Â
A few months ago, a patient walked into my clinic holding two expensive skincare products. She looked genuinely confused.
“Doctor, both of these say they contain hyaluronic acid, but my skin still feels dry by evening. Am I doing something wrong?”
It’s a question I hear surprisingly often.
People assume that if a product contains hyaluronic acid, it’s automatically going to solve every hydration problem. The reality is a little more nuanced. Hyaluronic acid is one of my favourite skincare ingredients because it’s gentle, versatile, and suitable for most people—but like any skincare ingredient, it works best when it’s used correctly and paired with the right routine.
If you’ve been curious about the benefits of hyaluronic acid for skin, here’s what I usually explain to my patients.
What Is Hyaluronic Acid?
Despite its name, hyaluronic acid isn’t the kind of acid that exfoliates your skin.
Think of it as a moisture magnet.
Our skin naturally contains hyaluronic acid, where its job is to attract and hold water. This helps keep skin soft, flexible, and comfortable. As we grow older—and thanks to factors like sun exposure, pollution, and dry weather—the amount of natural hyaluronic acid in our skin gradually decreases.
That’s one reason skin can begin to feel drier and lose some of its natural bounce.
Topical hyaluronic acid serum products don’t replace what’s been lost forever, but they can help improve hydration and support healthier-looking skin when used consistently.
Why Dermatologists Recommend Hyaluronic Acid
There are very few skincare ingredients that suit such a wide range of people.
In my clinic, I recommend hyaluronic acid to teenagers dealing with dehydrated oily skin, adults noticing early signs of ageing, and even patients whose skin has become sensitive after certain treatments.
Why?
Because hydrated skin generally functions better.
Hyaluronic Acid Helps Your Skin Stay Hydrated
Hydration is probably the biggest reason people reach for hyaluronic acid.
It works by attracting water to the outer layers of the skin, helping it feel smoother and more comfortable.
If your skin feels tight after washing your face but becomes oily a few hours later, dehydration—not dryness—could be part of the problem.
Adding HA for hydration often helps restore balance without making the skin feel greasy.
It Can Make Fine Lines Look Softer
One thing I always tell patients is that hyaluronic acid isn’t a wrinkle remover.
It doesn’t erase lines.
What it often does is improve hydration enough that fine, dehydration-related lines appear less noticeable. Skin tends to look fresher, smoother, and a little more plump simply because it contains more water.
That’s a very different claim from saying it reverses ageing.
It Supports the Skin Barrier
Your skin barrier is like a protective shield.
When it’s healthy, it helps keep moisture in and environmental irritants out.
When it’s damaged, skin may sting, become flaky, or feel unusually sensitive.
While hyaluronic acid isn’t a barrier-repair ingredient on its own, well-hydrated skin is generally better able to maintain a healthy barrier. That’s why you’ll often see it paired with ceramides, glycerin, or panthenol in moisturisers and serums.
Is Hyaluronic Acid Suitable for Every Skin Type?
In most cases, yes.
That’s one reason it’s become such a popular ingredient.
Oily Skin
Many people with oily skin avoid hydrating products because they worry about looking shinier.
Ironically, dehydrated oily skin can sometimes produce even more oil.
A lightweight hyaluronic acid serum gives the skin hydration without leaving a heavy finish.
Dry Skin
Dry skin usually benefits from combining hyaluronic acid with a richer moisturiser.
I often explain it this way: hyaluronic acid brings water into the skin, while a moisturiser helps keep that water from escaping.
Using only one of the two may not give the result you’re expecting.
Combination Skin
Combination skin often responds well to hyaluronic acid because it hydrates dry areas without making the oily parts of the face feel overloaded.
Sensitive Skin
Most people with sensitive skin tolerate hyaluronic acid well.
Still, I always recommend introducing one new skincare product at a time. If irritation develops, it’s much easier to identify the cause.
Does More Hyaluronic Acid Mean Better Results?
Not necessarily.
This is probably one of the biggest misconceptions I come across.
People often assume that a serum containing several types of hyaluronic acid or a very high concentration must work better.
That’s not how skincare works.
The overall formulation matters far more than a single ingredient.
A well-formulated serum containing hyaluronic acid, glycerin, and skin-soothing ingredients may perform better than a product focused only on increasing the amount of hyaluronic acid.
What About Different Molecular Weights?
You may have noticed terms like “low molecular weight” or “multi-molecular hyaluronic acid.”
These descriptions refer to the size of the hyaluronic acid molecules.
Larger molecules tend to sit closer to the skin’s surface, helping improve hydration in the outer layers.
Smaller molecules are designed to penetrate a little deeper into the upper layers of the skin.
Neither is universally better.
Many modern formulations combine different molecular weights to provide hydration at multiple levels.
How to Use Hyaluronic Acid Correctly
One small habit can make a surprising difference.
Apply your hyaluronic acid serum to slightly damp skin rather than completely dry skin.
This gives the ingredient moisture to work with before you apply your moisturiser.
A simple routine usually looks like this:
- Gentle cleanser
- Hyaluronic acid serum
- Moisturiser
- Sunscreen during the daytime
At night, you can follow the serum with your regular moisturiser or treatment products.
Can You Use Hyaluronic Acid with Other Skincare Ingredients?
Yes, and that’s another reason dermatologists like it.
Hyaluronic acid works well alongside many common skincare ingredients.
It can be paired with:
- Vitamin C
- Niacinamide
- Ceramides
- Peptides
- Retinoids
- Most moisturisers
In fact, patients using retinoids often find that adding hyaluronic acid helps improve comfort by reducing the feeling of dryness that sometimes occurs during treatment.
A Few Mistakes I See Quite Often
One mistake is relying on a hyaluronic acid serum alone without using a moisturiser afterward.
Another is applying it several times a day hoping for faster results.
Skincare doesn’t usually work that way.
Consistency matters far more than quantity.
And remember, hydrated skin still needs sunscreen every morning.
When Should You See a Dermatologist?
If your skin remains persistently dry, itchy, inflamed, or painful despite following a gentle skincare routine, it’s worth seeking professional advice.
Conditions such as eczema, rosacea, allergic reactions, or certain forms of dermatitis require more than a hydrating serum.
In my clinic, I often meet patients who’ve spent months trying different products when the underlying issue actually needed a proper diagnosis.
My Advice to Patients
Hyaluronic acid has earned its place in modern skincare for a reason.
It’s gentle, easy to incorporate into most routines, and suitable for almost every skin type. Used correctly, it can help your skin feel more comfortable, better hydrated, and healthier over time.
If you’re unsure which formulation suits your skin—or if your skin isn’t responding the way you’d hoped—don’t keep guessing. A personalised consultation often saves far more time and money than constantly switching products.
Frequently Asked Questions
Can I use hyaluronic acid every day?
Yes. Most people can use a hyaluronic acid serum once or twice daily as part of their regular skincare routine.
Should I apply hyaluronic acid before or after moisturizer?
Apply hyaluronic acid after cleansing and before your moisturizer. This helps attract moisture, while the moisturizer helps seal it into the skin.
Is hyaluronic acid good for oily skin?
Yes. Hyaluronic acid provides lightweight hydration without making the skin feel greasy, making it suitable for oily and combination skin.
Can I use hyaluronic acid with retinol or Vitamin C?
Yes. Hyaluronic acid pairs well with both ingredients and may help reduce the feeling of dryness that can occur with stronger active ingredients.
