Silicic acid, a bioavailable form of silicon, has been investigated for its role in skin health, particularly regarding the support of wrinkles and skin aging. Silicon is an essential trace element involved in the synthesis of collagen and glycosaminoglycans, which are critical for skin structure, elasticity, and hydration. Some clinical studies and reviews suggest that supplementation with silicon—often in the form of orthosilicic acid or choline-stabilized orthosilicic acid—may improve skin texture, increase collagen production, and reduce the appearance of wrinkles. For example, a randomized, double-blind, placebo-controlled trial published in the "Archives of Dermatological Research" (Barel et al., 2005) found that women who took oral choline-stabilized orthosilicic acid for 20 weeks exhibited improved skin surface and elasticity compared to placebo. However, the overall body of evidence remains limited. Most studies have small sample sizes and moderate methodological quality. The mechanism by which silicic acid might exert these effects relates to its contribution to collagen synthesis, but direct evidence linking silicic acid supplementation to significant wrinkle reduction is not robust. While there is some scientific validation for its supportive use in skin health and possibly wrinkles, more high-quality research is needed to confirm its efficacy and optimal usage.
