13 Ingredients You Should Avoid In Your Makeup + Skincare (And Why)

6 min read

With more awareness about ingredients in food and personal care products coming to light, there’s been a pendulum swing for many consumers, and more people are asking: How do we know what’s actually safe to put on our bodies? In the largely unregulated cosmetics industry—there hasn’t been federal legislation regarding beauty and personal care products since 1938, and the United States only bans or partially bans 30 ingredients while the European Union has restrictions on more than 1,400—we have to be our own advocates by reading labels, asking questions and staying informed.

According to a 2004 study by the Campaign for Safe Cosmetics, the average adult uses nine personal care products on a daily basis. Those cosmetics contain an average of 126 chemical ingredients, many of which are linked to cancer, hormone disruptions or bad allergies. So, how do you know what’s been linked to health issues, and what to avoid? At WELL Summit Brooklyn 2018 on  October 5 and 6, we hosted a panel called Clean Your Daily Routine. Experts weighed in on why it’s important to pay attention to your personal care products, and told attendees how to avoid potentially harmful ingredients.

Read on for which ingredients they agree you should start checking your labels for.

Staring down a list like that can be overwhelming. But it doesn’t have to be. Start simple, by replacing products you run out of and finding greener alternatives. A few certifications that can help guide consumers include:

  1. MADE SAFE: From mattresses to baby toys, cosmetics to bodycare, MADE SAFE products are rigorously tested to ensure safety in all parts of the formulation process.
  2. Think Dirty: A portable way to check your cosmetics before purchasing them. Just use their handy app to scan the barcode of the product, and you’ll get info about its ingredients.
  3. ECOCERT: ECOCERT was the very first certification body to develop standards for “natural and organic cosmetics,” and its label means it’s been third-party verified.
  4.  EWG Healthy Living App: Another way to scan products before buying, this app includes cosmetics, cleaning and food items.
