Does Milk of Magnesia Stop Sweating? What to Know About the Beauty Hack From Bachelor in Paradise

Kelsey Weier of BIP says it works, so we took it to dermatologists for their thoughts.

The return of Bachelor in Paradise, a cherished reality television series, ignited waves of excitement as it graced the screens once again on a Monday night. This resurgence marked a triumphant comeback following an extended hiatus enforced by the global pandemic. As the series resumed its operations, a cast of eager participants embarked on a captivating journey, set against the backdrop of the radiant Mexican landscape, in their quest to forge deep and meaningful romantic connections.

In this constellation of sun-kissed and lovelorn contestants, one figure emerged as a focal point of intrigue and determination – Kelsey Weier. She captivated attention with her unyielding resolve to maintain her meticulously applied makeup, defying the sweltering conditions that enveloped the Playa Escondida resort upon her arrival. Opening up to bartender Wells Adams, Weier shared a unique concern that she faced: her propensity to experience copious amounts of perspiration. In response to this challenge, she adopted a rather unconventional solution – the application of milk of magnesia to her facial skin. This intriguing beauty regimen, inspired by the counsel of a professional makeup artist, sparked conversations and curiosity among the show’s viewers and beyond.

However, the question that looms large is the nature and efficacy of milk of magnesia in the realm of skincare. Typically associated with alleviating digestive discomforts such as constipation, heartburn, and indigestion, this liquid medication finds its cornerstone in magnesium hydroxide, a potent ingredient renowned for its qualities as a saline laxative, adept at facilitating smooth and unobstructed bowel movements. Shedding light on the underlying mechanism, Dr. Gary Goldenberg, a prominent dermatologist affiliated with Goldenberg Dermatology in New York City, elucidates the inherent capacity of milk of magnesia to draw fluids into the intestinal tract, thereby facilitating a seamless digestive process.

The crux of the matter centers around the uncharted territory of whether milk of magnesia possesses the capability to effectively suppress excessive sweating. Notably, the product’s packaging refrains from endorsing its topical application. Nevertheless, dermatological experts delve into the potential viability of this unconventional approach. Dr. Goldenberg postulates that applying milk of magnesia topically could potentially lead to the absorption of moisture, including sweat, thereby curbing the propensity for profuse sweating. However, a decisive consensus on whether this method can entirely halt perspiration remains an arena of spirited debate.

Expanding upon the intriguing world of magnesium-based compounds, their influence extends to the realm of natural deodorants. Dr. Joshua Zeichner, a prominent figure in the field of dermatology as the director of cosmetic and clinical research at Mount Sinai Hospital, draws attention to milk of magnesia’s inherent antimicrobial properties. These attributes equip it to effectively reduce the presence of odor-causing bacteria on the skin’s surface, thereby presenting a promising avenue for odor control.

Dr. Zeichner further unravels the intricate dynamics of sweat itself – conventionally devoid of any discernible odor. Yet, when subjected to the metabolic processes of bacteria residing on the skin, an unwelcome malodorous transformation ensues. Hence, the notion of leveraging milk of magnesia as an instrument to curtail these olfactory transformations gains prominence, particularly in regions susceptible to elevated sweat accumulation, such as the underarms.

In summarizing the discourse, the revival of Bachelor in Paradise heralded a cascade of enthusiasm as participants embarked on their quest for love, framed against the captivating backdrop of the Mexican sun. Kelsey Weier’s audacious utilization of milk of magnesia to safeguard her makeup became a catalyst for intrigue, triggering contemplation and discourse. While its conventional role remains tethered to addressing digestive concerns, the magnesium-based attributes of milk of magnesia beckon enticing prospects for managing sweat-related challenges and body odor. Nonetheless, the efficacy of this approach remains an ongoing subject of exploration, beckoning the confluence of rigorous scientific investigation and individual experimentation.

As the spotlight shifts, the spotlight turns towards a pivotal question: Can the application of milk of magnesia on the skin be considered a viable and prudent beauty hack? The collective sentiment among dermatologists appears to lean towards reservations regarding this unconventional endeavor. Dr. Joshua Zeichner, a leading authority in the field, stands firm in his stance – this technique isn’t one he endorses. His sentiments are unequivocal: “I do not recommend using it.” Dr. Zeichner proceeds to expound that the practicality of applying milk of magnesia onto the skin isn’t a seamless affair. It necessitates a process resembling the application of a mask – the substance must dry on the skin before being washed off. However, this approach directly clashes with the very intention of employing milk of magnesia to impede perspiration.

Venturing into the chemical realm, milk of magnesia reveals itself as possessing an alkaline pH composition. Dr. Zeichner issues a cautionary note here, warning that this alkaline nature might disrupt the outer layer of the skin, potentially leading to undesirable consequences such as dryness and irritation.

The potential ramifications of milk of magnesia’s topical use extend beyond pH considerations. A conceivable consequence is the obstruction of pores, a scenario that could serve as a catalyst for acne breakouts. Furthermore, the specter of triggering allergic reactions looms, as cautioned by Dr. Gary Goldenberg.

Delving into the practicality of integrating makeup application with milk of magnesia underscores another complexity. Dr. Goldenberg introduces a compelling argument – the liquid consistency of milk of magnesia renders the seamless overlay of makeup a challenging endeavor. The compatibility of these two substances raises questions about the feasibility of their harmonious coexistence.

In light of these multifaceted concerns, the counsel from dermatological luminaries is unequivocal: exercising caution and prudence while shying away from this particular beauty hack is prudent. The potential pitfalls, spanning from disturbances in the skin’s pH equilibrium to the potential for pore-clogging and allergic reactions, outweigh the perceived advantages. While venturing into innovative beauty routines is often applauded, this instance underscores an equilibrium tilting towards risk rather than reward. Therefore, a consensus emerges among dermatologists – abstaining from experimenting with this approach within the confines of one’s home is the course of wisdom. The pragmatic path involves prioritizing established skincare methodologies, fortified by scientific validation, ensuring the health and vitality of one’s precious skin.
