MAC Cosmetics Studio Fix Fluid SPF 15 24HR Matte Foundation + Oil Control dupe

Revlon ColorStay Longwear Makeup for Combination/Oily Skin at about $12.48. Both are matte, long-wear water-in-silicone foundations with SPF 15, set by the same resin, trimethylsiloxysilicate, and 16 of MAC's ingredients are in ColorStay's list, salicylic acid, sodium hyaluronate and the same dimethicone/PEG-10/15 crosspolymer among them.

Studio Fix Fluid SPF 15 24HR Matte Foundation + Oil Control costs about $39 for 30 ml, or $38.45 / fl oz. Revlon ColorStay Longwear Makeup for Combination/Oily Skin works out at $12.30 / fl oz, roughly 68% less per ounce.

Studio Fix Fluid SPF 15 24HR Matte Foundation + Oil Control costs about $39 for 30 ml, about 3.1 times as much per ounce as Revlon ColorStay Longwear Makeup for Combination/Oily Skin. The trade-off with Revlon: MAC's sunscreen is octinoxate with titanium dioxide and its slip comes from isododecane and methyl trimethicone, where Revlon uses titanium dioxide with zinc oxide in cyclopentasiloxane, adds nylon-12 for a softer blur, and splits its shades between a combination/oily and a normal/dry formula. If that doesn't matter to you, the original isn't worth the extra $27.
