Is Decyl Oleate comedogenic?
Decyl Oleate sits in the moderate-to-high range at 3 out of 5. It can clog pores for some people — particularly those who are very acne-prone — but is better tolerated than the worst offenders. If you break out easily, patch-test Decyl Oleate and watch how your skin responds over two to three weeks before using it regularly.
Does Decyl Oleate cause fungal acne?
Separately from pore-clogging, Decyl Oleate 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 Decyl Oleate even when its comedogenic rating is low.
Should you use Decyl Oleate if you're acne-prone?
If you are acne-prone, it is safest to keep Decyl Oleate 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.
