MAC Studio Finish concealer is a cream concealer which provides full coverage. MAC SAs generally suggest this for those with heavy dark circles.
It contains SPF35 which is an advantage. It comes in a cute little tub packaging which is very handy and travel friendly.
Since it is a cream concealer, I mostly use my fingers or a flat eyeshadow/concealer brush for application. However, I feel it blends better with fingers.
As you can see, NC42 has strong yellow tones which neutralizes any darkness on both the lids and the under eyes.
If you are looking for an orange corrector, NC45 would do great.
Pros:1. Travel friendly 2. Available in many shades 3. Blends easily 4. Moisturizes dry under eye area 5. Provides full coverage Cons: 1. Creases after sometime on very oily skin so you need to set it with a good powder 2. Expensive
Rating: 4/5 Final Words: Great for those with dry skin, those who need heavy coverage
