9 Sneaky Ingredients to Watch Out for in Skin Care Products

Could one of these be the mean culprit in your skin care regimen?

Alcohol

You'll often find alcohol or ethanol in toners and other skin care products that tout de-greasing and oil-zapping benefits.

"While alcohol and ethanol can degrease the skin, they can be very irritating and drying, stripping your skin of its protective barrier," says Dr. Charlotte Birnbaum, a board-certified dermatologist at Spring Street Dermatology. "It does little to improve skin and the dryness it causes prevents tolerability of more proven anti-aging and anti-acne ingredients, like retinols."

In general, she says to avoid products with ethanol, denatured alcohol, ethyl alcohol, isopropyl alcohol, SD alcohol, or benzyl alcohol.

Chemical Sunscreens

The "chemical versus physical" sunscreen has been an ongoing debate in the dermatology world, and ultimately what matters most of all is that you're wearing SPF at all. That said, there's an increasing number of dermatologists who advocate for mineral-based sunscreens, and there's fortunately been an uptick in sophisticated, lightweight, easy-to-wear formulations.

"Physical sunscreens block a wide range of UV wavelengths, they are photostable, and there are fewer concerns about their potential adverse effects both to the body and to the environment," explains Dr. King. "Additionally, physical sunscreens are less likely to clog pores and irritate complexions, particularly for those with sensitive skin."

Examples of chemical sunscreen ingredients include avobenzone, octinoxate, and oxybenzone, while mineral-based sunscreen ingredients are typically zinc oxide and titanium dioxide. One of our favorite mineral sunscreens is Versed Guards Up Daily Mineral Sunscreen Broad Spectrum SPF 35, $21.99.

Formaldehyde and Formaldehyde-Releasing Agents

This might sound like something you don't have to worry about, but formaldehyde (and formaldehyde-releasing agents) are actually still found in skin care products and cosmetics.

Dr. King says, "These are a common cause of contact dermatitis and irritation of the skin. Formaldehyde is also a known carcinogen. Specifically, quaternium-15, DMDM-hydantoin, imidazolidinyl urea, and diazolidinyl urea are all formaldehyde releasers."

These ingredients are typically incorporated to kill microorganisms, but there are alternatives that do work. Check the ingredient list for these biggies and avoid them.

Methylisothiazolinone (MI)

It's not just a tongue twister, methylisothiazolinone is a common skin care ingredient that can cause allergic reactions in many skin types. "MI is a preservative used to prevent bacterial overgrowth in cosmetics and household products, such as make-up remover wipes, shampoos, deodorants, detergents, moisturizers, make-up, and baby wipes," says Dr. Birnbaum. "It is one of the most common ingredients to cause allergic contact dermatitis."

Fragrance/Parfum

Here's another skin care ingredient situation where YMMV, but generally speaking, your skin will appreciate it when you reach for non-fragranced products. Especially if you have sensitive or compromised skin.

"Many fragrances are skin and eye irritants. They are also common culprits of allergic reactions and can even trigger headaches and dizziness," notes Dr. Murphy-Rose. "Contact dermatitis occurs after exposure to an offending ingredient, and fragrance is one of the most common triggers. Contact dermatitis usually appears as pink or red scaly dry-appearing rashes that may itch."

Dr. Birnbaum adds that you should look for "fragrance-free" products over "unscented" products. "'Unscented' products can use a masking fragrance to mask an unpleasant smell to produce a neutral smell, but they are still fragranced," she says.

Fortunately, there are plenty of fragrance-free products out there, including products by Vanicream, First Aid Beauty, Cetaphil, and Cerave. Try Klairs Rich Moist Soothing Cream, $25.
