Niacinamide 10% + Zinc 1% review
What it does
Niacinamide at 10% is one of the best-evidenced ingredients in skincare for three specific things: regulating sebum, improving the look of enlarged pores, and fading the brown or red marks acne leaves behind. It also supports the barrier, which is why it tolerates twice-daily use.
At roughly 20 cents a millilitre, this is the cheapest properly dosed version on the market.
The texture problem
Be clear-eyed before you buy: this formula is tacky, and it pills. The gums that suspend the niacinamide leave a slightly sticky film, and layering anything over it too quickly produces visible rolls.
Three things reduce it:
- Use three or four drops, not a dropper-full. More product is the single biggest cause.
- Apply to dry skin and press it in rather than rubbing.
- Wait two full minutes before the next layer.
Even done properly it is not as pleasant as a $30 niacinamide serum. That is the trade you are making, and for most people it is the right one.
What to expect, and when
- Week 1-2: less midday oiliness.
- Week 3-4: skin looks more even in photographs before it does in the mirror.
- Week 6-8: post-acne marks visibly lighter.
- Week 12+: the plateau. If nothing has changed by now, niacinamide is not your answer.
Niacinamide does not shrink pores — nothing does, pore size is structural. It clears and de-congests them so they cast less shadow, which is what "smaller pores" means in every advert you have seen.
Where it disappoints
It does very little for deep, sun-driven pigmentation or melasma. It will not treat active inflammatory acne — it manages the aftermath. And at 10%, a meaningful minority of people flush; if that is you, a 5% formula delivers most of the benefit.
Layering
Safe with almost everything. The old warning about not mixing niacinamide with vitamin C comes from 1960s research using pure ascorbic acid under heat, and does not reflect normal use.
