94nextscore· 15 verdicts

Niacinamide-forward serum for glow, redness, and smoother-looking texture; pricey. The catch: $59 is the recurring complaint. Here's what Redditors reach for instead.

The short answer

  1. Niacinamide 10% + Zinc 1%
    Best Overall Alternative

    Oil control and pore shrinkage · $6.00 · 30 ml

  2. Madagascar Centella Asiatica Ampoule
    Best Cheaper Alternative

    Watery, fast-absorbing centella · $6.00 · 30 ml vs $39.00 for the original

  3. Azelaic Acid Hyaluron Redness Soothing Serum
    Best for Redness / Irritation

    10% azelaic acid for redness and breakouts · $22.00 · 30 ml

#1

Best Overall Alternative

  • Size: 30 ml
  • Price per ml: $0.20/ml (original $0.98/ml)

The why

Studies found topical niacinamide helps acne, and Reddit mostly backs that for oil, pores, and red marks. The catch is the 10% strength: lots of users report stinging, flushing, and breakouts, especially on sensitive or already angry skin.

One minus

10% is where the irritation starts for a lot of people

Both recommended for Texture / Pores.

“The Ordinary Niacinamide 10% + Zinc 1% is under $7 and works well for redness on the nose specifically.”

#2

Best Cheaper Alternative

  • Size: 30 ml
  • Price per ml: $0.20/ml (original $0.98/ml)

The why

A watery centella ampoule that people use before moisturizer or tret. It suits irritated, dehydrated, or barrier-damaged skin. On very reactive faces, it can sting, break out, or do basically nothing.

One minus

Can trigger closed comedones or whiteheads

Good forSensitive Skin, Dry Skin

Both recommended for Redness / Irritation.

#3

Best for Redness / Irritation

  • Size: 30 ml
  • Price per ml: $0.73/ml (original $0.98/ml)

The why

Studies found azelaic acid helps acne, and Redditors say this 10% serum is especially good for redness, breakouts, and post-acne marks. It’s lightweight and calming, though some people get stinging, dryness, or a weak response.

One minus

Can sting or burn on a compromised barrier

Good forSensitive Skin, Combination Skin, Oily Skin

Both recommended for Redness / Irritation.

#4

Best for Texture / Pores

  • Size: 50 ml
  • Price per ml: $0.69/ml (original $0.98/ml)

The why

A niacinamide and spicule treatment that Redditors use for acne, texture, and glow. Studies found niacinamide helps acne, and the thread agrees on visible smoothing. Sensitive skin, rosacea, and barrier-wrecked routines often hate the prickly feel.

One minus

Spicules sting, burn, and can wreck a barrier

Both recommended for Redness / Irritation.

“i felt like it actually helped calm down some patches on my cheeks and chin that were constantly inflamed with little deep pimples”
