What are ceramides?

Ceramides are a type of lipid, specifically a class of fatty acids, that play a crucial role in maintaining the skin's barrier function. They are a key component of the stratum corneum, which is the outermost layer of the skin, helping to retain moisture and protect against environmental aggressors. This action is essential for keeping the skin hydrated, smooth, and healthy.

While proteins, antioxidants, and vitamins can contribute to skin health, they serve different functions that do not encompass the unique role of ceramides. Proteins are involved in skin elasticity, antioxidants protect against oxidative stress, and vitamins are vital for overall skin health. However, ceramides specifically help to strengthen the skin barrier and prevent water loss, making option related to glycolipid materials the accurate choice.
