Are They Dupes?: Sunday Riley Good Genes VS The Ordinary Lactic Acid 10% + HA 2%

a dupe for Sunday Riley Good Genes

Move over, Sunday Riley Good Genes.

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…

Lactic Acid

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 the 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 Do I Need To Know?

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 hare 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 glycerin to hydrate your skin. It’s the most basic of the two options.

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.

I’m so glad you said it isn’t the same because i feel like they are completely different the only similarity is they are both lactic acid and i feel like Good Genes is a more comprehensive treatment whereas the ordinary is just one ingredient.

Andrew, I agree. I wanted to compare them because lots of people are saying they’re dupes but when you look into it, The Ordinary is a basic version of Sunday Riley. If you’re on a budget, it’ll still exfoliate your skin well but you need to supplement the other ingredients with other products.
