A stable, oil-in-water (O-W) emulsion-based sunscreen composition having at least one water-insoluble, organic UV-absorber having a water-solubility of much less than 0.1% by weight, contained in the oil phase of the sunscreen emulsion, comprising i) zinc oxide (ZnO) particles having a surface free of any prior coating of any inorganic oxide and hydrophobic material, remaining dispersed in the water phase of the sunscreen emulsion; ii) at least one non- or low-foaming, non-cationic, hydrophilic polymer, capable of dispersing or deflocculating the ZnO particles but incapable of thickening an aqueous composition to a viscosity of greater than 100 cps at 25° C., wherein the viscosity is measured using a Brookfield viscometer operated at 10 rpm for 15 seconds, when the polymer is added at an amount of 1%, based on the total weight of the polymer and water in the aqueous composition; iii) at least one phenolic polymer, capable of functioning as a dispersing or deflocculating agent for particulate material(s), and adsorbing at an oil-water interface; and v) a buffering agent for the water phase of the sunscreen emulsion.

The invention discloses sunscreen lotion containing natural plant sunscreen components and a preparation method thereof, which comprises A component, B component and de-ionized water; wherein, the A component comprises 5 percent to 10 percent of whiteruss, 3 percent to 8 percent of octodecyl alcohol, 3.5 percent to 6 percent of stearic acid, 0.6 percent to 1.2 percent of sodium lauryl sulfate and 0.1 percent to 0.2 percent of nipagin methyl ester; the B component comprises 6 percent to 9 percent of glycerin, 1 percent to 3 percent of Chinese traditional medicine ingredients, 0.3 percent to 0.5 percent of essence and 0.1 percent to 0.2 percent of nipagine propyl ester; the Chinese traditional medicine ingredients per gram is composed of 0.15 gram to 0.30 gram of flos sophora, 0.50 gram to 0.75 gram of honeysuckle and 0.10 gram to 0.20 gram of peony. When the sunscreen cream is prepared, the Chinese traditional medicine is firstly prepared. Secondly, the A and the B components are respectively heated to about 80 DEG C to be melted, the A component is added into the B component along with stirring, and then the de-ionized water is added into the mixture. The fast stirring can not stop until the mixture is emulsified completely, and then the mixture is cooled to obtain the sunscreen lotion containing natural plant sunscreen components. The invention has broad-spectrum function to UV-A and UV-B rays and compensates the deficiency of a single component, and has favorable effect on absorbing ultraviolet radiation.

A method for calculating a rate of UV radiation absorbed by a user's skin including: capturing image data of an area of the user's skin; determining a skin tone of the user's skin based on the captured image data; calculating a rate of UV radiation absorption for the determined skin tone; measuring an amount of UV radiation exposed to the user's skin; and calculating a rate of UV radiation that would be absorbed by the user's skin based on the user's skin tone and the amount of UV radiation exposed to the user's skin. The method can further comprise calculating an amount of time that the user can be exposed to the amount of UV radiation exposed to the user's skin based on predetermined criteria. The predetermined criteria can at least include an SPF level of sunscreen applied to the user's skin.
