Spraying perfume on your neck? Experts warn of health risks, including potential cancer

Spraying perfume directly onto the neck, a common practice for longevity, is now under scrutiny due to potential health risks, including links to thyroid disorders and even cancer. Research highlights that many perfumes contain substances like formaldehyde-releasers and phthalates, which act as endocrine disruptors.

One review published in 2025 in the journal 'Frontiers in Toxicology' has already analyzed the health risks associated with perfumes and other cosmetic products, which contain, for example, substances that release formaldehyde, phthalates and volatile organic compounds.

These chemicals can interfere with the body's natural hormone functions, potentially leading to issues such as infertility and respiratory problems. A key concern is the "fragrance" loophole, where manufacturers can legally hide thousands of chemicals under this single label, leaving consumers unaware of the exact ingredients.

These are endocrine disruptors, meaning they can essentially mimic or block the action of your hormones.

Experts emphasize that the neck is particularly vulnerable. Its skin is thin, and the area has a high blood flow, allowing fragrance chemicals to penetrate the bloodstream rapidly. This daily, long-term exposure is what currently concerns scientists most, as it could have cumulative effects on health over time.

The neck is one of the areas with the highest blood flow in the body, and the skin on the neck is also quite thin. This means that fragrances and chemicals can penetrate deeper and faster and directly enter the bloodstream.
