More than a hyaluronic acid serum
Beyond binding water at the surface, it supports the skin’s own moisture reserves and helps retain hydration for longer at multiple levels.
3 hydration systems
Combines hyaluronic acid and elastin precursors, 5 forms of HA and a proprietary water-retention complex into a multi-level hydration system.
Smoother, more elastic skin
Advanced testing confirms smoother, more elastic skin after 28 days, alongside a reduction in wrinkle visibility.
Results confirmed by advanced testing
Aquasphere is a multi-level hydrating serum with efficacy confirmed not only by consumer in-use testing, but above all by independent instrumental testing — one of the most reliable ways to assess real changes in the skin.
Its efficacy comes from three complementary hydration systems: five forms of hyaluronic acid, precursors that support the skin’s natural production of hyaluronic acid and elastin, and the proprietary Oio Lab Aqua Retention Complex™.
This is more than a standard hydrating serum — rather than providing only surface-level hydration, it helps the skin retain water and stay hydrated for longer. Developed in our Laboratory in Poland.

What makes AQUASPHERE different from a standard hyaluronic acid serum?
Wondering whether Aquasphere is right for you? See the comparison below and discover how it differs from a standard hyaluronic acid serum — a multi-level formula with three complementary hydration systems to help the skin stay hydrated for longer.
| Feature | Standard hyaluronic acid serum | AQUASPHERE |
|---|---|---|
| Hydration system | Often focuses mainly on surface hydration. | 3 complementary hydration systems in one formula: five forms of hyaluronic acid, hyaluronic acid and elastin precursors, and Oio Lab Aqua Retention Complex™ — for multi-level hydration. |
| Testing method | Often relies mainly on consumer feedback. | Instrumental testing measuring real changes in the skin. |
| Hydration results | Specific figures are rarely provided. | +49.5% hydration after 7 days and +56% after 28 days in instrumental testing. |
| Skin barrier | Often lacks data on water loss, while the feeling of comfort may be short-lived. | –13% transepidermal water loss (TEWL) after 7 days — helping the skin retain hydration more effectively. |
| Texture and layering | May not layer well with other skincare products. | A lightweight gel formula that absorbs quickly — ideal on its own or layered under a cream or facial oil. |
| Natural origin | May contain synthetic fragrance and preservatives. | At least 99.38% of ingredients are of natural origin, with no synthetic fragrance and a proprietary 100% natural preservative system. |
What’s inside AQUASPHERE hydrating serum — and why it works?
AQUASPHERE is a multi-level hydrating serum that combines three complementary hydration systems — binding water, supporting the skin’s natural moisture reserves and helping the skin retain hydration for longer.
Here are the selected active ingredients that set the formula apart:
A duo of biotech ingredients derived from fungal biomass that stimulates the skin’s natural production of hyaluronic acid and elastin.
At its core is a hyaluronic acid precursor known as “needle-free hyaluronic acid”. Instead of supplying ready-made hyaluronic acid, it activates the skin’s own synthesis, supporting hydration, bounce and elasticity.
Unlike standard hydrating ingredients, the duo works with the skin’s own processes rather than only binding water at the surface.
Ingredient-level studies showed a 92.7% increase in hyaluronic acid synthesis, a 35.8% increase in elastin synthesis and a 16% improvement in skin elasticity after 28 days.
ECOCERT- and COSMOS-approved ingredients.

ECOCERT- and COSMOS-approved ingredients.
A complex of five forms of hyaluronic acid with different molecular weights, designed to work at multiple levels of the skin — from the surface to deeper layers. As a result, the formula does not focus on a single level of hydration, but delivers a more even, multidimensional effect.
A key component is Sodium Hyaluronate Crosspolymer, a cross-linked form of hyaluronic acid that creates a hydrating micro-network on the skin, binding water and releasing it gradually. It supports long-lasting hydration and helps the skin retain softness, smoothness and comfort for longer.

A proprietary hydration system combining tamarind seed polysaccharides, marine-derived bioactive ingredients from algae and minerals, and Damask rose petal essence. It supports water retention in the skin, reduces moisture loss and helps maintain hydration for longer, rather than delivering only a short-lived effect.
Ingredient-level studies showed a 59% increase in skin hydration after just 30 minutes, with the hydrating effect maintained for up to 7 days after use was discontinued.

How to use AQUASPHERE hydrating serum in your skincare ritual
Aquasphere is a key step in a skincare ritual focused on long-lasting hydration. Use it as part of your daily routine.
Cleanser and mask
As a cleanser: Massage onto the face and neck, then rinse with warm water. Repeat if needed.
As a mask: Apply generously 2–3 times a week, leave on for 15–30 minutes, then rinse off. You can also use it as an overnight mask 1–2 times a week.
Serum
After cleansing and toning, apply a small amount of serum to the face and neck. Gently massage upwards until fully absorbed. Use morning and evening.
Its lightweight gel texture absorbs quickly and layers well with the next steps in your ritual. Follow with a cream, emulsion or facial oil suited to your skin’s needs.
Emulsion
Morning and evening, after cleansing and applying lighter-textured products — such as toner or serum — apply 2–3 pumps to the face and neck. Gently massage using upward motions until fully absorbed.
Its subtle forest scent comes directly from enzymatically extracted fir seed oil from the Vosges.
Cream highlighter
Apply a small amount to the cheekbones, eyelids, inner eye corners or bridge of the nose using your fingertips or a brush. Layer to build your desired glow intensity. You can also apply it to the collarbones and arms.
The creamy formula melts into the skin, leaving a smooth, light-catching sheen and a superfresh, well-rested look.
Available in QUANTUM GLOW — a universal shade that enhances the natural beauty of every skin tone.
Hydration that lasts longer.

Proper Hydration
I have a dehydrated skin and use this product before my moisturising cream. Love it, it has wonderful light texture and absorbs instantly. Will definitely buy couple of bottles for the summer. I love such products for hot weather - it’s not heavy or greasy, it’s water for my skin.
Elena
Love it!
Juliane
Loving it!
This is my first time using it! I love how my skin feels like getting a big glass of water! So hydrated!
Magdalena
Very hydrating and feels so good going on
This serum just feels so good going on. It is light and hydrating and just so lovely to use. I have used many of the Oio products and this, the retinol serum and the Vitamin C facial oil are standouts, but they are all amazing.
Janis
Hydration genie in a bottle
I don't usually write reviews, but this serum is outstanding and really deserves praise. I'm on my 4th bottle and will continue ordering. My skin drinks it up and gets a good bounce from it.
Hege Pedersen
Beautiful product
I had previously received a sample of this and loved it so much I ordered a bottle. It has a clean smell, a wonderful texture that is hydrating without being heavy. It does not cause my oily t-zone areas to break out. Love this!
