Cosmetic products carry cancer risk warning: Expert explains risks of hair straighteners and permanent nail polish

Medical Oncology Specialist Dr. Burçin Çakan Demirel has cautioned that while not all cosmetic products are dangerous, certain chemicals in some items can pose health risks with prolonged and intensive use. She specifically highlighted concerns regarding chemical hair straighteners, products with a risk of benzene formation, and permanent nail polishes cured under UV light.

We need to be careful about chemical hair straighteners, products that carry a risk of benzene formation, and permanent nail polishes cured with UV light. Product content and reliability are of great importance when choosing cosmetics.

Dr. Demirel cited a large-scale study involving approximately 34,000 individuals, which indicated a potential increase in uterine cancer risk associated with frequent use of chemical hair straighteners. Formaldehyde and similar chemicals are thought to be contributing factors, emphasizing the need for informed use of these products despite the exact causative agent not being fully identified.

In a comprehensive study involving approximately 34,000 people, frequent use of chemical hair straighteners was shown to increase the risk of uterine cancer. Some chemicals like formaldehyde are thought to play a role in this risk.

The expert also pointed out that some cosmetic ingredients can transform into benzene if stored improperly, especially under high temperatures. Products containing benzoyl peroxide are particularly susceptible. Additionally, chemicals added to enhance the water resistance of makeup may have adverse health effects with long-term use.

Even if benzene is not directly present in some cosmetic products, some ingredients can convert to benzene under inappropriate storage conditions.

Regarding permanent nail polishes, Dr. Demirel noted that the primary risk stems from prolonged exposure to UV light during the curing process, suggesting protective measures can mitigate this. She also mentioned historical concerns about talc powders due to potential asbestos contamination during manufacturing. The most crucial advice, however, is to avoid counterfeit and unregulated cosmetic products, which may contain harmful chemicals to extend shelf life. Consumers should always purchase cosmetics from reputable brands and trusted retailers.

The most important point is to stay away from counterfeit and underground cosmetic products. Harmful chemicals may be used in these products to ensure a longer shelf life.
