Hyperpigmentation (Brown Spots)
Hyperpigmentation, commonly experienced as brown spots or blotchy pigment, is caused by UV light which results in selective damage to some melanin-producing cells. Once hyperpigmentation is present, future UV light exposure causes damaged cells to produce more melanin pigment, forming darker brown spots. While there is no single cause, heredity appears to play a role. Other triggers include skin inflammation, pregnancy, and certain medications, including birth control pills and hormone therapy. To control the appearance of hyperpigmentation once present, it is essential to avoid triggers such as sun exposure and to use a combination of skin brighteners and exfoliation products.
