Best hydrating face serums (2026) by skin type
Eight hydrating face serums matched to dry, oily but dehydrated, and sensitive skin, plus dryness that settles into fine lines, with the humectants on each INCI and how to layer them.
By the Lipid Language editorial team
Key takeaways
Which hydrating face serum is best comes down to your skin type. Dry skin does well with humectants plus a few lipids. Oily but dehydrated skin suits a light, water-based serum. Sensitive skin needs a short, fragrance-free list.
Our top pick for most people is Vichy Minéral 89, a fragrance-free gel with Hyaluronic Acid that Vichy says is tested on sensitive skin.
U Beauty’s the Resurfacing Compound ranks #3, for dry-feeling skin that also wants exfoliation: it carries Glycerin and two Hyaluronic Acid forms alongside three acids and a Retinol Ester.
Apply a hydrating serum to damp skin, then seal it with a moisturizer. Humectants attract water, and the moisturizer helps hold it there.
A hydrating serum is the step that’s easiest to get right and easiest to overthink. Almost every one is built on the same idea: humectants, such as Hyaluronic Acid and Glycerin, which pull water into the top layers of skin. Where they differ is in what comes with them, and that’s what makes one serum right for dry skin and another better for skin that’s oily but still feels tight.
So we’ve organized this list by skin type, two picks each, plus a short section on how to use a hydrating serum so it actually feels hydrating.
What makes a face serum hydrating
The workhorse ingredients are humectants. A 2020 review of moisturizers (PMC7473959) describes humectants, from Glycerin to the skin’s own natural moisturizing factor (NMF) components, as hydrating by attracting and binding water. The same review explains that occlusives work differently, by reducing water loss from the skin. A serum is usually the humectant step. The cream that follows is usually where the occlusives come in.
Hyaluronic Acid is the humectant most people know. *Dermatologic Therapy* published a 2022 review (PMC10078143) noting it can hold up to 1,000 times its own volume in water. Its high-molecular-weight forms “primarily stay on the skin’s surface, forming a thin protective hydration layer,” the review says, and low-molecular-weight forms can go deeper. Several serums on this list use more than one form.
Order matters too. Cleveland Clinic’s guide to skin care product order says to go from lightest to heaviest, and suggests using one serum at a time. The AAD’s dry skin tips add the timing: apply moisturizing products while your skin is still damp.
A quick guide by skin type:
Dry skin: humectants plus Ceramides or other lipids, then a cream on top.
Oily but dehydrated skin: a light, water-based serum with humectants, and a lighter moisturizer.
Sensitive skin: a short, fragrance-free ingredient list. Patch test first.
Dryness that settles into fine lines: a humectant serum, or a lipid-rich serum, under a richer cream.

1. Vichy Minéral 89 Hydrating & Plumping Daily Booster: best overall, and best for sensitive skin
Vichy’s water-based gel is the hydrating serum we’d suggest to most people, because it’s fragrance-free, simple to layer, and comes in three sizes. It’s powered, in Vichy’s words, by “the Moisture Acid Twins,” Hyaluronic Acid and Polyglutamic Acid, with Vichy Volcanic Water as the base.
Key features:
Two humectants: Hyaluronic Acid and Polyglutamic Acid.
Vichy calls it fragrance-free and says it’s tested on sensitive skin.
What Vichy reports: in a self-assessment, 93% of 53 subjects said they felt hydration after applying it.
Best for: most skin types, including sensitive skin, as a daily first layer.
Tradeoff: Vichy says slight tackiness is common until you seal it with moisturizer. The price wasn’t shown when we checked, so it varies by retailer.
Price: varies by retailer; sizes 30, 50, and 75 ml.
2. Paula’s Choice Hyaluronic Acid Booster: best for dry skin
Dry skin tends to want lipids with its humectants, and this booster puts both near the top. The INCI reads Water, Glycerin, Sodium Hyaluronate, Hyaluronic Acid, then Ceramide NP, Ceramide AP, and Ceramide EOP, with Cholesterol and Panthenol further down. There’s no fragrance on the list.
Key features:
Two Hyaluronic Acid forms and three Ceramides, all in the top seven.
