Here’s our Sunday Riley Good Genes review. In short: A forever product, shame about the price.  What they say: “An all-in-one AHA treatment, powered by lactic acid, that clarifies, smooths, and retexturizes the appearance of skin.” Our grade: A+ The Sunday Riley Good Genes Review: Honestly, I’d be happier if this didn’t work. I don’t need magical potions that cost between $105 and $158, depending on bottle size — ideally, I would like products that positively affect my mood and are free, like sunshine and starry nights. Alas. Here we are.
