From 14 Reddit threads · Updated November 6, 2026

  2. Dark Spot Correcting Glow Serum

Best Overall Alternative

  • Size: 149.9 ml
  • Price per ml: $0.12/ml (original $2.67/ml)

The why

A watery peptide essence with niacinamide, glycerin, and sodium hyaluronate, designed for damp-skin hydration and smoother layering. It suits oily, dehydrated, or tret-treated routines, though redness, jawline breakouts, and underwhelming long-term results are recurring complaints.

  • Size: 5 ml
  • Price per ml: $0.40/ml (original $2.67/ml)

The why

A 5% niacinamide serum with sodium hyaluronate and squalane, used for stubborn discoloration and a quick dewy finish. Redditors love the light gel and occasional fast payoff, though others see nothing after months or experience breakouts.

Results are wildly inconsistent

#3

Same Active: Niacinamide

  • Size: 30 ml
  • Price per ml: $0.23/ml (original $2.67/ml)

The why

A milky, richer serum built around Centella Asiatica Extract, Niacinamide, Panthenol, and Ceramide NP, aimed at tret-peeling, dehydration, and irritated barriers. Dry or retinoid-treated skin gets the most mileage; acne-prone users may meet clogged pores or pustules.