Flexible use: Paula’s Choice says to “Use alone or add to your moisturizer or serum.”
Can go under the eyes, avoiding the eye itself, per Paula’s Choice.
Best for: dry skin, morning and night, especially mixed into a cream on flaky days.
Tradeoff: at 0.5 fl oz for $39, it’s a small bottle for daily use on face and neck.
Price: $39 for 0.5 fl oz.
3. U Beauty the Resurfacing Compound: best for dry-feeling skin that also wants exfoliation
Some people want their hydrating serum to do more than hydrate. U Beauty’s Resurfacing Compound, its Holy-Grail Multitasking Serum, belongs on a hydration list because of what’s on its INCI: Glycerin seventh, Sodium Hyaluronate ninth, and Hydrolyzed Hyaluronic Acid 13th. Sodium Ascorbyl Phosphate, a Vitamin C derivative, is third. With Glycolic, Lactobionic, and Mandelic Acids and Retinyl Palmitate, a Retinol Ester, it’s a resurfacing step too.
Key features:
Glycerin and two Hyaluronic Acid forms: a humectant base for the serum step.
What U Beauty reports: in a 30-volunteer instrumental study, 93% saw an increase in skin hydration 24 hours after the first use.
One step, then moisturizer: two or three pumps on dry skin after cleansing, left to dry, then sealed with The SUPER Hydrator. Morning, evening, or both.
Best for: dry-feeling skin that also looks dull and wants exfoliation and hydration in the same step.
Tradeoff: the three acids and the Retinol Ester make it a resurfacing serum as well as a hydrating one, and its INCI lists Methyldihydrojasmonate, a fragrance ingredient. U Beauty suggests using it in the evening only if you notice irritation.
Price: $228 for 50 ml, with 30 ml and 15 ml sizes too. Stocked by U Beauty, Sephora, Nordstrom, Bluemercury, and Dermstore.
4. Avène Hydrance BOOST Concentrated Hydrating Serum: best for oily, dehydrated skin
Oily skin can still feel tight, and Avène writes this serum for that: it “Soothes tightness and discomfort common with dehydrated skin.” The humectants stack up early on the INCI: Glycerin third, Diglycerin fifth, Niacinamide eighth, Sodium Hyaluronate ninth, Betaine tenth, and PCA 13th.
Key features:
Five humectants plus Niacinamide, and they’re all in the top 13.
A drop or two: Avène says one to two drops, morning and/or evening.
Face, eye contour, neck, and neckline, per the directions.
Best for: oily or combination skin that feels dehydrated.
Tradeoff: Fragrance is on the INCI, so it’s one to skip if your skin reacts to fragrance.
Price: $42 for 1.0 fl oz.
5. The INKEY List Polyglutamic Acid Serum: best budget pick for oily, dehydrated skin
At $17, it has the lowest listed price here. Polyglutamic Acid is the hero, and The INKEY List claims its 3% complex “holds 4x more moisture than Hyaluronic Acid.” That’s the brand’s claim, and we report it as such. Glycerin is fifth, and Dimethicone is second.
Key features:
Polyglutamic Acid: the humectant the serum is named for.
Layering directions: a pea-sized amount after a hydrator, before moisturizer.
No fragrance on the INCI, and The INKEY List says it suits sensitive skin.
Best for: oily or combination skin that wants a light extra layer of hydration on a budget.
Tradeoff: The INKEY List’s directions put it after another hydrator, so plan on two layers.
Price: $17 for 30 ml.
6. Kate Somerville DeliKate Recovery Serum: best for sensitive skin prone to visible redness
Kate Somerville describes this serum as bringing “a gentle wave of calm to soothe redness and tightness.” The INCI is short on surprises: Glycerin second, three Ceramides at ninth through 11th, and Palmitoyl Tripeptide-8 right after. There’s no fragrance term on the list.
Key features:
Glycerin and three Ceramides: hydration plus lipids for skin that feels tight.
A peptide: Palmitoyl Tripeptide-8, 12th on the INCI.
What Kate Somerville reports: 100% showed significant improvement in hydration after one use. The page doesn’t give the number of participants.
Best for: sensitive skin that looks red and feels tight.
