Hyaluronic Acid Can Actually Dehydrate Your Skin (Here's When)
The internet's favorite hydrator has a counterintuitive dark side — in dry air, a humectant with nothing to seal it can pull water out of your skin instead of into it.
Promising for Dullness
What Makes This Different
Futuredew occupies a category it essentially created — a skincare-makeup hybrid that uses real plant oils and humectants alongside reflective minerals to deliver both instant cosmetic glow and long-term hydration benefits. Unlike highlighters or illuminating primers, it provides genuine skincare ingredients (squalane, rosehip oil, evening primrose oil, hyaluronic acid) alongside the visual sparkle.

Futuredew delivers exactly what Glossier promises — instant, lit-from-within glow plus genuine long-term hydration from quality plant oils. It's a category-defining product that works beautifully on dry to normal skin, but the reliance on reflective particles for immediate impact and the rosemary essential oil limit its appeal for sensitive or oily skin types.

Review
Full Review
There is a specific look that Glossier built a billion-dollar brand around, and if you have spent any time on beauty social media since 2014, you know exactly what it is: skin that appears to have been kissed by morning light, slightly wet but not sweaty, luminous in a way that suggests either exceptional genetics or a very expensive multi-step routine. Futuredew is Glossier's attempt to sell that look in a single bottle, and the audacity of the concept is almost as interesting as the product itself.
The formula sits between a facial oil and a serum, and the oil-serum hybrid label is genuinely accurate rather than marketing decoration. Water and glycerin lead the list, establishing the hydrating base. Squalane comes immediately after — a lightweight emollient that mimics the skin's own sebum so closely it absorbs without the heavy residue traditional oils leave behind. Then the supporting botanicals: jojoba, evening primrose, grape seed and rosehip, each contributing a different essential fatty acid profile. Sodium hyaluronate handles the humectant side. It is a well-chosen oil blend by any standard.
But here is the part of Futuredew that deserves honest disclosure: a meaningful share of the instant glow comes not from the skincare oils but from reflective minerals. Mica, titanium dioxide, tin oxide and iron oxides sit near the end of the list, the same light-scattering particles used in liquid highlighters and illuminating primers. When you pump Futuredew onto your skin and marvel at the immediate glass-skin effect, you are watching physics as much as skincare — light bouncing off microscopic mineral particles suspended in an oil-serum base.
That is a clarification rather than an accusation. Plenty of products in the glow-serum category lean on the same trick, and this one is at least transparent about what it is. The difference is that the supporting cast — squalane, evening primrose, rosehip, hyaluronic acid — is doing real work underneath. After two to four weeks of daily use, the glow stops being entirely about the mica and starts being partly about skin that is genuinely better hydrated. Rosehip oil in particular carries naturally occurring trans-retinoic acid alongside a high linoleic acid content, both of which contribute mild smoothing and brightening over time. Evening primrose brings gamma-linolenic acid for barrier support. These are not placeholders.
The engineering behind the texture is worth a moment too. Isoamyl laurate and isohexadecane give the formula its startling lightness for something carrying this much oil; polyglyceryl-3 polyricinoleate and a pair of polyglyceryl esters keep the oil and water phases married; disteardimonium hectorite and a little castor oil suspend the mineral particles so they do not settle into a golden sludge at the bottom of the bottle. The glass pump dispenses a controlled dose, which matters, because the difference between 'lit from within' and 'visibly damp' is roughly one extra pump.
On dry to normal skin, the finish is genuinely lovely — a dewy luminosity that holds for hours and reads as healthy skin rather than the aggressive sparkle of a highlighter. On oily skin, that same dewiness tips into greasiness, particularly through the T-zone, and the reflective particles amplify shine that is already there in a way that lands closer to 'sweaty' than 'glowy.' Combination skin can have it both ways by placing it deliberately: cheekbones and the high points, nothing in the center panel.
One ingredient warrants attention. Rosmarinus officinalis leaf oil is functional — it brings antioxidant activity — but it is an essential oil, capable of irritating reactive skin, and it gives the formula a faint herbal scent. Futuredew is therefore not fragrance-free, despite the brand's general minimalism on that front. For anyone whose skin has already told them essential oils are off the table, that alone settles it. The isoamyl laurate is the other flag, comedogenic enough for acne-prone skin to warrant a patch test, and the oil content rules the product out of a Malassezia-avoidant routine altogether.
As a primer it performs better than most things sold as primers. A single pump under a skin tint or light foundation gives a base that glows through the makeup instead of fighting it. At night it is a pleasant final step that leaves skin noticeably softer by morning. That versatility is real, and it is part of why a bottle stretches three to four months even at daily use.
The price is the honest sticking point. Twenty-four dollars for one ounce is prestige positioning for a formula built on glycerin, squalane and plant oils — commodity ingredients available for far less elsewhere. What the premium buys is the specific ratio, the reflective blend that produces the signature effect, and the brand experience, which for a lot of buyers is not a small thing. A plain squalane oil delivers much of the hydration for a fraction of the money; what it will not deliver is the look, and the look is what people are actually here for.
Which makes Futuredew a very Glossier product: it sells a feeling as much as a function, it is beautiful on the skin, and it carries just enough genuine skincare to earn the word serum rather than highlighter. On dry-to-normal skin that wants one product doing two jobs, it is well executed. Strip away the mystique and the mica, though, and what remains is a nice oil-serum blend at a premium price — which is either a fair trade or a hard pass, depending entirely on how much you want that glow.
Formula
Key Ingredients
The hero actives that drive this product's performance.
| Ingredient | Function | Evidence |
|---|---|---|
| Squalane | The primary emollient oil in this formula, providing lightweight, non-greasy hydration that mimics the skin's own sebum. Listed third after water and glycerin, squalane forms the 'oil' half of this oil-serum hybrid, delivering the slip and luminosity that gives Futuredew its signature wet-look finish without the heaviness of traditional facial oils. | Established mechanism for Dryness · established mechanism |
| Glycerin | The 'serum' component of this hybrid — listed second, glycerin is the primary humectant drawing water into the skin from the environment. Working alongside squalane, it provides the hydration underneath while the oils provide the glow on top, creating the dual-phase moisture effect that defines this product. | Established mechanism for Dryness · established mechanism |
| Jojoba Seed Oil | A liquid wax ester rather than a true oil, jojoba closely resembles the skin's natural sebum composition. In this formula, it adds conditioning depth to the squalane base while contributing to the smooth, non-sticky application that sets Futuredew apart from heavier facial oils. | Established mechanism for Dryness · established mechanism |
| Evening Primrose Oil | Rich in gamma-linolenic acid (GLA), an omega-6 fatty acid that supports barrier function and has anti-inflammatory properties. Adds nutritive depth to the oil blend, providing essential fatty acids that the skin cannot produce on its own. | Not yet assessed |
| Rosehip Fruit Oil | Naturally rich in trans-retinoic acid and linoleic acid, rosehip oil contributes mild brightening and skin-smoothing benefits over time. Works alongside the evening primrose and grape seed oils to create a multi-source essential fatty acid profile that supports long-term skin texture improvement. | Not yet assessed |
| Sodium Hyaluronate | A low-molecular-weight form of hyaluronic acid that penetrates more readily than the parent molecule, providing deep hydration that plumps skin from within. Complements the glycerin humectant layer, adding a water-binding capacity of up to 1,000 times its weight. | Established mechanism for Dehydration · established mechanism |

