If you’re eyeing The Ordinary Niacinamide 10% + Zinc 1% to fight breakouts, start with a patch test.
First, clean a small patch of skin—your jawline works great. Dab a tiny drop of serum onto the area, press it into the skin, and leave it for 24 hours. Watch for redness, itching, or a prickly feeling. If all stays calm, you’re good to go.
Niacinamide, at 10%, helps calm inflamed pores and reduce excess oil, while zinc tames that pesky post‑breakout redness. The blend is lightweight, so it won’t feel heavy or greasy. You’ll notice a subtle, dewy glow after a few days of consistent use.
Remember, a patch test isn’t a license to ignore other signs. If you notice a rash or swelling, ditch the serum and opt for a gentler hydrating lotion. Also, don’t forget to layer it under your moisturizer, not on top of heavy creams.
Grab a 30ml bottle from a local beauty store or order it online. Keep it in a cool, dry spot and shake before each use. Once you’ve cleared the patch test, add it to your nightly routine and watch the magic unfold.
