Hydroquinone is one of the most misunderstood ingredients in skincare. This organic compound, found in blueberries, cranberries and other fruits and vegetables, is the only FDA-approved way to lighten skin discolorations.
And while it is available over-the-counter or with a prescription from your doctor, don’t book an appointment with your dermatologist just yet. The 4% by-prescription-only variety can be more irritating than the two percent found in OTC products, without guaranteeing better results. We find that 2% hydroquinone works extremely well when combined with exfoliation and sun protection.
