Disclosed is a technique for allowing an active ingredient as an agent for improving or maintaining the dermal environment to reach a dermis. Specifically disclosed is a vesicle comprising the following components 1) to 3) : 1) an α,ε-bis (γ-N-(C10-30) acylglutamyl) lysine and/or a salt thereof; 2) ceramide and/or a derivative thereof; and 3) one or more selected from a glycerin fatty acid ester, a polyglycerin fatty acid ester and a pyroglutamic acid glycerin fatty acid ester. The acyl group in the α,ε-bis (γ-N-(C10-30) acylglutamyl) lysine is preferably a lauroyl group. The ceramide or the derivative thereof is preferably ceramide type-2 or ceramide type-3. The vesicle can encapsulate an activeingredient. The vesicle can be contained in an external preparation for the skin.
