a dupe for Sunday Riley Good Genes

Move over, Sunday Riley Good Genes (US version. The EU version has Glycolic Acid).

There’s a new lactic acid exfoliant in town. It’s called The Ordinary Lactic Acid 10% + HA 2% and is wayyyy cheaper than you. Cos you shouldn’t need to sell a kidney for good skin, know what I mean?

But… if the dupe’s so cheap, can you trust it to work as well? Only one way to find out…

What Ingredients Do These Lactic Acid Exfoliants Have In Common?


Both Sunday Riley Good Genes and The Ordinary Lactic Acid 10% + HA 2% use lactic acid, the gentlest member of the AHAs family.

Yep, the same family as glycolic acid. Both lactic and glycolic do the same things:

The difference? Glycolic acid’s bigger than lactic acid. And here size matters. A lot.

The small size of glycolic acid allows it to penetrate skin more easily. That makes it more effective, BUT also more irritating.

That’s why lactic acid is so perfect for sensitive skin. Out of all the AHAs, it’s the one less likely to irritate your skin.

Just one thing: Lactic acid is the second ingredient in The Ordinary Lactic Acid 10% + HA 2% and the 6th in Sunday Riley Good Genes. 

You guessed it, there’s a lot more lactic acid in The Ordinary product than in the Sunday Riley one. That makes Sunday Riley the gentlest option. But also the least effective (when it comes to exfoliation, at least).

What Else Is In These Lactic Acid Exfoliants?

I wouldn’t call Sunday Riley Good Genes and The Ordinary Lactic Acid 10% + HA 2% dupes. Lactic acid is the only thing they have in common!

Sunday Riley also has its fair share of antioxidants and soothing ingredients to fight wrinkles and help calm down redness and irritation.

The Ordinary only has tasmania pepperberry to reduce irritations. Plus hyaluronic acid to hydrate your skin. It’s the most basic of the two options.

What’s The Texture Like?

The Ordinary Lactic Acid 10% + HA 2% has watery gel texture that absorbs easily. It’s runny, so it makes application a little tricky.

Sunday Riley Good Genes has more of a lightweight lotion texture that glides on smoothly on the skin.

What’s The Packaging Like?

The Ordinary Lactic Acid 10% + HA 2% comes in a see-through white bottle with a dropper applicator. Be careful when you apply it cos the serum will run down all over your face.

Sunday Riley Good Genes comes in a white, see-through bottle with a pump applicator. Sleek and practical.

How To Use Them

One or two nights a week, after cleansing.

Which Of The Two Should You Go For?

That’s up to you. If money isn’t an issue, your skin doesn’t need much exfoliation, and you want the full package (antioxidants and all that jazz), investing in Sunday Riley Good Genes makes sense.

If you’re on a budget, want results faster or simply don’t want to sell a kidney to buy an exfoliant, The Ordinary Lactic Acid 10% + HA 2% will do the trick just fine.

But I do recommend you start with the gentlest version, The Ordinary Lactic Acid 5% + HA 2% and upgrade to its bigger siblings after a few months.

Remember the rule of exfoliation: start with the smallest concentration you can find and build up dose overtime.

Is The Ordinary Lactic Acid 10% + HA 2% A Dupe For Sunday Riley Good Genes?

I wouldn’t call The Ordinary Lactic Acid 10% + HA 2% a dupe for Sunday Riley Good Genes. It’s a much more basic version. But if gentle exfoliation is all you’re after, it’ll do the job just as well.
