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.
