Anyone considering a skin whitening treatment has probably encountered warning information about hydroquinone, a substance frequently found in prescription whitening products and some over-the-counter items that has been criticized for its potential ties to cancer. Banned in many countries with certain exceptions for medical treatments, hydroquinone doesn't have to be a source of worry for those who wish to lighten their complexions or treat uneven skin tones. Nature's broad collection of ingredients can be called upon to create effecting skin whitening treatments, and extract-based formulas are fast becoming a preferred choice for safer product use.
