Here’s What I Found
July 12, 2026
My Clean Beauty Bottom Line
After comparing all three hyaluronic acid serums, one thing became clear to me: they all provide excellent hydration, but they take different approaches to supporting healthy-looking skin.
Each formula earned a high rating using The Clean Beauty Lifestyle Rating System, but the best choice depends on your skin type, your skincare goals, and whether you prioritize simplicity, luxurious hydration, or botanical ingredients.

Lightweight hydration that absorbs quickly without feeling sticky
Antioxidant-rich plant extracts that help support healthy-looking skin
A clean beauty formula centered around thoughtfully selected botanical ingredients
A serum that hydrates while helping soothe and refresh the complexion
One of the strongest botanical ingredient profiles of the three
Skip it if: You have sensitivities to botanical extracts, prefer a minimalist formula, or are looking for the lowest-priced option.
My Final Thoughts
If I had to describe each hydrating serum in one sentence, here's how I'd summarize them:
Honest Beauty is the approachable everyday hydrator, delivering reliable moisture in a simple, fragrance-free formula that fits almost any skincare routine.
OSEA is the luxury option, combining multi-level hydration with premium marine and botanical ingredients for a more elevated skincare experience.
100% PURE is the botanical-focused formula, pairing long-lasting hydration with one of the most impressive blends of antioxidant-rich plant ingredients I reviewed.
The good news is that all three avoid many of the ingredients clean skincare shoppers commonly choose to skip while providing excellent hydration and supporting healthier-looking skin. There isn't a single "best" option—only the one that best fits your skin's needs, your ingredient preferences, and your skincare routine.

