Silicon is a trace element naturally present in the body, playing a structural role in connective tissue, cartilage, bone, skin, hair and nails, and supporting the synthesis of collagen and elastin. Silicon reserves decline with age — the body is thought to lose around 80% of its silicon between age 20 and 60. G7 is built on monomethylsilanetriol, an organic form of silicon developed from the research of French chemist Norbert Duffaut in the 1950s, offering markedly better bioavailability than mineral forms like silica.

The formula keeps things simple: organic silicon (monomethylsilanetriol) as the main active ingredient in a neutral, fast-absorbing aqueous gel base, with no paraben and no artificial colouring. The generous 500ml size lasts several weeks to months of regular use, and the light, non-greasy texture absorbs quickly with no residue, so you can get dressed right away.

Also available in capsules: Silicium G7 Activ+.

Apply a small amount of gel to the area of concern — joints (knees, hips, shoulders, wrists, ankles, fingers), back, neck, or any area of skin needing care — and massage gently until fully absorbed. Reapply 2 to 3 times a day as needed. For joints, circular massage helps penetration and local circulation; for the face or décolletage, light tapping is enough. Morning after showering and evening before bed are ideal times. The gel can also be used alongside oral Silicium G7 for a combined internal and external approach.

This gel suits a wide range of people: athletes looking after joints under strain (runners’ knees, swimmers’ shoulders, climbers’ wrists), people over 50 whose silicon reserves decline faster, anyone wanting extra support for skin elasticity and firmness on the face, neck and décolletage, and people doing repetitive movements (desk work) who want to support their wrists and fingers.

For external use only. Do not apply to mucous membranes, open wounds or irritated skin. Avoid contact with eyes; rinse thoroughly with clean water if this happens. Keep out of reach of children. This product is not a medicine and does not replace medical treatment. If joint pain or skin issues persist, consult a healthcare professional. As with any cosmetic product, we recommend a patch test on a small area of skin before first use, especially for sensitive skin. Store in a cool, dry place, away from direct light. Reseal the bottle after each use.

Can Silicium G7 Gel be used on the face?

Yes. Its light, fast-absorbing texture makes it compatible with a daily beauty routine — apply before your usual day or night cream. The organic silicon it contains supports the skin’s structure by encouraging the natural synthesis of collagen and elastin in the deeper layers.

What is the difference between the gel and drinkable Silicium G7?

The gel is applied locally to a specific area for targeted action, while the drinkable form works systemically throughout the body via the bloodstream. The two are complementary — many users combine both for a broader effect.

How long does a 500ml bottle last?

This depends on the area treated and frequency of use. At around 2 applications a day on one or two joints, a bottle typically lasts 2 to 4 months — an economical format for regular use.
