Skin bleaching (or lightening), has a long, deeply rooted history that extends beyond the act of using beauty products to lighten one's skin tone.
Skin lightening products have clinical uses that may be helpful in managing specific pigmentary disorders, such as
-
Melasma
-
post inflammatory hyperpigmentation
Dermatologists frequently use prescription products containing ingredients such as
-
hydroquinone
-
azeleic acid
-
kojic acid
These products should not be used with the goal of lightening one's natural skintone.
Melasma
Melasma is a pigmentary disorder in which irregular brown or blue gray patches form on the skin, most often the face.
It is most common in women with brown skin or skin that tans easily. It is also common during pregnancy.

Post Inflammatory Hyperpigmentation
Post inflammatory hyperpigmentation develops when the skin produces extra pigment after injury, irritation, or disease.
It is more common in melanin-rich skin and tends to be prominent and longer-lasting.

Misuse of Skin Lightening Products
Exogenous ochronosis is a condition that can result from misuse of topical hydroquinone, and is very difficult to treat.
It is characterized by blueish black patches on the skin.
These typically affect areas where hydroquinone is applied.