Evidence
Science & Expert Perspective
The Science
Futuredew's skincare efficacy rests primarily on its oil and humectant blend. Squalane, the leading oil ingredient, is a hydrogenated form of squalene — a lipid naturally produced by human sebaceous glands. Because it mirrors the skin's own chemistry, squalane integrates into the lipid matrix of the stratum corneum rather than sitting on top, providing emollient benefits without occlusion. A 2020 review in the International Journal of Cosmetic Science noted that squalane demonstrates both emollient and antioxidant properties, with the added benefit of high oxidative stability compared to its unsaturated precursor squalene.
Evening primrose oil (Oenothera biennis) is notable for its gamma-linolenic acid (GLA) content — typically 7-10% of its fatty acid profile. GLA is a precursor to dihomo-gamma-linolenic acid (DGLA) and subsequently to anti-inflammatory prostaglandin E1. Topical application of GLA-rich oils has shown promise in supporting barrier function in atopic skin, though most clinical evidence comes from dietary supplementation rather than topical use.
Rosehip fruit oil (Rosa canina) contributes a different fatty acid profile, rich in linoleic acid (44-49%) and alpha-linolenic acid (33-36%). It also contains naturally occurring trans-retinoic acid at low concentrations, which may contribute to mild photo-aging repair with sustained use. A 2015 clinical study published in the Journal of Cosmetics, Dermatological Sciences and Applications found that rosehip oil significantly improved skin moisture, elasticity, and roughness after eight weeks of twice-daily application.
The reflective mineral component (mica, titanium dioxide, iron oxides) provides purely cosmetic benefits — these inorganic particles scatter and reflect visible light, creating the appearance of smoother, more luminous skin immediately upon application.
Dermatologist Perspective
Dermatologists generally view oil-serum hybrids as beneficial for dry to normal skin types that need both humectant and emollient hydration. Dermatologists in everyday practice often note that squalane is among the best-tolerated facial oils due to its biomimetic properties, and the inclusion of rosehip and evening primrose oils adds essential fatty acids that support barrier function. However, clinicians consistently caution that the rosemary leaf oil in this formula is an essential oil and potential sensitizer, and the reflective mineral particles, while cosmetically appealing, provide no therapeutic benefit. Dermatologists typically recommend applying Futuredew after active serums (vitamin C, retinol) and before sunscreen in the morning routine.
Guidance
Usage & Recommendations
How to Use
Apply 1-2 pumps to clean skin as the last step of your skincare routine (after serums, before sunscreen in AM). For a subtle glow, use one pump and press into skin with palms. For a more dramatic dewy effect, use two pumps and blend outward from the center of the face. Can be mixed into moisturizer or foundation for a diluted glow. At night, apply as the final step after all treatments. Avoid applying to oily areas if combination skin — focus on cheeks, forehead, and chin where you want luminosity.
Value Assessment
At twenty-four dollars for one ounce, Futuredew positions itself as a prestige serum, though the core ingredients — glycerin, squalane, plant oils — are available at significantly lower price points from budget brands. What you are paying for is the specific formulation ratio, the reflective particle blend that creates the signature Glossier glow, and the brand experience. The product lasts three to four months with daily use, bringing the effective cost down. As an established product from a brand with six-plus years of track record and Leaping Bunny certification, the pricing is defensible but not a value play. Budget-conscious consumers can replicate much of the hydration benefit — though not the exact glow effect — with a pure squalane oil at a fraction of the cost.
Who Should Buy
Dry to normal skin types who want a single product that delivers instant dewy glow plus long-term hydration benefits. Ideal for minimalists who want to collapse multiple routine steps into one, and for anyone who loves the glass-skin aesthetic and wants it in a format that also provides genuine skincare.
Who Should Skip
Oily skin types who already struggle with excess shine. Anyone sensitive to essential oils (rosemary leaf oil is present). Acne-prone skin should patch test due to isoamyl laurate. And anyone who wants pure skincare without cosmetic additives — the reflective particles make this a hybrid product by nature.

