Precautions while using Bleaching
Hydroquinone side effects
Hydroquinone is the only skin bleaching chemical recognized by the FDA. Skin bleaching creams may have different percentages of Hydroquinone in their compound, but any skin bleaching cream with over 2Percent may cause side effects. The most common side effect of skin bleaching is skin irritation and a burning sensation. The itching or stinging of the skin should be mild and temporary, with some reddening of skin where cream is applied.
