the sources of hyperpigmentation
These sources of hyperpigmentation are among the most common, and fortunately, the most treatable when under the care of a professional.
source 1: sun damage
While pigmentation has many sources, ultraviolet light from the sun is the most common cause of pigmentation disorders. However, pigmentation caused by sun damage is most easily prevented and is the most easily treated.
The normal response to daylight exposure (UV radiation from the sun) or tanning beds is an increase in melanin production, which causes uniform tanning in most persons but leads to freckling in some.
Sun damage can also contribute to Solar Lentigo and sun spots (age spots), which are also known as letigines. They form mostly on areas of the skin that are left unprotected from the sun, such as the hands and arms.
On the opposite spectrum of hyperpigmentation is hypopigmentation, which is the reduction or loss of pigment. Vitiligo is an immune disorder in which pigment-producing cells are damaged, which causes smooth, white patches on the skin that can appear anywhere on the body. To date, there is no cure for vitiligo.
source 2: medication
Medications are a frequent cause of sudden skin pigmentation. Most of the pigmentation is seen in sun-exposed areas, suggesting an interaction between ultraviolet light and ingested medication. Some known medications that can cause skin pigmentation include oral contraceptives, anti-seizure medications, anti-cancer medications, hypo-glycemic medications, non-steroidal medications, certain antibiotics, Accutane and Tetracycline.
Skin pigmentation caused by medication can be prevented by wearing sunscreen daily and applying it properly. See the section in this brochure titled Sun Protection as Your First Line of Defense for more information.
source 3: photosensitivity
Certain ingredients found in cosmetics and fragrances will create a photosensitive reaction, which is an abnormally heightened response to daylight or ultraviolet radiation. Some ingredients that can trigger this reaction are Oil of Bergamont which is found in fragrances, and Methylene Blue, Orange red, Erythrocine, Fluorescein and Methyl violet, which are found in cosmetics and dyes. Avoid any products that contain artificial fragrances or colors if you are currently experiencing hyperpigmentation.
source 4: hormones
Chloasma, also known as melasma or “the mask of pregnancy,” occurs when the sun-exposed skin on the upper cheeks, forehead, and/or upper lip turns a tan, brownish color because excess pigment is deposited in the skin’s upper layers. It can also show up when women take oral contraceptives. Men can also experience melasma, but it is rare. Scientists have found that men with melasma show low production of testosterone coupled with a higher level of LH (luteinizing hormone). when the sun-exposed skin on the upper cheeks, forehead, and/or upper lip turns a tan, brownish color because excess pigment is deposited in the skin’s upper layers. It can also show up when women take oral contraceptives; it can also be experienced by men. |
