The power of silicium/silicon: why this mineral is essential for your skin and youthfulness

26 aug. 2025

When we talk about skincare from within, you probably think of collagen, hyaluronic acid, or elastin. Yet, there is another less-known but crucial building block that often gets overlooked: Silicium/silicon (also known as silica). This mineral plays a key role in maintaining firm, supple, and radiant skin.

In this article, you’ll discover what silicon is good for, why absorption decreases with age, which forms are most effective, and what people’s experiences with silicon reveal.

What is silicon exactly?

Silicon is the second most abundant element on earth, after oxygen. It is found in skin cells, hair, and bones. It is essential for the formation of connective tissue and plays a role in the production and cross-linking of collagen fibers. You can think of it as the “bridge” that firmly connects collagen fibers, keeping your skin elastic, resilient, and less prone to wrinkles.

Key facts:

  • Silicon = silicium / silica / silicon / kieselguhr.

  • Main source: food (20–50 mg per day), but absorption and availability decline with age (already from the age of 25!).

  • A deficiency leads to weaker cross-linking of collagen, making the skin less firm and radiant.


What is silicon good for?

Many people ask: what is silicon good for? Its benefits go far beyond the skin:

  1. Fighting skin aging
    Silicon supports the formation and connection of collagen fibers, resulting in a firmer skin with fewer fine lines and wrinkles.

  2. Stronger hair and nails
    Because silicon is part of connective tissue, users often notice stronger nails and healthier, shinier hair.

  3. Support for bones and joints
    Silicon contributes to bone mineralization by helping calcium integrate more effectively.

  4. Overall tissue strength
    Silicon plays a role in the structure and resilience of tissues throughout the body.

In short: silicon is good for much more than just your skin, it strengthens your entire connective tissue network.


Silicon and skin aging

Perhaps the most discussed benefit is silicon for skin aging. As we grow older, not only does our collagen decrease, but our body’s ability to absorb silicon also declines. This double effect makes the skin less firm.

By supplementing with silicon, you help maintain optimal collagen cross-linking. The results include:

  • A more resilient skin.

  • Fewer visible wrinkles.

  • Longer-lasting elasticity and a youthful appearance.

The unique properties of silicon

  • Essential for the production and cross-linking of collagen fibers.

  • Indirectly supports hydration by strengthening the skin structure.

  • Works in synergy with vitamin C, which boosts collagen formation and protects cells from oxidative stress. This is why Belène combines silicon with vitamin C in our Silicium Anti-Age Beauty Pill.


Liquid silicon, silica, or silicium tablets: what is the best silicon supplement?

There are different forms of silicon:

  1. Silica (kieselguhr)
    The classic form of silicon, though absorption in the body is limited.

  2. Liquid silicon
    Often promoted as easy to take, but bioavailability varies and absorption remains limited.

  3. Hydrolyzed or patented forms of Silicium
    Such as Mesoporosil®, shown in lab studies to be up to three times more absorbable than other forms. This makes it one of the best silicium supplements available today.

The Belène Silicium Anti-Age Beauty Pill contains 14 mg Mesoporosil® + 12 mg vitamin C – the perfect combination for optimal absorption and collagen support.


How much silicon per day do you need?

Although there is no official daily reference intake, studies and nutrition guidelines suggest a need of 20–50 mg per day from food. Since absorption decreases with age, additional support through supplements can be very beneficial.

The 14 mg of silicium per day in the Belène Beauty Pill is an effective and safe dose to strengthen your skin every day.


Experiences with silicon

Users of silicon supplements often notice:

  • Smoother, more even skin.

  • Fewer fine lines.

  • Stronger nails and less hair breakage.

  • A more radiant, vital look.

Side effects

The good news: at recommended dosages, no significant side effects have been reported. Only extremely high intakes may cause mild digestive discomfort.


Combining silicon with collagen: the ultimate beauty boost

The combination of collagen + silicon is especially powerful:

  • Collagen builds the skin structure.

  • Silicon strengthens the connections (cross-linking) and keeps the network stable.

Together, they provide firmer, more elastic skin that is better protected against signs of aging.
