6 Reasons Why Sunscreen Is Essential, According to Dermatologists

Speaking of sun spots...

"Sun spots are those pesky brown spots that develop on sun exposed skin — primarily face, arms, chest, shoulders and back — and that occur after sun exposure from the stimulation of melanocytes, or pigment producing cells in the skin," explains Dr. Shari Marchbein, a NYC-based board certified dermatologist. "Melasma, also known as mask of pregnancy, is a form of hyperpigmentation characterized by brown patches on sun exposed areas, such as the cheeks, forehead, upper lip, and can occur less commonly off of the face on the scalp and arms."

Sun exposure exacerbates both of these issues — both of which are very difficult to treat — which makes preventative sunscreen application vital.
