Faustina (1957), a Spanish film by José Luis Sáenz de Heredia.
It's a romantic comedy story based on Faust. An apprentice demon (Fernando Fernán Gómez) is sent to the mortal plane by an older and tired Mephistopheles, in order to fulfill a pact of youth requested by an older woman known as Faustina (María Félix). He presents himself in her home as any other business man, making her sign a contract before setting up all the stuff he needs for the transformation.
She's told to sit in front of the mirror, but the demon makes a mistake in his calculations and regresses her into a toddler. He clumsily handles her, places her in the closet, then repeats the ritual right, opening the door again to let out a 20 years old Faustina, whom he recognizes.
Turns out that many years back, they used to be lovers. In his youth, Mogón had commited suicide amid a war after making a promise to Faustina, and he ended up working in hell. So he's also technically stuck in age stasis.
The scene starts around minute 18 onwards.
