For adults, benzoic acid is generally safe when used in skin products at the amounts set by manufacturers. It is a common preservative and is not thought to cause cancer or major health problems in grown-ups when used as intended.
Buy products from trusted brands that follow ingredient limits. Use products as directed. If you have sensitive skin, do a small patch test on your inner arm before putting it on larger areas. If a product gives you a rash, stop using it and wash the area.
Some safety reviews and regulators note limits on how much benzoic acid should be used in cosmetics (Cosmetic Ingredient Review and Japan Ministry of Health), and there are some data gaps noted by environmental and health agencies (for example the EPA). Watch for skin irritation, allergic reaction, or redness and avoid use on broken skin. If pregnant or nursing, or if you have strong skin sensitivity, talk with your healthcare provider before regular use.
