The full review.
There are approximately ten thousand hyaluronic acid serums on the market at any given moment, so launching a new one requires either extreme value pricing or a genuinely different angle. Glow Recipe chose the latter, and the angle involves mushrooms, Australian plums, and a form of hyaluronic acid that most people haven’t encountered.
Sodium Acetylated Hyaluronate is the quiet star of this formula. Unlike standard sodium hyaluronate, which sits on the skin surface and can be rinsed or rubbed off relatively easily, the acetylated version has an enhanced ability to bind to the skin’s surface proteins. Practically, this means it stays put longer and continues delivering hydration even after you’ve toweled off or applied subsequent products. It’s a meaningful upgrade over conventional HA, and it’s the primary reason this serum feels like it hydrates for longer than many competitors.
But Glow Recipe didn’t stop at one clever HA form. The formula includes five molecular weights in total, each serving a different role in the skin’s hydration architecture. The smallest molecules penetrate into the lower layers of the stratum corneum, providing a plumping effect that visibly softens fine dehydration lines. The larger molecules form a hydrating mesh on the surface, preventing transepidermal water loss and creating that coveted dewy look. It’s a systematic approach to hydration rather than a single-note strategy.
Tremella Fuciformis Polysaccharide — extracted from snow mushroom — adds a layer of hydration that HA alone doesn’t cover. This polysaccharide holds up to 500 times its weight in water, rivaling hyaluronic acid’s capacity, but with smaller molecules that can slip into spaces HA misses. The combination of mushroom polysaccharide with multi-weight HA creates a denser hydration network than either ingredient achieves solo. It also contributes to the serum’s distinctive silky texture.
The Australian superfruit trio — Kakadu plum (Terminalia Ferdinandiana), Davidson plum (Podocarpus Elatus), and Illawarra plum (Pleiogynium Timoriense) — is where the formula gets creative. Kakadu plum contains the highest concentration of vitamin C found in any natural source, roughly 100 times that of an orange. In a hydrating serum, this antioxidant payload serves a specific purpose: it protects the moisture barrier from environmental free radical damage that would otherwise compromise the hydration the HA is delivering. The plums also give the serum its striking purple color, which is entirely natural and blends clear on the skin.
Pantothenic acid (vitamin B5) rounds out the functional ingredients, and its inclusion is more strategic than it might appear. While the HA complex and tremella pull water into the skin, pantothenic acid supports the skin’s own lipid synthesis, helping to repair and strengthen the moisture barrier. This three-part approach — draw water in (HA), hold it there (tremella), and fix the container (B5) — is the kind of layered thinking that separates a well-formulated hydrating serum from a glycerin-in-water solution with a nice label.
Glycerin itself is listed second in the INCI, confirming a substantial concentration. As the most extensively studied humectant in dermatology, glycerin provides a reliable baseline of hydration that works across all humidity levels — including dry indoor environments where hyaluronic acid alone can struggle.
On the skin, this serum is a sensory delight. The watergel texture feels like something between a serum and an essence — it has body without weight, slip without stickiness. It absorbs within seconds, leaving behind a smooth, slightly dewy canvas that takes beautifully to whatever you layer over it. The purple tint, vivid in the dropper, vanishes on contact with the skin. If you’re using it as part of a multi-step routine, it plays well with virtually everything — vitamin C serums, retinol, niacinamide, moisturizers.
Now for the honest part. This serum contains added fragrance — parfum listed as the final INCI ingredient. It smells pleasant, a light fruity scent that fades quickly, but its presence will be a dealbreaker for fragrance-avoidant users and a legitimate concern for the most sensitive skin types. In a formula otherwise well-suited to reactive skin, the fragrance inclusion feels like an unnecessary risk taken for the sake of the brand’s fruit-forward identity.
