Ideally, a skin lightening cream should not be used for longer than eight to twelve weeks at a time. That is the opinion of several different skincare experts. This amount of time is sufficient for the product to lighten the skin without the risk of causing any type of damage.

These products can be very effective in lightening the skin on the condition that you take some precautions while using them for example you do not expose yourself to the sun, and you avoid anything that might cause darker spots to occur. It is important to avoid exposure to the sun because the ultraviolet rays of the sun cause more melanocytes that result in darkening the skin which is going to defeat the purpose.
People who have a skin condition such as melasma may use a skin bleaching product as well. Melasma is a skin condition that is characterized by a dark spot on the skin and is fairly common in pregnant women or those on birth control pills.
Of course, a skin-lightening cream may not be the best way to combat a problem such as an age spot because it is all but impossible to ensure that the cream is only placed on the spot and does not come into contact with the skin around it.
This is why using the product without the supervision of a qualified dermatologist is not advisable. When you do use it under the care of a professional you will be able to minimize the risks and side effects.
