Isostearic Acid
May cause Acne
Some ingredients have a higher likelihood of clogging pores or triggering breakouts, especially for acne-prone skin. However, skin reactions are individual - what causes breakouts for one person may work fine for another. Patch test if you're concerned.
May feed Fungal Acne
Non-fungal acne-safe products contain ingredients that can worsen fungal acne. If you suspect fungal acne, consult a dermatologist for proper diagnosis.

Isostearic Acid is created from oleic acid.
This ingredient may not be Malassezia folliculitis, or fungal-acne safe.
