Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Silicic acid, a bioavailable form of silicon, is incorporated into some skincare products based on both its chemical properties and emerging scientific evidence. Silicon is an essential trace element involved in the synthesis of collagen, a major structural protein in skin. Several studies suggest that silicon supplementation—often as orthosilicic acid—can improve skin strength, elasticity, and hydration. For example, a double-blind, placebo-controlled study published in Archives of Dermatological Research (2005) found that women who took a bioavailable silicon supplement for 20 weeks had improved skin surface characteristics and reduced brittleness of hair and nails.

Mechanistically, silicic acid is thought to support the production of collagen and glycosaminoglycans, both important for skin structure and hydration. However, most research involves oral supplementation rather than topical application; there is limited direct evidence supporting the efficacy of topical silicic acid in skincare. Nevertheless, its inclusion in formulations is justified by its role in skin physiology and the positive outcomes seen in oral supplementation studies.

Overall, while silicic acid’s use in skin care is supported by a moderate level of scientific evidence, particularly for oral forms, more robust and targeted studies—especially for topical application—are needed to confirm its efficacy and optimal use in dermatology.
