As someone with sensitive skin, I know all too well the struggle of finding a middle ground between effective formulas that won't cause irritation. In the world of skincare, too much of a good thing is definitely possible, which is why you need to pay close attention to the actives you're applying to your skin. Niacinamide is one of those unicorn ingredients that boasts a variety of benefits—without aggravating my skin.

"Niacinamide reduces sebum production, which can both help prevent acne and also diminish shine," board-certified dermatologist of UnionDerm in New York City, Kenneth Howe, MD, previously told Real Simple. Moreover, it reduces inflammation, strengthens the skin barrier, and brightens the complexion. That's precisely why I can't get enough of the Cosrx Niacinamide Face Serum. You may recognize the Korean brand for its iconic Snail Mucin Essence, but it offers an array of high-quality skincare formulas at affordable prices, and even TikTok has noticed. The serum normally costs $25, but you can get it for just $14 at Amazon today.

COSRX Niacinamide 15% Face Serum





Along with 15 percent niacinamide, the serum is packed with allantoin, n-acetylglucosamine (NAG), and zinc PCA, which work together to refine your skin pores for clear skin, improve hyperpigmentation and texture, and treat blemishes with noticeable results in four weeks. I've been using the serum since late September to help with my sporadic breakouts, and it's become a staple in my nighttime routine. It only takes a few minutes for the lightweight formula to absorb into my skin, so I can quickly apply my moisturizing cream on top without any greasiness or residue.

I didn't experience any irritation from day one. My pesky dark spots gradually faded in just a few weeks, and my T-zone is less shiny. It always leaves my face feeling so soft after I apply it. I've also experienced far fewer breakouts than usual, which is always a major win in my book, especially with all the social events I've been attending recently. The Niacinamide Face Serum is an affordable option that I'll be keeping in my beauty cabinet from now on.
