Skin Getting Darker Skincare mistakes are another common reason behind skin getting darker. Not using sunscreen daily is one of the biggest contributors to pigmentation problems. Many people assume sunscreen is only necessary on sunny days or during outdoor activities, but UVA rays penetrate clouds and glass, affecting the skin even indoors. Over-exfoliation damages the skin barrier and causes irritation, triggering increased melanin production. Using harsh soaps, strong acids, bleaching creams, or unsafe home remedies like lemon juice can increase skin sensitivity and lead to further darkening rather than improvement. http://sknlex.com
