This is MAC Studio Fix 24-Hour Smooth Wear Concealer, and it’s best suited for:
Oily skin – helps control shine and stays put
Combination skin – especially in oily areas like under the eyes, nose, and chin
Normal skin – gives a smooth, long-lasting finish
Because it has a long-wear, matte-leaning formula, it can also work for dry skin if you prep well with a hydrating eye cream or moisturizer first.
Overall, it’s designed to perform best on normal to oily and combination skin types, with strong staying power and minimal creasing.
