Love this serum, forever repurchase. It's extra light so you can layered it under anything. It has really even out my skin tone. 

This is so lovely to use and doesn’t cause any breakouts. Usually my skin can be quite sensitive to niacinamide but this is quite gentle yet very effective in brightening up the complexion 

Watery , you don’t feel it in the skin . My favourite niacinamide even if it costs the double from other brands 

watery texture that absorbs in seconds, great for layering really helps to even skin tone, and also a great antioxidant  has the best texture of all niacin amide serums out there

This is my favorite niacinamide serum. I actually prefer the water like texture and I use it right after my toner before moving on to the next step. It dries quickly and can be used with other serums without having to worry about thickness. Niacinamide has many benefits and this serum has done so much for my texture and pores. It also helps with old acne scars.

It is a good product, but there are better niacinamides. Just to pricey for me.

I have been repurchasing for years! It has a very light texture which makes it perfect for layering (I use it as the first step), sinks in immediately  it's antioxidant, evens skin stone, helps to reduce the appearance of pores. love it!

It's a lightweight serum, I do find it difficult to spread so I mix it with a hydrating serum.  On most days my face is less oily at the end of the day but on others I feel like it doesn't work at all, I wonder if a higher strength would be better for me.

Best Niacinamide serum, not irritating at all even though the percentage is higher than the regular ones

It’s pricey and i didn’t see impression in first use, but day by day it’ll make a difference for my acnes. After first bottle i bought 20% nia serum from Paula’s Choice and it’s omggggg. Huge fan of niaciamide!!
