The dupes, ranked by effectiveness

The short answer
Each of these is ranked against the Good Genes Lactic Acid Treatment original. "Effectiveness" means the percentage of the original's benefit the dupe actually delivers, not just ingredient similarity.

Dupe #1 · 75% of the original

Naturium AHA Exfoliating Mask 10%

~$16
vs ~$120

Why it works: 10% AHA blend including glycolic and lactic acids in a weekly mask format. Near-clinical exfoliation at a mid-tier price.

Where it falls short: Weekly mask, not a daily serum. No supporting brightener (Good Genes has licorice).

Best for: Stronger weekly resurfacing without the Good Genes price

The honest verdict

The short answer
The $122 Good Genes is genuinely good, the licorice + arnica blend does add gentle brightening on top of the lactic acid. But for most people, The Ordinary Lactic Acid 10% + HA at $8 delivers ~70% of the result for under 7% of the cost. Splurge only if you specifically want the licorice/arnica/lemongrass complex AND love the texture.

Frequently asked questions

Frequently asked

What is the best Sunday Riley Good Genes dupe? +

The Ordinary Lactic Acid 10% + HA at $8 is the best Good Genes dupe. It uses 10% lactic acid (slightly higher than Good Genes 7%) with hyaluronic acid for hydration, at 1/15 the price.

Is there a Sunday Riley Good Genes alternative under $20? +

Yes, The Ordinary Lactic Acid 10% + HA ($9), The Ordinary Lactic Acid 5% + HA ($8), and Naturium AHA Exfoliating Mask 10% ($16) all deliver AHA-based brightening at under $20.

Is Sunday Riley Good Genes worth the price? +

For most buyers, no. The $8-18 lactic acid alternatives deliver the same hero ingredient at 7-15% of the cost. Splurge on Good Genes only if the licorice/arnica/lemongrass blend (the supporting actives) makes a visible difference for you.

Does lactic acid bleach skin? +

No, lactic acid does not bleach skin. It exfoliates dead cells and stimulates cell turnover, which evens skin tone over weeks. Any "brightening" effect is from removing dull surface cells, not bleaching pigment.

How long does it take Good Genes to work? +

Immediate glow within 1-2 uses; visible brightening at 2-3 weeks; significant tone improvement at 6-8 weeks. The cheaper lactic acid dupes follow the same timeline.
