  • Great product, worth the price
Size: 1 Fl Oz (Pack of 1)
Love it! Noticed visible difference in dark spots, and face was just noticeably better! Ordered on sale on Black Friday, and just got my second bottle today!

  • Five stars!
Size: 1.7 Fl Oz (Pack of 1)
I’m in love with Sunday Riley’s Good Genes. From the first use, it was like magic—my pores were clear overnight. If you overuse it, it can cause a bit of dryness, but I use it 2-3 times a week because I have oily skin—and it’s marvelous. I haven’t found another product with similar results. I’ve tried many Elemis products, which are top quality but too gentle for me. Personally, I want strong, fast results, and those ultra-gentle products do nothing for me. Good Genes is magnificent—worth every penny. I tried a mini version in a set and ended up buying the full-size. I finished it and want more—it’s irreplaceable. Five stars! ... show more

  • Holy smokes this is GOOD 🔥
Size: 0.5 Ounce (Pack of 1)
Whoah!! I purchased this on a Black Friday sale to try something new. It arrived today and I literally saw big results within minutes. This is my best purchase of the year. Holy crap this stuff is good. I have no ties to the brand whatsoever. I typically use “the ordinary” brand (which is good too but this has me in awe). ... show more

  • LOVE!!
Size: 0.5 Ounce (Pack of 1)
Expensive but so worth it! I love the depuffing and the way it makes my skin look luminous and supple!

  • I hate that this works so well
Size: 0.5 Ounce (Pack of 1)
I hate it because it’s so damn expensive but oh well. I’ve tried other lactic acid products and they either make my skin red or lead to breakouts. The Sunday Riley one is the only one I’ve ever found that makes my skin just look… perfect. I don’t use it daily, just before days where I will be wearing makeup or want my skin to look flawless. It’s a noticeable difference the next morning if I use it as the first step of my nightly skincare. The packaging really does suck though, there’s so much product left in the little packet thing that you have to cut it open and use it that way. ... show more

  • After a long career trying out every beauty serum, this is one of my must-haves
Size: 1.7 Fl Oz (Pack of 1)
I don't generally consider myself to be a superstitious person, and yet I have bought this (let's be honest:) absurdly expensive exfoliating serum more than a dozen times over the past several years. There's just something about it that makes me feel—nay believe—that a big part of my having much clearer, better-textured skin than I did ten years ago is at least to some extent attributable to this serum. First of all, this just feels very, very good to use. The product is neither heavy/greasy, nor is it overly thin or watery - you can almost feel it sinking into your skin as you apply it. Unlike many chemical exfoliants (glycolic acids have generally been my go-tos), I've never experienced any stinging or even temporary redness after applying this—even in mid-winter, when my face is otherwise dull, flaky, and mercurial. Instead, from time to time I'll feel a not at all unpleasant gentle tingling that ebbs away in seconds. Finally, it has an almost imperceptible pleasant, wholly natural-seeming scent. All in all, as a chronic skincare overspender, I very much believe that this product, moreso than any other I've tried in my endless quest to find the holy grail of facial maintenance, has been *extremely* thoughtfully formulated. For me, the only downside is how almost insultingly expensive this product is; however, it is a beauty serum, not a bottle of ketchup, so hate the game, not the player. Plus, if you use a single pump each day (which is absolutely adequate), a bottle will last long enough to give you time to get over your consternation over how much it cost. Of course, then there's the fresh dismay over how much you'll have to shell out for another bottle... ... show more

  • Gives youthful glow, brightens and shrinks pores

I love this stuff ! Wish I would have tried sooner! Makes my skin look brighter and smoother. Adds more youth to the look of my face .

  • A must have product for me.
Size: 1 Fl Oz (Pack of 1)
I really love this product! I do layer it over Sunday Riley's Luna Sleeping Night Oil. Once I apply Good Genes over the oil there is a burn that isn't painful but you can feel it working. And then I put a moisturizer over it. Even the first morning after I started this routine again my skin felt so soft. There was a noticable difference. It helps with fine lines and overall radiance. It's a product I don't not like to go without. ... show more
