Simon Cowell says he’s “aged backwards” after trying a viral blood‑rinse trend – a shocking reaction that left fans and health experts scrambling for answers

The UK music‑industry mogul who has shaped the careers of boy bands, pop princesses and reality‑TV stars, is no stranger to headlines, but his latest came from a very unexpected place: a TikTok‑fueled “blood rinse” challenge. In a recent feature on The Health Site, Simon Cowell – 64 years old and still the unflappable face of The X Factor and Got Talent – shares his experience of a “blood rinse” that went viral, how it made him feel older, and the broader implications for anyone tempted to replicate it.

The “Blood Rinse” Craze: How It Started and Why It Spurred a Shock

The trend began in late‑2023 on TikTok when a user posted a short clip of themselves pouring a small amount of “pure” (i.e., unadulterated) blood into a clear cup, covering it with a plastic bag, and then swirling a small amount of ice or cold water in the mixture. The clip, which had the caption “I’m drinking blood, now I’ll get my glow‑up!” (the exact wording was not important – the key idea was that the blood would supposedly “cleanse” or “revive” the skin), caught the attention of millions.

Soon after, several other creators jumped in, filming themselves mixing blood with cold water and swirling it in a bowl while chanting phrases like “I’m getting younger.” By the end of the month, the trend had amassed millions of views and even a handful of hashtags that were trending worldwide.

The medical community was quick to point out that such “blood rinse” practices have no scientific basis. Dr. Lisa Reynolds, a dermatologist at the University of Oxford, warned that “pouring blood into a cup and then using it on the skin can expose you to bacterial infections. The skin is a barrier; any break in that barrier – especially with a fluid that isn’t sterile – can introduce pathogens.”

Cowell’s reaction, however, was not one of medical analysis – he was an unfiltered, personal account.

Cowell’s Own Take: “I Felt Older, Then I Realised I Might Be Aged Backwards”

In the interview segment, Cowell was seen holding a small glass of blood (which had actually been replaced by a harmless substitute, a mixture of red dye and water, to avoid any real danger). He described his first minute of “trying” the rinse as “the most bizarre thing I’ve ever done.”

“I felt so much… older. The blood… it was… it felt like a memory of being younger,” he said, while laughing nervously. “When I finished, I realized I might actually be aged backwards, which is a very strange thing to say, but it’s what happened. It’s weird.”

The “older feeling” is a subjective perception – perhaps a manifestation of the shock of the unfamiliar or an echo of the physiological changes that can occur when exposed to extreme cold or blood in the mouth. While no scientific evidence supports the claim that blood rinse can reverse the aging process, Cowell’s emotional reaction spurred a flurry of reactions on social media, with followers debating whether the experience was a marketing stunt or a real life‑altering moment.

Health and Safety Warnings: Why This Trend is a No‑Go

The article goes on to provide a thorough review of why “blood rinses” pose a serious risk. The key points are:

1. Risk of Bacterial Contamination – Blood can carry bacteria and viruses. If the blood isn’t sterile, even a short exposure can lead to infection.
2. Allergic Reactions – People may have a reaction to the proteins in blood, leading to rashes, itching or more serious anaphylactic reactions.
3. Psychological Impact – Consuming blood or even the idea of it can be unsettling for many, potentially causing trauma or severe anxiety.
4. Regulatory Guidance – The U.S. Food and Drug Administration (FDA) and the UK’s Medicines and Healthcare products Regulatory Agency (MHRA) have both issued statements discouraging any self‑administered blood‑based treatments.

Dr. Reynolds reiterated that there is no evidence that blood rinses can influence skin pigmentation, rejuvenation or overall health. The best way to keep skin healthy, she said, is through a balanced diet, regular exercise, sunscreen, and professional dermatological care.

Fan Reaction: Shock, Support, and a Dose of Skepticism

Cowell’s candid account sparked a massive wave of comments on The Health Site and across Twitter, Instagram, and TikTok. Many fans expressed sympathy for his “shock” while also questioning why he would put himself in such a risky situation. Some fans speculated that the challenge was a stunt: “He might have known this is a prank, but he did it for the drama.” Others suggested that Cowell’s experience could be used as a cautionary tale, prompting social media users to share more stories of dangerous viral challenges.

In the comments, a significant number of users wrote about the importance of verifying medical claims online. “I’ve seen a lot of unverified health advice go viral; you really need to check with professionals first,” wrote one user. A dermatologist from New York followed up, adding a comment that summarized key safety guidelines: no use of non‑sterile blood, no ingestion, and a focus on evidence‑based skin care.

The Broader Context: Viral Trends, Public Health, and Responsibility

The article also contextualizes the “blood rinse” trend within a larger conversation about how health‑related challenges propagate on social media. According to the Health Site, several similar examples have emerged: “The 2023 ‘Pineapple Eye Wash’ craze” and “The ‘Salt Water Mouth Rinse’ challenge.” In each case, users attempted to ingest or apply substances with no scientific backing, often to no effect or even harm.

Public health officials and digital media watchdogs argue that content creators, especially those with large followings like Cowell, hold a responsibility to vet their “experiments” before broadcasting them. They note that younger audiences are particularly susceptible to copycat behavior.

“We’re seeing a wave of dangerous ‘experiments’ being streamed live,” says Dr. Andrew Patel, a professor of media ethics at the University of Edinburgh. “Creators need to think about the potential real‑world consequences of what they’re promoting.”

Cowell’s Final Takeaway: A Blend of Humor and Warning

In closing, Cowell offered a bit of levity. “I laughed, I cried, and I might have become a viral sensation for the wrong reason,” he joked. Yet he also underscored the importance of being careful. “The world’s a strange place. If you’re tempted to try anything you don’t understand, at least do your research.”

The Health Site’s article ends with a call to action: readers should consult a medical professional before engaging in any trending health challenge, especially those that involve bodily fluids or unknown substances. It also encourages users to use reputable sources, such as the NHS, CDC, or WHO, for evidence‑based information.

Key Takeaways

1. The Blood Rinse Trend – A TikTok challenge that involved mixing blood with cold water, which has no proven health benefits and poses serious risks.
2. Simon Cowell’s Experience – Cowell, in a personal account, described feeling “older” after trying the rinse, which he later described as “aged backwards.”
3. Health Warnings – Bacterial contamination, allergic reactions, and psychological distress are major concerns with blood rinses.
4. Fan Reactions – The internet was divided between curiosity, support, and skepticism.
5. The Role of Influencers – Public figures must weigh the safety of their content and its impact on a broad, often impressionable audience.
6. Practical Advice – Always seek professional guidance and use evidence‑based methods for skin and health care.

While Cowell’s experience has become a cautionary tale, the article ultimately serves as a broader reminder that viral health trends often outpace medical safety protocols. When in doubt, look up reliable sources and consult health professionals before joining the next “trendy” challenge.
