When those pathways become inefficient—due to diet, stress, sleep disruption, or aging—glucose handling becomes less stable. Insulin resistance may increase. Lipid profiles may drift.
Dark spots rarely appear without cause. They follow inflammation. They follow sun exposure. They follow barrier disruption. What people casually call “discoloration” usually falls into a few biological categories: post-inflammatory hyperpigmentation (PIH), melasma, or uneven melanin distribution after repeated irritation. These are not simply “surface stains.” They’re regulated responses—
Post-inflammatory hyperpigmentation (PIH) is one of the most common skin concerns following acne, irritation, or minor injury. These marks are flat, smooth, and often brown or grayish in tone. Unlike scars, they do not represent structural damage to the skin. Instead, they reflect a temporary increase in melanin production triggered
