Our take
Is PEG-12 Dimethicone a Good Ingredient?
Rated Good for reliably stabilizing silicone-in-water systems and delivering a silky glide with generally low irritation. It isn't rated higher because the benefits are mainly formulation-centric with limited direct, clinically substantiated skin improvement.
