01 · Anatomy of the dermal matrix
When skin loses firmness, silicon levels have already fallen.
Skin changes gradually with age and other factors. Organic silicon is the common cofactor for collagen I, elastin, and keratin — the three proteins that support all three tissues.
Three tissues · three proteins
Three tissues · one structural cofactor — organic silicon acts on all three in parallel, not separately.
Type I collagen synthesis
Silicon is an essential cofactor for the enzymes that assemble type I collagen fibers — the main structural protein in the dermis.
Skin elasticity and recovery
Silicon stabilizes elastin and proteoglycan fibers, the molecules that allow skin to return to its shape after repeated facial movements.
Stronger hair and nails
Specific studies have measured parameters of hair and nails, tissues made up of keratin.
Hydration and barrier function
Silicon strengthens the hyaluronic acid network that retains water in the dermis. Skin hydration is related to the appearance of the skin.

Frequently asked questions about silicon and beauty.
01When will I notice results in my skin, hair, and nails from taking G7 Beauty?+
There is no general timeframe: each study specifies when measurements were taken. In the Polonini 2019 study (double-blind · 150 days), a 25% reduction in wrinkles was measured (Visia, Ferreira 2018), along with subjective improvements in hair hydration and skin radiance after 5 months.
02Does it help with alopecia, or only with fine hair?+
If you have persistent or diagnosed hair loss, consult a healthcare professional.
03Can I take G7 Beauty with hydrolyzed collagen?+
Yes. If you combine supplements, check the total composition and follow the directions for each one. No interactions have been documented in 23 years.
04What is the difference between G7 Beauty and G7 Original for skin?+
G7 Beauty is the targeted formula with added biotin + zinc + vit C for hair, nails, and skin. G7 Original is the liquid base formula that provides full systemic support (bones + joints + skin at the same time). If your priority is appearance, choose G7 Beauty. If you want all-round support, choose G7 Original.
05What has been studied about nails?+
Specific studies have measured nail parameters. Their results relate to the conditions of each trial.
06What dose of G7 Beauty should I take?+
The standard dose is 2 capsules a day, one with breakfast and the other with lunch. Always read the package instructions and, if in doubt, consult your healthcare professional.
