My 18-year-old daughter said that pink beige would have been better. I think it would be good for me since it lightens dark spots.
I'm cool-toned. I was looking for a concealer that would suit my skin tone, and when I tried out the pink beige that looked best on me in the store, it was sold out, so I wanted to try a new concealer that everyone's talking about, so I bought the vanilla beige for highlighting. It's not drying, a little goes a long way, and the color is natural and easy to use. I'll also be buying the pink beige for coverage!
I think this is a matter of choosing the right shade, but I think the pink beige is best used as a highlighter. The texture felt a little hard. Next time, I'd like to try using a different shade as a concealer! However, if you apply the pink beige to your cheeks, it instantly brightens your skin and makes it look fairer!
It doesn't dry out quickly after application, so it's easy to spread! The color is just right, so I'm glad I bought it!
I used to love Dior concealer, but even after switching to this, I don't have to worry about creasing or anything like that.
