Best Sunday Riley Good Genes All-In-One Lactic Acid Treatment Alternatives: Verified Quality Match (2026 Tested)

Our Verdict

Good Genes is really two things: lactic acid, and an unusually elegant emollient-lotion delivery that feels like a serum-fluid. Most 'dupes' nail the acid and miss the feel. Naturium's Vegan Lactic Acid Emulsion is the rare one that gets the creamy-lotion texture closest — at under a third of the price — though at a gentler 5% strength. The Ordinary Lactic Acid 10% + HA is the cheapest way to get more lactic acid, but it's a thin, slightly tacky liquid, a very different format; The INKEY List's 10% serum is similar. If you love Good Genes specifically for how it feels under makeup, the Naturium is the closer match; if you just want lactic acid, the $9 Ordinary does more for less.

Choose the Luxury if…

You want Good Genes' specific purified-lactic-acid lotion that absorbs like a smooth fluid and layers cleanly under makeup.

Choose the Duplixo Pick if…

You want the creamy lactic-acid lotion feel for less (Naturium), or simply more lactic acid at the lowest price and don't mind a thin serum texture (The Ordinary).

Quick Answer

Naturium's Vegan Lactic Acid Emulsion 5% is the closest texture match to Good Genes — a creamy, milky lactic-acid lotion that sinks in without tackiness, at $25 vs $85. For a stronger, cheaper active hit, The Ordinary Lactic Acid 10% + HA ($9) delivers more lactic acid but in a thin, tacky liquid that feels nothing like Good Genes' lotion.

Sunday Riley Good Genes is a purified-lactic-acid treatment in an emollient lotion base with squalane and licorice root — it applies like a smooth cosmetic fluid that absorbs without tackiness.

Editor's Testing Note

Lactic acid is a commodity active, so the real differentiator is delivery. Good Genes uses a purified lactic acid in an emollient lotion with squalane and licorice, which is why it feels like a cosmetic fluid rather than an acid. The Ordinary and The INKEY List both offer more lactic acid (10%) but as thin, water-based, slightly tacky liquids — same active, very different experience (hence their mid scores despite higher strength). Naturium's Vegan Lactic Acid Emulsion scores highest here because it matches the creamy-lotion format closest, even at a gentler 5%. Pick on whether you're buying the acid or the feel.

Frequently Asked Questions About Sunday Riley Good Genes All-In-One Lactic Acid Treatment Dupes

What is the best Sunday Riley Good Genes dupe?

It depends what you want. Naturium's Vegan Lactic Acid Emulsion 5% ($25) is the closest texture match — a creamy lactic-acid lotion like Good Genes. The Ordinary Lactic Acid 10% + HA ($9) is the cheapest and stronger on acid, but it's a thin, tacky serum, a very different feel.

Is The Ordinary Lactic Acid the same as Good Genes?

Same active (lactic acid), very different format. The Ordinary is a thin 10% liquid that stays slightly tacky; Good Genes is an emollient lotion that absorbs like a smooth fluid. The Ordinary does more exfoliating for far less, but it won't feel like Good Genes.

Which alternative feels most like Good Genes under makeup?

Naturium's Vegan Lactic Acid Emulsion — its creamy lotion texture sinks in without tackiness, closest to Good Genes' fluid-like feel, though at a gentler 5% lactic acid.