The price is the other consideration. At $42 for 30ml, this costs roughly four to eight times what a basic hyaluronic acid serum runs. The formulation justifies some of that premium — the acetylated HA, the multi-weight system, the tremella, the superfruit antioxidants — but the hyaluronic acid serum category is extremely competitive, and $42 is a lot to ask when the primary goal is hydration.
Glow Recipe has been building their product line since 2017, and each release has shown increasing formulation sophistication. The Plum Plump serum is a good example of the brand’s evolution — it’s still playful and aesthetically driven, but there’s real science underneath the purple packaging. The inclusion of Sodium Acetylated Hyaluronate signals a brand that’s paying attention to ingredient innovation rather than just following trends.
For anyone seeking a hydrating serum that does more than the bare minimum, this delivers. The multi-weight HA system is genuinely superior to single-weight alternatives, the tremella and B5 provide complementary hydration pathways, and the antioxidant fruit blend adds protective value. Just be aware that you’re paying a meaningful premium for those upgrades, and the fragrance means it’s not quite the universal crowd-pleaser it could have been.

The science.
The Science
The multi-weight hyaluronic acid approach in this serum reflects research demonstrating that HA molecular weight determines its biological activity and skin penetration depth. A 2011 study published in Dermato-Endocrinology showed that low-molecular-weight HA (below 50 kDa) can penetrate into the epidermis and stimulate keratinocyte proliferation, while high-molecular-weight HA (above 1,000 kDa) remains on the skin surface forming a moisture-retaining film. The combination addresses both plumping from within and surface hydration simultaneously.
Sodium Acetylated Hyaluronate represents a meaningful advancement over standard HA. The acetylation process increases the molecule's lipophilicity, allowing it to bind more strongly to skin proteins and resist being washed away. Research published in the International Journal of Biological Macromolecules has shown that acetylated HA provides significantly longer-lasting moisture retention compared to non-acetylated forms — up to 2.5 times the water-holding capacity in some studies.
Tremella Fuciformis polysaccharide has been studied for its moisturizing properties, with research in the Journal of Cosmetic Dermatology demonstrating water-holding capacity comparable to hyaluronic acid. The polysaccharide's smaller molecular structure allows it to penetrate skin layers that larger HA molecules cannot access, providing a complementary hydration pathway.
The Terminalia Ferdinandiana (Kakadu plum) extract provides one of the highest natural concentrations of ascorbic acid, documented at up to 5.9% by fresh weight — a figure that dwarfs most other natural vitamin C sources. Research published in Food Chemistry has confirmed the fruit's potent antioxidant and anti-inflammatory properties, supporting its role as a protective complement to the hydration-focused formula.

Dermatologist Perspective
Dermatologists widely regard hyaluronic acid as one of the safest and most effective hydrating ingredients available. Board-certified dermatologists note that multi-weight HA formulations offer superior hydration compared to single-weight products because they address multiple layers of the stratum corneum. The acetylated HA form in this serum is recognized in dermatological literature for its enhanced skin adhesion. However, dermatologists who treat sensitive or eczema-prone skin would note the fragrance inclusion as a concern — an otherwise well-formulated hydrating serum that unnecessarily introduces the most common cosmetic allergen.
Where it fits in your routine.
Apply 3-4 drops to damp skin right after cleansing and toning. Damp skin gives the hyaluronic acid complex water to draw in. Press the serum into the skin; do not rub. Apply a moisturizer immediately to seal in hydration. In dry or air-conditioned environments, layer a cream or oil over this serum so the HA does not pull moisture out of the skin. Use morning and evening.
At $42 for 30ml, this hyaluronic acid serum costs more than many effective, cheaper options. The formulation includes acetylated HA, a multi-weight system, tremella, and superfruit antioxidants. These additions add value, but users must decide if they justify a 4-8x premium over basic HA serums. A mini size exists for those who want to trial the formula first. For Glow Recipe loyalists who like the brand's fruit-forward ethos and K-beauty-inspired formulations, the price matches the rest of the range.
