Brown spots on the face !

Hello ladies ,

During pregnancy i got brown un even spots on my face/ cheeks. Now my baby is 7 months but it is still there i have been using vitamin C serum and brown spot serum by Kheils but it is not going. I am so worried and not happy with my face i feel like i lost all my bright and glowing skin and will never ge back. Please share if you have been through this and got back to your normal skin tone and how long it took ? Will i be back to my normal skin ever again ??? 🙁
