Precautions
Hydroquinone may produce exogenous ochronosis, a gradual blue-black darkening of the skin. If this condition occurs, discontinue treatment. Test for skin sensitivity before using by applying a small amount to an unbroken patch of skin; check within 24 hours. Minor redness is not a contraindication, but where there is itching or vesicle formation or excessive inflammatory response, further treatment is not advised. Close patient supervision is recommended.
After clearing and during maintenance therapy, sun exposure should be avoided on bleached skin by application of a sunscreen or sunblock agent or protective clothing to prevent repigmentation. Avoid contact with eyes and mucous membranes.

Adverse Effects
Side effects of Octinoxate + Oxybenzone+ Hydroquinone + Zinc oxide topical :
The following adverse reactions have been reported: dryness and fissuring of paranasal and infraorbital areas, erythema, and stinging. Occasional hypersensitivity (localized contact dermatitis) may develop.
Mechanism of Action
Topical application of hydroquinone produces a reversible depigmentation of the skin by the inhibition of the enzymatic oxidation of tyrosine to 3, 4-dihydroxyphenylalanine (DOPA) and suppression of other melanocyte metabolic processes. Exposure to sunlight or ultraviolet light will cause repigmentation of the bleached areas
