Want Plump, Hydrated Skin? Choose the Right Type of Hyaluronic Acid

Understanding the Different Types of Hyaluronic Acid in Skincare

We’ve often sung the praises of hyaluronic acid—a true game-changer in the world of skincare. Renowned for its extraordinary ability to hydrate and revitalize the skin, hyaluronic acid (HA) has become a staple in countless beauty routines. Whether you’re a skincare novice or a seasoned enthusiast, chances are you’ve heard of this powerful ingredient. But did you know that there are actually several types of hyaluronic acid used in skincare formulations? That’s right—HA isn’t just one single thing, but a group of molecules with varying structures and purposes.

In this extended post, we’ll take a deep dive into the different types of hyaluronic acid, explore their unique properties, compare how they work, and provide helpful guidance on how to use them in your skincare routine for maximum results.

What is Hyaluronic Acid? A Quick Refresher

Before we get into the types of hyaluronic acid, it’s important to understand what it actually is. Hyaluronic acid is a naturally occurring substance in the human body, found primarily in connective tissues, skin, and eyes. It acts as a humectant, which means it draws moisture from the environment into the skin, helping it retain water and stay hydrated.

In fact, hyaluronic acid is capable of holding up to 1,000 times its weight in water, making it one of the most effective ingredients for skin hydration. As we age, the natural production of HA in our body decreases, which contributes to dryness, loss of elasticity, and the appearance of fine lines and wrinkles. That’s why incorporating it into your skincare routine can offer significant, visible benefits.

How Many Types of Hyaluronic Acid Are There?

Technically, there are three primary forms of hyaluronic acid used in skincare formulations. Each one plays a slightly different role depending on its molecular structure and size. These are:

1. Hydrolyzed Hyaluronic Acid

Hydrolyzed hyaluronic acid is created by breaking down larger HA molecules into smaller fragments. These smaller molecules can penetrate the upper layers of the skin more easily than their full-sized counterparts. However, because they don’t go too deep, their effects tend to be more surface-level.

Best for: Surface hydration and plumping effect. Ideal for people with dry or dull skin looking to restore a smoother texture.

2. Sodium Hyaluronate

Sodium hyaluronate is the salt form of hyaluronic acid and one of the most commonly used ingredients in skincare products. What makes this version stand out is its smaller molecular size, which allows it to penetrate deeper into the skin. It is also more stable and less prone to oxidation than traditional HA.

Another important point is that sodium hyaluronate is water-soluble, which helps it deliver hydration at a deeper level within the skin’s layers. This deeper penetration can lead to more long-term benefits such as improved skin elasticity and reduced appearance of wrinkles.

However, caution is advised when using products that contain a high concentration of sodium hyaluronate (usually more than 4%). In excess, it can actually have the opposite effect by drawing moisture out of the skin, especially in low-humidity environments, leading to dryness rather than hydration.

Best for: Deep hydration, anti-aging concerns, and maintaining skin elasticity. Great for mature or dehydrated skin.

3. Sodium Acetylated Hyaluronate

This lesser-known form of HA is a chemically modified derivative of sodium hyaluronate. By adding acetyl groups, this version becomes even more adhesive to the skin, providing longer-lasting hydration. It also forms a sort of protective film on the skin’s surface that helps lock in moisture.

It may not be as widely known as the other two, but sodium acetylated hyaluronate is becoming more popular due to its enhanced moisture-retention capabilities and longer-lasting results.

Best for: Long-lasting hydration, enhancing skin’s natural barrier, and protecting against moisture loss throughout the day.

Are All Hyaluronic Acids the Same?

Although all forms of hyaluronic acid share similar hydrating properties, they are not created equal. Their key differences lie in:

Molecular weight

Depth of penetration

Duration of effect

Stability in skincare formulas

This is why many high-quality skincare products include a blend of different HA molecules to offer multi-layer hydration. Combining these forms allows the product to deliver moisture both at the surface level and deeper into the dermis, creating a more balanced and effective formulation.

What Is the Best Type of Hyaluronic Acid for Skincare?

The answer to this question depends entirely on your skin type, concerns, and the climate you live in.

Dry or sensitive skin: Look for products that contain sodium acetylated hyaluronate or hydrolyzed HA for soothing and long-lasting surface hydration.

Aging or mature skin: Go for formulations that feature sodium hyaluronate for its ability to penetrate deeper and smooth out fine lines.

Combination or normal skin: A product that contains a blend of HA types is best, offering hydration at multiple levels of the skin.

What’s most important is to pay attention to the concentration and formulation. A well-formulated serum or moisturizer will often combine HA with other hydrating and barrier-supporting ingredients like glycerin, ceramides, or niacinamide.