What I Like
Ingredient Quality: A Thoughtfully Formulated Hydration Serum
The first thing that caught my attention about Honest Beauty Hydrogel Deep Hydration Serum was how thoughtfully the formula is put together.
It leaves out many of the ingredients that clean skincare shoppers commonly choose to avoid, including:
No parabens
No phthalates
No sulfates (SLS/SLES)
No mineral oil
No synthetic fragrance
The formula is also vegan and cruelty-free, making it another excellent option for anyone looking to build a cleaner skincare routine. After comparing several hydrating serums side by side, Honest Beauty stood out for combining multiple forms of hyaluronic acid with skin-conditioning ingredients while avoiding many of the ingredients clean beauty shoppers commonly choose to skip.
Skin-Supporting Ingredients
One thing I always look for in a hydration serum is whether the formula supports the skin beyond simply adding moisture.
Honest Beauty includes several ingredients that help attract and retain hydration while supporting a healthy skin barrier, including:
Three forms of hyaluronic acid to hydrate multiple layers of the skin.
Amino acids and sodium PCA to help attract and retain moisture.
Kiwi seed oil, rich in essential fatty acids that help support the skin's moisture barrier.
Rambutan extract to provide additional hydration and help keep skin looking plump.
I appreciate formulas that combine several moisture-supporting ingredients instead of relying on hyaluronic acid alone.
Fragrance Transparency: Complete Ingredient Disclosure
Synthetic fragrance is one of the first ingredients I evaluate because it's a common source of irritation for many people.
Honest Beauty leaves out added synthetic fragrance entirely and fully discloses its ingredient list. I appreciate brands that clearly disclose their ingredients, allowing consumers to make informed decisions based on their own skincare preferences.
Thoughtfully Selected Botanical Ingredients
Although Honest Beauty doesn't heavily emphasize certified organic ingredients, it incorporates naturally derived botanical ingredients that complement the formula's hydration-focused approach.
While it doesn't rely on organic ingredients to the same extent as some other brands I reviewed, I still appreciate the thoughtful ingredient selection and believe the formula earns a solid three-star organic ingredients rating.
More Than Just a Hydration Serum
One feature I really appreciate is that this serum is designed to do more than simply moisturize.
In addition to delivering lasting hydration, it's formulated to help improve skin softness, smoothness, and the appearance of dehydration lines while supporting an overall healthier-looking complexion.
Gentle Enough for Sensitive Skin
One thing that stood out to me while comparing this serum with others is how simple and gentle the formula feels.
Rather than relying on stronger active ingredients, Honest Beauty focuses on hydration and skin comfort, making it an excellent option for many people with sensitive or easily irritated skin.
Lightweight and Easy to Layer
The lightweight hydrogel texture absorbs quickly without leaving behind a sticky or greasy residue.
It layers easily underneath moisturizer, sunscreen, and makeup, making it simple to incorporate into both morning and evening skincare routines.
Helps Skin Look Smoother and Plumper
By increasing moisture levels within the skin, this serum helps soften the appearance of dehydration lines while leaving the complexion looking smoother, fresher, and more hydrated.
Excellent Value
Another thing that impressed me is the overall value.
Compared with many prestige hydrating serums, Honest Beauty delivers a thoughtfully formulated product at a much more approachable price point, making it an excellent introduction to clean hydration-focused skincare.
Things to Consider
Botanical Ingredients Aren't Perfect for Everyone
Like many clean skincare brands, Honest Beauty includes several plant-derived ingredients throughout the formula.
Although these ingredients provide benefits for many people, natural ingredients can still trigger irritation or allergic reactions in some individuals. Patch testing is always a good idea if you have known sensitivities.
Hydration Is the Primary Focus
This serum is designed primarily to improve hydration.
If your biggest concerns are hyperpigmentation, deeper wrinkles, or significant loss of firmness, you'll likely want to pair it with other targeted skincare products rather than relying on this serum alone.
Results Are Subtle and Build Over Time
Hyaluronic acid provides immediate hydration, but the most noticeable improvements are smoother, softer, healthier-looking skin rather than dramatic long-term changes.
Very Dry Skin May Need Additional Moisture
Although the serum delivers excellent hydration, people with very dry skin may still benefit from following it with a richer moisturizer to help lock in moisture.
Proper Application Matters
Like most hyaluronic acid serums, this formula performs best when applied to slightly damp skin and followed with a moisturizer to help seal in hydration.
Simpler Than Some Prestige Formulas
Compared with some higher-end hydrating serums that include peptides, ceramides, or additional anti-aging ingredients, Honest Beauty keeps the focus primarily on hydration.
Whether that's a drawback depends on what you're hoping your serum will accomplish.
It Isn't Intended to Replace an Anti-Aging Serum
While hydrated skin naturally appears smoother and healthier, this formula isn't designed to replace products formulated specifically for collagen support, firmness, or deeper wrinkles.
My Overall Thoughts
After comparing several clean hydrating serums, Honest Beauty Hydrogel Deep Hydration Serum stands out as one of the most approachable options I've reviewed.
What impressed me most is how successfully it combines thoughtful ingredient selection, complete fragrance transparency, effective hydration, and comfortable everyday wear into one well-balanced formula.
If you're looking for a clean hydrating serum that delivers lasting moisture, layers beautifully into almost any skincare routine, and helps leave your skin looking smoother, plumper, and healthier, I think Honest Beauty Hydrogel Deep Hydration Serum is an excellent everyday choice.
OSEA Hyaluronic Sea Serum
OSEA has built its reputation around luxurious, marine-inspired skincare, and the Hyaluronic Sea Serum reflects that philosophy with a formula designed to deeply hydrate while supporting a healthy-looking skin barrier.
After reviewing the formula and comparing it with other clean hydrating serums, I found it offers an excellent balance of thoughtfully selected ingredients, long-lasting hydration, and premium performance. While no hydrating serum is perfect for everyone, OSEA Hyaluronic Sea Serum is one of the highest-rated serums I've reviewed.

Skin-Supporting Ingredients
One thing I always look for in a hydration serum is whether the formula supports the skin beyond simply adding moisture.
OSEA includes several ingredients that help hydrate, soothe, and strengthen the skin, including:
Multi-molecular hyaluronic acid to attract and retain moisture at multiple levels of the skin.
Organic seaweed extract, naturally rich in minerals, amino acids, and antioxidants that help nourish and soothe the skin.
Provitamin B5 (panthenol) to help support the skin barrier and improve moisture retention.
Snow mushroom extract, a natural humectant that helps draw water into the skin for a plumper-looking complexion.

