Paba, Benzophenone, Parabens, Padimate-O

So what exactly do you need to avoid when choosing a sunscreen? Here are some unsavory, even toxic, ingredients you will want to stay away from if you can:

PABA: This is not widely used anymore, but just in case. Many people are very sensitive to this ingredient and can end up with red, itchy skin.

Benzophenone (benzophenone-3), homosalate, and octy-methoxycinnamate (octinoxate): These chemicals are bad news because they have shown estrogenic activity in lab tests. Oxybenzone is aderivative of benzophenone and it is linked to allergies, hormone disruption, and cell damage. According to the CDC 97% of Americans are contaminated with this widely-used sunscreen ingredient.

Parabens (butyl-, ethyl-, methyl-, and propyl-): Parabens are common in sunscreens so avoiding them may prove difficult. They are preservatives that have estrogenic qualities. They have produced abnormal hormonal effects following on laboratory rodents, particularly male, resulting in decreased testosterone levels and other abnormalities. They have also been found to accumulate in the breast tissue of women with breast cancer.

Padimate-O and Parsol 1789 (Avobenzone): While on the surface of the skin these chemicals appear to prevent UV damage but when absorbed into the skin they can actually damage DNA. There is evidence that the sun’s light may cause these chemicals to become reactive and cause free-radical damage when they’re absorbed. I find it alarming that pediatricians often recommend these very ingredients.

In general if you want to know which sunscreens are usually loaded with the bad stuff….oh just the easy to find ones like Coppertone, Banana Boat, Avon, Nivea, Neutrogena, The Body Shop, etc. Also even some of the ones that appear to be more natural like Kiss My Face or Aveeno have some pretty dirty sunscreens.
