Many people develop brown spots on their skin over time, especially if they’ve had a trauma to their skin or spent much time in the sun. The term for these spots is hyperpigmentation, which describes an excess of pigment in the skin. Often an early sign of aging, they may first appear on the backs of hands. These spots can be faded, but patience for the process is required because repeated treatments will be necessary. It takes regular use of sunscreen to keep hyperpigmentation from returning. (Note that hyperpigmentation is different from hypopigmentation, which appears as lighter spots on the skin).
Hyperpigmentation arises when melanin in the epidermis becomes irritated, so to speak, and increases production, darkening the outer skin and becoming visible at the skin’s surface. Regularly scheduled professional treatments, combined with a proper home care regimen, can calm the production of melanin and lighten the skin.
Hyperpigmentation takes different forms. These include:
Freckles/lentigenes.These are the result of an inherited tendency; exposure to the sun will darken their color.
Solar lentigenes.These darkened spots on the skin that some call age spots indicate overexposure to the sun that has resulted in ultraviolet light damage.
Melasma.Melasma is a response to hormone changes, such as those caused by birth control pills, pregnancy, and menopause, resulting in facial spots.
Postinflammatory hyperpigmentation.This is the direct result of an injury to the skin. The body’s response to injury is inflammation. Some think this inflammation reprograms melanocytes to be hyperactive and to produce more melanin. It affects men and women equally. Some common pigmentation- causing injuries include: abrasions, cuts, and wounds; acne lesions and cysts, excoriations (picking pimples); aggressive chemical exfoliation (peels); aggressive extraction; ingrown hairs; insect bites; scratching; sunburn; and waxing.
There is another type of hyper- pigmentation that is more diffused and appears as an overall darkening of the skin, rather than in patches and spots. This condition should be cared for by a dermatologist, as it may reflect a disease or systemic problem, like Addison’s disease or scleroderma.)
Hyperpigmentation can be caused by certain prescription drugs, like antibiotics, antidepressants, barbiturates (depressants), and chemotherapy drugs. Some over-the-counter laxatives with phenolphthalein and nonsteroidal anti-inflammatory drugs (NSAIDs), like ibuprofen, can cause hyper- pigmentation. Be sure to record your use of these drugs on the intake form (or on an updated health history) when you arrive and verbally mention them to your esthetician before beginning a treatment.
Occasionally, people mistake darkness under the eyes for hyperpigmentation, but this condition is a reflection of the blood vessels through the surface of the skin. These circles have a variety of causes and can sometimes be treated with peptides.
While hyperpigmentation generally affects all races, some forms of it appear more often with certain skin colors and tones. For example, melasma and postinflammatory hyperpigmentation are more prevalent in darker skin. Solar lentigenes are more prevalent in lighter skin (ninety percent of white adults older than 60 have age spots); they also are more common in women than men.
