By safe cosmetics, we mean non-toxic, i.e., not poisonous. Non-toxic beauty and personal care products are generally safe to eat, breathe, and absorb into your body. They don’t contain chemicals harmful to human health or the environment. There’s no way to guarantee any substance as truly ‘safe’ – water is non-toxic and yet is not safe to consume in very vast quantities in a short time frame, for example. However, when we say safe, we mean not linked to serious health effects like cancer, developmental or reproductive harm, neurological harm, endocrine disruption, organ-system toxicity, allergies or irritation, or environmental harm.
