The Ordinary Niacinamide 10% + Zinc 1%, Smoothing Serum for Blemish-Prone Skin, 1 Fl Oz

If you've been searching for a straightforward way to address oily skin, enlarged pores, and uneven texture, you might be overlooking one of skincare's most effective ingredients: niacinamide. This lightweight serum delivers a high 10% concentration of niacinamide (vitamin B3) plus 1% zinc PCA—a pairing designed to tackle blemish-prone skin from multiple angles.

What This Serum Does

The formula is built around two key players. Niacinamide strengthens your skin barrier and helps regulate oil production, while zinc PCA works to minimize pore visibility and reduce congestion. Together, they're designed to deliver visible improvements without unnecessary ingredients or heavy textures.

The water-based formula absorbs quickly, making it easy to layer under moisturizer or other treatments. Most users report noticing changes within the first few weeks of consistent use—oil control can show up in as little as three days, while pore appearance typically improves over four weeks.

Who Should Use It

  • Anyone dealing with excess oil or shine
  • Those with congested, blemish-prone skin
  • People looking to smooth skin texture
  • Those seeking a no-fuss, minimalist skincare step

How to Use It

The application is simple: apply a few drops to clean skin in the morning and evening. Since niacinamide can occasionally cause sensitivity in new users, a patch test on a small area first is wise. Avoid applying to broken or irritated skin, and give the serum time to absorb before moving on to the rest of your routine.

If you're looking for a targeted serum that addresses multiple concerns without unnecessary complexity, this one merits a closer look. Check it out on Amazon to see the full product details and add it to your routine.
