Another important but often ignored reason why your face is getting darker without sun is indoor and artificial light exposure. Blue light emitted from mobile phones, laptops, televisions, and LED lighting penetrates the skin and creates oxidative stress. Research suggests that prolonged blue light exposure can stimulate melanin production, especially in medium to darker skin tones. Spending long hours in front of screens without proper skin protection may gradually cause facial darkening, particularly on the cheeks and forehead.

Environmental pollution is a significant contributor to why is my face getting darker without sun. Even if you stay indoors, pollutants such as dust, smoke, chemicals, and airborne toxins settle on the skin. These pollutants generate free radicals that damage skin cells and accelerate aging. In response, the skin increases melanin production to protect itself, leading to pigmentation, dullness, and uneven facial tone. Urban living, traffic exposure, and poor air quality can significantly impact skin color over time.
