Silicon is an essential trace element that has garnered scientific interest for its role in supporting the skin and connective tissues. Research indicates that silicon is a critical component in the synthesis and stabilization of collagen and glycosaminoglycans, which are fundamental to the structure and elasticity of skin. Several studies have demonstrated that dietary supplementation with bioavailable forms of silicon, such as orthosilicic acid, may improve skin properties, including hydration, elasticity, and texture. For example, a double-blind, placebo-controlled study published in 2005 found that women who took a silicon supplement for 20 weeks experienced significant improvements in skin surface characteristics and mechanical properties compared to the placebo group.

Despite these promising findings, the overall evidence is moderate rather than robust. The number of high-quality human trials remains limited, and the long-term effects of supplementation are not fully established. However, the biological plausibility is strong, considering silicon’s function in connective tissue health. Silicon is also found in whole grains, fruits, and vegetables, and deficiencies are rare in populations consuming a balanced diet. In summary, while scientific evidence supports the use of silicon for skin health, particularly related to collagen production and skin quality, further research is warranted to confirm optimal dosing and long-term safety.
