Parabens are preservatives used to keep health and beauty products fresh by preventing the growth of harmful bacteria. These compounds are amongst the most commonly used cosmetic preservatives in the world and have a long history of safe use. Parabens have been extensively studied and use in cosmetic products is allowed by regulatory authorities around the world.
Short story: Our cleansers, masks, toners, and scrubs are paraben-free. Our pore strips do contain the minimal amount of methylparaben required to function as a preservative, which is a safe paraben for cosmetic use.
Methylparabens are the most common preservative used in food and cosmetics. In the United States, methylparaben and propylparaben are recognized as safe by the FDA.
The Food and Drug Administration (FDA) is a federal organization responsible for protecting public health by ensuring the safety, efficacy, and security of human and veterinary drugs, biological products, and medical devices, our nation's food supply, cosmetics, etc.Other independent groups, the American Cancer Society, the FDA, and Cancer Research Centers, have looked for many different causes for cancer but have never found any evidence of risk from parabens.

Alcohol is a universal, commonly used solvent ingredient that tones, cleanses, and disinfects skin. It also helps formulas mix together consistently.
Short story: Yes, in some of our products, such as our Witch Hazel Pore Clarifying Toner.
Alcohol is a key cleansing ingredient used to break down skin residue like oils/sebum, as well as makeup and cleanser residue. Alcohol also provides astringency to tone the skin. When used properly in formulations like ours, alcohol is safe and effective
Microbeads are an exfoliant found in many rinse-off cosmetics. Their use in toothpaste and skincare products has raised some environmental concerns if the microbeads contain plastic.
Short story: No, Bioré® products do not contain any plastic microbeads. We use natural exfoliating alternatives, such as jojoba beads.
For years, none of our products have contained plastic microbeads. Our Formulation Scientists purposefully design our formulas to avoid these materials while still providing the benefits and experience you expect.
As part of our commitment to sustainability, we are always looking for ways to improve our products to protect the environment.

Our fragrance philosophy places the utmost importance on research, analysis, assessment and transparency. Our in-house team of experts is dedicated to creating fragrances that can be enjoyed safely. That’s why our formulations are compliant and backed by safety data and meet the guidelines of the International Fragrance Association (IFRA). And we are striving to improve transparency, so that accurate information about products and ingredients is accessible for everyone.



We know you LOVE animals and so do we! That’s why all the Bioré® products in our western markets are cruelty-free and vegan friendly. We do not test our products or the materials within them on animals and we do not use any animal-derived ingredients.
We follow the conventions of the EU and other governmental bans on animal testing for cosmetics. Occasionally, laws and regulations require testing of materials outside of the cosmetics category. Since the 1980’s, Kao Corporation has been actively working together with industry associations and relevant third parties to find robust alternatives to animal testing, which have been successfully adopted as international guidelines.
