The primary function of skin lipids is to inhibit bacterial growth. Skin lipids, which include ceramides, cholesterol, and fatty acids, play a crucial role in forming the skin's barrier function. This lipid layer helps to prevent pathogens, such as bacteria, viruses, and fungi, from penetrating the skin and causing infections. Additionally, these lipids aid in maintaining the integrity and flexibility of the skin, reinforcing the overall defense mechanism.

While lipids are also beneficial for facilitating wound healing and maintaining skin hydration, their most critical role is creating a protective barrier that inhibits microbial proliferation. This function is especially significant in preventing skin infections, particularly in compromised or damaged skin areas.
