In Short

This story follows an advertising executive tasked with launching a new lipstick, only to have his campaign hijacked by a seductive, unauthorized cosmetic line called "Atummyc Afterbath Dusting Powder." Containing a mysterious, radioactive ingredient, the product becomes an overnight sensation, granting users a flawless, glowing complexion. As the company rushes to expand the line into everything from shampoo to men’s toiletries, a disturbing medical side effect emerges, forcing the team to confront a reality that defies biological law and threatens to unravel the entire industry.

The Story

The protagonist, a product engineer and ad man, is hired by Elaine Templeton, Inc. to manufacture demand for a new, "kiss-proof" lipstick. While he navigates the office politics of the massive firm, he is waylaid by Dolores Donet, a manipulative and charming department head. She maneuvers him into signing a document he assumes is an administrative chore, which actually authorizes the launch of her pet project: a dusting powder laced with "Atummion," a byproduct of fission experiments.

The powder becomes a runaway success. Its primary allure, beyond the clever branding, is that it legitimately improves the user’s skin, erasing blemishes and providing a radiant, healthy glow. When the company realizes the public’s fervor, they pivot entirely, infusing the magic ingredient into thirty-eight different products. The protagonist, initially relieved that this unexpected hit covers for the lackluster performance of his lipstick campaign, soon encounters a horrifying development.

Dolores, who is unmarried, reveals to the inner circle that she is pregnant. Initially, the executives dismiss this as a personal mishap, but the mystery deepens when laboratory guinea pigs, strictly segregated by sex, begin to produce offspring. When the lab reports that even the male test subjects are somehow bearing young, the true nature of Atummion is revealed. It is not merely a cosmetic aid; it is a profound, biological catalyst that induces reproduction across the board. The story culminates in a surreal, gruesome realization for the protagonist: as he observes his own glowing, perfect skin, he realizes he, too, has been a regular user of the contaminated products. The nightmare is not just a corporate scandal, but a biological one that has already taken root within him and his colleagues.

How It Unfolds

The assignment begins The narrator settles into his office at a massive cosmetics firm, tasked with building a marketing strategy for a new, standard-issue lipstick. He is forced to endure a constant stream of pitches from ambitious department heads until he meets Dolores, who charms him into backing her strange "Atummyc" powder.

The accidental launch After unknowingly signing the authorization for the powder, the narrator discovers it has gone to market without his approval. He decides to stay the course, hoping the product might perform well enough to save his professional reputation.

The miracle product Sales explode as customers experience the powder’s genuine ability to clear skin and beautify. The company, sensing a gold mine, quickly reformulates its entire catalog to include the addictive ingredient, Atummion.

The biological crisis The mood shifts when the lab reports impossible results from animal testing. As the company faces scrutiny from the Atomic Energy Commission and federal regulators, the unsettling truth about the ingredient’s reproductive effects comes to light.

The final discovery The protagonist realizes that the testing was not tampered with, as he had suspected. In a final, chilling sequence, he discovers that the "atomic glow" he and his colleagues have been admiring is the mark of a transformation that leaves no one untouched.

The People

The narrator is a cynical, ambitious ad man who prioritizes professional survival above all else. He is easily manipulated by his own ego and his desire to find a "miracle" product that will secure his career. He is the lens through which we see the vanity of the industry, and he ultimately pays the price for his lack of oversight.

Dolores Donet is the catalyst for the disaster. She is a cunning, "fun-loving" social climber who uses her beauty and familial status within the company to push her dangerous agenda. She is the first to experience the product's side effects, yet she remains a cold, calculated actor who tries to manage the fallout only when her own secret becomes impossible to hide.

Madame Elaine Templeton is the ruthless head of the firm. Driven entirely by profit and the desire for market dominance, she treats the product’s danger as an inconvenience to be managed by lawyers and cover-ups. She represents the absolute indifference of a corporate machine that values brand loyalty over human health.

In Its Own Voice

The remarkable thing about Atummyc Afterbath Dusting Powder was that it gave you that lovely, radiant, atomic look--just the way the advertisements said it would.

What It's Really About

At its core, the book is a dark satire of consumerism and the blind faith we place in industry. It argues that modern marketing creates a dangerous feedback loop: companies don't just sell products; they sell manufactured desires, and in this case, a literal, chemical transformation. The "Atummion" acts as a metaphor for the toxic side effects of progress—the way we prioritize immediate, visible results over long-term safety. By linking beauty standards to a biological, quasi-radioactive mechanism, the story questions how far we are willing to go to achieve the "radiant" ideal and suggests that the drive for perfection, when left unchecked by ethics, ultimately leads to a loss of humanity.

Why Read It Today

Readers who enjoy the sharp, cynical tone of mid-century science fiction will find this a compelling, if unsettling, read. It captures a distinct moment in the 1950s when the public’s obsession with "atomic" power was both a source of wonder and a persistent, underlying anxiety. The prose is fast-paced and lean, reflecting the frantic energy of the advertising world.

However, modern readers should be prepared for the period-specific attitudes regarding gender and work. The narrator’s casual dismissal of his female colleagues and the stereotypical portrayal of "the Old Hag" are products of their time and may feel grating to contemporary sensibilities. The story is quite brief, functioning more like a sharp, punchy short story than a sprawling novel, which makes it an easy read in one sitting. What lingers after finishing is the visceral, body-horror twist in the final pages—a genuinely creepy reminder of how the pursuit of vanity can have unforeseen, life-altering consequences. It is a cautionary tale that feels surprisingly relevant in an age where the line between technology, beauty, and health continues to blur.
