I bought it because it's popular on social media. I'm well aware that it's a bit too flashy for my age, but it was so cute I had to buy it. Number 12 is glittery! When I use it, the glitter sparkles and it shines pale blue. On my cheeks. I thought that using too much might be too much, so I just put a little on the highest point of my cheeks. It's cute. I use it when doing summer makeup for my cool undertones, and it adds a translucent look that lifts my spirits. Also, it looks so cute that just looking at it gets me excited. I want the others too. If I were to buy one, I'd probably go for number 1, 4, or 5. I use a highlighting brush I bought from fwee to apply it. It's easy to use, so I recommend it.
