The invention discloses a lipstick and a preparation method thereof. A plurality of plant extracts are taken as raw materials; the plant extracts mainly include ethylhexyl palmitate, tribehenin, sorbitan stearate, palmitoyl oligopeptide, polyester-4, C12-15 alkyl benzoate, persea Americana butter, paraffin, polyethylene, beewax, copernicia cerifera wax, 1,2-hexanediol, phenoxyethanol, tocopheryl acetate, caprylyl glycol, sodium hyaluronate, wheatgerm oil, prunus amygdalus dulcis oil, castor seed oil and rosa damascena flower oil. The lipstick is developed aiming at the shortcomings of the existing lipsticks; the active ingredients of the plant extracts are combined with the four raw materials, namely ethylhexyl palmitate, tribehenin, sorbitan stearate and palmitoyl oligopeptide, to form lip enhancement factors, and therefore, the lipstick is capable of promoting the synthesis of the collagen and the glycosaminoglycan of lips and fading cheilogramma so that the lips are moister and better in moisture preserving ability, full and smooth, and clearer in outline.
