Is Stearyl Heptanoate comedogenic?
Yes — Stearyl Heptanoate is considered highly comedogenic, scoring 4 out of 5. That means it has a strong tendency to block pores and is a well-known trigger for closed comedones, blackheads and breakouts on acne-prone skin. If your skin is oily or congestion-prone, Stearyl Heptanoate is one of the ingredients most worth avoiding in leave-on facial products, though it can still be fine in short-contact rinse-off products or on the body.
Does Stearyl Heptanoate cause fungal acne?
Separately from pore-clogging, Stearyl Heptanoate is considered a potential fungal-acne (Malassezia) trigger. Fungal acne — properly called Malassezia folliculitis — appears as small, uniform, sometimes itchy bumps, and is fed by certain oils, fatty acids and esters. This is a different problem from comedogenic clogging, so if you are prone to fungal acne you may want to avoid Stearyl Heptanoate even when its comedogenic rating is low.
Should you use Stearyl Heptanoate if you're acne-prone?
If you are acne-prone, it is safest to keep Stearyl Heptanoate away from your face in leave-on products. It can still be useful for dry body skin, hair, or in cleansers where it is quickly rinsed off. Normal and dry skin types often tolerate it without issue.
