Purito TXA 6 Niacinamide 10 Retinal Serum Dupes & Cheaper Alternatives

From 4 Reddit threads · Updated October 27, 2026

Six-percent tranexamic acid and retinal target dark spots; retinal strength feels underwhelming. The catch: retinal dose feels too low for experienced users. Here's what Redditors reach for instead.

The short answer

  1. Niacinamide 10% + TXA 4% Serum
    Best Overall Alternative

    10% niacinamide + 4% tranexamic acid brightening combo · $21.85 · 29.9 ml

  2. Madagascar Centella Probio-Cica Intensive Ampoule
    Best Cheaper Alternative

    Barrier-support serum for tretinoin peeling · $6.99 · 30 ml vs $12.90 for the original

  3. No.5 Vitamin Concentrated Serum
    Same Active: Niacinamide

    Tranexamic acid plus niacinamide for dark spots · $17.00 · 29.9 ml

#1

Best Overall Alternative

  • Key actives: Niacinamide 10%, TXA 4%
  • Size: 29.9 ml
  • Price per ml: $0.73/ml (original $0.43/ml)

The why

A 10% niacinamide and 4% tranexamic acid serum targeting dark marks, with arbutin and multiple hyaluronic acid forms. Redditors report impressive fading, while studies found 10% niacinamide can reduce pimples; sensitive, acne-prone users report breakouts and barrier damage.

One minus

Sticky, slow-absorbing finish that sits on skin

#2

Best Cheaper Alternative

  • Size: 30 ml
  • Price per ml: $0.23/ml (original $0.43/ml)

The why

A milky, viscous ampoule combining Centella Asiatica Extract, Niacinamide, Panthenol, and Ceramide NP for irritated, dehydrated skin. Tretinoin users reach for it after peeling or over-exfoliation, though ferments and richer emollients can trigger breakouts.

One minus

Breakouts, whiteheads, or clogged feeling hit some users

Good forDry Skin, Sensitive Skin

#3

Same Active: Niacinamide

  • Size: 29.9 ml
  • Price per ml: $0.57/ml (original $0.43/ml)

The why

This multi-active brightening serum pairs tranexamic acid, niacinamide, and several vitamin C forms for uneven tone and post-acne marks. Redditors report fading, while studies support niacinamide for acne; breakout-prone skin may react, and the vitamin C payoff is modest.

One minus

Breakouts, including cystic acne, hit some users

Good forSensitive Skin, Dry Skin
