Aqua (Water): purified water, the base of the formula. Hydroxyethylcellulose: a plant-derived gelling agent that gives the gel its texture. Monomethylsilanetriol (Organic Silicon): the main active ingredient, a source of organic silicon. Phenylethyl Alcohol: a natural preservative for microbiological stability. Sodium Hyaluronate: known for its hydrating properties in topical use. Phytic Acid: a pH regulator and formula stabiliser.

The formula stands out for its short, simple ingredient list, with no synthetic fragrance, a neutral colour, and no rinsing needed after application.

The G5 gel has a non-greasy texture that spreads quickly on the skin, absorbing fast for a dry finish after a few moments of gentle massage, with no sticky feel or visible residue; it’s colourless to slightly translucent depending on the batch, with a discreet or no fragrance.

The gel format allows precise dosing — a small hazelnut-sized amount is usually enough to cover a small area — helping avoid waste and keep track of how much product is used. The 100 ml size offers a comfortable supply for several weeks of regular use.

For external use only. Apply locally to clean, dry skin: dispense a small hazelnut-sized amount of gel, then massage gently until fully absorbed. Use two to three times a day according to personal needs, avoiding contact with eyes, mucous membranes and open wounds. Allow to dry for a few moments before dressing; avoid layering occlusive products (dressings, tight bandages) immediately afterwards.

Stop use if irritation occurs. Keep out of reach of children. Reseal the tube after each use and store away from heat and direct light. Respect the period-after-opening (PAO) shown on the packaging. If in doubt about use or personal sensitivities, seek advice from a qualified professional.

Does the G5 organic silicon gel need to be rinsed off after use?

No, the gel doesn’t need rinsing — simply massage it gently into the skin until fully absorbed, then let it dry for a few moments before dressing; the non-greasy texture and dry finish make rinsing unnecessary.

How long does a 100ml tube last?

This depends on frequency and quantity used; at two to three hazelnut-sized applications a day, a 100 ml tube typically provides several weeks of use, as the format is designed for regular daily use.

Is the G5 silicon gel suitable for all skin types?

The water-based, minimalist formula makes it compatible with most skin types. If you have particularly sensitive or reactive skin, we recommend doing a patch test on a small area first and seeking advice from a professional.
