Fathoming the Skin Care Cancer Connection

Our skin absorbs what we put on it. Some ingredients in skincare products have been linked to cancer. The good news is that you can lower your risk by knowing which ingredients to avoid and choosing safer alternatives.

How Chemicals Get Into Your Body

Chemicals in skincare products can enter your body in a few ways:

• Absorption: Skin absorbs chemicals directly into the bloodstream.
• Inhalation: Sprays and powders release chemicals into the air that you breathe in.
• Ingestion: Lipsticks and lip balms can be swallowed.

Who Regulates Skincare Ingredients?

Government agencies like the Food and Drug Administration (FDA) regulate cosmetics. However, regulations are not always strict. Many chemicals haven’t been fully tested for safety. This is why you need to be informed and make smart choices.

Major Culprits: Ingredients to Watch Out For

Many ingredients have been linked to cancer. Here’s a detailed look at some of the most concerning:

Parabens

• What they are: Preservatives that prevent the growth of bacteria and mold.
• Why they’re concerning: Can mimic estrogen in the body. High estrogen levels have been linked to breast cancer.
• Where they’re found: Lotions, shampoos, conditioners, makeup.
• How to spot them: Look for ingredients ending in “-paraben” (e.g., methylparaben, propylparaben, butylparaben).

Phthalates

• What they are: Plasticizers that make products more flexible and fragrances last longer.
• Why they’re concerning: Disrupt hormone function and have been linked to developmental and reproductive problems, as well as some cancers.
• Where they’re found: Nail polish, hair spray, perfumes, lotions.
• How to spot them: Often listed as “fragrance” or “parfum” on labels. Look for specific phthalates like dibutyl phthalate (DBP), diethyl phthalate (DEP), and dimethyl phthalate (DMP).

Formaldehyde and Formaldehyde-Releasing Preservatives

• What they are: Formaldehyde is a known carcinogen. Some preservatives release formaldehyde over time.
• Why they’re concerning: Formaldehyde exposure can cause cancer, especially of the nose and throat, and leukemia.
• Where they’re found: Nail polish, hair straightening products, eyelash glue.
• How to spot them: Look for formaldehyde, but also these formaldehyde-releasing preservatives:
  • DMDM hydantoin
  • Diazolidinyl urea
  • Imidazolidinyl urea
  • Quaternium-15
  • Bronopol (2-Bromo-2-Nitropropane-1,3-Diol)
  • 5-Bromo-5-Nitro-1,3-Dioxane
  • Sodium Hydroxymethylglycinate

Oxybenzone and Octinoxate in Sunscreen

• What they are: Chemical UV filters in sunscreen.
• Why they’re concerning: Oxybenzone can disrupt hormones and may be linked to cancer. Octinoxate is also a hormone disruptor.
• Where they’re found: Chemical sunscreens.
• How to spot them: Check the active ingredients list.

Coal Tar Dyes

• What they are: Dyes made from coal tar.
• Why they’re concerning: Coal tar is a known human carcinogen.
• Where they’re found: Hair dyes, shampoos, and some makeup.
• How to spot them: Look for ingredients listed as “CI” followed by a number (e.g., CI 77891), or “FD&C” or “D&C” followed by a color and number (e.g., FD&C Red No. 6).

Talc

• What it is: A mineral used to absorb moisture and prevent caking.
• Why it’s concerning: Talc can be contaminated with asbestos, a known carcinogen.
• Where it’s found: Powder, eyeshadow, blush.
• How to spot it: Look for “talc” on the ingredient list.

1,4-Dioxane

• What it is: A byproduct of ethoxylation, a process used to make ingredients less harsh.
• Why it’s concerning: A likely human carcinogen.
• Where it’s found: Products that create suds, such as shampoos, body washes, and bubble baths.
• How to spot it: It’s not usually listed as an ingredient. Look for ingredients like:
  • Sodium laureth sulfate
  • PEG compounds (e.g., PEG-100 stearate)
  • Polyethylene
  • Polyoxyethylene

Lead

• What it is: A heavy metal that can be a contaminant in cosmetics.
• Why it’s concerning: A known carcinogen and neurotoxin.
• Where it’s found: Lipstick, eyeliner, foundation.
• How to spot it: Lead is not always listed as an ingredient. Look for products with “long-lasting” color, as they may contain more lead.

