Organic Silicon: Boosting Collagen for Firmer, Youthful Skin

Skin sagging is one of the most visible signs of skin aging. It appears when collagen and elastin, the proteins that give structure and elasticity to the dermis, are produced less or less efficiently. The result is thinner, less firm skin that is less able to recover from gravity and movement.

Organic silicon acts directly on this process: it is an essential cofactor in the synthesis of collagen and elastin, which makes it one of the most important trace elements for maintaining skin firmness from within.

What is flaccidity and why does it appear?

Sagging is not just an aesthetic issue. It is the visible consequence of biological changes in the dermis that begin before the age of 30.

Loss of collagen after the age of 25, collagen production decreases by approximately 1% per year. Type I and III collagen, which represents 70-80% of dermal collagen, is responsible for skin firmness and volume. When it decreases, the skin loses its internal architecture and gives way.

Elastin degradation elastin allows the skin to regain its shape after stretching. With aging, elastin fibers fragment and the tissue loses its ability to recoil. Unlike collagen, elastin practically does not resynthesize in adulthood, so its preservation is a priority.

Reduction of glycosaminoglycans (GAGs), hyaluronic acid and chondroitin sulfate form the extracellular matrix that retains water in the dermis. Their decrease causes loss of volume and turgor, contributing to the appearance of sagging skin.

Factors that accelerate this process beyond natural aging: accumulated sun exposure (main cause of extrinsic aging), smoking, rapid weight loss, pregnancy, sedentary lifestyle and sustained nutritional deficits.

How organic silicon acts on flaccidity

Silicon is the third most abundant trace element in human connective tissue. Its concentration is especially high in the skin, where it fulfills specific structural functions that differentiate it from other skin care supplements.

Fibroblast stimulation Fibroblasts are the dermal cells responsible for producing collagen, elastin and glycosaminoglycans. Research published in Archives of Dermatological Research shows that stabilized orthosilicic acid stimulates the proliferation and activity of human dermal fibroblasts, significantly increasing type I collagen synthesis.

Cofactor in collagen synthesis Silicon acts as a cofactor for the enzyme prolyl hydroxylase, responsible for proline hydroxylation during collagen maturation. Without this step, collagen does not acquire the structural stability necessary to fulfill its function in the dermis.

Elastin crosslinking Silicon is involved in the crosslinking of elastin fibers, a process that gives them their functional stability. Without proper crosslinking, elastin degrades more rapidly and loses its ability to keep the skin elastic.

Synthesis of glycosaminoglycans Silicon is also involved in the production of GAGs, contributing to the maintenance of dermal volume and hydration that support the skin's architecture.

The Spanish Society of Aesthetic Medicine (SEME) has recognized that collagen stimulation through inducers such as organic silicon represents one of the most relevant lines of current aesthetic medicine treatments.

Why the form of silicon matters: bioavailability

Not all silicon supplements have the same effect. The reason is bioavailability: the amount of silicon that the body can actually absorb and utilize.

Silicon in plant foods (oats, horsetail, brown rice) has a bioavailability of about 3-4%. Silicon dioxide used in many powdered supplements has very low bioavailability because the body considers it a contaminant and eliminates it.

Organic silicon in the form of stabilized orthosilicic acid, developed from the work of Dr. Loïc Le Ribault(a geologist with doctorates from the Sorbonne and Orsay, with more than 30 years of research in organic silicon), is formulated in short monomeric chains that prevent its crystallization in the body. This configuration allows the body to assimilate and use it directly, rather than eliminating it as waste.

The practical difference: the same amount of silicon ingested in different formats has very different effects. What is relevant is not how much silicon you take but how much is actually absorbed by the body.

Sagging due to weight loss: a special case.

Sagging that appears after significant weight loss has a different dynamic. The skin, which had adapted to a larger volume, does not regain its former elasticity with the same speed as adipose tissue is lost. This occurs especially when weight loss is rapid or when there is a nutritional deficit associated with the process.

In these cases, support for collagen and elastin synthesis is especially relevant, as the skin needs the structural cofactors to try to recover its architecture.

Internal and topical approach: why they work differently

Sagging care can be approached from the inside (oral) or from the outside (topical). They are different mechanisms that complement each other.

Oral route: organic silicon taken in liquid form reaches the dermal tissues through the bloodstream. It acts as a cofactor in the synthesis of collagen and elastin from within, systemically. Its effects are progressive and require consistency.

Topical: silicon gel acts locally in the area of application. The small molecules of orthosilicic acid penetrate into the intradermal layer, where they locally stimulate tissue renewal processes. Unlike many cosmetics, its penetration into deeper layers is medically proven.

Combined approach: the simultaneous use of oral and topical silicon acts on two fronts: systemic (tissue nourishment from the inside) and local (direct stimulation in the treated area). It is the most comprehensive approach to address sagging in a holistic manner.
