The Ordinary Niacinamide 10% + Zinc 1% is a targeted serum designed for blemish-prone and congested skin. It combines a high concentration of Vitamin B3 with Zinc PCA to tackle excess oil, dullness, and visible pores, making it a go-to for anyone struggling with uneven texture or frequent breakouts.

In real-world use, this serum delivers noticeable improvements in skin radiance and smoothness within seven days. The lightweight, water-based formula feels refreshing and absorbs quickly, while the inclusion of Zinc helps calm active oiliness after just a few days. Over four weeks, pores look tighter and skin appears less congested, backed by clinical testing referenced by the brand.

The build quality is consistent with The Ordinary's minimalist approach: a simple dropper bottle that dispenses the right amount, and a clear, slightly viscous liquid that layers well under moisturizers or sunscreen. There are no unnecessary fragrances or oils, which is a plus for reactive skin types.

On the downside, the 10% niacinamide concentration is potent and can cause stinging or flushing for sensitive users. A patch test is strongly recommended, and it should never be applied to broken skin. Additionally, the 1 oz bottle may run out faster if you apply it to the whole face twice daily, though the low price makes repurchasing easy.

Overall, this is a high-performing, budget-friendly serum that delivers on its promises for most skin types. If your skin tolerates niacinamide well, it is a worthwhile addition to a daily routine for smoothing texture, controlling shine, and improving overall clarity.

One potential drawback is that the serum works best when applied to damp skin and followed by a moisturizer, which adds an extra step. Additionally, at the time of writing, there are no customer reviews, so long-term efficacy is based on the brand's reputation and ingredient transparency rather than real-world feedback.

Start by applying 1 to 2 drops to clean, dry skin once or twice a week. Gradually increase to up to 5 drops per use as your skin builds tolerance.
