Hi try with atrimed aclear cream for glow and removal of marks. It's a very good cream. Daily apply little on your face after washing it well and pat it dry at night before going to bed.
Also keep washing your face regularly at least once in 3 to 4 hrs. Use Himalaya neem face wash for the same.
For natural skin glow mash banana with cows milk and apply on the face as face mask and allow it to dry and then wash it off with water. It will give very good glow on the face.
Diet u have to eat already watery fruits, vegetables. Keep hydrated drink enough water. Bananas, oranges, lime, strawberries all these are good for skin. Also muskmelons, water melons.
