We all know (and love) what strategically placed highlighter or a touch of bronzer can do. That lit-from-within glow that products can instantly provide has been the focus of many articles and makeup lines—and for good reason. It can transform you into an effervescent goddess, distract you from imperfections, and, perhaps most importantly, make it look like you really did get a full night of beauty sleep. But what if instead of creating that glow with makeup, you could wake up with naturally radiant skin?
Enter illuminating, radiance-boosting serums; your key to getting the perfectly toned, even skin that we all dream about.These formulas (which often contain potent antioxidants like vitamin C) can help diminish dark spots, refine skin texture, and create an overall luminous complexion. By adding this one step to your routine (after cleansing but before moisturizing), youll never have to rely solely on makeup to hide imperfections and deliver the glow you want.
With claims like these, its no wonder that almost every brand has a stake in the radiance-boosting realm. To help you choose which illuminating serum will be your new holy grail,we researched the best ones on the market,assessing their ingredients and claims. After consulting with Dr Ife J. Rodney, MD, a board-certified dermatologist and the founder of Eternal Dermatology in Fulton, Maryland,and considering dozens of options, we landed on these top-rated choices.

Contains a high percentage of vitamin C
Also contains exfoliating PHAs
Pump bottle dispenses the perfect amount

It may be the eye cream from this Banana Bright line that gets all the attention, but don’t sleep on this serum. Along witha potent amount of illuminating vitamin C, it contains exfoliating PHAs (polyhydroxy acid) and hydrating and plumping hyaluronic acid,too. We were big fans of the pump top bottle that dispensed the perfect amount and how well it hydrated our skin while alsoimparting plenty of glow. It also isn’t sticky or tacky and layers really nicely under other skincare products.
Who It’s For
Almost anyone can benefit from this multi-tasking formula, which actually addresses a variety of complexion concerns. Just take note that it may cause a bit of irritation if you have sensitive skin.

Easy to apply
Lightweight application
Affordable
Great for sun damage
Has a sticky feel
Coming in as our best-budget buy, this serumpacks a huge punch without breaking the bank. Its formulated with a 2% concentration of alpha arbutin,a powerful skin illuminator known for being gentler than its counterparts.1“This is a naturally occurring skin-tone evener that blocks the enzymes responsible for melanin production,” explains Rodney. The ingredient issupported by hyaluronic acidand slowly releases for an enhanced delivery, which sets it apart from other illuminating serums. We found it to be a game-changer, especially when used as part of a cohesive skincare routine.
Who It’s For
This is a great choice for anyone on a budget, as well as if you have dry skin,as its not as harsh as its counterparts, thanks to the use of alpha arbutin.
Benefits: Reduces the appearance of dark spots and uneven skin tone | Skin Type:All | Dosage: Twice a day | Size: 1 oz. | Cruelty-Free: Yes

Has a bit of an unpleasant smell
No list of our favorite serums would be complete without this offering from SkinCeuticals. We have sung its praises time and again. As its moniker suggests, itsa magical blend of vitamins C and E, plus ferulic acid that helps to transform and even skin tone both instantly and over time, leaving behind an impeccable glow.2Dr. Rodney is a fan of this formula, too, lauding the brand’s unique formula that maximizes the stability and efficacy of vitamin C and yields “impressive results.” We agree, seeing a noticeable change in our skin after using this for six weeks—it was not only more illuminated and glowier, but our fine lines and wrinkles appeared less noticeable, too.

If you’re looking for a splurge-worthy pick that’sguaranteed to deliver results and is dermatologist-approved, this is it.

Long-lasting usage
Adds a glow
Evens out hyperpigmentation
Might not work fast enough for some
The secret to this beloved serum is its active ingredient, viniferine,which comes from grapevine sap and, according to the brand, is 62 times more effective than vitamin C when boosting radiance. This recipe alsohydrates without feeling greasy, thanks to the ingredient olive squalane. Lightweight and great for evening skin tone, you can rest assured that its not lacking at all in efficacy.
Who It’s For
For those who want to both target spots and enhance their overall glow, this is an excellent choice.

Contains skin-soothing ingredients
Relies on vitamin C as well as other illuminating actives

There’s vitamin C in this pick—derived from green tangerines, per the name—but there’s also a high concentration of niacinamide (four percent, to be exact). It’s alsonice and hydrating and contains soothing centella asiatica, always a boon if you have sensitive skin.3We noticed that our skin looked healthier, luminous, and generally more even after a few weeks—and saw an improvement in texture after just a few days.

This is a nice pick for anyone with serious spotssince it relies on several different skin-tone-evening ingredients.

Unique, tube-like packaging makes it easy to dispense
Fragrance-free
Not cruelty-free
There’s an impressive 10 percent concentration of pure vitamin C in this formula, making itsuper effective both for illuminating skin as well as delivering overall anti-aging benefits; it helps to smooth out the look of fine lines and wrinkles, too.We really like that it came in a metal tube, making it easy to dispense just the right amount. But that tube has an added benefit; it also keeps that potent vitamin C from being exposed to light or air so that it doesn’t break down. While we didn’t necessarily see instant results, it did definitely leave our skin more luminous and firmer in the long run—so much so that we could even start wearing less makeup.
Who It’s For
This is a great choice for those on a budget, as well as those who havemore mature skin and want a serum that delivers generally good anti-aging benefits.

What to Look For In a Radiance-Boosting Serum
Vitamin C: Rodney says this is one of the best illuminating ingredients out there. It’s both a powerful protective antioxidant but also works to inhibit the production of tyrosinase, an enzyme needed for melanin (aka, pigment production). Find it in many of our winning products, like the L’Oréal Paris Revitalift Vitamin C Serum and Biossance Squalane + Vitamin C Rose Oil.Alpha hydroxy acids: These help to slough off dead, discolored cells, revealing healthy, more even-toned skin underneath, Rodney explains. You can also look for their slightly gentler counterpart, PHAs, which are found in the OLEHENRIKSEN Banana Bright 15% Vitamin C Serum.Kojic acid:
Rodney also likes this natural ingredient, which helps reduce dark spots by slowing down melanin production in target areas.
Always check the label of your products to see what the manufacturer recommends. But depending on the type of illuminating serum you’re using, you can typically use it up to two times per day: in the morning and at night. That said, products that contain actives such as alpha hydroxy acids should typically be used only once per day or less often, as they can potentially over-dry and irritate the skin. If your radiance-boosting serum doesn’t contain any exfoliating or drying ingredients, it’s probably safe to apply twice per day.
Usually, you can. Many radiance-boosting serums work well under makeup. You can use an illuminating serum as a primer, as some may help makeup apply more evenly and look smoother. And it goes without saying, but always apply your makeup after you have completed your entire skincare routine. But you might want to skip using an illuminating serum under makeup if your product contains potentially irritating ingredients that can cause initial redness.
Radiance-boosting serums that don’t contain any exfoliants should be safe for most, if not all, skin types. With illuminating serums that do contain chemical exfoliants, you’ll first want to make sure that those ingredients are a fit for your skin type. All skin types can generally benefit from a radiance-boosting serum, as they’re designed to make skin appear smoother and more glowing. There are many serums that also address signs of aging.
