What causes the bright rays on the Moon's surface to become duller?

Moon's matte surface that makes it less reflective and the variation in the amount of sunlight received by the Moon at the edges.

The key reason for the bright rays on the Moon's surface becoming duller is the matte surface of the moon which does not allow the rays to reflect properly and appear brighter.
