What is pigmentation?
Skin pigmentation and sunspots is the body’s natural defense against sun damage and is a normal function of a healthy skin. Pigment in our skin comes from a substance called melanin. Hyper pigmentation refers to abnormal darkening of the skin due to increased production of melanin, the pigment that gives skin its color. The problem can appear in small patches or involve larger areas of the skin. These darkened areas can be challenging to conceal with regular cosmetics. What causes this condition and what can you do about it? Hyper-pigmentation (hyper = too much, over supply) occurs when the skin is stimulated through trauma, environmental damage or hormone imbalance which results in uneven skin tone or patchy brown marks on the skin.
What Causes Excessive Pigmentation of the Skin?
Most frequently areas of abnormal pigmentation are due to sun damage or injury to the skin. Darkly pigmented areas called solar lentigines or age spots are very common on the hands and face. They are caused by damage due to sun exposure. Some medical conditions can contribute as can certain medications. Exposure to toxins or chemicals can also play a role. The hormonal changes associated with pregnancy and oral contraceptives can also cause temporary, patchy pigmentation of the skin. It is also very common for people with acne to experience persistent red or purple marks on the skin after acne lesions heal. This is more prevalent among people who pick at their blemishes.
It is also typical to see areas of increased pigment with other skin conditions such as psoriasis, pityriasis rosea, lichen planus and atopic dermatitis. These skin diseases cause inflammation, which stimulates melanin-producing cells called melanocytes to secrete more melanin. Inflammation can cause skin cells called melanocytes to produce too much pigment.
Hyperpigmentation occurs more frequently in people with skin that is darkly pigmented. There is a skin condition called melasma that occurs more often in those with deeper skin tones. The condition causes dark patches to form on the face, especially on sun-exposed areas.
Exposure to sunlight is the major cause of hyper-pigmentation and will darken an already pigmented area. It is vital to wear a minimum of SPF30 with UVA and UVB protection for these skin types or any professional skin treatments will be rendered ineffective.
