Skincare junkies and celebs alike have been raving over Sunday Riley products for years now, particularly the brand’s Good Genes Lactic Acid Treatment.

Just a few pumps of the serum applied to the skin each day helps with smoothness, discoloration and brightness, making the Good Genes Lactic Acid a must-have in your skincare kit.

Now, a new Amazon deal gets you two bottles of the best-selling serum for almost the price of one, with this “win win” duo kit on sale for just $85. The kit includes two sizes of the Good Genes treatment serum, in 15 ml. and 30 ml. bottles. It’s an incredible value considering a single bottle of the serum retails for $76 on Amazon.com.

This is one of the best-reviewed Sunday Riley products online, with a current 4.6-star rating (out of five) from thousands of verified reviewers online. The skincare brand says its Good Genes serum is “proven to immediately and significantly plump fine lines and boost radiance in just three minutes.”

In our experience, it’s helped to refine our rough skin and reduce wrinkles, while working to tighten and tone as well. The result: smoother, more radiant-looking skin. Though it’s billed as a “lactic acid,” the serum is super gentle and non-irritating, even on our sensitive skin.

Sunday Riley says it uses clinically-proven ingredients blended with “balancing botanicals” to help achieve results. In this case, the Good Genes formula includes licorice root, which helps to brighten skin, and lemongrass, which has astringent properties that help it work as a toner. The product is also double certified as cruelty-free by both PETA and Leaping Bunny. 

Regularly $75.98 for a single bottle, you can get two bottles of Sunday Riley’s Good Genes All-in-One Lactic Acid Treatment Face Serum right now for just $85. How we use it: keep one bottle at home and one in your toiletry bag for travel.

As with all Amazon offers, pricing can change at any time so we recommend adding this Sunday Riley deal to your cart now. See full details here.