Tradeoff: at $99 for 1 fl oz it’s one of the higher-priced picks, and pick 1 is another fragrance-free option.
Price: $99 for 1 fl oz.
7. L’Oréal Paris Revitalift Derm Intensives 1.5% Pure Hyaluronic Acid Serum: best for dryness around visible fine lines
L’Oréal’s serum states its Hyaluronic Acid strength in the name, 1.5%, and says it’s for “visibly plumped skin.” It’s a short formula, 14 ingredients, with Glycerin second, Sodium Hyaluronate fourth, and Dipeptide Diaminobutyroyl Benzylamide Diacetate, a peptide, eighth.
Key features:
A stated 1.5% Hyaluronic Acid, in a 14-ingredient formula.
Fragrance-free, paraben-free, and non-comedogenic, per L’Oréal.
Widely sold, at a drugstore price.
Best for: dryness that makes fine lines look more noticeable, under a cream.
Tradeoff: L’Oréal’s routine pairs it with its own glycolic cleanser and moisturizer. You don’t need them; any gentle cleanser and moisturizer will do.
Price: $32.99 for 1 fl oz.
8. Dr. Loretta Intense Replenishing Serum: best lipid-rich serum for very dry skin
Not every hydrating serum is a humectant gel. Dr. Loretta’s is built more like a lightweight oil: a silicone-led base (Cyclopentasiloxane, Ethylhexyl Cocoate, Dimethiconol), then Glyceryl Linoleate, Glyceryl Oleate, Glycolipids, and Soybean Oil. The 2020 moisturizer review describes occlusives as reducing water loss, so a formula like this may suit skin that dries out quickly.
Key features:
Lipids rather than humectants as the main event.
What Dr. Loretta reports: in instrumental testing of 33 subjects using it twice a day for four weeks, clinically measured improvement in fine lines, radiance, and transepidermal water loss.
No fragrance ingredient on the INCI.
Best for: very dry skin, or dryness that settles into fine lines, morning and night under a cream.
Tradeoff: it isn’t a humectant serum, so if your skin is oily but dehydrated, picks 4 and 5 fit better.
Price: $75 for 30 ml.
How to use a hydrating serum so it hydrates
Cleanse gently and leave your skin slightly damp.
Apply the serum right away. A few drops or one pump is enough for the face; follow each brand’s amount.
Seal it with a moisturizer before the serum dries down. Humectants pull water in, and the moisturizer helps hold it.
Use one hydrating serum at a time, as Cleveland Clinic suggests, and go from thinnest to thickest.
Mornings, finish with sunscreen.
If you use a Retinoid at night, a hydrating serum and moisturizer can go on before or after it, depending on the Retinoid’s directions. Cleveland Clinic’s Retinol guide notes that Hyaluronic Acid may help counteract some of the irritation Retinol can cause.
A dermatologist can check for eczema or another cause if your skin stays dry, flaky, or itchy even with a serum and a cream.
Frequently asked questions
What is the best hydrating face serum?
For most skin types, including sensitive skin, Vichy Minéral 89. For dry skin, Paula’s Choice Hyaluronic Acid Booster. For oily but dehydrated skin, Avène Hydrance BOOST or, on a budget, The INKEY List Polyglutamic Acid Serum. If you want hydration and exfoliation in one step, U Beauty’s the Resurfacing Compound.
Is Hyaluronic Acid or Glycerin better for hydration?
Both are humectants, and most good hydrating serums use both. Hyaluronic Acid comes in several molecular weights, and Glycerin is a widely used humectant that often sits high on the list.
Can oily skin be dehydrated?
Yes. Oily describes how much oil skin makes, dehydrated describes how much water it holds, and skin can be both. A light, water-based serum with humectants suits that combination.
Should I apply a hydrating serum on wet or dry skin?
Damp skin, for most hydrating serums. The AAD advises applying moisturizing products while skin is still damp. One exception on this list: U Beauty’s directions put the Resurfacing Compound on dry skin.
Should a moisturizer go on after a hydrating serum?
Usually, yes. A serum is mostly humectants, and a moisturizer adds the occlusives and emollients that help keep that water in. Dry skin in particular may feel the difference.
