The dark spots around your mouth can be caused by several factors. While they can be bothersome, the good news is that these marks are treatable. This article will guide you through diagnosing and treating dark skin around the mouth.
Steps
Diagnosing dark skin around the mouth

Understand why dark spots appear around the mouth. These spots are often the result of excess melanin darkening specific areas of the skin. Melanin levels can rise due to internal and external triggers. This condition is known as hyperpigmentation. Triggers can include sun exposure, melasma, and skin inflammation.
- Age spots (sunburn spots): These clusters of dark brown marks can take months or even years to appear on skin exposed to the sun. Once they appear, they usually don’t disappear without treatment. This pigmentation change occurs near the skin’s surface and can be treated with creams and scrubs. Using sunscreen regularly helps prevent age spots from forming or worsening.
- Melasma (Chloasma): These symmetrical dark spots appear due to hormonal changes (such as from birth control pills or during pregnancy). When these hormones are exposed to sunlight, dark spots can develop on the cheeks, forehead, or upper lip. This type of hyperpigmentation often reoccurs, even after treatment.
- Post-inflammatory hyperpigmentation: If you have darker skin, you may develop dark spots after burns, acne, or other skin damage. In these cases, melanin lies deeper in the skin, and the dark spots may take 6-12 months to fade.

Consider the climate factors. The skin around your mouth tends to be drier in colder seasons. Some people often lick their lips to moisturize, which can lead to darkening of the skin. If you aren’t frequently exposed to sunlight, the skin around your mouth can become excessively wet and darken.

Understand that the skin around the mouth is very thin. Thin skin can result in discoloration, dryness, and wrinkles around the mouth. These issues don't penetrate deep into the skin, so they don't require invasive treatments. Discoloration can be easily addressed with treatments or exfoliation.

Consult a dermatologist. If you are unsure of the cause of darkening around your mouth, it’s best to see a doctor for a diagnosis and treatment recommendations. Skin discoloration can be an early sign of skin cancer or other serious conditions, so it’s always advisable to seek medical advice to assess your symptoms.
Creams, exfoliation, and prescription treatments

Exfoliate daily with a gentle product. Exfoliating products help remove dead skin cells and gradually lighten the dark skin around your mouth. Apply a small amount of exfoliator (about the size of a pea) to a damp cloth. Gently rub the cloth on your face to remove pigmented skin cells and cleanse the skin.
- You can find exfoliating products at pharmacies, cosmetics stores, and specialty shops for skincare. Be sure to read product reviews before purchasing. Some exfoliators are formulated to treat acne and other skin issues; they often use acids and chemicals to cleanse the skin.

Use over-the-counter skin brightening creams. You can find brightening and moisturizing products at pharmacies and beauty stores. Look for creams containing vitamin C, kojic acid (extracted from certain fungi), arbutin (from the bearberry plant), azelaic acid (from wheat, barley, and rye), licorice extract, niacinamide, or grape seed extract. These ingredients help block the tyrosinase enzyme, which is necessary for melanin production. Apply a thin layer to the skin around your mouth. Follow the instructions and do not use the brightening cream for more than 3 weeks.
- Kojic acid is a common treatment but can irritate the skin, so caution is advised.

Consider using prescription creams. If the dark skin doesn't fade, a dermatologist might prescribe a topical medication like Hydroquinone. Hydroquinone helps reduce pigment-producing cells and slows the production of tyrosinase in the skin. The dark spots usually fade quickly once the pigment production decreases.
- Animal studies have shown a link between Hydroquinone and cancer, but the animals were fed or injected with the drug. In contrast, human treatments primarily involve topical applications, and there is no evidence suggesting Hydroquinone is toxic to humans. As a result, many dermatologists disagree with the notion that Hydroquinone is linked to cancer.
- Most patients notice the first signs of lighter skin within a few days, and the effects generally last for up to 6 weeks. After treatment, you may switch to over-the-counter creams to maintain lighter skin tone.

Try laser treatment. Laser treatments like Fraxel are often one of the most effective and long-lasting methods to address surface-level discoloration. However, laser results are not always permanent. Effectiveness can vary depending on genetic factors, UV exposure, and your skincare routine. Laser treatments also tend to be more expensive compared to other methods.

Consider using glycolic acid or salicylic acid peel masks. A dermatologist may recommend using peel masks to reach and treat damaged skin cells deeper within the skin. Note that the effects of peel masks are not permanent. Depending on genetic factors and UV exposure, dark spots may reappear after a few weeks or even years. Avoid sun exposure and treat dark spots early to ensure long-term effectiveness of the treatment.
Natural Ingredients

Brighten your skin naturally with lemon juice. Mix the juice of 1/4 lemon with a tablespoon of honey or yogurt in a small bowl. Cleanse your face with warm water to open your pores. Apply a thick layer of the mixture to the darkened skin and wait for the mask to dry. Gently wash your skin with warm water.
- You can also mix 2 tablespoons of lemon juice and sugar, apply it to a cotton pad, and gently rub it on the dark skin for 2-3 minutes, then rinse with water.
- For added effectiveness, cut a lemon in half and squeeze the juice onto the dark skin. Rinse after 10 minutes.
- Avoid sun exposure after using lemon. It’s best to use lemon at night when you’re not exposed to UV rays.

Use aloe vera. Apply aloe vera gel or fresh aloe vera extract to the darkened skin. This method helps moisturize and rejuvenate the skin. Aloe vera is particularly effective for skin darkened by sun exposure.

Mix grated cucumber with lemon juice. Combine equal parts of grated cucumber and lemon juice to create a paste. Apply the mixture around the mouth and leave it on for about 20 minutes. Rinse with warm water. This remedy helps restore the skin’s appearance.

Apply a turmeric and flour mask. Prepare a mixture of 1 gram of flour, 1 teaspoon of turmeric powder, and 1/2 cup of yogurt. Apply the mixture to the dark skin and leave it on for about 20 minutes before rinsing with warm water.

Exfoliate with oatmeal. Create an exfoliating mixture with 1 tablespoon of oatmeal, 1 teaspoon of tomato juice, and 1 teaspoon of yogurt. Mix the ingredients together. Gently scrub the mixture onto your skin for 3-5 minutes, then wash off after 15 minutes.
Advice
- Remember to keep your skin moisturized.
- Be gentle when rubbing. Avoid scrubbing too hard to prevent discomfort or scarring around your mouth.
- Exfoliating may feel uncomfortable at first, but you’ll get used to it.
