Provided are: a multi-layered lamellar granule comprising a nucleating agent, a ceramide-containing artificial stratum corneum lipid lamellar layer which encases the nucleating agent and a polymer layer disposed on the artificial stratum corneum lipid lamellar layer; and an external skin application composition comprising the same. The external skin application composition shows improved moisturizing and barrier repair capabilities when applied to the skin, which can be advantageously used in cosmetics and pharmaceuticals.
