ExplainerHyperpigmentation causes, and why the same triggers can leave skin lighter instead
Most lists of hyperpigmentation causes stop at sun, hormones and acne marks. The part they leave out is that several of those same triggers, from a rash to a laser to a bleaching cream, can just as easily leave a white patch, and what decides the direction is whether the pigment cells survive the hit.

ExplainerCan pigmentation go away? Which white patches fade on their own, and which stay
Whether lost pigmentation can go away depends on one question nobody asks out loud at the first visit: are the pigment cells still there? Pale skin from a rash or a yeast usually refills in weeks to months, while the porcelain dots on aging shins essentially never do, and even vitiligo quietly repigments by itself in about one patient in five.

ExplainerHypomelanosis explained: progressive macular hypomelanosis, the pale trunk patches that keep getting treated as fungus
Hypomelanosis simply means less melanin than normal, but the version most adults actually search for is progressive macular hypomelanosis: soft pale patches on the back and belly that are routinely prescribed antifungals that cannot work. The entire controlled evidence base for treating it fits in fewer than 90 patients.

ExplainerWhy Vitiligo Repigments in Dots: The Follicular Reservoir Explained
Those freckle-like specks inside a treated patch are not random. They map directly onto hair follicles, and understanding why explains which areas respond to therapy and which resist it.

ExplainerNot Every White Patch Is Vitiligo: How Clinicians Separate True Depigmentation From Its Four Most Common Mimics
Pityriasis alba, tinea versicolor, post-inflammatory hypopigmentation, and idiopathic guttate hypomelanosis are misread as vitiligo every day. Here is the mechanism-level logic dermatologists use to tell them apart, and why the distinction changes treatment.

ExplainerWhy Repigmentation in Vitiligo So Often Starts at the Hair Follicle
The freckle-like dots that appear inside a treated vitiligo patch are not random. They trace back to a reservoir of dormant pigment cells hiding in the hair root, and understanding that reservoir explains which patches respond to treatment and which rarely do.

ExplainerThe Wood's Lamp, Explained: Why a 1903 Invention Still Settles Modern Vitiligo Questions
Before biopsies, blood panels, or advanced imaging, most dermatologists reach for a handheld ultraviolet lamp. Here is what it actually shows, what it cannot show, and why the distinction between hypopigmentation and depigmentation matters for treatment.

ExplainerWhy Vitiligo Repigmentation So Often Starts as Tiny Dots Around Hairs
The freckled, perifollicular pattern that appears during successful treatment is not random. It reflects where the skin keeps its reserve melanocytes, and it explains why some patches respond and others resist.

ExplainerWhy Vitiligo Repigments From the Hair Follicle Outward, and What That Means for Your Treatment Timeline
The freckle-like dots that appear inside a treated vitiligo patch are not a side effect. They are the treatment working. Here is the biology behind perifollicular repigmentation and how to read your own progress.

ExplainerHypopigmented or Depigmented? Why That One Word Changes Everything About a White Patch
The difference between lighter skin and skin with no pigment at all is the single most useful clue in sorting vitiligo from its common look-alikes. Here is how clinicians actually make the call.

ExplainerVitiligo beyond the skin: the melanocytes in your eyes and ears
Pigment cells are not exclusive to skin. They also sit in the inner ear and in several layers of the eye, and two large bodies of evidence disagree about how often that matters, which is exactly the thing patients are never told.

ExplainerWhite hairs inside a vitiligo patch: the sign that quietly predicts how well it will repigment
Nobody hands you a prognosis at diagnosis. But the hairs growing out of the patch carry one, and you can read it yourself in a well-lit bathroom in about two minutes.