How Much Hyaluronic Acid Is Effective in Skincare?

It’s a common misconception that more hyaluronic acid equals better results. In reality, there’s a sweet spot for effectiveness.

Most skincare products contain between 0.1% and 2% HA. Although some marketing materials may tout “90% hyaluronic acid,” this is usually misleading and refers to a base that contains HA diluted in water, not the actual concentration of HA.

In fact, high concentrations (especially of sodium hyaluronate) can backfire and cause trans-epidermal water loss, where the ingredient pulls moisture from the skin instead of the air—especially in dry environments.

Ideal concentration: Stick with 1–2%, particularly if you’re new to using HA. This level is effective, non-irritating, and delivers visible hydration benefits without compromising the skin barrier.

When and How Should You Apply Hyaluronic Acid?

For best results, apply hyaluronic acid to damp skin, not dry. This allows the ingredient to draw moisture into the skin more effectively. Follow up immediately with a moisturizer or face oil to lock in that hydration and seal it into the skin.

Ideal steps for using HA in your routine:

Cleanser – Start with a gentle, hydrating cleanser.

Toner or Mist – Lightly spritz your face with water or toner.

Hyaluronic Acid Serum – Apply a few drops while your face is still damp.

Moisturizer – Lock in hydration with a barrier-repairing cream or lotion.

SPF (Morning only) – Always protect your skin with sunscreen.

Does Age Matter When Using Hyaluronic Acid?

Not at all! Hyaluronic acid is one of the most universal and versatile ingredients in skincare and can benefit people of all ages. Whether you’re in your early twenties or well into your sixties, HA has a role to play in maintaining skin health.

Under 25: HA helps maintain moisture and prevent premature signs of aging.

25–40: Boosts hydration, reduces fine lines, and enhances glow.

40 and beyond: Provides deep hydration, softens wrinkles, and supports skin firmness.

When to See a Dermatologist

If you’re using HA-based skincare products consistently and still experiencing dryness or lack of improvement, it may be worth consulting a dermatologist. You may require stronger, prescription-grade treatments or have an underlying condition such as eczema or rosacea.

Also, as with any new product, patch testing is recommended. Apply a small amount behind the ear or on your wrist and monitor for 24 hours before introducing it to your face.

Final Thoughts: Is Hyaluronic Acid Worth the Hype?

Absolutely. Hyaluronic acid, in all its forms, is one of the most effective, versatile, and skin-friendly ingredients available in the beauty world. When used properly, it offers transformative hydration, plumps the skin, reduces signs of aging, and supports the skin barrier.

By understanding the differences between the various forms of HA, you can make smarter choices when selecting your skincare products. Look for multi-molecular formulations, apply it correctly, and always follow up with a moisturizer to lock in the benefits.

