What Nuru gel is
Nuru gel is a clear, water-based massage gel designed to be extremely slippery. It is the defining ingredient of Nuru massage, whose name comes from the Japanese nurunuru, slippery. It is usually sold as a concentrate and mixed with warm water before use, which makes it thinner, warmer and even more slippery.
The seaweed connection
Nuru gel is traditionally associated with seaweed, and nori is the variety most often mentioned. Modern commercial gels list a seaweed extract among their ingredients, but the slipperiness mostly comes from a water-soluble polymer.
The label of one widely sold gel gives a good picture of a typical formula:
| Ingredient type | Example on the label | What it does |
|---|---|---|
| Base | Purified water | Makes the gel water-based, so it rinses off |
| Humectants | Glycerin, trehalose | Keep the skin moist and the gel from drying out |
| Polymer | PEG-115M | A long-chain polymer that creates the slippery glide |
| Botanical extracts | Kelp (Laminaria japonica), grape seed | Marketed as soothing; the seaweed nods to the tradition |
| Preservatives and stabilisers | Sodium benzoate, disodium EDTA, gluconolactone, sodium hydroxide | Prevent spoilage and adjust pH |
Formulas differ between brands, and venues rarely say which gel they use.
How it differs from massage oil
- Water-based, not oil-based. It sits on the skin rather than soaking in, and rinses off with warm water.
- No oily stains. It does not leave the marks oil leaves on towels and clothes, which is why venues use waterproof air mattresses.
- Odourless and colourless in most formulas, unlike scented massage oils.

How venues use it
In a Nuru venue the gel is mixed with warm water in a bowl and used on an air mattress in a room with a shower. Both people shower before and after the session; the gel washes off easily, but it takes a thorough rinse. The setting is explained in what Nuru massage is and compared with the bath-house format in Nuru vs Soapy.
Skin and safety precautions
- Allergies and sensitive skin. Preservatives and botanical extracts can irritate some people. If you know you react to cosmetic ingredients, tell staff before the session starts.
- Broken skin and eyes. Product labels advise against use on damaged skin and contact with the eyes.
- Slippery floors. Gel makes tiled floors and shower trays very slippery. Move slowly, rinse your feet before stepping off the mattress and use any handrail.
- Rinse well. A residue left on the skin can feel sticky as it dries.

Common questions
What is Nuru gel made of?
Mostly water, plus humectants such as glycerin, a slippery polymer, a seaweed extract and preservatives. Formulas vary between brands.
Is Nuru gel made from seaweed?
It is traditionally associated with nori seaweed, and commercial gels list a seaweed extract, but most of the slipperiness comes from a water-soluble polymer.
Does Nuru gel stain?
It is water-based, so it does not leave oily stains and rinses off with warm water.
Is Nuru gel safe on sensitive skin?
Most people tolerate it, but preservatives and extracts can irritate sensitive skin. Tell staff about allergies, and avoid use on broken skin or near the eyes.
