It's Punky Brewster

Pretty Ugly (1x5)

Air date: Sep 28, 1985

Punky talks Margaux into attending dweeb Avery Bigelow's dad's party so she can win a photo job for Henry. In primping Margaux up, Glomer prepares a facial that turns Margaux's face into a glomley face. Punky has to disguise herself as Margaux until the facial wears off.
