The findings show that a high molecular weight proteoglycan administered orally can prevent skin aging driven by exposure to UVB rays over time. Transepidermal water loss (TEWL), erythema, and improvements in skin thickness and hydration were all indicators of this.

The proteoglycan structure is responsible for diverse functions that are exercised on the skin, including preventing the appearance of wrinkles, increasing skin hydration and elasticity, as well as antioxidant effects and protection from oxidative stress caused by an increase in free radicals.
During the aging process, a decrease in the size of endogenous proteoglycans takes place in the extracellular matrix, and skin becomes more fragile and delicate; therefore, an exogenous contribution of this molecule may delay or prevent aging, helping to hydrate and repair the cutaneous tissue.
The research demonstrates that rice ceramide supplementation can significantly improve skin hydration, firmness, elasticity, and wrinkle severity. It also shows a reduction in transepidermal water loss (TEWL), melanin index (MI), and erythema index (EI), suggesting that rice ceramide can effectively improve skin barrier function and reduce pigmentation.
