You're not alone. With ingredient names you can’t even pronounce, it’s tough to tell what's harmful and what’s harmless—especially if you have sensitive or acne-prone skin. Some ingredients might work for many, but not for everyone.
To help you navigate the labels, here are 6 ingredients commonly found in face oils that you should avoid. Keep these in mind the next time you're out shopping.
# Unnatural: Mineral Oil & DimethiconeAlso listed as: Petrolatum, Liquid Paraffin, Paraffin Oil
Mineral oil and dimethicone are often used in face oils for their ability to seal in moisture and create a smooth texture. However, they are not naturally derived. Their occlusive nature prevents not only moisture from the air but also other active ingredients from penetrating the skin—limiting the overall benefits of your skincare.
Better Alternative: Opt for natural emollients that nourish deeply and support skin regeneration rather than just forming a barrier.
# Unnecessary: Water, PEGs & PreservativesWater has no real place in face oils—its presence calls for added preservatives, which in turn invite more questionable chemicals like PEGs.
Common culprits include:
- PEG compounds (which may be contaminated with toxins like 1,4-dioxane or heavy metals)
- Preservatives such as Triclosan, parabens, and methylisothiazolinone
According to the International Journal of Toxicology, PEGs may carry various contaminants harmful to health. In face oils, where hydration comes from oils—not water—these extras are unnecessary.
# BHA / BHTAlso listed as: Butylated Hydroxyanisole (BHA), Butylated Hydroxytoluene (BHT)
These synthetic antioxidants help prolong shelf life, but at a cost.
- BHA is considered a possible human carcinogen by the International Agency for Research on Cancer
- Both BHA and BHT are linked to hormone disruption and allergic skin reactions
Safer Swap: Natural vitamin E (alpha-tocopherol) is a stable, non-toxic antioxidant that offers similar benefits without the health risks.
# Fragrance (Parfum)We all love pleasant-smelling skincare—but fragrance is often a cocktail of undisclosed chemicals. Brands aren't required to list what’s inside, and many of these hidden ingredients can trigger allergies or sensitivities.
Tip: If you have sensitive skin or you're unsure what's in the fragrance, it's best to skip it.
