I'm new to concealers. I've always used foundation, but I always found it annoying to apply it all over my face, so I decided to give this product a try. It's inexpensive, highly rated, and seemed easy to use. It was a great choice. One coat only makes blemishes faint, but applying multiple coats really helps to conceal them. It also covered the redness from acne scars. (It didn't cover the large dark circles under my eyes, though...) I apply a moisturizing primer first, so it doesn't dry out my skin. It lasts all day, even when I'm wearing a mask. I use a very small amount, so I'm not sure when I'll need to buy more, but I plan to buy it again.
