Abstract

Compositions, devices, methods, and kits are provided for determining the presence of topical compositions on surfaces, such as skin.

Claims

1. A device for determining the presence of a composition comprising a biologically active agent and a fluorescent chromophore on a surface, which comprises a light emitter, a light detector, an electronic evaluation system to determine the level of fluorescence of the fluorescent chromophore, and a display system, all contained in a housing that is hand-held.

2. The device of claim 1, wherein the light emitter emits visible light.

3. The device of claim 1 which is battery powered.

4. The device of claim 1, wherein the display system provides a visual indication of whether composition is present on the surface.

5. The device of claim 1, wherein the display system provides a visual indication of whether a sufficient amount of composition is present on the surface.

6. The device of claim 1, further comprising a shroud.

7. A kit comprising:

a) a composition comprising a topical agent and a fluorescent chromophore, and b) a device for determining the presence of the composition on a surface, which device comprises a light emitter, a light detector, an electronic evaluation system to determine the level of fluorescence of the fluorescent chromophore, and a display system, all contained in a housing that is hand-held.

8. The kit of claim 7, wherein the light emitter emits visible light.

9. The kit of claim 7, wherein the device is battery powered.

10. The kit of claim 7, wherein the display system provides a visual indication of whether composition is present on the surface.

11. The kit of claim 7, wherein the display system provides a visual indication of whether a sufficient amount of composition is present on the surface.

12. The kit of claim 7, wherein the device further comprises a shroud.
