Fill the bath with enough water such that the QV Flare Up Bath Oil bottle can be submerged up to the marked "fill line". To ensure adequate dilution, the grey panel on the back of the bottle should blend with the cloudiness of the diluted bath solution while the black panel is still visible. If neither panel is visible, add more water to the bath until only the black panel is visible. Soak in diluted bath solution for 10-15 min. Gently pat skin dry.
