Frequently asked questions
What does PEG-8 Dimethicone do in skincare?
PEG-8 Dimethicone is a cosmetic ingredient used in skincare formulas. The catalog calls its main role “surfactant - cleansing.” In plain language, it helps water lift oil and residue from the skin. The catalog lists 1 other possible role for this ingredient. These labels do not prove that it treats a skin condition.
Is PEG-8 Dimethicone a fungal-acne (Malassezia) trigger?
Chemistry gives a clear reason these shouldn't feed Malassezia: mineral oil and petrolatum are saturated hydrocarbons with no ester bond for a lipase to hydrolyse and no fatty acid to release; silicones (dimethicone, cyclomethicone) aren't lipids in the sense the yeast metabolises; squalane's saturated backbone has no double bonds to oxidise the way squalene does. Malassezia is a lipid-dependent yeast that grows on specific fatty acids, so ingredients carrying no usable fatty acid fall outside what it can metabolise. This is reasoned from that chemistry rather than a dedicated study of each ingredient — a thinner evidence base than the flagged ingredients above, but a well-founded one.
