When skin is damaged by UV exposure two conditions can
occur: hyperpigmentation, and hypopigmentation. The first, hyperpigmentation,
is the occurance of dark “sunspots” that form as the body produces melanocytes
that absorb the UV radiation and prevent it from causing damage to the deeper
layers of skin. Hypopigmentation occurs after a trauma to the skin, and yes,
overexposure to sun counts as a trauma. Excess UV causes tiny “scars” on the
skin, and those patches lose the ability to produce melanin, and the visible
effect is white spots on the skin. These are typically surrounded by
hyperpigmentation spots, and that is how you know these spots are a result of
sun damage.
This condition is not dangerous or serious, but it is completely
irreversible. Once the spots form, there is no way medical or esthetic to
reverse the damage. The best way to treat is to prevent further damage by
properly using sunscreen.
That being said, there are three ways to “mask” the damage.
- The first is the application of self tanners. Self
tanners will, temporarily, dye the skin cells and cover the hypopigmentation. You
can have these products applied professionally, or you can do it yourself at
home (but be careful, watch for streaking!)
- The second is the application of permanent makeup to
cover the damaged areas with pigment. The permanent makeup artist will match
the color to your skin tone, and usually the damaged area is completely
neutralized by the application.
- By using microdermabrasion and chemical peels to
neutralize the hyperpigmentation (dark spots) you can see an improvement in
skin tone, as the lighter patches do not stand out as noticeably.
Lastly, these solutions apply to hypopigmentation spots
caused by sun damage; there are several other causes for hypopigmentation, so
it is best to consult a medical professional to rule out the following
conditions:
Vitiligo:
Vitiligo causes smooth, white patches on the skin. In some people, these
patches can appear all over the body. It is an autoimmune disorder in which the
pigment-producing cells are damaged. Symptoms of vitiligo include an often
rapid pigment loss in several areas of the skin, and it is more common in dark
skinned individuals.
Tinea Versicolor:
Tinea versicolor is caused by a fungus. This fungus lives all around us,
including on the skin. Symptoms of tinea versicolor include small, flat, round
or oval spots that may, over time, form patches. The spots occur on oily areas
of skin on the upper chest, back, or upper arms or, less often, on the upper
thighs, neck, or face. The
spots can be lighter or darker than the skin around
them. This condition can be very tricky to diagnose, so make sure you consult a
medical professional if you suspect you have Tinea Versicolor.
