What is Stearyl Heptanoate?
An ester of stearyl alcohol used as a waxy emollient in lipsticks, mascaras, and creams, where it adds gloss and structure.
What to do if you're acne-prone
Skip it in leave-on products like moisturizers, sunscreens, and foundations if you're acne-prone. In rinse-off products the risk is lower but not zero.
Where this rating comes from
Our ratings consolidate two lineages: the original rabbit-ear comedogenicity assays published by James Fulton and colleagues (Fulton, Pay & Fulton, Journal of the American Academy of Dermatology, 1984; Fulton, Journal of the Society of Cosmetic Chemists, 1989), and the pore-clogger lists maintained by acne-specialist estheticians in the Face Reality lineage that refine those assays with decades of client observation. Both source lineages agree on this ingredient's rating.

Comedogenicity ratings come from published ingredient studies and esthetician-compiled lists. They are imperfect and formulation-dependent, and this page isn't medical advice. Reactions vary by skin, concentration, and the rest of the formula.
