. In its classic form, a person or place is shown before using the product and then after: eyelashes before application of Tag Heuer Replica Watches mascara, eyelashes after application of mascara.

Has other makeup, a new hairstyle or clothing, a more pleasant expression, more dynamic action, or different lighting been added to the after segment? In other words, the critic asks, is the "if" necessary and sufficient to produce the promised "then"?
