Thats right, I am a beauty fanatic follows the autobiographical explorations of manga artist Mankitsu, a self-proclaimed beauty obsessive with over two decades of experience in pursuit of flawless skin and eternal youth. The narrative is driven by her unwavering belief that while people may betray you, beauty never does, leading her to test an extensive and often extreme range of cosmetic methods. The setting shifts between her everyday life in Japan, local drugstores, high-end cosmetic counters, and the clinical environments of medical aesthetic practices. The central character is the author herself, drawn as a relatable yet comically intense figure whose curiosity knows no bounds, accompanied occasionally by her skeptical partner, Oyana-san, who reacts with horror to her latest experiments. The storyline is structured as a series of real-life experiments rather than a fictional plot, chronicling her successes and hilarious failures. One notable arc follows her quest for affordable skincare, where she identifies drugstore holy grail items like Melano CC for full-body application. Another major arc details her decision to undergo blepharoplasty, an eyelid lift, which she describes as the most powerful anti-aging method of her life. The series also covers her deep dives into unconventional territory, such as using laundry bleach in her bath as a final resort for skin peeling, her struggles with hormonal acne and perimenopausal skin dullness, and her fixation on achieving a slim under-chin area to make her entire body appear thinner. The overarching narrative is not about reaching a final destination of perfection, but about the obsessive, often absurd, and deeply human journey of self-improvement and the maintenance of self-esteem through external care.
