What Ingredients to Avoid in Skincare
Skincare Ingredients You Should Always Avoid
“In addition to being a common cause of contact dermatitis—characterized by rashes and blisters—and skin irritation, formaldehyde is also known as a carcinogen,” says Dr. King. Unfortunately formaldehyde, which is used as a preservative to extend shelf life, can be found in many beauty staples, including nail polish, nail polish removers, eyelash glue, and hair straightening products. But it shouldn’t stop at just eliminating formaldehyde—there are also formaldehyde releasers, substances that emit formaldehyde over time to continue the preservation process. “Quaternium-15, DMDM-hydantoin, imidazolidinyl urea, and diazolidinyl urea are all formaldehyde releasers,” shares Dr. King.
“According to the European Commission’s Scientific Committee on Consumer Products, certain long chain parabens may disrupt the endocrine system and cause reproductive and developmental disorders,” she says of the preservative.
“Some studies have shown that phthalates can change hormone levels,” says Dr. King. “Phthalates may contribute to endocrine disruption, breast cancer risk, and negatively affect the male reproductive system.” It’s also important to note that due to its low molecular weight, these plasticizers may be absorbed through the skin more easily.
Found in everyday essentials like liquid soap and laundry detergent, sulfates—which are favored by companies due to its ability to produce a lather—may cause dry, irritated skin. This may be due to the stripping of the skin’s naturally produced oils.
While this antimicrobial kills bacteria, fungus, and other microbes, “studies have linked it to a number of different problems including disruption of the endocrine system and the increased risk of cancer,” according to Dr. King.
This ingredient is found in freezing mixtures, batteries, dyes, safety explosives, and in urinary acidifiers and diuretics. “If ingested, it can cause nausea, vomiting, and acidosis in doses of 0.5 to 1 gram,” adds Dr. King. “As with any ammonia compound, concentrated solutions can be irritating to the skin.”
