Skin colour is something that you get genetically. The only thing that can be achieved is an even skin tone which can then lead to lightening of skin tone and healthier looking skin.
You cannot use skinlite
cream for more than there weeks. Its harmful to the skin.
You need to use sunscreen daily to prevent tanning
due to sun exposure.
For skin lightening you need to visit your dermatologist
who can evaluate the treatment that you would need to have a better skin tone and to treat a tan if any.
