What can render a cosmetic injurious to users?

The presence of harmful or toxic ingredients in a cosmetic product is a significant factor in determining whether it may be injurious to users. These harmful substances can lead to adverse health reactions, skin irritations, allergies, or even long-term health issues depending on their nature and concentration. The safety of cosmetic products is heavily regulated, and the formulation must be evaluated for safety, efficacy, and potential side effects.

While certifications, labeling claims such as being organic, and where the product is sold can influence the perception of safety, they do not inherently ensure that a cosmetic product is free from hazards. It's crucial for consumers to be aware of ingredient lists and any potential toxins that may cause harm, regardless of other factors. Therefore, the potential for injury directly links to the specific contents of the product rather than the professional status of the applicator, marketing terms, or retail settings.
