Questions
Asked about Niacinamide 6% Fluid
Why 6% and not 10% or 20%?
Because 6% is in the range the published evidence supports for oil control, the look of pores and uneven tone. Higher percentages have not been shown to do more, and they are the ones known for flushing. Higher percentages are marketing, and the carton says so.
What does the zinc PCA do?
Zinc PCA at 1% is included for oil control. It is the second active on the label.
Can I use it with vitamin C, acids or retinoids?
Yes. It is safe with acids and retinoids on alternate steps, and it sits at pH 5.8–6.2. Apply it after cleansing and let it absorb before the next product.
I flushed with a 10% niacinamide. Will this do the same?
It is dosed lower on purpose, and the flush is associated with higher percentages. We cannot promise how your skin will react, so patch test on the inner forearm for 24 hours first.
When will I see a difference?
In our 8-week study, the measured change in surface oil was at week 8, not week 1. Give it at least four weeks of steady use before judging it.
Is it fragrance-free?
Yes. The list is short on purpose: niacinamide, zinc PCA, glycerin, panthenol and the ingredients needed to keep the fluid stable.

Oily, reactive
No flush at 6%
A 10% niacinamide made my face flush. This one at 6% never has, and my forehead is noticeably less shiny by the afternoon.

Pores on my nose look smaller
Two months in. I know pores do not actually shrink, but they look less obvious and my makeup sits better.

Works slowly
Nothing for a month, then I noticed I was blotting less. Worth knowing it takes time.

Combination, post-blemish marks
Marks from old breakouts look less obvious
I use it morning and night. The leftover marks on my cheeks look more even than they did in spring.

Honest marketing for once
The carton literally says higher percentages are marketing. I bought it for that sentence and stayed for the result.

Fine, not dramatic
It is a good, gentle serum. On my dry skin I did not see much change, though I am probably not who it is for.

Layers with everything
Goes under my moisturizer and sunscreen with no pilling at all.

Runs out quickly at twice a day
I love it, but at half a dropper morning and night the bottle lasted me about seven weeks. Once a day stretches it.

Less shine by 3 pm
I work under studio lights and I can see the difference on camera.

Gentle on redness-prone cheeks
My cheeks look calmer and nothing stings. Simple formula, no scent.
