Safety of Preservatives in Cosmetics

Preservatives like parabens are used to extend the shelf life of products. Despite concerns about endocrine disruption, research indicates that the concentrations used are safe and based on toxicology data. Older preservatives with longer carbon chains have been phased out as a precautionary measure, even though no actual harm has been observed in humans. Products without effective preservatives can spoil faster.
