1. A surgical skin preparation device for applying an antiseptic composition to skin of a patient, comprising:
an applicator arranged at a distal end of the device configured to absorb the antiseptic composition, the applicator comprising a top surface and a bottom surface, the bottom surface defining the distal most end of the device and configured to apply the antiseptic composition to the skin of the patient; and
an indicator comprising:
a first layer comprising a first material configured to wick the antiseptic composition, wherein the first material is opaque in a first state and is transparent or translucent in a second state; and
a second layer comprising a non-wettable material, the second layer comprising at least one indicia that is visible to a user when the first layer is in the second state,
wherein the first layer is configured to progressively change from the first state to the second state as the antiseptic composition is wicked from a first end of the first layer to a second end of the first layer, with the first layer becoming more wet as the composition is wicked from the first end to the second end, allowing progressive exposure of the second layer,
wherein the first layer is in the first state when the antiseptic composition has not been wicked along the first layer, and the first layer is in the second state when the antiseptic composition has been wicked along more than about 50% of the first layer, and
wherein the first material is a wettable material having a surface with a water contact angle of 75 degrees or less and the first material is configured such that the antiseptic composition is wicked across more than about 50% of the first layer about 30 seconds following initial exposure of the first material to the antiseptic composition,
wherein the indicator is arranged on the top surface of the applicator and the second layer of the indicator is arranged between the top surface of the applicator and the first layer of the indicator.
