Silica Dimethyl Silylate and fungal acne
No known trigger
Why it's not a known trigger
Inorganic fumed silica with dimethylsilyl surface groups; no C11-C24 chain, no ester and no triglyceride, so lipases cannot release a fatty acid from it.
A silicone-coated mineral powder used to thicken oils and give a smooth feel; there is no fat in it for Malassezia to feed on.