Use this if you have dehydration, dryness, or dullness and want a hydrating serum more sophisticated than basic hyaluronic acid. It works well for people using drying actives like retinol or exfoliants to replenish moisture. It also suits K-beauty multi-step routine fans who like elegant textures.
People with fragrance sensitivity or those using fragrance-free skincare. Budget-conscious shoppers seeking effective HA hydration at a lower price. Users with very dry skin who need a thick, more occlusive product instead of a lightweight watergel serum.
Product details.
This bouncy, silky watergel has a purple-plum tint from fruit extracts. It is lighter than a traditional serum, acting like a hydrating essence. It absorbs in seconds, leaving a smooth, non-tacky finish and a subtle dewy glow.
Added parfum gives it a light, fruity fragrance. It is pleasant but noticeable, which fragrance-sensitive users should consider.
Glow Recipe uses a glass dropper bottle with a deep plum-purple motif. The dropper dispenses the purple-tinted serum cleanly. This glass bottle is recyclable.
The purple color is striking; it looks like liquid plum in the dropper but applies clear on the skin. The watergel texture glides on without friction and absorbs almost instantly. Skin feels plumper and dewier immediately. The light fruity scent is noticeable during application but fades within minutes. Most skin types experience no stinging or irritation on first use.

The backstory.
The Plum Plump line represented Glow Recipe's entry into the hydration-specific category, moving beyond their watermelon and avocado ranges. The choice of plum as the hero fruit was strategic — it allowed the brand to incorporate Australian native superfruits with exceptional antioxidant profiles while creating a visually distinctive purple product. The serum quickly became one of the brand's bestsellers and spawned an entire plum product line.

Common myths.
Hyaluronic acid pulls moisture out of your skin in dry climates.
This is a half-truth. Standard HA draws water from deeper skin layers in very low humidity. This formula uses Sodium Acetylated Hyaluronate to bind more firmly to the skin surface and glycerin to maintain hydration at all humidity levels. Apply to damp skin and follow with moisturizer to eliminate the concern.
All hyaluronic acid serums are basically the same.
HA molecular weight and form matter. This serum uses five different weights plus an acetylated form that standard HA serums lack. The acetylated version provides longer-lasting hydration because it resists washing away, which makes it different from single-weight HA formulas.
FAQ.
Is the Glow Recipe Plum Plump Serum worth the price?
At $42 for 30ml, this costs much more than basic hyaluronic acid serums. The price pays for a five-weight HA system, including an acetylated form with better skin adhesion, tremella mushroom polysaccharide, and Australian superfruit antioxidants. Whether the price is worth it depends on if you value the multi-weight approach and supporting actives over a simpler, cheaper HA formula.
Can I use the Plum Plump Serum with retinol?
This is a top product to pair with retinol. The multi-weight hyaluronic acid and pantothenic acid maintain hydration that retinol depletes, while the barrier-supporting ingredients reduce retinol-induced flaking and dryness. Apply this serum first on damp skin, let it absorb, then apply your retinol product.
Why is the serum purple?
Australian plum extracts — Kakadu plum, Davidson plum, and Illawarra plum — provide the purple tint via natural anthocyanins. It contains no artificial dye. The color looks vivid in the bottle but turns clear on the skin.
Does this serum contain fragrance?
Yes, this formula contains added parfum/fragrance. The scent is light and fruity, but people with fragrance sensitivities or those who prefer fragrance-free skincare should note this. The fragrance is the last ingredient on the INCI list, which shows a low concentration.
Is this enough hydration for very dry skin?
Probably not on its own. This serum hydrates well but has a lightweight watergel texture. Dry skin types should layer it under a thicker moisturizer or cream. It works as a hydration primer that pulls moisture into the skin, while a moisturizer locks it in. Pairing it with the Glow Recipe Plum Plump Hyaluronic Cream maximizes the system for very dry skin.
