Glowy Skin Is My Bread and Butter—This Brightening Serum Is Like an IV Drip for My Complexion

My signature beauty look isn't a flick of winged liner or fluffy, brushed-up brows. It's a healthy, megawatt glow. I'm talking about skin so radiant that people ask me where I just went on vacation or what highlighter I've glazed across my cheekbones when I'm not even wearing one. When my skin is glowing, every other aspect of my beauty routine just falls into place.

There's just one teensy problem: My skin can't tolerate vitamin C, which is considered one of the classic skin brighteners. Every time I use it, I'm met with clusters of breakouts on my T-zone and patches of irritation on my cheeks. (Before you ask, yes, I've tried multiple forms of vitamin C, and yes, I still wind up with the same results.) I had a hard time accepting this fate given that vitamin C is such a dermatology darling, but after much trial and error, I've decided to officially forgo the vitamin C serums. If vitamin C does work well for your skin, feel free to check out these editor-vetted formulas and know that I'm very jealous.

That doesn't mean I've sacrificed a glowy visage. It's quite the opposite, in fact! My inability to tolerate the ingredient has given me all the more drive to discover the best skin-brightening serums on the market. I think I've done a pretty great job if I do say so myself, so I'm sharing my picks below along with some derm-backed tips for luminous skin.

FAQ

What should I look for in a brightening serum?

It ultimately depends on the specific concerns you'd like to address. If dark spots are your main gripe, Yadav recommends vitamin C (unless you're sensitive to it like me), tranexamic acid, licorice extract, and niacinamide. "Vitamin C, tranexamic acid, and licorice extract are what's known as tyrosinase inhibitors, working to block the enzyme your skin needs to create melanin and reducing discoloration," she explains. "Niacinamide prevents melanosome transfer, which is another important aspect of treating dark spots—melanosome transfer is when the pigment is moved into your skin cells, causing discoloration."

Now, let's say you simply want to brighten dull, sallow skin. "For overall skin brightening, I'd recommend ingredients like alpha hydroxy acids (such as glycolic, lactic, and mandelic acids), beta hydroxy acids (such as salicylic acid), azelaic acid, retinol, and bakuchiol. These ingredients all promote cellular turnover," Yadav notes. "When the dull skin on the surface is removed or sheds on its own, the complexion appears brighter overall."

What's the best brightening serum for my skin type?

If you have sensitive skin, Yadav recommends seeking out bakuchiol, licorice extract, and niacinamide. "They are known for being very gentle as well as effective. They all offer anti-inflammatory properties that make them ideal for reactive skin," she notes. You'll also want to make sure your brightening serum has enough hydrators and emollients to cushion the skin against any potential irritation. Those with sensitive skin should look for hydrators and emollients that will help keep the skin nourished and comfortable. Acne-prone skin types should consider water-based serums, which are less likely to contain heavy oils that could congest the skin.

If you have oil- or acne-prone skin, bakuchiol and niacinamide will also work well. Yadav also suggests finding a serum with beta hydroxy acids to simultaneously address blemishes and brighten the skin. "Acne-prone skin types should consider water-based serums, which are less likely to contain heavy oils that could congest the skin," Yadav adds.

Do brightening serums really work?

"Yes, brightening serums really work, but the majority of skincare products take time and consistency to see results," declares Yadav. One more time for the people in the back: Skincare is an investment, and no brightening serum, no matter how sophisticated, will give you overnight results. With patience and consistency, however, you can surely see your complexion transform before your eyes.

"If you've been lax about exfoliating in the past, a brightening serum that works via exfoliation (using AHAs, BHAs, or azelaic acid) may give you visible results after one use, but generally speaking, it takes four weeks to see some results from most skincare products," Yadav continues. "It will likely take longer, possibly much longer, to see a change in stubborn dark spots, but consistency is key!"
