Skin concerns
Why is my skin two different shades?
Face and body rarely match, and that is normal. Patchy two-tone skin on the trunk and arms is often a treatable yeast overgrowth people mistake for pigment.

Quick answer
The bottom line
Work out the pattern before buying anything to even it out. A face darker or lighter than the body is usually cumulative sun exposure and needs sun protection rather than fading products. Patchy lighter or darker areas scattered over the chest, back and upper arms, sometimes faintly scaly, are commonly a yeast overgrowth that antifungal treatment clears in weeks, though the colour lags behind. Sharply bordered milk-white patches, a brown mask across the cheeks and marks left after spots each behave differently. Get a look at anything you cannot place.

Three things worth remembering
Section 01
When the face and body do not match
The face receives far more ultraviolet exposure over a lifetime than the trunk, so it darkens more, weathers more and holds pigment differently. A mismatch between face and covered skin is the expected outcome of that difference, not a fault in either. It is most obvious in summer and after any holiday.[6][2]
The lever that works here is protection: daily broad-spectrum sunscreen on the face and neck, plus shade and clothing. Trying to lighten the face to match covered skin means fighting daily exposure with a cream, which is why people find the result never holds.[6]
Section 02
The cause people miss: a yeast overgrowth
Tinea versicolor is an overgrowth of a yeast that lives normally on skin. It produces patches that are lighter or darker than surrounding skin, often faintly scaly if scratched, scattered across the chest, back, shoulders and upper arms. It shows up most in warm, humid weather and in people who sweat a lot, and it is not an infection caught from anyone.[1]
This is the diagnosis behind a great many searches for two-tone skin, and it matters because it is cheap and quick to treat. Antifungal shampoos containing ketoconazole or selenium sulfide, left on the affected skin for the time the label states, clear the overgrowth in a few weeks. The colour difference fades afterwards over months, which trips people into thinking it did not work.[5][1]
Section 03
The other patterns, and how they differ
Melasma is a brown or grey-brown patterning across the cheeks, forehead and upper lip, usually symmetrical, driven by sun and hormones. Vitiligo produces sharply edged patches with no pigment at all, often around the eyes, mouth, hands and body openings, and is an immune condition rather than a fungal or sun one.[2][3]
Marks left behind after spots, eczema, an ingrown hair or a burn sit exactly where the earlier problem was and fade slowly on their own. They are the most common reason for uneven tone in deeper skin tones, and the most important step is settling whatever caused the inflammation, since new marks form faster than old ones fade.[4]
Section 04
A sensible order to work through it
Start with where it is. Scattered patches on the trunk and upper arms in warm weather point to the yeast, and an antifungal shampoo is a reasonable and inexpensive first test. Symmetrical patterning on the face points toward melasma and needs sun protection plus a proper plan. Marks that trace old spots need the cause treated first.[1][2]
Daily broad-spectrum sunscreen sits under all of them, because ultraviolet exposure darkens existing pigment and widens the contrast whatever the underlying cause. Skipping it is what makes every other measure look ineffective.[6][4]
Section 05
When to have someone look
Patches with no pigment at all and clean borders, anything spreading quickly, or patches that itch, hurt, thicken or bleed should be examined rather than treated from a shelf. A single new dark spot with an irregular edge that changes deserves prompt attention.[3][2]
It is also worth asking if a trial of antifungal treatment changes nothing after a month. Several of these conditions look similar in photographs and quite distinct in person, and naming the right one saves buying products aimed at the wrong process.[1][4]
