1. More birth control is being prescribed
Many doctors correlate the surge in hyperpigmentation to things like birth control and hormone replacement therapy. “The recent increase in birth control usage may be a reason for the rise in hyperpigmentation in women. The sudden shifts of hormones can cause hyperpigmentation to form,” says New York dermatologist Amy B. Lewis, MD.
2. Sunscreen still isn’t worn daily
Despite the fact that sun protection is necessary daily, not every American wears sunscreen every day of the year, which is another reason for the influx of skin discoloration. “The increased social and cultural trend of tanning is another reason why hyperpigmentation is on the rise,” says Minneapolis, MN, dermatologist Charles E. Crutchfield III, MD.
3. Some diseases can affect skin tone
One side effect of diabetes can be hyperpigmentation, especially on the neck. Older women who are diagnosed with diabetes often notice discoloration on this part of the body.
4. Population changes
Miami dermatologist Flor A. Mayoral, MD, notes that there are more people living in the U.S. than ever before with darker skin tone. “Hyperpigmentation is more likely to happen in those that have higher numbers of pigment-producing cells in their skin.”
