In the serie of italian erotic short movies from 1995 called "Erotic tales. Volume III", the second episode "Caramelle" is about a woman using magic candies from a sorcerer to grow younger, and eventually overdosing.https://www.imdb.com/_title_/tt0112630/plotsummary?ref_=tt_ov_pl
"Anna is not so very young any more, but still a voluptuous woman and full of desire. Unlike her husband, who prefers to watch television instead of making love to his wife. Diets and aerobics fail to revive his sexual interest, and Anna turns to a fortune-teller for help. Unfortunately, the love potions also have dissatisfying side-effects and surprising results. Finally, a proper solution is found in some magic sweets: each sweet will make Anna seven years younger. Which might be rather tricky for a compulsive eater."
It seem Anna is shown to have a "sweeth tooth" throughout the movie. Near the end, the middle aged woman keep eating some more of the candies (which have a slightly delayed effect) before and after making love with her husband making nude photograph of her in their appartment. She seem to look younger by use of make up, or removal of the make up previously used to make her look older (no CGI here).
Before departing, the man place a few more candies on her nude back (we can't see her face, but it's obviously the body of a much younger and sexier woman). Later, she get up to take a shower, glimpse of her body being shown, eating the remaining candies. Meanwhile, a concierge character finish repairing her faulty fauncet that had been shown several times in the movie. He find one of the red candy, and keep it. When he leave, he pass the opened bathroom door and leer at her nude youthful body behind the shower door for a moment before leaving.
Next shot, the feets of a little girl can be seen leaving the shower, then we see her look up and discover she's regressed down to a little child, her hand going to her face in horror. The scene is halas a bit short.
Then we see her going down the stair in her oversized, iconic full red dress and heels. She cross path with the concierge who, upon seeing the little girl in tears, offer him his candy. She's seen hesitating, visibly torn, then relent and eat it. As she make a few more steps, she suddenly turn back to the man with a laugh as weird colors fill the room, then under his shocked eyes the magic regress her into nothingness. Quite litteraly, with a "poof" AR leaving only her red heels and the candy wrapper falling on the ground. The End.
The short movie can apparently only be found under the russian version "Эротические истории. Том 3. 2. Леденцы (Caramelle) ", which use the extremely annoying system of russian voice OVER the italian ones, but well, better than nothing :
The AR events roughly start to really happen 'round 25:00 :http://video._meta_.ua/4396888.video?playlist_id=17305
