WHAT ARE PARABENS?
Parabens get a bad name because they are synthetic. In an article for Allergic Living, Dr Sandy Skotnicki, Dermatologist, advises that parabens are safe to use on normal healthy skin. "The one area where parabens can cause problems is with inflamed skin. This is known as the “Paraben Paradox”. And, "In essence, parabens almost never cause a problem on normal skin, but can cause allergic dermatitis when used on active skin disease, such as wounds or eczema. This is why parabens are never used to preserve topical hydrocortisone creams or antibiotic ointments." - Allergic Living.
Parabens prevent bacteria from growing in products like moisturisers that repeatedly come into contact with germs from your hands as you apply it to your face. "The American Chemical Society estimates that parabens are in about 85% of personal care products -- everything from shampoo to shaving cream. Researchers believe most of us get our greatest exposure from these products as they’re absorbed through the skin." - Brenda Goodman, MA
In an article for Healthland.time.com it is noted that "[T]he SCCS considers the use of Butylparaben and Propylparaben as preservatives in finished cosmetic products as safe to the consumer, as long as the sum of their individual concentrations does not exceed 0.19%"
