Clinical and instrumental evaluation of a food supplement in improving skin hydration

Abstract

Topically applied cosmetic products can be helpful in improving skin hydration. The study shows how oral supplementation could be helpful in improving and preventing the skin dehydration. A total of 32 healthy female volunteers entered the study. Of which, 16 were treated with a food supplement based on vegetable ceramides, amino acids, fish cartilage, antioxidants and essential fatty acids for 40 days and 16 with placebo. The results of the clinical and instrumental evaluations carried out in this study, have highlighted how the active treatment is effective in improving skin hydration and in reducing the cutaneous smoothness and roughness and the depth of furrows, in comparison to the placebo. In fact, concerning several important parameters, as stratum corneum hydration and skin roughness, the improvement measured exceeded 25%. We therefore suggest that a combination of treatments (oral and topical) can be more effective in improving skin hydration.

The moisturizing effect of a wheat extract food supplement on women’s skin: a randomized, double‐blind placebo‐controlled trial

“…However, few of these studies have assessed the effect of SC lipids, in particular ceramides, for which the results have been promising. These studies supported the efficiency of ceramides from different plants (konjac, rice, corn) in improving skin hydration [20][21][22]. All together, these findings indicate that an oral supplementation of ceramides could improve skin hydration.…”

<i>In vivo</i> Evaluation of a Cosmetic Emulsion Containing Soybean Extract for Anti-Aging

“…Soybean extracts was found to instigate the synthesis of collagen and elastin, and to boost the correct assembly of new elastin fibers, providing a complete protection and restoration to the dermal extracellular matrix [15]. Soybeans extract also protected elastic fibers produced by cultured fibroblasts from degradation by exogenously-added elastases [16].…”
