At what point in a facial should the formal skin analysis be performed?

Makeup, sunscreen, and surface oil hide the true condition of the skin, so analysis is performed after cleansing, with a magnifying lamp and eye pads or goggles to protect the client's eyes from the light. Analyzing before cleansing gives a false reading. Waiting until after the mask or until a later visit means the treatment plan was never based on the skin's actual condition.