Digging Deeper: Evidence of Skincare Cancer Risk

Research shows that some skincare ingredients can increase cancer risk.

Studies on Parabens

Some studies have found parabens in breast cancer tumors. While these studies don’t prove parabens cause cancer, they raise concerns. Parabens can mimic estrogen, which can fuel the growth of some breast cancers.

Studies on Phthalates

Phthalates have been linked to hormone disruption and reproductive problems. Some animal studies have linked phthalates to liver and testicular cancer.

Studies on Formaldehyde

Formaldehyde is a known human carcinogen. Exposure to formaldehyde has been linked to leukemia and cancers of the nose and throat.

Studies on Sunscreen Ingredients

Some studies suggest that oxybenzone can disrupt hormones. More research is needed to fully understand the long-term effects of sunscreen ingredients on human health.

Examining the Research: Table Summarizing Findings

Ingredient	Cancer Type(s) Linked To	Study Type	Key Findings
Parabens	Breast Cancer (potential estrogenic effects)	Laboratory Studies, Observational Studies	Found in breast tumor tissue; can mimic estrogen
Phthalates	Liver, Testicular Cancer (in animals)	Animal Studies, Epidemiological Studies	Hormone disruption; reproductive problems
Formaldehyde	Leukemia, Nasopharyngeal Cancer	Human Studies, Occupational Exposure Studies	Known human carcinogen; increased risk with prolonged exposure
Oxybenzone	Potential Hormone-Related Cancers (hormone disruption)	Laboratory Studies, Animal Studies	Hormone disruption; limited human studies
Talc (contaminated)	Ovarian Cancer, Lung Cancer (if inhaled and contaminated)	Epidemiological Studies, Case-Control Studies, Occupational Studies	Association with ovarian cancer when used genitally; lung cancer in talc miners
Coal Tar	Skin Cancer	Occupational Studies	Increased risk in workers exposed to coal tar
1,4-Dioxane	Liver and Nasal Tumors (in animals)	Animal Studies	Classified as a likely human carcinogen
Lead	Brain, Kidney, other Cancers	Animal and Human Studies	Demonstrated Carcinogenic Potential

Taking Action: How to Protect Yourself

Protecting yourself involves reading labels, choosing safer products, and advocating for stricter regulations.

Reading Labels

Always read the ingredient list on skincare products. Look for the ingredients listed above and choose products without them.

Choosing Safer Products

• Look for “fragrance-free” products: This can help you avoid phthalates.
• Choose mineral sunscreens: These use zinc oxide or titanium dioxide, which are considered safer than chemical UV filters.
• Buy from trusted brands: Research brands that are transparent about their ingredients and committed to safety.
• Opt for certified organic products: These products are made with ingredients that have not been treated with harmful chemicals.

Safer Alternatives: Examples

Ingredient to Avoid	Safer Alternative
Parabens	Phenoxyethanol, Sodium Benzoate, Potassium Sorbate
Phthalates	Fragrance-free products, essential oils
Formaldehyde releasers	Other preservatives like sodium benzoate, potassium sorbate
Oxybenzone/Octinoxate	Zinc oxide, titanium dioxide
Talc	Cornstarch, rice starch

Advocating for Safer Cosmetics

Support organizations that advocate for stricter regulations on cosmetics. Contact your elected officials and urge them to support legislation that would require more thorough testing of skincare ingredients.

The Future of Skincare Safety

The future of skincare safety depends on increased awareness, stricter regulations, and ongoing research. By staying informed and making smart choices, you can protect yourself from potentially harmful chemicals.

Stricter Regulations are Needed

Current regulations are not strict enough to protect consumers from harmful chemicals. Stronger laws are needed to require more thorough testing of skincare ingredients and to ban the use of known carcinogens.

Innovation and Green Chemistry

Green chemistry focuses on designing safer chemicals and processes. This approach can help create skincare products that are effective and safe for human health and the environment.

Staying Informed

Stay up-to-date on the latest research on skincare ingredients and cancer risk. Follow reputable organizations and experts in the field.
