The application provides a traditional Chinese medicine gel for treating stubborn skin color spots and a preparation method thereof, and the traditional Chinese medicine gel is prepared from the following raw materials in mass parts: aloe extract 25-30 parts, opuntia dillenii Haw extract 10-15 parts, safflower 5-10 parts, radix lithospermi 5-8 parts, herba portulacae 5-8 parts, purified water 60-65 parts, carbomer 1-5 parts, fish scale glue 5-8 parts, hydrogenated castor oil 100-110 parts, ethanol 120-140 parts and monoglyceride 4-10 parts. The prepared traditional Chinese medicine gel can clear heat and cool blood, remove blood stasis and remove spots, promote skin metabolism, repair damaged skin cells, and can treat stubborn skin color spots such as chloasma, melasma and age spots, and has no side effects.

The invention belongs to the technical field of chemical materials, and particularly relates to fucoxanthin-coated lipidosome as well as a preparation method and application thereof. The fucoxanthin-coated liposome provided by the invention comprises the following components in percentage by weight: 30-50% of water; 30 to 50 percent of polyhydric alcohol; 5-10% of an antioxidant; 1-5% of a solubilizer; 1% to 5% of isosorbide dimethyl ether; 1-5% of lecithin; 1-5% of a dispersant; 0.1-1% of a stabilizer; and the fucoxanthin accounts for 0.05 to 5 percent. The fucoxanthin liposome has the advantages that by optimizing the components of the fucoxanthin liposome, the permeability of the fucoxanthin on the skin surface is enhanced, and the skin is prevented from being stained; meanwhile, the fucoxanthin-coated liposome provided by the invention has very good water solution solubility, can be directly added into a water phase, is small in skin irritation and high in stability, and has a wide practical application value.

A lip liner including a solvent configured to evaporate substantially independently of a user's skin, a film-forming agent dissolved in the solvent and configured to form a uniform film over the user's skin as the solvent evaporates, and one or more colorants dissolved in the solvent and configured to stain the user's skin.
