The brains behind the Glass Skin Refining serum that sells every three minutes (and sold out literally a dozen times) is back with a new skin-care hit—just in time to help us combat dry, flaky winter skin. Peach & Lily Power Cocktail Lactic Acid Repair ($49), which launched December 15, refines your complexion in a New York minute: The powerful (yet gentle) formula contains 10 percent lactic acid and 12 active extracts that work overtime to smooth out fine lines, even out texture, boost brightness, and pump up the hydration.

I was able to test the Power Cocktail serum for a couple weeks before launch, and am so in love with the results. My skin feels softer, and my complexion has been so clear that I've been skipping foundation all together. Applying it at night and in the morning, I've noticed that the serum truly has blurred the fine lines on my forehead and around my mouth—and even if this is only temporary, I'll take it. Aside from giving me a more radiant complexion and barrier protection as the temps dip and indoor heating slurps all the hydration from my body, I also love that the formula plays nice with other products I use (i.e. it doesn't pill when paired with moisturizers or makeup). It absorbs quickly, feels silky-smooth, and doesn't ever leave a sticky or greasy texture behind.

So, what makes this stuff so good? The most praise-worthy ingredient is the lactic acid, an alpha-hydroxy acid (AHA), which gently exfoliates and resurfaces skin. This sloughs away dead skin cells, banishing flaky or scaly-feeling surfaces, helps soften fine lines, and is instrumental in helping fade away dark spots. Using serums with AHAs "reveals rejuvenated and brighter skin," dermatologist Dennis Gross, MD, previously told us.

But that's not all. Thanks to the formula's panax ginseng root extract (an antioxidant that helps renew skin), red algae (this helps with firmness), gingko biloba (another antioxidant that fights inflammation), botanical ferment complex (a probiotic that protects the skin's barrier), ceramides (another ingredient that acts as a skin barrier shield), and hyaluronic acid complex (basically a tall glass of water for your skin that leaves it supple and more elastic), there's not a lot this serum can't offer, TBH. It's truly the whole package.

Anyway, don't just take my word for it. The early reviews are in, and they're all glowing. "I'm really surprised by this serum. I was sent this as a gift to try with a request to leave a review. I wasn't expecting the results I've seen so far," one reviewer wrote. Another wrote: "I [look like I] just got a facial. My family has already commented and noticed. The really spectacular part is the tightening! I am so happy with my results and see that my skin looks firmer and younger."

Another said, "After only a few applications I am already seeing a difference in my skin. The serum leaves my skin feeling silky smooth and visibly looks more radiant. Excited to see the result after more uses! So far I am loving it!"

Do your face a favor and get a bottle.
