The Substance follows Elisabeth Sparkle (Demi Moore) as she is fired from her job as a workout star for her age.
Elisabeth watches a commercial for “The Substance,” a treatment to “become your better self” and make a “younger, hotter” version. She orders the treatment, injecting the fluid into her body.
A second body emerges: Sue (Margaret Qualley). The two must alternate consciousness each week, “respecting the balance.” However, Sue replaces Elisabeth and slowly stops giving Elisabeth control, causing Elisabeth’s body to deform.
I will stop here but it was one of the most shocking and interesting movies I’ve watched. The message of the movie is that aging is natural and searching for youth will only make you unhappy, a message that our generation needs.
