Dark shadow above my upper lip
You look in the mirror and see a faint brown band above your top lip. It can look like a smudge, or like a shadow that never lifts. Washing does not shift it, and makeup covers it for only a few hours.
The skin above the lip is one of the most common spots for melasma. Melasma means patches of extra brown color in the skin. The mark is often soft at the edges and shows up on both sides.
This mark is flat, not raised, and it does not itch or bleed. It tends to get darker in summer and fade a little in winter. It is a color change, not an illness in the rest of your body.
When to see someone
Book with a skin doctor within a week if the mark is on one side only. Do the same if it is raised, bleeds, crusts, or has a ragged edge.
Also go if it has more than one color, or if it has grown fast. These signs need a look in person.
See your usual doctor soon if your gums, palm lines, knuckles or old scars are going dark too. Go the same day if you also feel very tired, feel faint when you stand, or have lost weight. That mix can point to a gland problem that needs a blood test.
Make an appointment if your periods have stopped or gone odd. Do the same if you grow coarse dark hair on the chin, jaw or chest. A doctor can check your hormones.
Call the doctor who gave you a new medicine if the mark came on soon after you started it. Do not stop the drug on your own first.
Stop any product and get care the same day if the skin blisters, swells, or weeps. Rinse with plain water and go to urgent care if your lip or eye swells.
If you are pregnant or breastfeeding, ask your midwife or doctor before you use any cream or pill on this list.
Why it happens
Your skin has cells that make brown color. Their job is to soak up light and shield the skin below. In melasma, these cells switch on too much in one small patch.
Sun is the main trigger. The strip above the lip sticks out toward the sun and gets light most of the day. Even short daily trips add up over months.
Heat plays a part too, not just light. Hot stoves, hot cars and hot weather can make the patch darker. Some people flare after a sauna or a long walk in the heat.
Hormones are the second big driver. Pregnancy, the pill, the patch, the ring and hormone therapy can all set it off. That is why it shows up so often in women aged 20 to 50.
Rubbing matters as well. Waxing, threading, hard scrubbing and stinging products can stir up the skin. Once that strip is upset, it often heals a shade darker.
What else it could be
Not every dark line above the lip is melasma. The cause changes what helps, so it is worth sorting out first.
Fine dark hair is the top mix-up. A thick layer of soft hair casts a real shadow on the skin.
Run a finger over it, or look in bright side light. If you feel or see hair, the skin under it may be your normal color.
Next is darkening after the skin was upset. This follows waxing, threading, laser, acne, a cold sore, or a rash.
It often traces the exact spot that was sore. It fades on its own over months if you leave that area alone.
A reaction to a product can look the same. Fragrance, lip balm, toothpaste, mouthwash and hair dye can all do it.
The clue is that it itched, burned or looked pink first. A grey brown stain can stay long after the itch is gone.
Some medicines darken the skin. Certain acne antibiotics, seizure drugs and malaria drugs are known for this.
Hormone pills can bring on true melasma. Check if the mark started within a few months of a new drug.
A rare but serious cause is a low output from the adrenal glands. Then the darkening is not just the lip.
Gums, palm lines, scars, knuckles and old scars go darker too. It comes with deep tiredness, weight loss, dizziness on standing, and a craving for salt.
Hormone trouble such as polycystic ovary syndrome can bring coarse dark hair and dark patches together. Missed periods, acne and dark velvet skin on the neck point that way.
One last group is single spots, not a band. A mole, a sun spot or a new growth sits on one side only. If it is raised, changing, or has ragged edges, treat it as a spot to get checked, not as melasma.
How to read the grades below
The options below come from our page on Melasma. Each one carries two labels.
The first label is the evidence grade. A means strong trials in people, B means smaller or mixed studies, and C means early or limited findings. D means lab work only, and “insufficient” means the research cannot settle it yet.
The second label is the traditional tier. T3 means long use in more than one tradition, T2 means long use in one, and T1 means known use. T0 means no such record.
These grades come from research on Melasma, the parent Health Topic, not on dark shadow above my upper lip.
A grade tells you how strong the research is, not how well something will work for you. Talk to a doctor or pharmacist before you start anything, above all if you take other medicines.
What to try first
Start with sun cover. Nothing else works well while the sun keeps switching the color back on. A broad spectrum sun cream in the morning, with more put on at midday, is one option some people use.
A tinted sun cream with iron oxide also blocks visible light. Visible light drives melasma too, so this helps more than a clear one. A wide hat or a light face scarf adds cover on hot days.
Stop what rubs that strip. Skip waxing and threading there while the mark is active. Trim or shave fine hair instead, and drop harsh scrubs and stinging toners.
If hormones may be part of it, talk to your doctor about your pill or patch. Do not stop it on your own. There may be another option that suits you better.
For products, two have the top mark. Tranexamic Acid Serum has an evidence grade A, traditional tier T0. Azelaic acid also has an evidence grade A, traditional tier T0.
Melatonin has an evidence grade A, traditional tier T0. It has been looked at both as a cream and as a pill. Ask your doctor before you take it by mouth.
Next come the B grades. Vitamin C Topical has an evidence grade B, traditional tier T0. Licorice root (Glycyrrhiza glabra) has an evidence grade B, traditional tier T3, so it also has long folk use.
Postbiotic (heat-killed bacteria) has an evidence grade B, traditional tier T0. Vitamin C (Effervescent Powder) has an evidence grade B, traditional tier T0, and is taken by mouth.
Two have weaker proof. Alpha-Arbutin has an evidence grade C, traditional tier T0. Cordyceps has an evidence grade C, traditional tier T3, which means long folk use but thin trial proof.
Three do not have enough proof to grade. Niacinamide (Nicotinamide) is evidence grade insufficient, traditional tier T0.
Glutathione is evidence grade insufficient, traditional tier T0. Acupuncture is evidence grade insufficient, traditional tier T3, so it rests on tradition, not trials.
Add one thing at a time. Dab it on your jaw for three days first to check for stinging. Melasma comes back easily, so slow and gentle beats strong and fast.
How long it takes
Melasma moves slowly. Most people need 8 to 12 weeks of daily care before they see a clear change. Nothing works in a week.
Taking a photo now, and then one each month in the same light, is one way to follow any change. Small fading is hard to spot in the mirror day by day. The photo tells you the truth.
If hormones were the trigger, the mark may fade after birth or after a pill change. That can take 6 months or more. Some marks stay and need ongoing care.
Melasma tends to come back each summer. Keeping up sun cover is what holds any gain you make. No product here can promise a set result.
