P.S. The Famous Sunday Riley Good Genes Lactic Acid Treatment Is 20 Percent Off

Fact: No single regimen works perfectly for everyone. But every once in a while, a product is so good that it fits into almost everyone's skin-care routine.

We're talking about Sunday Riley Good Genes. Technically a serum, this anti-aging treatment is formulated with five percent lactic acid to slough off dead skin cells, clear your complexion and boost collagen production. Plus, it's gentle enough for most skin types, which is a big reason why countless people, including five PureWow editors, swear by it.

Some of us use it in the morning to blur imperfections, while others slather it on before bed to help regenerate skin cells overnight. Any time one of us gets a sample of the wrinkle-reducing elixir sent to us to test, our entire team starts a conversation about how much we love the product (OK, and how much it smells like Pez—remember the candy?).

As you can imagine, we're all elated that Dermstore is slashing up to 20 percent off Good Genes during their spring savings event. Meaning you can get a full-size bottle for as low as $68 when you use coupon code SUN at checkout. The sale lasts until May 31, but things are already selling out, so you'll want to add this to your cart ASAP. Still need more convincing? Read our editors' glowing reviews below.

"To convince you of Good Genes’ greatness, I could tell you about how it makes my skin look glowier and plumper in a matter of minutes. Or I could tell you about how, over time, it’s evened out my skin tone and made it feel softer than ever. But most importantly, it smells like Pez, and that should be reason enough to try it." —Sarah S., Senior Editor

"I don't use it every day, but I definitely reach for it on those mornings when my skin looks dull and needs an instant pick-me-up. I also love how it absorbs quickly, so I can easily layer it under the millions of other creams and serums I apply in the A.M." —Dena S., Fashion Editor

"I've used Good Genes for years and found it to be one of the most hydrating and brightening products!" —Katherine G., Associate Food Editor

"I'm a new convert to Good Genes after hearing rave reviews from my coworkers. I've only been using it for a few weeks now, but I feel like my skin has definitely changed for the better—it's smoother and more even-toned. The formula isn't sticky or drying at all, and it smells like candy." —Rachel G., Associate Managing Editor

"The best product that has come across my desk in the last two years? Sunday Riley Good Genes, hands down. It was the first lactic acid I tried, and I honestly feel like I hit the jackpot. It smooths my skin like nothing else, and the creamy consistency feels more like a moisturizer than a watery serum, so I never have to worry about the acid drying out my skin too much. ILY Good Genes, never change." —Brianna L., Commerce Editor
