1. A method of flattening a perfume-release profile from a heated-wick perfume composition-dispensing device comprising two or more perfume modules comprising at least a first and second reservoir containing a perfume composition, and at least a first and second wick in fluid communication with the perfume composition, comprising:
- a1) applying heat to the first wick to achieve a wick temperature sufficient to increase the rate of volatilization of at least one component of the perfume composition;
b1) reducing the heat applied to the first wick to achieve a wick temperature sufficient to decrease the rate of volatilization of the at least one component of the perfume composition;
c1) maintaining the reduced heat for a time sufficient to allow for back-flow of at least one component of the perfume composition, the time being greater than 15 minutes to about 48 hours;
a2) automatically applying heat to the second wick to increase volatilization of at least one component of the second perfume composition;
b2) reducing the heat applied to the second wick to a temperature sufficient to decrease volatilization of the at least one component of the second perfume composition;
c2) maintaining the reduced heat applied to the second wick for a time sufficient to allow for back-flow of at least one component of the second perfume composition the time being greater than 15 minutes to about 48 hours;
repeating a1); and
repeating a2).

Abstract
Systems, devices, methods, and compositions that improve the scent perception for a user. Improved scent perception is achieved by presenting alternating scents and by varying levels of output of scents, as well as by minimizing device clogging, thereby improving evaporation profiles.

20. A method of flattening a perfume-release profile from a heated-wick perfume composition-dispensing device comprising:
-
a) applying heat to the wick to achieve a wick temperature sufficient to increase the rate of volatilization of at least one component of the perfume composition, wherein the increased volatilization occurs for a period of from 17 minutes to about 72 minutes; b) reducing the heat to achieve a wick temperature sufficient to decrease the rate of volatilization of the at least one component of the perfume composition; c) maintaining the reduced heat for a time sufficient to allow for back-flow of at least one component of the perfume composition, the time being 17 minutes to 72 minutes; and repeating a).
