!What Are Lamellar Granules and How Do They Repair Your Barrier? - SUSHENAH scientific illustration Lamellar granules are your skin's built-in lipid delivery system—tiny packages that release fats exactly where your barrier needs them. These membrane-bound organelles form in the upper epidermis and contain glycoproteins, phospholipids, ceramides, and free sterols. According to research in Andrews' Diseases of the Skin, they "deliver precursors of stratum corneum lipids into the intercellular space." In plain language: they refill the "mortar" between your skin cells. This is the part most products ignore. When your barrier is compromised, you don't just need moisture on top. You need lipids delivered into the gaps—the same way lamellar granules work naturally. Without this repair, moisture keeps escaping. Treating symptoms without addressing the cause means the cycle repeats. Understanding how your skin repairs itself changes what "barrier care" actually means.
