I envy babies for two reasons: One, they have the luxury of lounging in strollers, often asleep, while the rest of us are pounding the pavement, often wired (yet, somehow, still exhausted). Two, their complexions look like silk and feel like velvet — without any help from a 10-step skincare routine. 

Interestingly, babies’ skin contains ample squalene — a softening lipid we’re born with and gradually lose as we age. Luckily, squalane — a vegan version touting similar properties — is at our disposal, via serums and moisturizers spiked with the stuff. As for the Amazon shopper-loved Numbuzin No.3 Skin-Softening Serum (which more than 5,000 people have bought in the last month, per the retailer), squalane is only one of the many suppleness-inducing skincare ingredients. 

Hailing from a Korean skincare brand, the Numbuzin No.3 Skin-Softening Serum is a highly soothing, lightweight solution for dry, rough skin and uneven texture. The formula supports a glass skin look thanks to its smoothing effect and its pore-refining prowess. Texturally, the serum is somewhere between watery and milky, and it incorporates seamlessly, sans pilling, into virtually any existing skincare or makeup routine. 

The secret to the serum’s skin-softening success are ingredients like niacinamide and panthenol. Both forms of vitamin B — B3 and B5, respectively — they’re well-tolerated by most skin types, and can make a profound difference in texture. Squalane, as previously mentioned, is also in the mix, and locks in moisture to further support baby-like softness. Each of these hero ingredients is backed by ample acclaim from dermatologists — many of whom tout benefits beyond skin-softening. 

Niacinamide, for instance, can help reduce the appearance of hyperpigmentation and can improve skin texture over time, dermatologist Dr. Hadley King, MD, previously shared with InStyle. Panthenol, an excellent hydrator, can help reduce roughness and flakiness associated with dry skin. Furthermore, it offers anti-inflammatory benefits, which soothe sensitized skin and, consequently, can help reduce redness.

It’s no wonder the serum has racked up more than 1,100 five-star ratings. According to one reviewer, who said they’ve seen “amazing results” using the Numbuzin No.3 Skin-Softening Serum, it’s soothing, even on “irritated or peeling skin.” Plus, they say it delivers a “healthy glow without greasy shine.” Another shopper who has sensitive, rosacea-prone skin, called the formula “magic in a bottle” thanks to how it “greatly reduced [their] visible texture.” “My skin was going through some terrible texture and dryness issues [and] this helped so much,” said another customer. “My skin is back to how it used to be.”
