The spray cloud may be delivered in connection with applications of atomized (misted) sunless tanning sprays using a variety of spray systems. A formulation of the cosmetic or conditioning liquid may conduct and retain heat to allow a pleasantly warm spray to be received on the skin surface. The formula may come to temperature quickly and the heat may be retained even though a nozzle cooling effect inherently cools the spray as it leaves the nozzle. ## Claims ### Claim 1 A method for applying a heated skin treatment spray to coat a target surface, comprising: heating a heat retaining emulsifying wax; emitting a heat retaining skin treatment solution comprising the heat retaining emulsifying wax; atomizing the heat retaining skin treatment solution using an atomizing nozzle associated with a sprayer to create a spray cloud;
