We should take care of Hydroquinone in some products

First of all,let me tell you what is Hydroquinone. Hydroquinone, also benzene-1,4-diol or quinol, is an aromatic organic compound that is a type of phenol, having the chemical formula C6H4(OH)2,getting the CAS NO: 123-31-9 . Its chemical structure is not complicate, two hydroxyl groups bonded to a benzene ring in a para position. It is a white granular solid. Substituted derivatives of this parent compound are also referred to as hydroquinones.

In human medicine, hydroquinone is used as a topical application in skin whitening to reduce the color of skin. It does not have the same predisposition to cause dermatitis as metol does. This use is banned in some countries, including the member states of the European Union .under Directive 76/768/EEC:1976.
Regular use of hydroquinone can cause serious irritation of the skin, especially for people that already have sensitive skin or allergies. 
In some cases, hydroquinone can cause extreme redness, itching or even a burning sensation when it is applied to the skin.

Although Hydroquinone is not suitable for every patient who is suffering with skin disease, especially healthy people, Hydroquinone usually used in many daily use products. You may think I had never contract with Hydroquinone, but Hydroquinone isn’t used on its own–meaning you won’t get a prescription or buy an over-the-counter product called hydroquinone. In fact, hydroquinone usually only makes up a small percentage of the topical product it is used in.

Many of the other ingredients used in products that contain hydroquinone can also cause skin irritation and damage the skin, especially combined with hydroquinone. Even small amounts of hydroquinone can increase your chances of a negative reaction to other ingredients within a skin lightening product.

Hydroquinone works to reduce the amount of melanin your skin produces, which in turn makes your skin lighter in appearance however, doing this makes your skin more susceptible to UVA and UVB rays that can lead to dangerous sunburns, and over a prolonged period of time, an increased risk of certain types of skin cancer. Hydroquinone also makes your skin more susceptible to sun damage, much the same way topical treatments like salicylic acid do.

Most manufacturers tell users to limit their sun exposure when using hydroquinone treatments, but many people use them for a considerable amount of time, and few people are willing to avoid the outdoors completely. Some people are surprised by how bad severe a sunburn can be or how irritated their skin becomes because of prolonged sun exposure when using topical products that contain hydroquinone.

Hydroquinone is not a bad thing, we should use it in a right way. As a consumer what we should do is that taking a care of the products which is combination with Hydroquinone.
