Disclosed is a two-dosage-form essence including oil gel and hydrogel. The oil gel and the hydrogel are mixed according to a preset ratio during use. The oil gel includes the following components in parts by weight: 0.1-6 parts of active ingredient; 15-35 parts of polyol; 0.1-1 part of SODIUM SURFACTIN; 10-70 parts of oil; and 1-10 parts of water. The two-dosage-form essence according to the present application is mixed according to a preset ratio during use, and the oil gel and the hydrogel have a transparent appearance and good stability. Also disclosed is a method for preparing a two-dosage-form essence. The oil gel and the hydrogel are prepared separately. The oil gel is prepared by a D-phase emulsification method. A low amount of emulsifier can emulsify an oil phase with a high oil content.

The disclosure provides a peptide microparticle structure that can easily penetrate into the bottom layer of the skin. The peptide microparticle structure is composed, from inside to outside, of a main core, a first lipid layer, an active ingredient layer, and a second lipid layer. The main core is disposed at the center of the peptide microparticle structure, and the outer part of the main core is completely covered by the first lipid layer. The outermost layer of the peptide microparticle structure is the second lipid layer, and between the first lipid layer and the second lipid layer is the active ingredient layer.
