Methyl Trimethicone
A lightweight silicone that gives a smooth, silky finish to serums and primers. Like other silicones, it is often wrongly feared as pore-clogging; published assessments and dermatology data do not support that concern.
The silicone fear assumes dimethicone and its cousins seal pores or suffocate skin. Silicones are breathable to water vapor and non-comedogenic in testing. The clean-beauty rejection is positioning, not evidence-based.
