Actors may deliver impassioned speeches about achieving their “childhood dreams,” but we don’t often hear about how those sculpting wounds with clay and bubbling skin with latex are fulfilling their lifelong fantasies.

“Teenager treats” is how Pierre Olivier Persin, the special effects designer nominated for an Oscar for makeup and hairstyling for “The Substance,” described his work on the film, which involved two full-body prosthetics and countless other pieces and puppets. Mike Marino, the makeup designer for Sebastian Stan in “A Different Man,” nominated in the same category, described his childhood bedroom as a sort of cabinet of curiosities, filled with “jars of experiments and screaming Siamese twins.”

It’s a particularly exciting year for makeup and hairstyling nominees: buckets of blood and pus-filled injections in “The Substance”; face tumors sloughing off like jelly in “A Different Man”; green witches and blue horses in “Wicked”; a vampire shriveling away in “Nosferatu”; and a menacing drug lord created with facial prosthetics in “Emilia Pérez.”

While in years past the category has sometimes leaned toward honoring the subtle transformations of delicately coifed period hairstyles, these nominees reflect a year that relied heavily on the use of makeup to create practical special effects.

Once upon a time, most special effects were achieved with makeup. Think “An American Werewolf in London” (1981), “The Fly” (1986), “Beetlejuice” (1988): All the various monsters, mutations and marvels in these films were largely created with latex, foam and human hands. Then, in the early 2000s, studios became more reliant on computers to digitally generate these effects.