DQH Knowledge drop: In your 20s, your skin cell turnover decreases. (Cell turnover is a key component in keeping your skin youthful.) You know what else slows down? Your collagen production. Starting in your 20s, collagen decreases by about 1 percent per year. Should you want to prevent fine lines and wrinkles, start by eliminating behaviors that contribute to premature aging. “If it’s bad for you, it’s bad for your skin,” says dermatologist Michel Somenek. “Cigarette smoking reduces blood flow to the skin and causes premature wrinkling and a dull skin texture. Making the repeated pursed motion to inhale can also cause smoker’s lines. Alcohol and recreational drugs are toxins for the skin that damage its cellular structure and DNA,” Somenek tells us. “The faster you eliminate vices while you are young, the better chance your skin and body have to recuperate.” Also, adopting an anti-aging routine in your 20s is key. After all, the best offense is a good defense. We spoke to Somenek and experts Joshua Ross and Audrey Kunin to find out more. Keep reading for the best anti-aging products for your 20s, according to skincare professionals. Sunscreen “We all know that the sun is the number one cause of skin aging and starting the prevention in your 20s is very important,” Ross says. “The majority of your sun damage won’t start to appear until you’re in your 30s, so don’t wait until you see it surface or you’ll be behind the curve. Stay ahead of it with a good-quality zinc-based sunscreen worn daily.” Farmacy Green Defense Daily Mineral Sunscreen An invisible sunscreen with SPF 30, plus botanical extracts meant to protect skin with tons of antioxidants. Bonus: It’s clean and fine to use under makeup. Bareminerals Complexion Rescue™ Tinted Moisturizer Broad Spectrum SPF 30 Although we recommend you use your SPF and moisturizer separately, we also understand moments when you don’t have time or energy for that extra step. For those times, this bareMinerals moisturizer is a great thing to have on hand. Vitamin C Serum “A great introduction to anti-aging is to start with a vitamin C serum in your morning skincare routine,” Ross says. “It’s a powerful antioxidant that will neutralize free radicals and brighten the skin.” He adds that it’s a great way to counteract the effects of the sun’s harmful rays, which, as previously mentioned, are among the biggest causes of premature aging. Drunk Elephant C-Firma™ Vitamin C Day Serum The Drunk Elephant C-Firma is a lightweight serum that promises to give skin a glow by combining the brightening powers of vitamin C with ferulic acid, l-ascorbic acid, and vitamin E. The included sodium hyaluronate is meant to replace hydration loss, so you shouldn’t have to deal with any irritation. Sunday Riley C.E.O. Rapid Flash Brightening Serum This potent serum is jam-packed with vitamin C (15 percent, to be exact), which means it’s a potential superstar at both brightening skin and dousing it in antioxidants. Peptides Using peptides on your skin has many benefits, says Somenek. “The skin barrier is what defends the body against pollution, UV rays, bacteria, and toxins. It can be damaged by several everyday factors. Using topical peptides aids in building a stronger barrier,” he says. “Peptides comprise elastic fibers, which are a type of protein. These fibers help to make skin appear taut and firm. Peptides can also help repair damaged skin, relieve inflammation, and even out skin tone. Some peptides can kill acne-causing bacteria that is common in 20-somethings.” Kunin agrees, saying, “Peptides are an excellent entry point for supporting collagen.” She recommends looking for face and eye treatments that contain these collagen-boosting powerhouses. Charlotte Tilbury Magic Eye Rescue Cream This Charlotte Tilbury super-emollient eye cream has a base of coconut oil and shea butter (read: it’s incredibly hydrating). Botanicals plus peptides are meant to help reduce dark circles and boost collagen, respectively. This creamy moisturizer serves up potent collagen-boosting peptides and pycnogenol, and antioxidant-rich vitamin C. “Instead of sitting on top of the skin, peptides penetrate the outer layer so they go deep. The ‘signals’ they send tell the cells to produce elastin and collagen, which are needed for youthful-looking skin,” explains Somenek. At-Home Peel Pads Remember that skin cell turnover fiasco we talked about earlier? One way to help support it is by exfoliating. “Exfoliation is important to help keep skin fresh and luminous,” Kunin says. She recommends using at-home peel pads as an easy and effective way to exfoliate. “The goal in your 20s is to fight the slowing pace of cell turnover. It is wise to use products that gently exfoliate, yet still remove oil and other impurities. Products that have Alpha Hydroxy Acids (AHA) or Beta Hydroxy Acids (BHA) are a good choice.” According to Somenek, you should only exfoliate two to three times a week. “People of all ages are guilty of over-exfoliating and that can be too much of a good thing,” he says. Dermadoctor Kakadu C Intensive Vitamin C Peel Pad A few swipes of this Derma Doctor powerful peel pad promise to leave your skin glowing and smooth, thanks to the seven (yes, seven) types of chemical exfoliants, including AHA and BHA. It also contains vitamin C via Kakadu plum extract for added brightening and antioxidant protection. KEY INGREDIENTS Kakadu plum extract is sourced from the Kakadu plum, a fruit grown in northern Australia. It contains vitamin C, which restores the skin’s natural barrier, increases collagen production, and soothes irritation. Dr. Dennis Gross Skincare Alpha Beta® Universal Daily Peel Pads These are the gold standard of peel pads, with a cult following and over 900 five-star reviews on Sephora. They’re easy to use and contain a blend of anti-aging exfoliating acids. Emollient Night Cream “In your 20s, you need to start upping the hydration in your skincare routine. You may have been cautious of over-moisturizing because of acne in your teens, but as you enter your 20s, your skin transitions and becomes drier,” Ross says. “I recommend an emollient night cream added into your evening skincare regimen.” “Twenty-somethings need to make sure that they are not using creams that will clog their pores and cause excess oil production,” says Somenek. Opt for non-comedogenic products. Cerave Skin Renewing Night Cream One great choice is the CeraVe Skin Renewing Night Cream, which is a non-comedogenic night cream that leaves skin soft and glowy. It combines the moisturizing powers of ceramides and hyaluronic acid. RoC Retinol Correxion Max Hydration Creme “The best night cream ingredients contain retinol, benzoyl peroxide, and/or salicylic acid or hyaluronic acid. The goal is to moisturize, yet remove excess oil,” says Somenek. This Roc Retinol Correxion cream fits the bill as it contains both hyaluronic acid and retinol so it promises to moisturize while also being non-comedogenic.
