While some skincare brands have been making an effort to exclude parabens from their formulas, these preservatives can still be found in a vast majority of skincare products on the market.
Why is this a problem? Parabens mimic estrogen in the human body, disrupting our hormonal balance. They've been linked to breast cancer and can lead to reproductive and fertility issues.
Petroleum, another widely used ingredient in personal care products, is an "occlusive" agent, meaning it seals off the skin. You know what that means? Clogged pores. More offensive yet, some studies have deemed petroleum products carcinogenic.
Chemical sunscreens, which are derived from petroleum, should also be avoided. Much like parabens, chemical sunscreens are endocrine disruptors and have been linked to reproductive issues and cancer.
Silicones give lotions and creams their smooth, silky texture. While they're considered non-toxic, they do little to benefit your skin.
Silicones create a barrier on your skin that can clog pores and prevent other ingredients from being absorbed.
Because silicones can be difficult to remove, they also inhibit the process of cell renewal, giving skin a dull and lifeless appearance.
