A lot of people in the youtube beauty community have compared Revlon colorstay to mac studio fix fluid. Ive used both, infact mac studio fix fluid is probably my favorite foundation. There are similarities between the two but I would say that the Revlon color stay is a bit more smooth to apply and wears beautifully. Although the studio fix lasts a bit longer and covers a lit bit more with less product. Also Mac has more shades to choose from.
