Niacinamide Glutathione Serum, 1.69 fl oz (50 ml)

I’ve been using this serum consistently and noticed a visible improvement in my skin tone and texture. It absorbs quickly without feeling sticky, and the scent is very mild. My skin feels smoother and more hydrated, and the brightening effect is gradual but noticeable. The bottle size is generous for the price, and the dropper makes application easy. Overall, it’s a great addition to my skincare routine for an even and healthy glow.

I am currently trying this with the toner from the same brand/product line. I like that it does not leave a sticky finish and seems to sink into my skin well, keeping it moisturized and "spongey," ready for the next step. The scent is not very strong but is slightly herbal, so it may be irritating for some people. It has not caused me to break out or irritated my rosacea cheeks, so I will continue using it and would recommend it for people with sensitive skin. I had some pimples pop up here and there as a result of trying new foundation products recently but they seem to have healed very quickly compared to before, leading me to think it could be thanks to this new product I am trying. I also like the packaging which allows me to control how much product comes out.

This product is very useful and easy to use; it works well and gives good results, but it could be improved slightly in quality.

Thank you very much for this product, it suited me, I like the packaging, comfortable and stylish, I will order more of these products, and recommend them to all my friends and relatives! good!!

The quality of package is very good And the size is ok

A clean, daily step for a clearer-looking, more even vibe. Feels like “I’m being consistent” in skincare form.

I placed my order quickly and efficiently. I’m a loyal customer of this site and I’m now waiting for my package. However, it would be nice if iHerb also offered some product samples.

Started using this product last night in conjunction with the Matrixyl S6 serum, I See Youth eye cream and Eucerin Q10 face cream. My face feels hydrated and although I only really have one tiny micro-wrinkle that apparently only I can see, I woke up feeling like I saw less of it (not sure if that's wishful thinking haha). Excellent packaging and sealed perfectly with the bottle being consistent with product, up until the top. Thick composition and the scent is fine. It has a higher composition than other Niaciminide products which is why I opted for this one. Happy so far.

package: its not glass bottle but a cute square-sized bottle. Scent is okay, no concern. Hope the benefit works – radiant, even tone. Hv yet to use, intent to replace w my Vitamin C. This is the first time buying Niacinamide product - that fits my concern. The benefits I read include reducing the appearance of pores, brightening skin, and minimizing wrinkles. It's a versatile ingredient suitable for all skin types and can be used daily. Some prefer to use it in the morning to protect against environmental damage and others prefer it at night for repairing the skin barrier.

Good smell, easy to use, great quality, size as in picture
