BiON Pure Hydration Hyaluronic Serum from BiON Research is a streamlined, four-ingredient hydration serum built around sodium hyaluronate, the salt form of hyaluronic acid that penetrates skin efficiently to restore moisture where it has been lost.
Key Benefits
Deep, lasting hydration Sodium hyaluronate draws moisture from the environment into the skin and can hold up to 1,000 times its weight in water, helping to plump skin from within and reduce the appearance of fine lines caused by dehydration.
Smoother, firmer-looking skin By replenishing water content in skin cells, this serum visibly softens the look of sagging areas and surface creasing without any heavy occlusive ingredients.
A clean, minimal formula anyone can use With only four ingredients and no fragrance, parabens, or unnecessary additives, this serum works with virtually every skin type and layers cleanly under any moisturizer or treatment without pilling or interference.
If your skin feels tight, looks dull, or has lost its firmness, dehydration is often the underlying cause. BiON Pure Hydration Hyaluronic Serum is ideal for anyone whose skin lacks water rather than oil, including oily and combination skin types that are frequently over-stripped by acne treatments or harsh cleansers.
Dry and mature skin types will find this serum especially useful as a daily hydration foundation layered beneath moisturizers and targeted treatments. Because the formula contains gluconolactone, a gentle polyhydroxy acid, it also suits those with sensitive or compromised skin who want mild resurfacing benefits alongside deep hydration.
The fragrance-free, paraben-free formula makes it appropriate for even the most reactive skin, and its simplicity means it fits easily into any routine without disrupting other actives you may already be using.
Apply this serum to skin that is still slightly damp after toning rather than waiting for skin to dry completely. Sodium hyaluronate draws moisture into the skin, and giving it existing surface water to work with helps it deliver noticeably better results.
Prepare: Cleanse and tone skin, then leave skin slightly damp before applying.
Apply: Dispense one to two drops onto damp fingertips and massage thoroughly into the face and neck.
Frequency: Use morning and evening. Follow with your moisturizer or any additional serums. When used in the morning, always finish with a broad-spectrum SPF before sun exposure.
Key Ingredients

Hyaluronic Acid: Naturally occurring in the skin, provides intense hydration and plumps and improves skin barrier function by attracting and retaining moisture.

Deionized Water (Aqua), Sodium Hyaluronate (Hyaluronic Acid), Gluconolactone, Sodium Benzoate
What makes BiON Pure Hydration Hyaluronic Serum different from other hyaluronic acid serums?

BiON Pure Hydration Hyaluronic Serum uses a deliberately minimal four-ingredient formula built around sodium hyaluronate, the salt form of hyaluronic acid that is well absorbed by the skin. There are no fillers, fragrances, or unnecessary additives, which means the active ingredients are doing all of the work. The inclusion of gluconolactone, a gentle polyhydroxy acid, also sets this serum apart by providing mild resurfacing and barrier-supporting benefits alongside hydration.

What is sodium hyaluronate and how does it work in BiON Pure Hydration Hyaluronic Serum?

Sodium hyaluronate is the sodium salt form of hyaluronic acid, a molecule naturally found in the body that is known for its ability to hold up to 1,000 times its weight in water. In BiON Pure Hydration Hyaluronic Serum, it works by drawing moisture from the surrounding environment into the skin and helping to retain it, which visibly reduces the appearance of fine lines and restores a firmer, more hydrated look over time.

What is gluconolactone and why is it included in BiON Pure Hydration Hyaluronic Serum?

Gluconolactone is a polyhydroxy acid (PHA) that gently exfoliates the surface of the skin while also supporting the skin barrier. Unlike alpha hydroxy acids, it has a larger molecular structure that works more slowly and with significantly less irritation potential, making it appropriate for sensitive skin. Its presence in BiON Pure Hydration Hyaluronic Serum means you are getting mild resurfacing benefits alongside deep hydration in a single step.

Is BiON Pure Hydration Hyaluronic Serum safe for sensitive or reactive skin?

Yes. The formula contains only four ingredients, is fragrance-free and paraben-free, and relies on gluconolactone rather than stronger exfoliating acids. This combination makes it one of the more accessible hydrating serums for those whose skin does not tolerate complex or heavily fragranced formulas. If you have specific concerns about reactivity, our estheticians are happy to help you assess fit through a free skincare consultation.

Can BiON Pure Hydration Hyaluronic Serum be used with other serums and moisturizers?

Yes, and layering is actually encouraged. Because this serum has such a clean, lightweight formula, it sits well beneath other treatments and moisturizers without pilling or interfering with actives. Apply it first to damp skin, allow it to absorb briefly, then follow with any additional serums or a moisturizer.

Is BiON Pure Hydration Hyaluronic Serum appropriate for oily or acne-prone skin?

It is. Oily and acne-prone skin types are often dehydrated because acne treatments and clarifying cleansers strip water from the skin, which can actually trigger more oil production as compensation. This serum replenishes water content without adding oil or clogging pores, making it a practical hydration step even within an active acne routine.

Do I need to use SPF after applying BiON Pure Hydration Hyaluronic Serum?

Because this serum contains gluconolactone, a polyhydroxy acid, it is best practice to apply a broad-spectrum SPF whenever you use it in the morning before sun exposure. Exfoliating acids of any strength can increase skin sensitivity to UV light, and consistent SPF use protects your results and your skin barrier over the long term.
