Is PEG-16 Lanolin comedogenic?
Yes — PEG-16 Lanolin 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, PEG-16 Lanolin 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 PEG-16 Lanolin cause fungal acne?
PEG-16 Lanolin is generally considered fungal-acne (Malassezia) safe. It is not among the oils, fatty acids or polysorbates known to feed Malassezia yeast, so it should not aggravate fungal acne (Malassezia folliculitis) for most people.
Should you use PEG-16 Lanolin if you're acne-prone?
If you are acne-prone, it is safest to keep PEG-16 Lanolin 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.
