10% Niacinamide Serum

A week into once-daily use, this user has had no issues with The INKEY List Niacinamide.

“I only got it a week or so ago so I’ve been using it just once a day to make sure I can tolerate it; and so far no issues.”

After two years of religious use of The INKEY List Niacinamide, this user noticed their latest bottle smells odd and the cap changed.

“I’ve been using the Inkey List Niacinamide religiously for about two years and I’ve never smelled that smell before”

Two days into twice-daily use, The INKEY List Niacinamide gave this user itchy red spots, though it seemed to help forehead closed comedones.

“Woke up with itchy red spots after using The Inkey List's Niacinamide.”

After The Ordinary's niacinamide broke out their very oily skin, this user finds The INKEY List Niacinamide pleasant and uses it to hydrate and brighten before tretinoin.

“Inkey List. The ordinary broke me out terribly.”

Prefers its texture to The Ordinary's and says both give basically the same niacinamide results.

“Yes, and I far prefer the texture of the inkey list than the ordinary. Although they both deliver basically the same Niacinamide results IMO.”

Recommends it, saying it sits much nicer on the skin than The Ordinary's.

“Try the Inky List Niacinamide! You have to watch when it’s in stock (Sephora Canada is a bit all over the place), but it sits so much nicer on the skin when compared to TO.”

They are using it in their routine and loving it.

“Also using The Inkey List Niacinamide and loving it!”

A dry-skinned user prefers The INKEY List Niacinamide over The Ordinary's: hydrating and smooth without pilling, though they dislike the packaging.

“I've tried the Niacinamide from both brands and as someone with dry skin I prefer the one from The Inkey List because it's hydrating”