Rather than relying on hyaluronic acid alone, OSEA combines several complementary ingredients that work together to support healthy, hydrated skin.
Fragrance Transparency: Complete Ingredient Disclosure
Synthetic fragrance is one of the first ingredients I evaluate because it's a common source of irritation for many people.
OSEA leaves out added synthetic fragrance entirely and fully discloses its ingredient list. I appreciate brands that clearly list their ingredients rather than relying on vague fragrance blends, allowing consumers to better understand what they're putting on their skin.
Meaningful Use of Organic and Marine Ingredients
Another aspect I appreciate is OSEA's use of high-quality botanical and marine-derived ingredients throughout the formula.
The serum incorporates organic seaweed and aloe vera alongside other naturally derived ingredients that align with the brand's clean skincare philosophy. While the formula isn't entirely organic, OSEA makes meaningful use of organic ingredients while balancing them with performance-focused ingredients, earning a strong four-star rating for organic ingredients.
More Than Just a Hydration Serum
One feature I really appreciate is that this serum does more than simply hydrate.
In addition to helping replenish moisture, it's formulated to soothe the skin, strengthen the moisture barrier, provide antioxidant support, and improve the appearance of dehydration throughout the day.
Excellent for Dry or Dehydrated Skin
If your skin often feels tight, dull, or dehydrated, I think this formula has a lot to offer.
The combination of multiple forms of hyaluronic acid, marine botanicals, snow mushroom, and aloe helps deliver lasting hydration without leaving the skin feeling heavy or greasy.
Lightweight and Layers Beautifully
Despite its deeply hydrating formula, the serum has a lightweight texture that absorbs quickly.
It layers beautifully underneath moisturizer, sunscreen, and makeup, making it easy to incorporate into both morning and evening skincare routines.
Helps Skin Look Plumper and Healthier
Like many well-formulated hyaluronic acid serums, OSEA helps soften the appearance of dehydration lines by increasing moisture levels within the skin.
The result is skin that looks smoother, plumper, and noticeably healthier.
Antioxidant Support From Marine Botanicals
One feature that separates OSEA from many other hydrating serums is its emphasis on marine-derived ingredients.
Seaweed and other botanical extracts provide naturally occurring antioxidants that help defend the skin against everyday environmental stressors while supporting healthier-looking skin over time.
Things to Consider
Botanical and Marine Ingredients Aren't Perfect for Everyone
Like many clean skincare brands, OSEA includes a variety of botanical and marine-derived ingredients throughout the formula.
Although these ingredients provide benefits for many people, they can still trigger irritation or allergic reactions in some individuals. Patch testing is always a good idea if you have known sensitivities.
It's Definitely a Premium Serum
There's no question that OSEA sits firmly in the prestige skincare category.
You're paying for thoughtfully selected ingredients, premium formulation, and a luxurious skincare experience, but it is a significant investment compared with many other hydrating serums.
Hydration Is the Primary Focus
This serum excels at hydration, soothing, and supporting a healthy skin barrier.
If your primary concerns are pigmentation, acne, or deeper wrinkles, you'll likely want to pair it with additional treatment serums.
Results Are Hydration-Based
One of the biggest strengths of hyaluronic acid is how quickly it improves the skin's appearance through hydration.
You'll likely notice softer, smoother, and plumper-looking skin fairly quickly, while longer-term improvements depend on the rest of your skincare routine.
Very Dry Skin May Still Need a Rich Moisturizer
Although this serum provides excellent hydration, people with extremely dry skin will usually achieve the best results by following it with a richer moisturizer to help lock in moisture.
Proper Application Makes a Difference
Like most hyaluronic acid serums, OSEA performs best when applied to slightly damp skin and followed with a moisturizer to help seal in hydration.
It Isn't Intended to Replace a Complete Anti-Aging Routine
While hydrated skin naturally appears smoother and healthier, this serum isn't designed to replace products formulated specifically for collagen support, deeper wrinkles, or significant discoloration.
My Overall Thoughts
After comparing several clean hydrating serums, OSEA Hyaluronic Sea Serum stands out as one of the most luxurious and well-rounded options I've reviewed.
What impressed me most is how successfully it combines exceptional ingredient quality, complete fragrance transparency, meaningful use of organic and marine-derived ingredients, and long-lasting hydration into one thoughtfully formulated product.
If you're looking for a premium clean hydrating serum that helps replenish moisture, strengthen the skin barrier, and leave your complexion looking smoother, healthier, and more refreshed, I think OSEA Hyaluronic Sea Serum is one of the best options currently available.

100% PURE is known for creating plant-based skincare with naturally derived ingredients, and the Rose Water Hyaluronic Acid Serum reflects that philosophy with a formula that combines hydration, soothing botanicals, and antioxidant support.
After reviewing the formula and comparing it with other clean hydrating serums, I found it offers an excellent balance of thoughtfully selected ingredients, lasting hydration, and botanical skin support. While no hydrating serum is perfect for everyone, this is one of the highest-rated serums I've reviewed.

Rose hydrosol to refresh the skin and support a healthy-looking complexion.
Hyaluronic acid to attract and retain moisture for smoother, plumper-looking skin.

You'll likely notice softer, smoother, and more hydrated skin early on, while improvements in overall skin appearance continue with consistent use.
