Why Is the Skin Around My Mouth Getting Dark?

Have noticeable darkness around your upper lip, mouth corners, or chin? Perioral pigmentation, or melasma mustache, can make your complexion look uneven, so you may be looking for a solution to regain your social confidence.

Repeated sun exposure can be one possible reason. Others include hormonal changes, post-inflammatory pigmentation, irritation, dryness, frequent lip licking, and certain skincare/cosmetic products.

Identifying the exact underlying cause of Melasma Mustache is important for appropriate treatment. Otherwise, the wrong treatment may irritate the skin and make the darkness around the mouth more prominent.

If you are searching for melasma mustache pigmentation treatment in Bangalore to fade the darkness around your mouth, your first step should be understanding why the skin around your mouth becomes dark so you can find the best solution.  

Possible Reasons for Having Dark Skin Around the Mouth

Skin gets darker when the specialized skin cells called melanocytes produce more melanin, a colored pigment responsible for natural skin color. Multiple factors trigger this melanin overproduction around the mouth.

Sometimes more than one trigger occurs simultaneously.

Here are dermatologist-identified reasons for skin darkening around the mouth:

1. Cumulative UV Exposure: Your skin has a natural defense against the sun’s UV rays: eumelanin. With repeated or prolonged direct sun exposure, the skin produces more melanin to protect itself from UV damage. This, in turn, makes the skin darker and existing pigmentation more visible.
2. Post-Inflammatory Hyperpigmentation: This happens when you experience acne, rashes, irritation, or excessive dryness around your mouth before skin darkening. These concerns lead to inflamed skin, which naturally stimulates melanin production, usually in medium to deep skin tones. Post-inflammatory hyperpigmentation may gradually fade as inflammation subsides, but this can take several months.
3. Melasma: A type of facial pigmentation, most common after pregnancy. It shows up as symmetrical brown patches on sun- and visible-light-exposed areas, including around the mouth, due to hormonal changes and genetic factors.
4. Frequent Lip Licking: When lips are dry or irritated, repeated licking can leave the surrounding skin dry and irritated from saliva. This habit results in darker skin around the lips. Therefore, keeping the lips and surrounding skin well moisturized is important.
5. Aggressive/Irritating Skincare Products or Cosmetics: The skin around the mouth is delicate. So, harsh scrubs, strong exfoliants, bleaching products, inappropriate cosmetics, or multiple skincare ingredients may cause burning, peeling, redness, dryness, inflammation, and subsequent skin darkening.
6. Upper Lip and Chin Hair Removal with Shaving, Threading, or Waxing: Repeated hair removal can cause microscopic irritation around the mouth. For those who are susceptible to facial pigmentation, repeated irritation can cause post-inflammatory hyperpigmentation. Therefore, a gentle hair removal approach suited to your skin type is recommended.
7. Dryness Around the Mouth: Dry, cracked, or irritated skin around the mouth can become inflamed and eventually darken. This is common during cold, dry winter days. Also, acne medications, harsh cleansers, strong exfoliants, and inadequate moisturization can compromise the skin barrier and cause pigmentation.

Dermatologist-Recommended Tips to Prevent Worse Skin Darkening Around Mouth

• Wear broad-spectrum sunscreen SPF 50 or higher daily, and reapply when sweating or during extended outdoor exposure, regardless of the weather.
• Do not excessively scrub or exfoliate the skin.
• Keep the skin well moisturized.
• Break the habit of repeatedly licking your lips.
• Use gentle skincare products.
• Promptly treat acne or rashes.
• Avoid picking or scratching irritated skin.
• Be careful with repeated hair-removal methods.
• Strictly follow a gentle skincare routine.

Professional Treatments for Dark Skin Around the Mouth

Here are some:

1. Simple, Personalized Skincare: Dermatologists recommend a gentle cleanser, a suitable moisturizer, and sunscreen to keep the skin less irritated and prevent further pigmentation.
2. Pigmentation-Reducing Topicals: Based on pigmentation type, severity, and the sensitivity of the mouth area, dermatologists recommend azelaic acid, kojic acid, Vitamin C, ret-inoids, or other medical-grade ingredients.
3. Chemical Peels: Selected exfoliating acids may be used to improve superficial skin darkening. With carefully chosen mild peels, the pigmented skin can be peeled off to reveal naturally lighter, fresher skin underneath.
4. Light-based/Laser Treatments: In some cases, skin darkening around the mouth can lighten with targeted thermal breakdown of excess melanin using laser or skin resurfacing. A professional needs the right device and energy setting, along with careful application, to avoid aggressive treatment or worsening pigmentation.

When to See a Dermatologist for Skin Darkening Around Mouth?

Go for a professional evaluation if:

1. The skin darkening is worsening.
2. The skin darkening is symmetrical, probably melasma.
3. At-home treatments are not improving the skin darkening.
4. Skin darkening persists for several months, despite proper skincare.
5. Accompanying symptoms include rash, itching, burning, or scaling.
6. Your pigmented skin needs professional procedures like chemical peels or laser treatment.
