Is Octyl Stearate Comedogenic?
Comedogenic rating: 5/5 — Very likely to clog pores
Octyl Stearate is an emollient ester that gives products a smooth, silky slip and cushiony feel. In cosmetics it is typically found in moisturizers, foundations, lipsticks, primers and sunscreens. On a label it may also appear as ethylhexyl stearate.

Is Octyl Stearate comedogenic?
Yes — Octyl Stearate is considered highly comedogenic, scoring 5 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, Octyl Stearate 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 Octyl Stearate cause fungal acne?
Separately from pore-clogging, Octyl Stearate 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 Octyl Stearate even when its comedogenic rating is low.
Should you use Octyl Stearate if you're acne-prone?
If you are acne-prone, it is safest to keep Octyl Stearate 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.
