What Is Silicium?

And why this trace element is key to skin health…

As we age, it’s natural for our skin to slowly lose the lovely plumpness of our youth. By the time we reach our 40s, in fact, most of us have experienced loss of firmness and less well-defined facial contours. The signs of fatigue can also be more pronounced.

While collagen and elastin—the proteins that keep our skin firm, elastic and plump—naturally decline as we age, so too do our stores of hyaluronic acid and the element Silicium. More commonly known as ‘Silicon’ on the periodic table—and not to be confused with silicone—Silicium plays an important role in collagen synthesis and maintaining the skin’s strength and elasticity. It is also associated with supporting the structural integrity of our hair and nails, as well as bone mineral density.

Unfortunately, however, there has been a surprising lack of research in terms of this critical element.


Pioneering Evidence

At Thalgo, our Research and Development team have long been interested in the effects and benefits of Silicium—even conducting a study in conjunction with the Faculty of Sciences at the University of Nice Sophia Antipolis (now the University of Côte d'Azur). This pioneering study set out to understand the effectiveness of Silicium on the rejuvenation of fibroblast morphology and the optimisation of their communication with the extracellular matrix and proved that Silicium actually restimulates the neo-synthesis of Glycosaminoglycans (GAGs)—compounds which are responsible for drawing water into the skin to maintain hydration—hyaluronic acid, elastin and both type I and type IV collagen.

Utilising this knowledge, Thalgo created their Silicium Marin Complex which combines two active sources of Silicium to restore skin reserves:

  • Silicium grafted onto hyaluronic acid for instant diffusion
  • Silicium encapsulated in marine microsponges for long-lasting bio-absorption


Proven Efficacy

Specifically formulated to combat the visible signs of ageing including more pronounced wrinkles and loss of skin firmness, the complete Silicium Marin regimen—including a day cream, night cream, serum and eye cream—delivers remarkable rejuvenation properties. Each product is supported with independent consumer and laboratory studies, but the hero formula is undoubtedly the Silicium Marin Wrinkle Lifting Serum.

In fact, independent studies featuring 22 volunteers reported after just 42 days of twice a day use the following:

95% complexion is immediately brighter and skin is firmer1

90% wrinkles appear less deep1

+19% improvement in firmness2

+51% improvement in elasticity2

-17% reduction in the number of wrinkles3

While ageing is inevitable, a consistent daily skincare routine using formulas specifically targeted to treat the intrinsic and extrinsic factors that contribute to skin ageing can yield impressive results.
