How to get rid from pigmentation :- Pigmentation or hyperpigmentation, also known as dark spots, age spots, and sun spots, are uneven brown spots that appear on the face, arms, décolleté, and shoulders. These areas of discoloration, which are larger than freckles, age significantly.
What causes pigmentation?
Areas with uneven pigmentation are caused by sun exposure, in particular UVA rays that penetrate deep into the skin and cause aging.
Talking to Cosmopolitan Consultant Dermatologist Dr. Nick Lowe explained that “UVA stimulates pigment cells to produce a pigment called melanin. This causes sunburn as well as unwanted dark spots. "
Sun spots can take anywhere from 10 to 20 years to appear, he says, so even if you're struggling to protect your skin now, you may start noticing those that started as a child.
In addition to sun exposure, birth control pills and pregnancy can also cause pigmentation in young women, leading to new mottled dark spots.
