The Revlon is just a pinch darker. They both have the same fine glitter in them and they are both very pigmented on the lips.
The first swatch is the Dior (left)
and the other swatch (right) is Revlon.
Looking for a great quality light redish lipgloss for half the price of a high end one? Defiantly check out the Revlon at your local drug store.