Background
The Story Behind This Product
Launched in October 2019, Futuredew was Glossier's attempt to bottle the brand's signature 'dewy skin' aesthetic into a single product. The concept was born from the observation that achieving the Glossier look typically required layering multiple products — serum, oil, highlighter. Futuredew collapsed that routine into one step, blending genuine skincare oils with reflective minerals for instant and long-term luminosity.
About Glossier Established Brand (5–20 years)
Glossier was founded in 2014 by Emily Weiss, growing out of the influential beauty blog Into The Gloss. The brand is Leaping Bunny certified cruelty-free and has built a devoted following through direct-to-consumer sales and community-driven product development, though it does not have clinical or dermatologist-developed origins.

Myth vs. Reality
Common Myths
Myth
Futuredew is just a highlighter marketed as skincare.
Reality
While it does contain mica, titanium dioxide, and iron oxides for instant reflective glow, the formula is built on genuine skincare ingredients — squalane, glycerin, jojoba oil, evening primrose oil, rosehip oil, and hyaluronic acid. Over time, these ingredients provide real hydration and barrier support benefits independent of the cosmetic glow effect.
Myth
Oil-based products always clog pores and cause breakouts.
Reality
Squalane, the primary oil in Futuredew, has a comedogenic rating of 0-1 and closely mimics the skin's natural sebum. Jojoba oil is similarly well-tolerated. However, isoamyl laurate in this formula can be comedogenic for some individuals, so patch testing is advisable for acne-prone skin.
FAQ
Frequently Asked Questions
Is Glossier Futuredew a skincare product or a makeup product?
It's genuinely both. The base is built on skincare ingredients — squalane, glycerin, jojoba oil, rosehip oil, evening primrose oil, and hyaluronic acid — that provide real hydration and barrier support. But it also contains mica, titanium dioxide, and iron oxides that create an instant reflective glow similar to a liquid highlighter. Over weeks of use, the skincare benefits accumulate independently of the cosmetic effect.
Can you wear Glossier Futuredew under makeup?
Yes, and it works particularly well as a luminizing primer. Apply one pump before foundation for a dewy, lit-from-within base. However, if you use a matte foundation, the dewy effect may be partially neutralized. It pairs best with skin tints, tinted moisturizers, and light-coverage foundations that let the glow show through.
Is Glossier Futuredew good for oily skin?
It's not ideal for oily skin types, especially during the day. The oil content and reflective particles can amplify shine on already-oily skin. If you have oily skin and want the glow effect, try using it only at night as a nourishing treatment, or mix a single pump into your moisturizer to dilute the intensity.
Does Glossier Futuredew have SPF?
No. While it contains titanium dioxide and iron oxides, these are present for cosmetic reflective purposes at concentrations far below what would provide meaningful sun protection. Always apply a dedicated sunscreen over or under Futuredew for UV protection.
Is Glossier Futuredew fragrance-free?
No. It contains rosemary leaf oil (Rosmarinus Officinalis Leaf Oil), which imparts a mild herbal scent and is technically a fragrant essential oil. While rosemary oil has antioxidant properties, it can be irritating for those with essential oil sensitivities. If you react to essential oils, patch test before committing.
