What function do glycolipids serve in the skin?

Glycolipids play a crucial role in the skin's protective barrier. They contribute to the lipid matrix in the stratum corneum, which is the outermost layer of the skin. This lipid matrix is essential for maintaining the skin's hydration levels and preventing the absorption of harmful substances and pathogens from the environment. By forming a barrier, glycolipids help shield the skin from environmental damage, including UV radiation, pollutants, and other potentially harmful agents, thereby preserving the integrity of the skin and contributing to overall skin health.
