Lamellar bodies are the lipid‑secreting organelles found in keratinocytes. As these skin cells mature, they package lipids such as ceramides, cholesterol, and fatty acids into these granules and release them into the space between cells to form the lamellar lipid sheets of the stratum corneum. This lipid barrier is essential for preventing water loss and protecting against environmental threats. The Golgi apparatus handles general processing and packaging, lysosomes break down waste, and peroxisomes participate in lipid metabolism and detoxification but do not serve as the specialized lipid‑secreting organelles in keratinocytes.
