For your freckles use sunscreens every 4 hourly to avoid further increase.
You can do phenol peels to reduce the pigmentation.
Use lot of mositurisers ( cetaphil
or dermadew or any other brand ) and avoid harsh soaps( there are medicated mild soaps available) and very hot water.
Please see a dermatologist
