Wherever you see hyaluronic acid, moisture is one thing that cannot be overlooked. It is an active ingredient in moisturizers, serums, eye creams, and even hair care products. This article looks at hyaluronic acid in a serum and what it does for your beauty routine.

In simple terms, hyaluronic acid serum boosts hydration levels in your skin and hair. More so, hydration guarantees maximum protection from new and progressive beauty-related concerns.

This acid is also naturally present in the body and so it is very safe for health and cosmetic purposes.

Hyaluronic acid has become a common ingredient in almost every skincare routine. This is because of its mildness, unlike other acids which are rather drying and exfoliating.

What Does Hydrating Hyaluronic Acid Serum Do?

The hydrating hyaluronic acid serum is a dermatologist-developed serum that intensely hydrates the skin. Hyaluronic acid, a humectant, attracts moisture to your skin and holds it down for up to 24 hours. It plumps skin cells and keeps your skin moisturized.

This serum effectively makes up for depleted hyaluronic acid levels that come with aging. It is packed with ceramides which help to strengthen skin barrier function.

Moreover, it can help restore a compromised barrier, which makes it good for people with sensitive skin.

In addition to ceramides, the serum also contains vitamin B5 which helps to soothe the skin. You may wonder if you can use it for oily and acne-prone skin, and the answer is yes. Hydrating hyaluronic acid is a non-comedogenic serum that is also fragrance-free.

What Does Hyaluronic Acid Serum Do for Your Face?

A hyaluronic acid serum is one of the topical ways to supply facial skin with hyaluronic acid. As you age, your skin naturally loses hyaluronic acid, which is necessary for collagen synthesis and smooth, youthful skin.

Hyaluronic acid serum on your face increases moisture levels of facial skin and helps to alleviate dryness which can be the onset of wrinkles and fine lines. Moreover, this serum uses moisture to improve the texture of your skin.

With consistent use, it improves the appearance of rough skin and enhances elasticity. Furthermore, it increases the resilience of the skin’s barrier and fortifies your skin against environmental pollutants.

A proper functioning barrier keeps in moisture and protects your skin from toxins. Other benefits of using hyaluronic acid serums for your face include improved skin tone (it helps with hyperpigmentation too), firmer skin, and skin cell regeneration.

What Does Hyaluronic Acid Serum Do for Acne?

Yes, hyaluronic acid is great for dry skin but it doesn’t stop there. It is also great for oily and acne-prone skin. Although an acid, hyaluronic acid doesn’t exfoliate the skin and unclog your pores. It uses moisture to prevent acne. How does this work?

Using hyaluronic acid serums prevents your skin from getting overly dry and overcompensates with excess production of sebum. This way, it keeps pores from getting clogged, thereby preventing the breakout of acne.

In addition, it is very soothing and this helps to reduce the breakout of inflamed acne. This serum doesn’t fill in acne scars but it does help reduce the appearance of the scars and reduce skin redness.

Research shows that applying hyaluronic acid serums to acne scars can reduce scarring and give you clear, radiant skin.

Acne-prone skin is characterized by a compromised skin barrier. Hyaluronic acid replenishes moisture and restores the skin barrier. Therefore, it protects your skin from environmental pollutants that can cause acne.

What Does Hyaluronic Acid Serum Do for Wrinkles?

Hyaluronic acid serum moisturizes the skin, increases hydration levels, and improves the appearance of fine lines and wrinkles.

These phenomena set in as you age and natural hyaluronic acid is lost. It also comes with a loss of collagen and skin elasticity.

When your skin is dehydrated, the skin barrier cannot effectively defend your skin from free radicals that cause premature aging. The serum restores skin barrier function and protects your skin from these irritants.

Additionally, hyaluronic acid can help stimulate your skin to produce collagen which will help restore skin elasticity. As a powerful humectant, it retains moisture in your skin and keeps it looking plump and youthful.

What Do Hyaluronic Acid Serums Do for Undereye?

Hyaluronic acid is naturally present around the eyes, therefore, it is good for under-eye area problems like dark circles. Under-eye problems are a result of many issues like dehydration, aging genetics, lack of sleep, and tiredness.

The skin around the eyes is prone to dryness and the development of wrinkles. Applying hyaluronic acid serum to this area can help to pull moisture into the skin and reduce the appearance of wrinkles.

Also, using the serum ahead of time can prevent the development of wrinkles. In addition, it is very soothing on the skin and can help depuff eye bags and give you brighter eyes. It restores skin glow and helps to smoothen out roughened skin.

What Does Hyaluronic Acid Serum Do for Hair?

Hyaluronic acid serums also benefit the hair. Its hydrating properties help to hydrate your hair strands and scalp. It makes your hair more manageable. People with type 3 and 4 hair are very familiar with the battle against frizz and dryness.

Adding hyaluronic acid serums to your hair care regimen will be a hair saver. By boosting hydration levels, the serum protects your hair from getting dry, brittle, and eventually breaking. It also prevents frizz and split ends from ruining your curls.

Additionally, the serum may help stimulate hair growth by nourishing and hydrating your scalp. Just like every hair serum, it coats your strands, increases hair volume, and gives your hair a reflective look.

Does Hyaluronic Acid Cause Weight Gain?

No, it doesn’t. Topical or oral hyaluronic acid cannot cause weight gain because it does not contain calories. The moisture it retains does not bloat you up. It absorbs into the skin, plumps skin cells, and reflects on the surface of your skin.

Hyaluronic acid leaves the skin hydrated and increases moisture retention capacity. None of this in any way affects lipid concentration in the body.

Potential Side Effects of Using Hyaluronic Acid Serums

Hyaluronic acid serums rarely show any side effects on the skin and hair. However, there could be exceptions when you’re a first-timer or when you use the serum incorrectly.

On a first-time application, you may experience a burning sensation, skin redness, and irritation. This should not be a cause for worry; these signs will go away in a matter of days when your skin gets familiar with the serum.

Naturally, in a humid environment, hyaluronic acid will pull moisture from the atmosphere into your skin. In dry climate conditions, the reverse happens if you do not use a moisturizer over hyaluronic acid serum. It pulls moisture from the deep layers of your skin and leaves it drier.

The good news is, these side effects are easily reversible and avoidable. Always run a patch test with a new product to check for incompatibility issues. Also, always use moisturizer after applying hyaluronic acid serum.


How often should you use a hyaluronic acid serum?

Use hyaluronic acid serum two times, every day to keep your skin hydrated and protected. Always apply the serum to pre-cleansed, damp skin and use a moisturizer over it. Applying too much hyaluronic acid can leave your skin more dehydrated than it found it.

Is hyaluronic acid serum good for curls?

Yes, it is. Hyaluronic acid keeps curls hydrated and enhances the bounce and movement of the curls. Also, while the serum protects curls from frizz and breakage, it aids in styling and aids detangling.

Does hyaluronic acid lighten skin?

Hyaluronic acid serums do not have skin-lightening properties but can help brighten your complexion. These serums add moisture to your skin and reduce the appearance of dark spots and hyperpigmentation that distort your complexion.


Hyaluronic acid is a powerful hydrator that provides your skin and hair with loads of benefits. These benefits, however, come with correct usage. It creates a protective seal over your skin to prevent moisture loss and consequent dehydration.

Hyaluronic acid serums make a great addition to any skincare routine and hair care regimen. You’ll agree that the absence of moisture is the major cause of many skin-related conditions. If you get it right with moisture, you’re looking at better skin days.

Most importantly, you can never be too careful. If you have reservations about hyaluronic acid serums, you should discuss this with your doctor.
