Parabens are a group of preservatives used in cosmetics to prevent the growth of bacteria and mold. They are commonly found in makeup, moisturizers, hair care products, and shaving products. Parabens are effective in preventing the growth of mold, fungi, and harmful pathogens. However, some studies have raised concerns about their potential health effects, including skin irritation, allergic reactions, and endocrine disruption.

Some studies determined a 100% concentration of parabens caused skin samples (meaning not intact skin on a person) to break down. However, these studies don’t apply to the tiny amount (1% or less) of parabens typically used in cosmetics. Parabens may produce irritation in previously sensitized or damaged skin in humans and in laboratory animals; sensitized individuals may also react to parabens. In addition, chronic skin reactions have been reported, including urticaria and angioedema.
Parabens are one of the most effective broad-spectrum preservatives out there. The beauty of parabens is that you can really use them at a low percentage.
Parabens are found in plants in the form of p-hydroxybenzoic acid (PHBA), a chemical that breaks down to become parabens for a plants own protection.
The National Cancer Institute also noted that there is no evidence that parabens cause breast cancer and included a footnote to a 2019 report by the industry-funded Cosmetic Ingredient Review’s expert panel, which concluded that 20 of the 21 parabens in the report are safe in cosmetics as long as the total in a product is less than 0.8 percent.
The activist organization’s science, tactics and publications, including its annual “Dirty Dozen” list of produce most likely to be contaminated by pesticides, have been questioned by experts.
Parabens are often used in combination with other types of preservatives to better protect against a broad range of microorganisms. Parabens are cheap and effective as preservatives, and the only alternative to removing preservatives is for the shelf life to be reduced dramatically. Parabens do not accumulate in the skin or other body organs. Parabens are rapidly absorbed in the gastrointestinal tract, promptly hydrolyzed by the liver, and then conjugated to sulfate and glucuronide and eliminated in the urine within hours.
