1. A multi-phase, fluid skincare composition comprising:
(a) at least one cream phase; and
(b) at least one gel phase;
wherein the at least one cream phase and the at least one gel phase are visually distinct phases that are packaged in physical contact;
wherein a viscosity ratio of a viscosity of the at least one cream phase to a viscosity of the at least one gel phase is from 1:3 to 3:1;
wherein the viscosity of the at least one cream phase is between 45 Pa·s and 55 Pa·s;
wherein the viscosity of the at least one gel phase is between 23 Pa·s and 31 Pa·s;
wherein the at least one cream phase and the at least one gel phase are present in the composition at a level such that a weight ratio of the at least one cream phase to the at least one gel phase is within the range of from 52:48 to 48:52;
wherein the at least one cream phase is in the form of a water-in-oil and/or silicone emulsion; and
wherein the viscosity is measured at 23° C. using a Brookfield RVDV-I Prime viscometer with a heliopath, a speed of 10 revolutions per minute (rpm) for a time of 30 seconds using a T Bar spindle.
