What the gurus are saying

This niacinamide serum impresses for doing double duty: it hydrates while keeping oiliness in check, a balance that matters for people managing both concerns at once. The 10% niacinamide pairs with arbutin to tackle dark spots and uneven skin tone, making it a solid pick if discoloration is something you're working on. A couple of gurus have weighed in so far, both giving it warm marks, but there isn't a large body of takes just yet.

"This gives us a beautiful primer and a niacinamide serum, which I do not have on my list, but it is nice to have."

"This niacinamide from TIAM is so good. It is lightweight, it is everything that we ask for in K Beauty. It is hydrating but it still helps to mitigate oil control. It's got not only vitamin B3 which is our niacinamide at 10 percent but it's also got arbutin and it's so wonderful if you are someone that deals with discoloration in the skin and dark spots. [...] This is going to be your friend."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Niacinamide

Niacinamide has evidence behind it for redness, uneven tone and supporting the skin barrier, and it is usually well tolerated even by skin that reacts to most things.

Humectants and emollients

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.
