Kyle Richards’ Favorite Serum Is Nearly 50% Off for Prime Day

Looking for the secret to glowing, glassy skin? Our RHOBH queen Kyle Richards may have just let it slip. The Real Housewives of Beverly Hills star swears by COSRX’s cult-favorite Snail Mucin Power Essence and has even showcased it in multiple Amazon Live shopping streams. Even better, the viral serum is nearly half-off for Prime Day. If you’ve ever been curious about the hype (and trust us, there’s a lot), now’s your moment to score this A-list-loved skincare staple for less.

Packed with 96% snail secretion filtrate (yes, really!), this lightweight essence is beloved for its ability to hydrate, repair and plump without clogging pores or irritating sensitive skin. It’s gentle, glossy and gives that dewy glow celebs can’t get enough of — and with over 67,000 five-star ratings, it’s clearly not just Richards who’s obsessed.

But what exactly is snail mucin, and why is everyone suddenly slathering it on their face? COSRX’s Advanced Snail 96 Mucin Power Essence harnesses the power of this naturally occurring ingredient to deeply hydrate, repair and soothe your skin. Surprisingly, the serum doesn’t feel slimy or sticky at all. Instead, it feels like silky, bouncy goodness that glides on and absorbs fast, leaving behind a gorgeous glow (no residue, promise!).

This K-beauty fave is a multitasking hero, helping to fade dark spots, improve skin elasticity, calm redness and inflammation and support a smoother, plumper-looking complexion. It’s also a dream for skin barrier repair, making it a perfect pick for anyone dealing with dryness, irritation or over-exfoliation. Basically, it’s your skin’s new best friend in a bottle.

The formula is totally gentle and fragrance-free, making it a go-to for sensitive skin types. And thanks to its ultra-light texture, it layers beautifully under serums, moisturizers and makeup without pilling. One shopper even called it “liquid gold” for how quickly it transformed their dull, dehydrated skin.

And here’s the best part: this celeb-loved essence is marked down for Prime Day, making now the time to stock up. Whether you’re a snail mucin newbie or a seasoned skincare stan, this is one glow-up you don’t want to miss. Just ask Kyle!
