Is Topical Hydroquinone Safe for Skin Lightening?

Hydroquinone based skin lightening creams are the mainstay of effective skin brightening when used properly. I use a brightening kit from Kare Skin. See link below. It contains a regimen that is quite effective. 

Although slightly controversial, hydroquinone
is safe and has been used as a skin lightening agent for nearly 20 years. Of
course it’s not to be used during pregnancy, while nursing or when trying to
conceive. There are issues with continuous usage at high doses, but tapered
dosage with optimum sun-protection provides effective control of
hyper-pigmentation. Your doctor of course needs to be told of any medical
conditions, especially those pertaining to the kidney or liver, so that he or
she can advise you accordingly.
