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.
Propylene Glycol
Propylene glycol is another very common ingredient found in skin care, and generally speaking it's considered safe. However, Dr. Murphy-Rose warns that it is often associated with contact dermatitis. "Further," she adds, "Propylene glycol enhances the penetration of other ingredients into the skin which can make susceptible users more at risk of reactions to those other ingredients. It's a good idea to avoid this ingredient, especially in patients with sensitive skin."

Artificial / Synthetic Dyes
We hate to be the bearer of bad news, but Dr. Murphy-Rose says that "many artificial or synthetic dyes that may be found in makeup like mascara are thought to be carcinogenic and toxic." She says it's best to avoid ingredients starting with FD&C or D&C with a color and number.
"Some of these contain heavy metals and are known to be carcinogenic and associated with lymphomas and multiple myeloma. Coal tar dyes can cause severe allergies and trigger asthma attacks, headaches, nausea, and other systemic effects. They have been prohibited in cosmetics in Canada," she says.
Instead, reach for cosmetics that utilize natural dyes. More are being discovered and utilized in beauty products every day! For example, Ere Perez Beetroot Cheek & Lip Tint, $26, uses beetroot to get that gorgeous color.
