Yellow skin around the mouth is most often caused by carotenemia, a harmless buildup of pigment from foods rich in beta-carotene. The area around the nose and mouth (the nasolabial folds) is one of the first places this discoloration shows up. Less commonly, the yellowing can signal a liver problem, a thyroid condition, or simply be staining from a skincare product. The key to figuring out which applies to you is knowing what other signs to look for.
Carotenemia: The Most Common Cause
Carotenemia is a condition where beta-carotene, the orange-yellow pigment in many fruits and vegetables, accumulates in your skin. It was first described in 1904 and has a very specific pattern: the yellow-orange color concentrates on the palms, soles of the feet, forehead, tip of the nose, and the creases beside the mouth. Eating more than about 30 mg of carotene a day over a prolonged period can trigger it.
That threshold is easier to hit than you might think. Carrots, sweet potatoes, pumpkin, squash, kale, spinach, and mango are all high in beta-carotene. So are less obvious foods like butter, eggs, and palm oil. If you’ve recently started eating more of these, or if you’re on a diet heavy in smoothies, juices, or plant-based meals, carotenemia is the most likely explanation for the color change around your mouth.
Carotenemia is completely benign. It doesn’t damage your organs or indicate disease on its own. Once you reduce your intake of carotene-rich foods, blood levels of carotene drop within about a week, but the yellow color in your skin fades more slowly, over several weeks to months. That’s because carotenoids are fat-soluble and linger in tissue long after blood levels normalize.
How to Tell It Apart From Jaundice
This is the distinction that matters most. Jaundice is yellowing caused by a buildup of bilirubin, a waste product your liver normally processes. It can signal liver disease, bile duct problems, or other serious conditions. Carotenemia and jaundice can look similar on the skin, but there’s one reliable way to tell them apart: check your eyes.
In jaundice, the whites of your eyes turn yellow. In carotenemia, they stay white. Carotenemia also spares the inside of your mouth and other mucous membranes. If the yellowing is limited to your skin, particularly the palms, soles, and face, and your eyes look normal, jaundice is unlikely.
If your eyes are yellow, or if the skin discoloration comes with dark urine, pale stools, abdominal pain (especially on the upper right side), fever, fatigue, unexplained weight loss, or itching, those are signs of a liver or bile duct problem that needs medical attention promptly.
Other Medical Conditions That Cause Yellow Skin
Several conditions beyond diet can produce yellow skin, and some of them concentrate the discoloration in visible areas like the face.
- Hypothyroidism. An underactive thyroid slows the conversion of beta-carotene into vitamin A, letting carotene build up in the blood even at normal dietary levels. If you also have fatigue, weight gain, dry skin, or feeling cold all the time, thyroid function is worth checking.
- Diabetes. Yellow skin discoloration has been documented in people with diabetes, again linked to altered carotene metabolism. It tends to appear on the palms and soles but can affect the face as well.
- Kidney disease. Impaired kidney function can contribute to yellowish skin tones, though this typically comes with other noticeable symptoms like swelling, changes in urination, or fatigue.
In all of these cases, the yellowing is a secondary sign alongside other, more prominent symptoms. If you feel generally well and the yellowing is your only concern, a systemic condition is less likely.
Skincare Products That Stain the Skin
Before assuming something internal is going on, consider what you’re putting on your face. Topical vitamin C serums, one of the most popular anti-aging ingredients, can leave a yellow to yellow-brown tint on the skin. This happens because the active form of vitamin C (ascorbic acid) breaks down into compounds that have a visible yellow-brown pigment. The staining is cosmetic and washes away over time once you stop using the product or switch formulations.
Turmeric-based masks or creams can also leave a temporary yellow residue, especially in the creases around the mouth where product tends to settle. If you’ve recently added a new serum, moisturizer, or mask to your routine, try stopping it for a week or two to see if the color fades.
Seborrheic Dermatitis and Flaky Yellow Patches
If the yellow color around your mouth comes with flaking, scaling, or greasiness, seborrheic dermatitis is a possibility. This common inflammatory skin condition produces white to yellowish scales on oily areas of the face, including the creases beside the nose and the area around the lips. The “yellow” in this case isn’t a change in your actual skin tone but rather yellowish, oily, sticky flakes sitting on the surface.
Seborrheic dermatitis tends to come and go and often gets worse with stress, cold weather, or infrequent face washing. It’s not dangerous, but it can be persistent. Over-the-counter antifungal cleansers designed for the face usually help control it.
Pallor That Looks Yellow
Sometimes what looks like yellowish skin is actually pallor, a loss of your normal skin color that can give the face a sallow, washed-out, or slightly yellow-gray appearance. Pallor is especially noticeable on the face and around the mouth, and it’s caused by reduced blood flow to the skin or a drop in red blood cells.
Iron deficiency anemia, vitamin B12 deficiency, and folate deficiency can all cause this. You might also notice that the inside of your lower eyelids looks pale when you pull them down, or that your nail beds have lost their usual pinkness. Fatigue, dizziness, and shortness of breath with exertion are other common signs. A simple blood test can confirm or rule out anemia.
What to Do Next
Start with the simplest explanations. Look at your diet over the past few weeks and your skincare routine. Check whether the whites of your eyes are still white, which is the single most useful thing you can do at home to separate a harmless cause from a potentially serious one.
If the yellowing appeared suddenly, spreads beyond your face, involves your eyes, or comes with any of the warning signs mentioned above (dark urine, abdominal pain, fever, unexplained weight loss), get bloodwork done. A basic metabolic panel and liver function test can quickly clarify whether something systemic is going on. For most people, though, the answer turns out to be an extra serving of sweet potatoes.
