If you've been scrolling through skincare TikTok or browsing the aisles at Sephora, you've probably seen countless hyaluronic acid serums promising plump, hydrated, glowing skin. But before you drop $40+ on another bottle, let me share what I discovered when I dug into the actual research behind these products.
What I Originally Set Out to Do
I was planning to create a comprehensive review of the top five to seven hyaluronic acid serums on the market. I had my list ready, comparing prices, ingredient lists, textures, and all the marketing claims. But as I dove deeper into the actual scientific studies and measured outcomes, something became clear: most of these serums probably aren't going to benefit you the way you think they will.
After analyzing the hype versus the actual legitimacy, I realized this deserved a different conversation entirely.
What Is Hyaluronic Acid, Really?
Hyaluronic acid (often abbreviated as HA in the skincare world) is actually a naturally occurring substance in your body. It's found in your skin, joints, and even your eyes. Think of it as your skin's natural sponge—it has an incredible ability to absorb and hold moisture.
As a humectant, hyaluronic acid pulls in water to keep your skin looking plump and hydrated. Your body already produces it, which is why it's such a popular ingredient in skincare products. But here's where things get interesting—and where the marketing often misleads consumers.
The Hidden Problem with Hyaluronic Acid Serums
Here's what most people miss, and what the beauty industry doesn't always make clear: hyaluronic acid doesn't actually add moisture to your skin.
Yes, you read that right. If you apply HA to dry skin without the right conditions or supporting ingredients, it can actually pull hydration OUT of your skin rather than bringing moisture in. It can backfire and make your skin more dry.
How Does This Happen?
Hyaluronic acid attracts moisture from wherever it can find it. In a humid environment, it pulls moisture from the air into your skin—perfect! But if the air around you is too dry (think indoor heating, air conditioning, or desert climates), it will pull moisture from the deeper layers of your skin instead.
Context matters:
- Humid weather? Hyaluronic acid works great.
- Indoors with AC or heating? You could actually be drying your skin out and making things worse.
-
Living in Arizona, Nevada, or Utah? That low moisture environment isn't doing your HA serum any favors.
Why Moisturizers Beat Serums (Most of the Time)
This is where the conversation shifts from serums to moisturizers. A well-formulated moisturizer doesn't just contain hyaluronic acid—it also includes emollients and occlusives that work synergistically with HA.
Ingredients like:
- Squalane
- Peptides
- Natural oils
- Niacinamide
- Vitamin B5
These ingredients lock in the moisture that hyaluronic acid attracts and trap water in your skin, keeping it soft, balanced, and healthy.
The Reality Check
Most of you are already getting plenty of hyaluronic acid in your moisturizers. You don't need another $40 serum just to feel like your routine is complete—especially if you're already using something that seals in hydration effectively.
If your moisturizer uses emollients like squalane and peptides to lock it in, you're probably wasting your money on a separate HA serum.
My Honest Recommendation
I'm a big fan of the e.l.f. Holy Hydration Face Cream. Before you think I'm sponsored—I'm not. I'm not a spokesperson or sales rep for e.l.f. I just look for the best products that have the best combinations of formulas and deliver real value.
This moisturizer does a lot of heavy lifting with:
- Hyaluronic acid
- Niacinamide
- Vitamin B5
- Squalane
- Peptides to help lock in moisture
You're getting the extra HA benefits without buying a serum that could actually backfire on you. It's a killer deal for the value, and if you watched my moisturizer breakdown video, you already know why I recommend it.
When Might You Actually Need an HA Serum?
I'm not saying hyaluronic acid serums are completely useless for everyone. There are specific situations where they can be beneficial:
- Your skin is flaking or severely dry from active ingredients like glycolic acid or retinoids
- You need an extra layer of hydration to buffer irritation from other products
- You live in a consistently humid climate where the air moisture will support the HA function
But here's the truth: 90% of people using a solid moisturizer will have their hydration needs covered already.
Where You Should Actually Spend Your Skincare Budget
Instead of spending money on a fancy HA serum that's probably going to backfire for most of you, put that budget toward products with proven efficacy:
1. Vitamin C Serums
These are powerful antioxidants that brighten skin, even out tone, and protect against environmental damage. We've done extensive reviews of vitamin C serums and the science backs up their effectiveness.
2. Nighttime Retinoids
Another very powerful, effective mechanism for skincare. Retinoids are the gold standard for anti-aging and addressing multiple skin concerns.
3. Quality Sunscreen
This can help reduce UV damage and significantly impact the overall timeline of your skin aging. Sun protection is non-negotiable if you care about your skin's health and appearance.
The Bottom Line: Skip the Hype, Follow the Science
So no, hyaluronic acid itself isn't necessarily a scam. But buying standalone hyaluronic acid serums when you're already using a solid moisturizer with HA in a well-formulated blend? That kind of is a scam.
If you're already using a moisturizer with hyaluronic acid and the right emollients, you're set. Save your budget for the heavy hitters that will actually make a visible difference in your skin.
The skincare industry thrives on making you feel like your routine is incomplete. Don't fall for it. Look at what you're already using, understand how the ingredients work together, and make informed decisions based on science, not marketing hype.
