You may be well-versed in all the myriad ways in which cosmetics enhance your appearance. But are you aware of how cosmetics can contain ingredients that negatively impact your health? For breast cancer awareness month, we're highlighting some of the ingredients contained within cosmetics that can have adverse effects on our bodies. We'll also recommend some products free of those troubling ingredients— so that you can enjoy using beauty products without worry. 

 

Ingredients to Avoid

When it comes to breast cancer, many scientific studies have investigated the link between certain cosmetic ingredients in relation to breast cancer risk. Generally, any ingredients which have the potential to disrupt the hormones in our bodies, including testosterone and oestrogen, can increase the risk of developing breast cancer. Ingredients that are classified as carcinogens, a substance capable of causing cancer in living tissue, must also be avoided. 

 

Aluminium is used in antiperspirant products to block sweating. By preventing sweat from leaving the body, it reduces the bacteria growth of sweaty armpits, reducing body odour. However, this metal has been shown to affect oestrogen and some suggest that it could increase the risk of breast cancer. Yet the studies don't all yield a conclusive answer. Additional studies in this area are pending.

 

Cadmium is a metal that is most often used in batteries, coatings and plating, semi-conductors, and as a stabilizer for plastics. However, it can be a contaminant in some colour cosmetics and face paints marketed to kids. Cadmium has been shown to demonstrate oestrogen-like activity, which is known to increase breast cancer risk. Other metals such as nickel, chromium, zinc, lead and mercury have been shown to have similar estrogen-like effects.

 

Polyacrylamide (acrylamide). Polyacrylamide is a stabilizer and binder used in lotions and other products. Though it is not a concern in itself, it is made up of repeating molecules of acrylamide, which is a strongly suspected carcinogen linked to mammary tumours.

 

Styrene. Residual styrene may be a contaminant in cosmetics with styrene-based ingredients or fragrances that contain styrene. Styrene is reasonably anticipated to be a human carcinogen and a hormone disruptor. Styrene may also be toxic to red blood cells, the liver, and the central nervous system.

 

Phthalates are endocrine disruptors and can disrupt estrogen, progesterone and androgen systems. They are commonly found in plastics, building materials, cleaning products, insecticides, pharmaceuticals, food packaging, home décor, children’s toys, and personal care products. For pregnant women, phthalates are associated with decreased fertility, pregnancy loss, and adverse obstetrical outcomes. They also affect the way the body produces and uses the hormone testosterone, which is present in varying amounts in all bodies. 

 

Parabens are used as preservatives in many cosmetic products, including makeup, moisturisers, hair care products, and shaving creams or gels. However, they disrupt the way your body produces and regulates oestrogen and other hormones. Parabens can penetrate the skin and act like a very weak oestrogen in the body— potentially turning on the growth of hormone-receptor-positive breast cancers.

 

1,4-dioxane is formed in the manufacture of ingredients used as foaming agents in shampoos, body wash, and children’s bath products. It is defined as a carcinogen by the National Toxicology Program and the International Agency for Research on Cancer.

 

Sunscreens (UV filters). Several UV filters used in cosmetics may have hormone-disrupting properties, including benzophenone, homosalate, and octinoxate. Prominently found in sunscreen, these chemicals are also used in a variety of personal care products such as shampoos, lipstick, nail polish and skin creams. 

 

Polytetrafluoroethylene (PTFE) is found in some anti-ageing products. PTFE may be contaminated with PFOA (perfluorooctanoic acid), a possible carcinogen. Exposure to these compounds is associated with delayed menstruation, later breast development and increased incidence of breast cancer.

 

Triclosan is used in many products to prevent bacterial growth and mould and to kill bacteria on the surface of the skin. It's found in anti-acne products, some deodorants and antiperspirants, and sanitising hand soaps. Some evidence shows that it disrupts the microbiome within the gut. Further, the chemical is classified as a pesticide and can affect the body’s hormone systems—especially thyroid hormones, which regulate metabolism—and may disrupt normal breast development.
