Grip Trip Mattifying + Blurring Primer

Both share niacinamide and a hydrating base, but Fenty's mattifying/blurring effect comes from silica, lauroyl lysine, and multiple gripping polymers that e.l.f.'s formula lacks entirely - this is a hydrating grip primer, not a mattifying one.

Fenty's primer relies on a silica/polymer blurring matrix with lauroyl lysine and multiple film-forming polymers for grip and mattifying, while this L'Oreal version is a clay-based (magnesium aluminum silicate) primer with different polymers - only trivial pH-adjuster overlap like citric acid.

This IT Cosmetics primer uses dimethicone and different acrylate/taurate polymers plus salicylic acid for a silicone-based smoothing effect, sharing only trace tocopherol with Fenty's silica-and-polymer mattifying system.

Milk's Hydro Grip is a minimalist hydrating gel primer with niacinamide and hyaluronic acid, missing all the silica, alkanes, and acrylate polymers that give Fenty its mattifying and blurring effect.

Deliplus is a glow/hydration-focused primer with seaweed extract, betaine, and retinyl palmitate, sharing only minor citric/lactic acid overlap with Fenty's mattifying silica-and-polymer formula - no shared actives for grip or blur.
