Skin pigmentation could come about for various reasons, some which can be avoided and some which are unavidable like sunlight. sunlight is good for our bodies and skin but again too much of it can cause trouble. There is pigmentation that can be treated without creams depending on what caused it in the first place. you cannot start treating pigmentation that has been caused by someone trying to bleach themselves, that is actually permanent there is not much that can be done. but if it is acne, there are many ways . like using apple cider that has the mother, you can cleanse your face with it then use not very harsh moisturisers, use mild ones like vaseline for example that's the best especially for delicate skin. then you can also use lemon, tumeric and sandal wood powder mixed together with some lemon. apply throughout the face leave on for 20 min then rinse off with warm water do this repeatedly and thank me later.
