After yag laser treatment - darker color. (photo)

Three weeks ago I had yag laser treatment for the brown spots on my face. After 5 days , the brown patch flaked off . Then it becomes pink color patch . Now three weeks later, the pink patch turns to more darker color than before . When you touch the treatment area, skin is soft and smooth . I use sunscreen after the treatment everyday . what should I do ? It s really annoying and the concealer can't cover it . Please help !! The photo showed after the concealer.
