    good product but don’t mix w/ vitamin c
    July 19, 2021
    this product is lightweight and not sticky, it brightens the skin but if you mix it w/ vitamin c it may turn your skin to a yellow tone so be aware! by itself w/ Hyaluronic acid moisturizer it works very well
  • Alyona.V
    My new obsession!
    June 15, 2021
    I’m in looooove with this toner! It does everything that it promises! My skin is bright, hydrated and plumped. It is great for layering as well. I will reorder my second bottle, cause this toner will be with me for a long time now.

    Let's start from the packaging: so cool that looks like a design item I'm proud to display (but I don't, since skin care products must be stored far from sun light!). It doesn't have any particular smell. I worried about the texture at first, because I expected it to be more watery and it's quite viscous instead... but it absorbs in quickly with any problem. But the best thing is definitely the result... Guys, I'm SHOCKED!! IT MAKE WONDERS! I'm combining it with mugworth essence, and I can see my skin looks definitely way much better! I can see pimples are going and some small acne marks are fading... I will try to make some pictures to show you long term results.
    IMPORTANT: Since it seems quite a strong product (quite an high percentag of Niacinamide compared to other products, 10%) , I wanna recommend people to TEST IT ON A SMALL AREA before using all over the face. A friend of mine, who has a very delicate dry skin, tried a small amount on her cheek and felt a little burning sensation, which fade away in a few minutes, and told me it felt sticky after the application. It wasn't a bad experience, but it wasn't definitely a product for her. I have oily/ combination skin and I definitely had none of these results. I had a great experience, instead, and I won't stop using it!!

    Love it!

    This works wonders! It really controls the sebum production on my face without leaving it too dry!
  • Leplis
    So far so good
    November 26, 2021
    I have been using it for a week now so i will wait more to see if it has the desired effects

    I've only tried it once so I'm not sure how it works yet. It doesn't have a strong scent and not sticky. I'm liking it so far, no sensitivities or allergic reactions.

    Better Than The Ordinary!
    October 6, 2021
    So much Niacinamide for such a lil price is just amazing!!!
    I have a combination skin+acne and my skin tolerates it without a doupt :)
    I even use it for my nexk & chest...and I can see and feel a great difference already after a few seconds.
    It tickles a lil bit but the result is kind'a combarible to the Niacinamide of Paula's Choice.
    I can recomend it for sure!!!

    PS: It's a plastic bottle and unfortunately not a glas bottle!

    Trying niacinamide for the first time
    October 2, 2021
    Trying niacinamide for the first time in a toner all by itself so far liking One Thing. It is a Korean made product which I enjoy and working it into my morning routine nicely.

    My favorite toner!
    September 28, 2021
    Such a great toner with working percentage of niacinamide!
    You can add it to your products and have a customized skincare!
  • Henriette
    WOW I love this toner!
    September 19, 2021
    I've been using this toner for a few weeks now, and I'm really loving it! As someone who is used to mainly using Niacinamide based products in my serum routine, I have been pleasantly surprised at how well this toner works! It's lightweight but has a bit of viscosity to it. It feels soothing and hydrating, and sinks really well into the skin. My skin feels smoother and looks brighter, and I have a little scar on my forehead that seems to be disappearing a little faster after I started using this. It has also helped reduce the redness in my cheek area. Definitely an amazing toner I would recommend to all skin types! There is also no scent.

    Clean Feeling Toner Serum
    September 16, 2021
    Niacinamide balances sebum (oil) production to help soothe and reduce breakouts, blemishes, prevent dehydration and improve oily skin. The toner soothes and smoothen the skin, and effectively reduces oil and brighten the skin. I applied the toner serum to my face and neck using the One Thing Multi Big Pad. These all-natural cotton pads are soft and absorbent
    making them the perfect vehicle to apply the serum and a great mask for spot treatments. After a few minutes of the Nicinamide application my skin felt smooth and hydrated with no irritation, sticky resuide or harsh fragrance! I recommend for all skin types and sensitive skin too! I will definitely continue to use and recommend user give it a try!
    my favorite new clean beauty toner
    September 3, 2021
    I applied the Niacinamide Toner to my face and neck using the One Thing Multi Big Pad. The all-natural cotton pads are soft and absorbent making them the perfect vehicle to apply the Niacinamide. The toner is lightweight and fragrance free. My skin felt smooth, refreshed, and no sticky feeling. After 10 minutes of the toner application, I followed with the rich, luscious, and fragrance-free One Thing moisturizing Cream. I definitely recommend both products!
