These might appear on the ingredient list as methyparaben, benzylparaben, or others ending with the same word and work as very effective preservatives. Since parabens appear to mimic the activity of astrogen in the body, concerns have been raised that they may affect the endocrine system, leading to decreased sperm counts in men and even breast cancer in women.
A few studies found parabens in a small sample of cancerous breast tumors, but they did not prove parabens caused the cancer. One study has shown that even a very strong paraben is 10,000 to 100,000 times less active than estrogen itself, and most products that use parabens contain very low levels.
Therefore, the FDA currently states that parabens are safe for use in cosmetics. Nevertheless, EILEEN MAI® products do not contain any parabens to ensure your skin receives only the most healthful ingredients.
