Treatment for postinflammatory hyperpigmentation may include topical agents like hydroquinone, retinoids, ascorbic acid, and azelaic acid, as well as chemical peels or laser therapy to promote skin renewal and reduce pigmentation. Sun protection is also crucial to prevent further darkening of the affected skin.
Hypopigmented lesions can range in color from hypopigmentation to depigmentation, and their size, form, and primary inflammatory dermatosis frequently correspond with each other. Complete depigmentation is more noticeable in people with darker skin and is frequently observed in cases of discoid lupus erythematosus and severe atopic dermatitis .
There are a wide range of depigmenting treatments used for hyperpigmentation conditions, and responses to most are variable. [11]Most often treatment of hyperpigmentation caused by melanin overproduction (such as melasma, acne scarring, liver spots) includes the use of topical depigmenting agents, which vary in their efficacy and safety, as well as in prescription rules.
Often, hypopigmentation can be brought on by laser treatments; however, the hypopigmentation can be treated with other lasers or light sources. [6] Micropigmentation can also be used to obtain a more normal appearance of the hypopigmentated skin. [7] Treatment for hypopigmentation depends on the initial cause of the discoloration.
Phytophotodermatitis, also known as berloque dermatitis, [1] [2] [3] margarita photodermatitis, [4] [5] lime disease [6] or lime phytodermatitis [6] is a cutaneous phototoxic inflammatory reaction resulting from contact with a light-sensitizing botanical agent (such as lime juice) followed by exposure to ultraviolet A (UV-A) light (from the sun, for instance).
Because EDP is an uncommon disease of the skin, it is important to consider other skin diseases that may resemble erythema dyschromicum perstans, such as infectious diseases (i.e. leprosy or pinta), reaction to drugs, post inflammatory hyperpigmentation, or lichen planus pigmentosus.
APMPPE is classified as an inflammatory disorder that is usually bilateral and acute in onset but self-limiting. The lesions leave behind some pigmentation, but visual acuity eventually improves even without any treatment (providing scarring doesn't interfere with the optic nerve).
Discoid lupus erythematosus is the most common type of chronic cutaneous lupus (CCLE), an autoimmune skin condition on the lupus erythematosus spectrum of illnesses. [1] [2] It presents with red, painful, inflamed and coin-shaped patches of skin with a scaly and crusty appearance, most often on the scalp, cheeks, and ears.
