Formaldehyde is a known irritant and allergen, and prolonged exposure to it can cause skin irritation, respiratory issues, and potentially increase the risk of cancer. To avoid formaldehyde exposure, look for products labeled as formaldehyde-free or check ingredient lists for formaldehyde-releasing preservatives like DMDM hydantoin, imidazolidinyl urea, and diazolidinyl urea.
When using products that contain formaldehyde, it is important to follow safety guidelines, such as using them in well-ventilated areas and wearing protective gloves if necessary.
