The Effects of Rice Ceramide Supplementation in Improving Skin Health

Detailed Summary

Ceramides have been added to newer cosmetic products to improve skin barrier function and exogenously replenish skin ceramides. Of the stratum corneum intercellular lipids, Ceramides are the most effective at restoring barrier function and increasing skin hydration. Different ceramides have been incorporated into cosmetic formulations, but understanding the differences between ceramides used in formulations, or even identifying ceramides in formulations can be complex. This is mostly because of an archaic nomenclature system that is fundamentally flawed based on current scientific evidence. In the recent past, due to the unique bioactive components of rice, it has been explored to a certain limit for its components. Further, much attention has been paid to the plant ceramide with its incorporation into cosmetics and food preparations owing to its safety in contrast to animal/synthetic origin. There are reports on plant ceramide deciphering its protective effects on human skin by preventing moisture loss. It has been anticipated that ceramides, fatty acids, and cholesterol in combination with hydrocortisone (HC) can be an useful therapeutic agents against xerosis and atopic dermatitis. The beneficial effects of oral intake of plant-derived ceramides for skin hydration and skin barrier reinforcement have been established in several studies involving animal models as well as human subjects. Ingestion of konjac ceramides has also shown positive effects in atopic dermatitis patients as well as healthy volunteers. Results showed improved skin symptoms and reduced skin allergic responses. The foregoing studies support the beneficial effects of oral intake of plant ceramides and their potential complementary and alternative therapeutic applications in the restoration and maintenance of skin barrier function. However, the findings from human study are still very limited, more detailed and comprehensive studies are still required to document the clinical efficacy of oral supplementation of ceramides. Thus, this study aims to evaluate the effects of rice ceramides consumption in improving skin health.
