For adults, citric acid is usually safe in skin products when used at low levels. It's often added to change acidity and keep products stable. The main risk is stinging or irritation, especially in strong formulas or on damaged skin.
Patch-test any new product with citric acid on a small area before using it on your face or large areas. Prefer rinse-off products or leave-on products that list low concentrations. Avoid using strong DIY or high-acid products near the eyes, on broken skin, or on very sensitive areas. If you feel burning, severe stinging, or see a rash, stop using it and rinse the area. If you have concerns about using acids while pregnant or breastfeeding, ask your healthcare provider.
Health Canada has placed restrictions on some cosmetic uses of citric acid — avoid products that don’t provide safe-use information. Industry reviewers (Cosmetic Ingredient Review) note there are gaps about maximum safe concentrations in finished products, so be cautious with high-strength or home-made acid products. Although the U.S. Food and Drug Administration allows certain uses in food, that does not mean strong topical products are always safe. Watch for redness, stinging, burning, or rash and avoid use on broken or inflamed skin. If irritation continues, seek medical advice.
