What caused a sudden hyperpigmentation near my mouth?

Question

Hello doctor,

I have recently noticed sudden hyperpigmentation around both sides of my mouth, and the area appears very dry and noticeably different from the rest of my skin. I’m concerned about these changes.

Please help.

Thank you.

Hi,

Welcome to icliniq.com.

I read your query and can understand your concern.

Sudden pigmentation and dryness around the mouth can be concerning, especially if it comes on quite suddenly. Please be assured that this can happen fairly commonly and often can be managed with appropriate care.

Sudden darkening around the mouth can be due to:

Dryness or irritation of the skin from weather changes, toothpaste, lip-licking, or some products.
Perioral dermatitis or eczema.
Post-inflammatory pigmentation due to minor, unnoticed irritation.
Vitamin deficiencies (such as B12).
Hormonal or metabolic factors (sometimes related to thyroid or blood sugar levels).

In the meantime, you might try:

Regular moisturizing with a fragrance-free, gentle cream (such as ceramide-based creams, or petroleum jelly at night)
Avoid using harsh face washes, scrubs, or any new skincare products for a few days.
Using sunscreen every day, even around the mouth, to prevent further darkening.

If the pigmentation remains after two to three weeks or increases in intensity, a dermatologist can evaluate the situation for conditions like perioral dermatitis, melasma, or nutritional deficiency and may prescribe specific treatments.

I hope the information helps.
