This concealer really does last a very long time. On the packaging it says it should last 15 hours. I wouldn’t know since I only wear makeup for a maximum of 8 hours. But it lasted all day without any touch ups, which is great because I don’t like having to bother touching up during the day.
The concealer does not leave a cakey finish if you apply the right amount of it (which is very little). I accidently applied too much when I first started using it and it looked cakey and unflattering. So if you consider to buy this product, use only a little of the product. You can use a small fluffy brush like MAC 217 to apply it, or use your fingers (make sure they’re clean). I prefer using my fingers because the concealer blends more easily with the warmth of your hands.
