Abstract
Compositions, devices, and methods related to determining adequacy of the application of a sunscreen composition on human skin are disclosed. A disclosed sunscreen composition includes a sunscreen agent and a fluorescent agent, which, when excited by an ultraviolet light having a compatible wavelength, fluoresces in visible light. A method for determining whether the sunscreen composition has adequately applied on human skin is disclosed. A disclosed device generates an ultraviolet light having a compatible wavelength and is portable.
Claims30
A sunscreen composition for application to human skin, comprising:
- a sunscreen agent selected from the group consisting of UVA sunscreen agent, UVB sunscreen agent, UVA-UVB sunscreen agent, and mixture thereof;
- and
- a fluorescent agent in an effective amount;
- wherein the fluorescent agent emits a visible light when irradiated with an ultraviolet light having a compatible wavelength.
A method for determining adequacy of an application on skin of a sunscreen composition comprising (i) a sunscreen agent selected from the group consisting of UVA sunscreen agent, UVB sunscreen agent, UVA-UVB sunscreen agent, and mixture thereof, and (ii) a fluorescent agent in an effective amount, wherein the fluorescent agent emits a visible light of a predetermined color, when irradiated with an ultraviolet light having a compatible wavelength, the method comprising:
- manually applying a recommended amount of the sunscreen composition on an area of the skin;
- imparting, using a UV lamp, the ultraviolet light on the area of the skin;
- and
- visually inspecting, during the imparting the ultraviolet light, the area of the skin to determine if the predetermined color does not appear in any subregion of the area of the skin.
A portable device comprising:
- a container containing a sunscreen composition, the sunscreen composition comprising (i) a sunscreen agent selected from the group consisting of UVA sunscreen agent, UVB sunscreen agent, UVA-UVB sunscreen agent, and mixture thereof, and (ii) a fluorescent agent;
- and
- a UV lamp attached to the container;
- and
- wherein the UV lamp, when powered on, emits an ultraviolet light having a compatible wavelength;
- wherein the sunscreen composition emits a visible light when irradiated with the ultraviolet light emitted by the UV lamp.
