25 Best Face Serums of 2024, According to Experts and Cosmo Editors

Retinol is one of the best ingredients out there for treating signs of aging (like fine lines and dark spots) but not all retinol formulas created equal. So if you want to incorporate a retinol face serum into your routine, pick up this editor favorite from facialist Shani Darden's skincare line. It combines a stable, encapsulated form of retinol with AHAs to improve skin tone, texture, and elasticity. And unlike many retinol serums I've tested over the years, this isn't the slightest bit drying or irritating.

• Key ingredients: Retinol, AHA, apple fruit extract
• Size: 1 fl oz.
• Usage: Evening

A customer writes: "A must in my nighttime routine! I’ve been using this product for 3 years now and it's never dried out my skin. I was reluctant on retinols because each one I had tried was expensive and would peel my skin like crazy, but this is so gentle."

I've sung the praises of this vitamin C serum countless times, and I'm about to do it again. It's a favorite of Russo's, and contains l-ascorbic acid (one of the most stable, well-studied forms of vitamin C), and vitamin E and ferulic acid, which boosts the efficacy of the vitamin C. And very cool fact: The formula stays active for 72 hours after you dab it on, even after washing your face.

Now in my testing experience, C E Ferulic isn't the best option if your skin is oily and/or acne-prone, but don't worry because Skinceuticals has a slightly different vitamin C serum called Silymarin CF that's specifically formulated to help curb breakouts and give your skin a glow too.

• Key ingredients: L-ascorbic acid, vitamin E, ferulic acid
• Size: 1 fl oz.
• Usage: Morning

One satisfied shopper writes: "This is hands down the best vitamin C serum I've used, and I've tried a range of different brands from The Ordinary to Drunk Elephant," writes a tester. "CE Ferulic is the only product that has made a difference in my hyperpigmentation and dark spots. The texture goes on smoothly and is absorbed by my skin quickly, making it easy to integrate into my routine."

According to Dr. Lolis (and like every beauty editor), this is an excellent quality hyaluronic acid serum, especially for the price. It combines hyaluronic acid (a humectant that draws moisture to the skin for a plump, dewy effect) with vitamin B5 to boost the hydrating effects of the hyaluronic acid, says Dr. Lolis.

• Key ingredients: Hyaluronic acid, vitamin B5
• Size: 1.7 fl oz.
• Usage: Morning and/or evening

An Amazon customer writes: "La Roche-Posay Hyalu B5 Serum for the face is a skincare gem that lives up to its promises. It provides exceptional hydration, is gentle on sensitive skin, and offers some anti-aging benefits. If you're looking to step up your skincare game and achieve a more hydrated, radiant complexion, this serum is definitely worth considering."

SkinMedica's TNS Advanced+ Serum has a cult-like following among dermatologists, aestheticians (it's a favorite of Jarosz's, FYI), and beauty editors alike for it's anti-aging benefits. It uses a blend of growth factors, peptides, green microalgae, and marine extracts to firm, lift, and smooth skin with continued use. Just check out these before and afters for proof. "This serum has a lightweight texture that absorbs well without feeling heavy," adds Jarosz.

• Key ingredients: Growth factor blend, peptides, French flax seed extract, green microalgae extract
• Size: 1 fl oz.

One Amazon shopper writes: "I don’t know what's in this, but it makes my skin look fantastic! Yes, it’s expensive but I actually see a difference which is usually not the case."

The only thing more annoying than breakouts? The stubborn dark marks and scars they leave behind. DW though, this serum from CeraVe is specifically designed to help fade those acne marks and scars without irritating your skin. It uses a gentle form of retinol plus brightening niacinamide and licorice root extract to get the job done.

One Amazon shopper writes: "You only need a tiny bit of this serum. It glides on and rubs in beautifully plus it is unscented. I'm a big fan of Cerave products and this one earns all of its stars."

Please allow me to introduce you to the magic that is T.L.C. Framboos Glycolic Night Serum. The resurfacing serum uses glycolic acid (a dermatologist-loved chemical exfoliator) to smooth fine lines, fade dark spots, reduce congestion, and minimize pore size too.

• Size: 1 fl oz.

A customer review reads: "I originally got a mini sample of this product and I loved it so much that I had to buy the full size. It makes my face so smooth and got rid of all of the bumps on my face."

Another favorite or Jarosz's, this serum contains two stellar hydrators—hyaluronic acid and vitamin B5. "It’s excellent for hydration, as hyaluronic acid helps the skin retain moisture, while vitamin B5 soothes and softens the skin. This combination can leave the skin feeling plump and well-nourished.

It absorbs quickly into the skin without leaving a heavy or sticky feeling, making it suitable for all skin types. including oily and acne-prone skin, adds Jarosz.

• Key ingredients: Hyaluronic acid, vitamin B5
• Size: 1 fl oz.
• Usage: Morning and/or evening

One satisfied customer writes: "I have oily skin and contrary to popular belief (or to my belief rather), oily skin lacks hydration which is why it produces more oil. Anyway, my aesthetician recommended this product to me and it really made a difference on my skin! The product absorbs fast and well into your skin leaving it soft and hydrated. I use it day and night alongside my moisturizer."

My top pick for best dark spot correcting serum, this is a total gem for anyone dealing with sun spots from UV damage or dark marks from old breakouts. I've been using it twice a day for five weeks and not only has it visibly faded the post-inflammatory hyperpigmentation on my chin, but the little sun spots on my cheek bones and around my eyes too.

I've tried multiple other brightening/dark spot treatments and have never seen such a drastic difference this quickly! I've been using this every other night after toning and before moisturizing and it has done wonders for my acne scars and sun spots."

Not all products that go viral on TikTok are worth the hype IMO, but this face serum from Glow Recipe is most definitely deserving of the buzz. It uses niacinamide to brighten your skin tone and fade dark spots with continued use, and thanks to hyaluronic acid and watermelon extract it immediately plumps and hydrates your skin for a dewy, glazed-donut type glow. Most testers use it as a base under makeup, but I love mixing a few drops with my tinted moisturizer or dabbing it over my foundation for a super luminous effect.

A Sephora shopper writes: "This is one of my favorite skincare products. It blends into the skin quickly and gives you a natural glow. Very hydrating, perfect for dry and sensitive skin."

Okay, I know this face serum is ridiculously expensive, but it's my latest skincare obsession so I had to share it with y'all. It's softened the horizontal lines on my forehead, brightened my post-inflammatory acne scars, and even reduced the intensity of the melasma hanging out on my cheeks and jawline thanks to a blend of regenerative stem cells, exosomes, growth factors.

I'm also hooked on the texture—it has a lightweight, watery consistency that easily glides across my skin and the soaks in quickly. I layer it under moisturizer and sunscreen every morning and have never experienced any pilling or patchiness.

Retinol is a fantastic anti-aging ingredient, but it's not well tolerated by sensitive skin types and it can't be used during pregnancy. An alternative ingredient to consider if retinol can't be used in your routine? Bakuchiol. The plant-derived ingredient is found in tons of popular retinol-alternative serums (including this top-seller from Burt's Bees) thanks to its ability to jumpstart collagen and elastin production and boost your skin's cell renewal process.

One shopper says: "I adore this product and I'm not a regular user of Burt's Bees products. This was a surprising find. It feels great on the skin and works well under other products.

Not sure if it will actually tighten my skin but I liked this so much I've ordered a second bottle and told friends about it."
