What Makes It Stand Out

The Ordinary Niacinamide is the best first serum for oily or blemish-prone routines. Niacinamide at 10% is the highest concentration widely available in an OTC serum, and zinc adds sebum-balancing support. The formula does one thing well without overcomplicating a routine.

The lightweight water-based texture layers cleanly under moisturizer and sunscreen. For most oily-skin users, this is the serum that belongs in the routine before they add anything else.

Value

The value is obvious. This is one of the most affordable effective serums available. The only meaningful tradeoff is that it does not hydrate, so it works best as part of a routine that includes a moisturizer.

Pros and Cons

Pros

  • Straightforward niacinamide and zinc formula
  • Lightweight texture layers well under moisturizer
  • Good entry point for serum beginners
  • Works in morning or evening routines

Cons

  • Can feel tacky if too much is applied
  • Not hydrating enough to replace moisturizer
  • Some sensitive users may prefer a lower niacinamide percentage

Bottom Line

The Ordinary Niacinamide 10% + Zinc 1% is a strong Buy for oily and blemish-prone skin. Simple, focused, affordable, and effective as a daily routine serum.
