Detailed answer

Glycerin plays a crucial role in hydrating dehydrated skin due to its humectant properties. As a humectant, glycerin has the ability to attract water molecules from the environment and retain moisture within the skin's outer layer. This helps to improve and maintain the skin's hydration levels. Glycerin creates a protective barrier on the skin, preventing excessive water loss through evaporation. Furthermore, it can enhance the skin's natural moisture-binding capabilities, promoting a healthy and supple complexion. Glycerin also functions as an emollient, which means it smooths and softens the skin, reducing any roughness or flakiness associated with dehydration. Overall, glycerin is a valuable ingredient in skincare products formulated for dehydrated skin as it provides essential hydration and helps to improve the overall moisture balance of the skin.
