.
