Fans of this popular spray serum say that it gives them “glass skin” and is easy to apply. Something else to know: It has had a rollercoaster summer, with its price bouncing up and down more than once. Right now, the D’Alba Piedmont Italian White Truffle Spray Serum is down again and you can get it for 38% off at Amazon. If you’ve been waiting for the right moment to grab it, this favorite may not stay this low for long.

Deal of the day

The D’Alba Piedmont Italian White Truffle Spray Serum has built a loyal following for its lightweight, mist-on formula that makes skincare feel almost effortless. Infused with white truffle extract, the serum is designed to hydrate, brighten and smooth the skin while delivering a boost of antioxidants. One shopper even calls it “glass skin in a bottle,” and says the serum offers an instant glow and hydration without feeling heavy or leaving residue.

Unlike traditional serums that require you to massage product into your skin, this spray format lets you mist it on your face (or even over makeup) for a quick refresh throughout the day, making it a favorite for people who want visible results without adding extra steps to their routine. Beyond convenience, the serum is non-comedogenic, meaning it’s designed not to clog pores, and it’s gentle enough for daily use across most skin types. Right now, the serum spray is 38 percent off, bringing the price down to under $20.
