What is the function of sebaceous glands?

Sebaceous glands play a crucial role in maintaining skin health by producing sebum, a natural oil that helps to moisturize and protect the skin. Sebum acts as a barrier, preventing the moisture within the skin from escaping and helping to maintain its elasticity and suppleness. Additionally, this oily substance has antibacterial properties that can protect the skin from harmful microbes. The presence of sebum on the skin's surface also aids in creating a natural, protective film that keeps the skin hydrated.

Understanding this function is essential for estheticians, as it underscores the importance of maintaining a balanced skin environment. Over-cleaning the skin or using products that strip natural oils can disrupt the activity of sebaceous glands, leading to issues such as dryness or increased oil production, potentially resulting in acne or other skin concerns. Therefore, promoting skin health involves recognizing and supporting the function of these glands rather than overwashing or mismanaging oil levels.
