Hydroquinone is a commonly used agent in skin whiteners. The European Union banned it from cosmetics in 2000. [9] It works by decreasing melanin production. [9] Tretinoin, also known as all-trans retinoic acid, may be used to whiten specific areas. [6] It may be used in combination with steroids and hydroquinone. [6]
Hydroquinone, also known as benzene-1,4-diol or quinol, is an aromatic organic compound that is a type of phenol, a derivative of benzene, having the chemical formula C 6 H 4 (OH) 2. It has two hydroxyl groups bonded to a benzene ring in a para position.
Monobenzone applied topically completely removes pigment in the long term and vigorous sun-safety must to be adhered to for life to avoid severe sun burn and melanomas.

[1] [2] It is used as a topical drug for medical depigmentation. [3] It is a colourless solid that is classified as the monobenzyl ether of hydroquinone.
Some photographers add a pinch of sodium sulfite before dissolving the metol to prevent oxidation, but large amounts of sulfite in solution will make the metol very slow to dissolve. Because metol is relatively toxic and can cause skin sensitisation, modern commercial developers often use phenidone or dimezone S (4-hydroxymethyl-4-methyl-1 ...
Hydroquinone is used to reduce the activated silver ions to metallic silver. During this process, hydroquinone is oxidized to quinone. All silver halide not activated by light or reduced by hydroquinone is removed, leaving a negative by deposited silver where the film had been struck by light. [18]
Arbutin is a compound where a glucose molecule, specifically d-glucose, is chemically bound to hydroquinone.In aqueous solutions, glucose can exist in one of three stereoisomeric forms: α, β, or γ, with the β-anomer being the predominant form. [4]
