Overall Rating

Considered non-comedogenic, with little to no likelihood of clogging pores.

Is Dimethicone/bis-isobutyl PPG-20 Crosspolymer a Good Ingredient?

Good: An inert elastomer network that aids oil control and visual blurring with minimal irritation for most. Consistent texture improvement and stability warrant the rating.

Skin Benefits

Absorbs excess oil to reduce shine while softening the look of uneven texture. Leaves a cushiony, powdery touch for a refined, longer-wearing finish.

Uses in Skincare & Cosmetics

Found in pore-filling primers, shine-control gels, and transfer-resistant face or lip formulas to boost durability. Also used in mattifying sticks that smooth on without tackiness.

Safety

Typically well tolerated; very dry or compromised skin may experience temporary tightness. No common regulatory restrictions at standard cosmetic use levels.
