A skin external preparation includes an oil-in-water emulsion composition. The emulsion composition contains first oil droplet particles having a minimum particle diameter of 200 nm or more and second oil droplet particles having an average particle diameter of 70 nm or less. The first oil droplet particles contain a first functional oil component, and the second oil droplet particles contain a second functional oil component. A method of producing the skin external preparation includes mixing a first emulsion containing the first oil droplet particles having a minimum particle diameter of 200 nm or more and a second emulsion containing the second oil droplet particles having an average particle diameter of 70 nm or less
